    JUMMEC, 1996;1:17-19.
    The conventional use of aminoglycoside antibiotics has several disadvantages including the need for regular pre- and post-dose assaying and the risks of toxicity. Achieving a therapeutic and non-toxic serum concentration may be difficult in many patients especially those with severe sepsis. Correct timing of doses and assays is essential, but this is often difficult to achieve. Many of these difficulties may be remedied by the use of once daily dosing. This dosing schedule appears to be equally effective as the conventional method and i s also less toxic. There are many other advantages including the need for less assays and venepuncture resulting in reduced costs. KEYWORDS: Aminoglycosides, antibiotic therapy, toxicity, therapeutic monitoring

    JUMMEC, 1999;4:103-109.
    A restropective study on a case of recurent salmonellosis in a 3 month old child due to Salmonella bovismorbificans and Salmonella matopeni was carried out using pulsed field gel electrophoresis (PFGE) and antibiotic susceptibility analysis. PFGE clearly distinguished the two serovars and that the recurrent infection was shown to associated with variant forms of Salmonella bovismorbificans. The chromosomal changes detected among the seqential isolates of Salmonella bovismorbificans appeared to be associated with varing antibiogram patterns. The study also showed that the recurrent infection in the patient could be related to prolonged antibiotic therapy.

  4. Peroxymonosulfate activation by a metal-free biochar for sulfonamide antibiotic removal in water and associated bacterial community composition
    Hung CM, Chen CW, Huang CP, Shiung Lam S, Dong CD
    Bioresour Technol, 2022 Jan;343:126082.
    PMID: 34610427 DOI: 10.1016/j.biortech.2021.126082
    Antibiotic sulfamethoxazole (SMX) has been commonly found in various water matrices, therefore effective decontamination method is urgently needed. Metal-free pristine coconut-shell-derived biochar (CSBC), synthesized by thermochemical conversion at 700 °C, was used for activating peroxymonosulfate (PMS), an oxidant, to degrade SMX, a sulfonamide antibiotic, in water. SMX degradation, maximized at 0.05 mM concentration, was 85% in 30 min at pH 5.0 in the presence of 150 mg L-1 of CSBC. Remarkably, SMX removal reached 99% in a chloride-rich CSBC/PMS system. SMX degradation was mainly attributed to the role of CSBC in enhancing PMS activation to produce combined radical (SO4•-/HO•) and nonradical (1O2) reaction pathways. The most abundant genus in the CSBC/PMS system was Methylotenera, which belonged to the Proteobacteria phylum. Thus, from a perspective of biowaste-to-resource recycling and circular bioeconomy view point, CSBC is a potential catalytic activator of PMS for the removal of sulfonamide antibiotics from aqueous environments.

  5. Tetracycline removal in granulation: Influence of extracellular polymers substances, structure, and metabolic function of microbial community
    Yan L, Chen W, Wang C, Liu S, Liu C, Yu L, et al.
    Chemosphere, 2022 Feb;288(Pt 2):132510.

    Tetracycline is a potentially hazardous residual antibiotic detected in various sewages. High concentration (mg/L) of tetracycline is found in pharmaceutical/hospital wastewater and wastewater derived from livestock and poultry. So far, only antibiotics in μg/L level have been reported in granulation of aerobic sludge during wastewater treatment, but its effects in high concentration are rarely reported. In this study, the influence of tetracycline in high concentration (∼2 mg/L) on the formation of granular sludge, structure, and metabolic function of the microbial community during the granulation of aerobic sludge was investigated to improve the understanding of the aerobic granular sludge formation under high-level of tetracycline. The role of extracellular polymers substances (EPSs) derived from granular sludge in the granulation and tetracycline removal process was also investigated, showing that tetracycline improved the relative hydrophobicity, flocculability and protein/polysaccharide ratio of EPSs, accelerating the granulation of sludge. Succession of microbial communities occurred during the domestication of functional bacteria present in the sludge and was accompanied with regulation of metabolic function. The addition of tetracycline lead to an increase of tetracycline-degrading bacteria or antibiotic resistance genus. Those findings provide new perspectives of the influence of tetracycline on aerobic sludge granulation and the removal mechanism of tetracycline.

  8. Fabrication of green composite hand knitted silk mesh reinforced with silk hydrogel
    Bokhari N, Ali A, Yasmeen A, Khalid H, Safi SZ, Sharif F
    Int J Biol Macromol, 2023 Dec 31;253(Pt 6):127284.
    PMID: 37806415 DOI: 10.1016/j.ijbiomac.2023.127284
    Soft tissue defects like hernia and post-surgical fistula formation can be resolved with modern biomaterials in the form of meshes without post-operative complications. In the present study hand knitted silk meshes were surface coated with regenerated silk fibroin hydrogel and pure natural extracts. Two phytochemicals (Licorice extract (LE) and Bearberry extract (BE)) and the two honeybee products (royal jelly (RJ) and honey (HE)) were incorporated separately to induce antibacterial, anti-inflammatory, and wound healing ability to the silk hydrogel coated knitted silk meshes. Meshes were dip coated with a blend of 4 % silk hydrogel (w/v) and 5 % extracts. Dried modified meshes were characterized using SEM, DMA, GC-MS and FTIR. Antimicrobial testing, in-vitro cytotoxicity, in-vitro wound healing and Q-RT-PCR were also performed. SEM analysis concluded that presence of coating reduced the pore size up to 47.7 % whereas, fiber diameter was increased up to 17.9 % as compared to the control. The presence of coating on the mesh improved the mechanical strength/Young's modulus by 1602.8 %, UTS by 451.7 % and reduced the % strain by 51.12 %. Sustained release of extracts from MHRJ (62.9 % up to 72 h) confirmed that it can induce antibacterial activity against surgical infections. Cytocompatibility testing and gene expression results suggest that out of four variables MHRJ presented best cell viability, % wound closure and expression of wound healing marker genes. In-vivo analyses in rat hernia model were carried out using only MHRJ variant, which also confirmed the non- toxic nature and wound healing characteristics of the modified mesh. The improved cell proliferation and activated wound healing in vitro and in vivo suggested that MHRJ could be a valuable candidate to promote cell infiltration and activate soft tissue and hernia repair as a biomedical implant.

  9. Fulltext Fungicidal effectiveness of super-oxidized solution in vitro: potential implications for wound care
    Krishnen R, Muniandy S
    Wounds, 2023 Aug;35(8):E243-E247.
    PMID: 37643448 DOI: 10.25270/wnds/23017
    INTRODUCTION: Drug-resistant fungal infections in chronic wounds represent a major clinical challenge to clinicians. Fungal infections delay wound healing by prolonging inflammation and encouraging biofilm formation, which protects microbes against host defenses and anti-infective medications. As such, interventions that prevent and control nosocomial fungal infections without interfering with the wound healing process are increasingly required. Although conventional antiseptics can effectively exert fungicidal effects, they also have adverse effects on human cells. SOS is a well-known bactericidal agent that enhances the wound healing process, especially for chronic wounds. However, few studies have evaluated the antimicrobial activity of SOS on fungi.

    OBJECTIVE: The objective of this study was to evaluate whether SOS exerts fungicidal activities against common fungal species.

    MATERIALS AND METHODS: The efficacy of SOS was tested against 6 fungal species (Candida albicans, Candida auris, Candida tropicalis, Candida parapsilosis, Sporothrix schenckii, Trichophyton mentagrophytes) using an in vitro time-kill assay.

    RESULTS: SOS achieved 99.9999% reduction of all tested fungi within 1 minute of exposure.

    CONCLUSIONS: This study shows that SOS may be an effective tool for the prevention and control of fungal infections.

    Rare flavonoids, a special subclass of naturally occurring flavonoids with diverse structures including pterocarpans, aurones, neoflavonoids, homoisoflavones, diphenylpropanes, rotenoids and 2-phenylethyl-chromones. They are mainly found in legumes with numerous health benefits. Rare flavonoids are regarded as minor flavonoids due to their very limited abundance in nature. This review gives an overview of the natural occurrences of rare flavonoids from previous literatures. Recent findings on the biosynthesis of rare flavonoids have been updated by describing their structural characteristics and classifications. Recent findings on the health benefits of rare flavonoids have also been compiled and discussed. Natural rare flavonoids with various characteristics from different subclasses from plant-based food sources are stated. They show a wide range of health benefits, including antibacterial, anticancer, anti-osteoporosis and antiviral activities. Studies reviewed suggest that rare flavonoids possessing different skeletons demonstrate different characteristic bioactivities by discussing their mechanism of actions and structure-activity relationships. Besides, recent advances on the biosynthesis of rare flavonoids, such as pterocarpans, rotenoids and aurones are well-known, while the biosynthesis of other subclasses remain unknown. The perspectives and further applications of rare flavonoids using metabolic engineering strategies also be expected.

  11. Comparing different versions of the Yoon-Nelson model in describing organic micropollutant adsorption within fixed bed adsorbers
    Chu KH, Hashim MA
    Environ Sci Pollut Res Int, 2024 Mar;31(14):21136-21143.
    PMID: 38386161 DOI: 10.1007/s11356-024-32450-7
    The Yoon-Nelson model serves as a widely used tool for describing the breakthrough behavior of organic micropollutants within fixed bed adsorbers. This study aims to augment its modeling efficacy through two proposed refinements found in the literature: a logarithmic transformation and the incorporation of steric hindrance effects. We systematically evaluated the original Yoon-Nelson model alongside the modified versions, using breakthrough data associated with micropollutant adsorption on solid materials. Three distinct cases were scrutinized: (1) caffeine adsorption on activated carbon; (2) tetracycline adsorption on hierarchical porous carbon; and (3) diclofenac adsorption on organoclay. While all three models demonstrated comparable performance with highly symmetric breakthrough data in case 1, their efficacy diverged significantly when confronted with strongly asymmetric breakthrough data in cases 2 and 3. The original Yoon-Nelson model and the logarithmically modified version fell short in accurately representing these intricate breakthrough curves. In contrast, the version incorporating steric hindrance effects showcased substantial accuracy, outperforming other models in capturing the complexities of asymmetric breakthrough data. This advancement markedly enhances the modeling accuracy and versatility of the Yoon-Nelson model, particularly in assessing the dynamic behavior of organic micropollutants within fixed bed adsorbers.

  14. The production and characterisation of trichotoxin peptaibols, by Trichoderma asperellum
    Chutrakul C, Alcocer M, Bailey K, Peberdy JF
    Chem Biodivers, 2008 Sep;5(9):1694-706.
    PMID: 18816522 DOI: 10.1002/cbdv.200890158
    Trichoderma spp. are regularly found as a constituent of the mycoflora of many soils and are noted for their antagonistic activity against bacteria and other fungi. This latter property is the basis for the widespread interest in their use in the biological control of soil-borne fungal plant pathogens. This antagonism is partly based on their ability to produce an impressive inventory of secondary metabolites. An important group of bioactive metabolites produced by Trichoderma spp. are the non-ribosomal peptides (NRPs), especially the peptaibols. A virulent antagonistic strain, T. asperellum, which had been used in biological control strategies in Malaysia and previously examined for mycolytic enzyme production, has been studied for its potential for peptaibol production. The present research demonstrated the ability of T. asperellum to produce at least two metabolites which were identified as acid trichotoxin 1704E (Ac-Aib-Gly-Aib-Leu-Aib-Gln-Aib-Aib-Aib-Ala-Ala-Aib-Pro-Leu-Aib-Iva-Glu-Vol) and neutral trichotoxin 1717A (Ac-Aib-Gly-Aib-Leu-Aib-Gln-Aib-Aib-Aib-Ala-Aib-Aib-Pro-Leu-Aib-Iva-Gln-Vol). Addition of free Aib to the culture medium enhanced the production of trichotoxins. Biological activity of these substances was investigated against Bacillus stearothermophilus. The general characteristics of peptaibols, also found in the trichotoxins, include the presence of high proportions of the uncommon amino acid Aib, the protection of the N- and C-termini by an acetyl group and reduction of the C-terminus to 2-amino alcohols, respectively, amphipathy and microheterogeneity.

  15. Oritavancin - a new semisynthetic lipoglycopeptide agent to tackle the challenge of resistant gram positive pathogens
    Das B, Sarkar C, Schachter J
    Pak J Pharm Sci, 2013 Sep;26(5):1045-55.
    PMID: 24035967
    Natural glycopeptide antibiotics like vancomycin and teicoplanin have played a significant role in countering the threat posed by Gram-positive bacterial infections. The emergence of resistance to glycopeptides among enterococci and staphylococci has prompted the search for second-generation drugs of this class and semi-synthetic derivatives are currently under clinical trials. Antimicrobial resistance among Gram-positive organisms has been increasing steadily during the past several decades and the current development of antibiotics falls short of meeting the needs. Oritavancin (LY-333328 diphosphate), a promising novel second-generation semisynthetic lipoglycopeptide, has a mechanism of action similar to that of other glycopeptides. It has concentration-dependent activity against a variety of Gram-positive organisms specially methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-intermediate resistant Staphylococcus aureus (VISA), Streptococcus pneumoniae and vancomycin-resistant enterococcus. It is rapidly bactericidal against many species and in particular for enterococci where vancomycin and teicoplanin are only bacteriostatic even against susceptible strains. The pharmacokinetic profile of oritavancin has not been fully described; however, oritavancin has a long half-life of about 195.4 hours and is slowly eliminated by renal means. Oritavancin is not metabolized by the liver in animals. Oritavancin will most probably be prescribed as a once-daily dose and it demonstrates concentration-dependent bactericidal activity. Oritavancin has demonstrated preliminary safety and efficacy in Phase I and II clinical trials. In a Phase III clinical trial, oritavancin has achieved the primary efficacy end point in the treatment of complicated Gram-positive skin and skin-structure infections. To date, adverse events have been mild and limited; the most common being administration site complaints, headache, rhinitis, dry skin, pain, increases in liver transaminases and accumulation of free cholesterol and phospholipids in phagocytic (macrophages) and nonphagocytic (fibroblast) cells. Oritavancin appears to be a promising antimicrobial alternative to vancomycin (with additional activity against Staphylococcus and Enterococcus resistant to vancomycin) for the treatment of complicated Gram-positive skin and skin-structure infections. Additional clinical data are required to fully explore its use.

  17. Fulltext Antibiotics dispensing for URTIs by community pharmacists (CPs) and general medical practitioners in Penang, Malaysia: A comparative study using simulated patients (SPs)
    Alabid AH, Ibrahim MI, Hassali MA
    J Clin Diagn Res, 2014 Jan;8(1):119-23.
    PMID: 24596741 DOI: 10.7860/JCDR/2014/6199.3923
    BACKGROUND: In Malaysia, doctors in private clinics (often called dispensing doctors) are permitted to dispense medicines. This potentially may compromise rational dispensing of medicines in general and antibiotics in particular.
    AIM: This study explored, assessed and compared dispensing of antibiotics between Community Pharmacist (CP) and General Practitioners (GPs) regarding symptomatic diagnosis, antibiotic categories, adherence to therapeutic doses and promotion of generic antibiotics.
    METHOD: The study used trained Simulated Patients (SPs), who used a scenario of common cold symptoms at GP private clinics and community pharmacies to observe and explore the practice of antibiotics dispensing. The study was conducted within the period of May to September 2011 in Penang, Malaysia. The data was analysed using descriptive statistics, Chi-square and Fisher's Exact Tests at alpha level of 0.05.
    RESULTS: GPs dispensed more antibiotics than CPs (p= 0.001) for common cold symptoms. They dispensed more Amoxicillin (n = 14, 35%) than CPs (n = 11, 11%) (p < 0.001) and more Tetracycline (n = 3, 7.5%) while no CP dispensed this category (p = 0.022). On the other hand, CPs (n = 11, 11%) suggested brand antibiotics where as GPs dispensed only generic antibiotics (p < 0.001). Generally GPs comply better with the symptomatic diagnosis standard e.g. when asking SPs about the symptoms they had, all GPs (n = 40, 100%) complied better with this standard. Despite that, they dispensed more antibiotics (n = 26, 65%) than CPs (n = 29, 29%) (p = 0.001). GPs (n = 22, 55%) also are better than CPs (n = 16, 16%) in adherence to therapeutic doses (p< 0.001).
    CONCLUSION: Findings showed poor adherence to rational dispensing of antibiotics by both providers. Although, GPs adhere better to symptomatic diagnosis and therapeutic dosing of antibiotics than CPs, they unnecessarily prescribe and dispense more antibiotics for Upper respiratory tract infection (URTI) symptoms. Establishing prescription guidance and regulatory actions, especially for URTIs treatment, and separating of medication dispensing are seemed to be crucial steps for the reform.

    Curcuma longa L. (Zingiberaceae family) and its polyphenolic compound curcumin have been subjected to a variety of antimicrobial investigations due to extensive traditional uses and low side effects. Antimicrobial activities for curcumin and rhizome extract of C. longa against different bacteria, viruses, fungi, and parasites have been reported. The promising results for antimicrobial activity of curcumin made it a good candidate to enhance the inhibitory effect of existing antimicrobial agents through synergism. Indeed, different investigations have been done to increase the antimicrobial activity of curcumin, including synthesis of different chemical derivatives to increase its water solubility as well ass cell up take of curcumin. This review aims to summarize previous antimicrobial studies of curcumin towards its application in the future studies as a natural antimicrobial agent.

    Klebsiella pneumoniae is one of the most common Gram-negative bacterial pathogens in clinical practice. It is associated with a wide range of disorders, ranging from superficial skin and soft tissue infections to potentially fatal sepsis in the lungs and blood stream. Quorum sensing, or bacterial cell-cell communication, refers to population density-dependent gene expression modulation. Quorum sensing in Proteobacteria relies on the production and sensing of signaling molecules which are mostly N-acylhomoserine lactones. Here, we report the identification of a multidrug resistant clinical isolate, K. pneumoniae strain CSG20, using matrix-assisted laser desorption ionization-time-of-flight (MALDI-TOF) mass spectrometry. We further confirmed quorum sensing activity in this strain with the use of high resolution tandem liquid chromatography quadrupole mass spectrometry and provided evidence K. pneumoniae strain CSG20 produced N-hexanoyl-homoserine lactone (C6-HSL). To the best of our knowledge, this is the first report on the production of N-hexanoylhomoserine lactone (C6-HSL) in clinical isolate K. pneumoniae.

  20. Fulltext A cross sectional study of public knowledge and attitude towards antibiotics in Putrajaya, Malaysia
    Lim KK, Teh CC
    South Med Rev, 2012 Dec;5(2):26-33.
    PMID: 23532680
    OBJECTIVE: The objective of the study was to assess public knowledge and attitudes regarding antibiotic utilization in Putrajaya, Malaysia.
    METHODS: A self-administered questionnaire survey was conducted among public attending a local hospital. The four-part questionnaire collected responses on demographic characteristics, recent use of antibiotics, knowledge and attitude statements. Cronbach's alpha for knowledge and attitude statements were 0.68 and 0.74 respectively. Only questionnaires with complete responses were analysed. General linear modelling was used to identify demographic characteristics which contributed significantly to knowledge and attitude. Multiple logistic regression was used to determine the adjusted odds ratios of obtaining an inappropriate response for each knowledge and attitude statement. The relationship between antibiotic knowledge and attitude was examined using Pearson's correlation and correlation between related statements was performed using the Chi-square test. In all statistical analyses, a p-value of < 0.05 was considered statistically significant.
    RESULTS: There was positive correlation (p<0.001) between mean knowledge (6.07±2.52) and attitude scores (5.59±1.67). Highest education level (p<0.001) and healthcare-related occupation (p=0.001) contributed significantly to knowledge. Gender (p=0.010), race (p=0.005), highest education level (p<0.001), employment status (p=0.016) and healthcare-related occupation (p=0.005) contributed significantly to attitude. The differences in score between demographic groups were small. Misconceptions that antibiotics would work on both bacterial and viral infections were reported. Approximately three quarters of respondents expected antibiotics for treatment of coughs and colds. Close to two thirds (60%) believed that taking antibiotics would improve recovery. Several demographic groups were identified as 'high risk' with respect to gaps in knowledge and attitude.
    CONCLUSIONS: This study has identified important knowledge and attitude gaps as well as people 'at risk'. These findings would be useful in strategizing targeted antibiotic awareness campaigns and patient counselling.
