    Swabs from the brain, eyes and kidneys of tilapia from 11 farms were collected for a period of 2 years. They were grown on blood agar before cultures of suspected Staphylococcus aureus were subjected to ABI STAPH Detection Kit and PCR for identification. They were then grown on oxacillin resistance screening agar base (ORSAB) and subjected to PCR using the MRSA 17 kb forward and reverse primers to identify the methicillin-resistant S. aureus (MRSA). A total of 559 isolates of Staphylococcus spp. were obtained, from which 198 (35%) isolates were identified as S. aureus. Of the 198 S. aureus isolated from tilapias, 98 (50%) were identified as methicillin-resistant S. aureus (MRSA). Since global spread of multi-drug-resistant bacteria has increased in the past decade, this new finding in fish should be of concern.

    This study aimed to determine the ability of Persea americana (Mill.) or avocado peels ethanolic extract and its fractions to cause bacterial cell leakage in Staphylococcus aureus. The interaction of antibacterial compound with bacterial cells induces several changes leading to the damage of membrane permeability, followed by intracellular bacterial cell leakage. The experiment started with the determination of minimum inhibitory concentration and minimum bactericidal concentration by micro dilution method. Following the determination of MIC and MBC values, the samples, at the concentrations of 1xMIC and 2xMIC, were tested and analyzed by UV-Vis spectrophotometer at 260 and 280 nm to determine the leakage of bacteria cells. The value of K+ ion leakage was determined using atomic absorption spectrophotometry while the value of electrical conductivity was measured by conducto meter to determine the leakage of the cell membrane. The recorded MIC and MBC values of samples were 10% w/v. At the concentrations of 10% and 20% w/v, the samples caused an increase in nucleic acid, protein and DNA levels as well as an increase in extra cellular electrical conductivity. Prolonged exposure of the extract increased the leakage of bacterial cell contents and the electrical conductivity, indicating the damage of bacterial cell membrane.

    Methicillin-resistant Staphylococcus aureus (MRSA) is a prominent pathogen causing invasive infections such as bacteraemia. The continued excessive use of antibiotics to treat MRSA infections has resulted in the evolution of antimicrobial resistant of S. aureus. This study aims to perform a comparative evaluation of changing trends in molecular epidemiology of MRSA and clinical characteristics of patients. This study shows that ST22-MRSA-IV has gradually replaced ST239-MRSA-III as the predominant MRSA clone in the tertiary teaching hospital studied. Independent predictors of mortality among patients included devices in situ at the time of infection, pre-exposure to macrolides, catheter-related bloodstream infection and mono-microbial infection. Hence, our study affirmed community-associated MRSA, which was previously identified from individuals without any exposure to healthcare settings, has now emerged in healthcare settings, causing healthcare-associated MRSA infections.

    An 18-month analysis of 52 percutaneously placed central venous catheters in 48 critically ill children was done. Success rate were 91.7% (33/36) and 93.8% (15/16) for femoral and non-femoral catheters respectively. Presence of hypotension (48.1%) and significant coagulopathy (26.9%) did not affect the success rate significantly. Minor bleeding and venous congestion was seen in 5.5% (2/36) of patients with femoral catheters. Infections were found in 2.7% (1/36) of femoral and 6.6% (1/15) of non-femoral catheters. The low incidence of complications and the relative ease of insertion makes the femoral route the preferred site for trainee medical officers in critically ill children when central access is indicated.

    Twelve cases of purulent pericarditis seen over 6 years are described. Staphylococcus aureus was the most common causative organism (six patients), and a respiratory infection was the most common preceding illness. The chest radiograph and echocardiogram were useful pointers to the diagnosis, but the electrocardiogram was not reliable. Antibiotics, surgical drainage, and pericardiectomy were used in all 12 cases. There was one death (8.3%), which occurred in a patient who was seen late. A review of the literature dealing with the diagnosis and management of this condition is presented. The importance of early diagnosis before a significant degree of cardiac tamponade occurs is noted. Although there is general agreement that surgical drainage is mandatory, the approach, methods of drainage, and extent of pericardial resection have been the subject of some discussion, and at least seven techniques are available. We conclude that pericardiectomy has a definite place in the management of purulent pericarditis.

    In this work, ZnO, CrZnO, RuZnO, and BaZnO nanomaterials were synthesized and characterized in order to study their antibacterial activity. The agar well diffusion, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) assays were used to determine the antibacterial activity of the fabricated nanomaterials against Staphylococcus aureus ATCC 29213, Escherichia coli ATCC35218, Klebsiella pneumoniae ATCC 7000603, and Pseudomonas aeruginosa ATCC 278533. The well-diffusion test revealed significant antibacterial activity against all investigated bacteria when compared to vancomycin at a concentration of 1 mg/mL. The most susceptible bacteria to BaZnO, RuZnO, and CrZnO were Staphylococcus aureus (15.5 ± 0.5 mm), Pseudomonas aeruginosa (19.2 ± 0.5 mm), and Pseudomonas aeruginosa (19.7 ± 0.5), respectively. The MIC values indicated that they were in the range of 0.02 to 0.2 mg/mL. The MBC values showed that the tested bacteria's growth could be inhibited at concentrations ranging from 0.2 to 2.0 mg/mL. According to the MBC/MIC ratio, BaZnO, RuZnO, and CrZnO exhibit bacteriostatic effects and may target bacterial protein synthesis based on the results of the tolerance test. This study shows the efficacy of the above-mentioned nanoparticles on bacterial growth. Further biotechnological and toxicological studies on the nanoparticles fabricated here are recommended to benefit from these findings.

    Pseudomonas aeruginosa is mostly associated with persistent infections and antibiotic resistance as a result of several factors, biofilms one of them. Microorganisms within the polymicrobial biofilm (PMB) reveal various transcriptional profiles and affect each other which might influence their pathogenicity and antibiotic tolerance and subsequent worsening of the biofilm infection. P. aeruginosa within PMB exhibits various behaviours toward other microorganisms, which may enhance or repress the virulence of these microbes. Microbial neighbours, in turn, may affect P. aeruginosa's virulence either positively or negatively. Such interactions among microorganisms lead to emerging persistent and antibiotic-resistant infections. This review highlights the relationship between P. aeruginosa and its microbial neighbours within the PMB in an attempt to better understand the mechanisms of polymicrobial interaction and the correlation between increased exacerbations of infection and the P. aeruginosa-microbe interaction. Researching in the literature that was carried out in vitro either in co-cultures or in the models to simulate the environment at the site of infection suggested that the interplay between P. aeruginosa and other microorganisms is one main reason for the worsening of the infection and which in turn requires a treatment approach different from that followed with P. aeruginosa mono-infection.

    Parotid abscess is uncommon in neonates. It is frequently related to prematurity, prolonged gavage feeding and dehydration. We report a case of a late preterm infant who developed the classical manifestation of unilateral acute Staphylococcus aureus suppurative parotitis progressing to formation of abscess which responded to surgical drainage and antibiotic therapy.

    Vancomycin bead is an important ancillary treatment for osteomyelitis caused by methicillin-resistant Staphylococcus aureus (MRSA). However, red-man syndrome, which can be a life-threatening complication of vancomycin, may occur from the use of vancomycin beads albeit rarely. We report our first case of red-man syndrome caused by vancomycin bead's insertion for chronic osteomyelitis. Symptomatic treatment was not
    effective and removal of the vancomycin beads seems to be the best treatment for this condition.

    We report a case study on a patient who presented with low back and thigh pain of one month duration. He was eventually diagnosed with left thigh pyomyositis. Tissue from thigh grew Staphylococcus aureus. With commencement of antibiotics and surgical drainage, patient made recovery despite prolonged hospital stay. The underlying mechanism of the extensive abscess accompanied by lack of systemic symptoms; is related to relative immunocompromised state of having underlying diabetes mellitus.

    Staphylococcus aureus nasal carriage is a common source of nosocomial infection and colonization. The aim of the present study was to assess the burden of methicillin-resistant S. aureus nasal carriage, its association with factors of interest including its genetic relationships. The prevalence of S. aureus nasal carriage was found to be 28.7%. This study showed that patients with a history of previous antibiotic intake, nasogastric tube, and longer hospitalization had a significantly high risk of being MRSA nasal carriers. The genetic relationship of all 34 nasal MRSA isolates revealed four major clusters of isolates, and there was a relationship between MRSA isolated from inpatients and healthcare workers.
