    Bloodstream infections (bacteraemia) account for approximately 25-30% of febrile episodes in patients with febrile neutropenia (FN). In developed countries, Gram-positive pathogens predominate. Mortality is higher in Gram-negative bacteraemia. A recent study involving 2142 patients with FN was reviewed, including 168 patients with Gram-negative bacteraemia (mortality 18%), 283 patients with Gram-positive bacteraemia (mortality 5%) and 48 patients with polymicrobial bacteraemia (mortality 13%). Among patients who received prophylactic antibiotics, Gram-positive bacteraemia was far more common than Gram-negative bacteraemia (75% vs. 25%), compared with approximately 50% of each in patients without prophylactic antibiotics. Patients with a Multinational Association for Supportive Care in Cancer (MASCC) score <15 had a 36% mortality compared with 3% if the MASCC score was >21. The MASCC score may help risk stratification of patients with FN and bacteraemia, although these data require confirmation. In two series of patients from developing countries (Lebanon and Malaysia), Gram-negative bacteraemia was more common and mortality was higher. In developing countries, Gram-negative bacteraemia may be more frequent due to less use of prophylactic antibiotics and central lines. Laboratory markers may have predictive and prognostic value for bacteraemia in patients at the onset of FN, including mannose-binding lectin, interleukin (IL)-6, IL-8 and procalcitonin, but further studies are required before they can be recommended. New therapies are required to lower the mortality in patients with FN with a high risk for bacteraemia.

    COVID-19 presents with a spectrum of severity, ranging from asymptomatic or mild symptoms to those with acute respiratory distress syndrome. Corticosteroids are widely used for their efficacy in reducing inflammatory responses. However, its use may be limited to patients with immunosuppression. An adjunct therapy for cytokine storm in COVID-19 is extracorporeal blood purification therapies using high adsorptive filters, such as oXiris, to remove cytokines. We share our experience in using continuous renal replacement therapy with oXiris haemofilter as a temporising measure to high-dose corticosteroids in managing cytokine storm in a deteriorating COVID-19 patient with concomitant bacterial infection.

    Biofilm represents one of the crucial factors for the emergence of multi-drug resistance bacterial infections. The high mortality, morbidity and medical device-related infections are associated with biofilm formation, which requires primarily seek alternative treatment strategies. Recently, nanotechnology has emerged as a promising method for eradicating bacterial biofilm-related infection. The efficacy of nanoparticles (NPs) against bacterial infections interest great attention, and the researches on the subject are rapidly increasing. However, the majority of studies continue to focus on the antimicrobial effects of NPs in vitro, while only a few achieved in vivo and very few registered as clinical trials. The present review aimed to organize the scattered available information regarding NPs approach to eradicate bacterial biofilm-related infections. The current review highlighted the advantages and disadvantages associated with this approach, in addition to the challenges that prevent reaching the clinical applications. It was appeared that the production of NPs either as antimicrobials or as drug carriers requires further investigations to overcome the obstacles associated with their kinetic and biocompatibility.

    Biofilms are a natural part of the ecology of the earth. Many biofilms are quite harmful and must be treated or controlled. Other biofilms are beneficial and can be used to help fix serious problems. Biofilms can grow on many different surfaces, including rocks in water, foods, teeth, and various biomedical implants. This bacterial colonization may present the need for additional operations, amputation, or it may even lead to death. The fundamental principles of bacterial cell attachment and biofilm formation are discussed. Biofilms represents a new, wide-open field practice and research that is only going to get hotter with time. Functional organic plasma polymerized coatings are also discussed for their potential as bio-sensitive interfaces, connecting metallic electronic devices with their physiological environments.

    INTRODUCTION: This paper investigates the role of Group II Secretory Phospholipase A2 (sPLA2-IIA) as a biomarker for the diagnosis of sepsis and bacterial infection in adults. Sepsis and bacterial infection are common problems encountered by patients in the hospital and often carry adverse outcomes if not managed early.

    METHODS: Two independent reviewers conducted a comprehensive search using Ovid MEDLINE published from years 1993 to 2016 and SCOPUS published from year 1985 to 2017 to screen for relevant studies. The main inclusion criteria included adult subjects, patients with suspected or confirmed signs of infection and relevant outcomes which looked into the role of sPLA2-IIA in detecting the presence of sepsis and bacterial infection in the subjects.

    RESULTS AND DISCUSSION: Four studies met the inclusion criteria. SPLA2-IIA was found to be effective in detecting the presence of sepsis and bacterial infection in adults. The levels of serum sPLA2-IIA also correlated well with the presence of sepsis and bacterial infection.

    CONCLUSION: This systematic review highlights the role of sPLA2-IIA as a reliable tool to diagnose sepsis and bacterial infection in adult patients. Nonetheless, further studies should be done in the future to provide more compelling evidence on its application in the clinical setting.

    A 60-year old Malay man presented with an intermittent lowgrade fever for 3 days and worsening of right ankle ulcers. He was known to have ischaemic heart disease, diabetes mellitus type 2, hypertension and end stage renal failure and was on regular haemodialysis. The organisms isolated from the peripheral and central blood specimens were identified as Ochrobactrum anthropi, a rarely encountered gramnegative bacillus with a unique antibiotic susceptibility profile. His condition improved after removal of the catheters and administration of antibiotic therapy. This case report highlights the importance of being wary of such rare, opportunistic pathogens and good communication between the microbiologists and the clinicians.

    Chromobacterium violaceum is a gram negative, facultative anaerobic coccobacillus. Human infections are rare and usually occur after exposure to contaminated soil or water. Infections can present with fulminant septicemia, multiple abscesses and rapidly spreading soft tissue infections. Here we present a fatal case of pulmonary Chromobacterium violaceum infection following aspiration of drain water. Treatment with fluroquinolones in combination with either co-trimoxazole or amikacin has been described in successfully treated cases.

    Chromobacterium violaceum infection is rare but causes a high mortality rate particularly in immunosuppressed persons. Since its clinical presentation is non-specific and the diagnosis basically relies upon blood culture and sensitivity, this infection should be considered among the organisms targeted empirically for antibiotic therapy when a cellulitis or rapidly progressive illness follows exposure to water or soil. This is a case of fulminant septicemia caused by this rarely encountered organism.

    Metallo-β-lactamase (MBL) is an enzyme produced by clinically important bacteria that can inactivate many commonly used antibiotics, making them a significant concern in treating bacterial infections and the risk of having high antibiotic resistance issues among the community. This review presents a bibliometric and patent analysis of MBL worldwide research trend based on the Scopus and World Intellectual Property Organization databases in 2013-2022. Based on the keywords related to MBL in the article title, abstract, and keywords, 592 research articles were retrieved for further analysis using various tools such as Microsoft Excel to determine the frequency analysis, VOSviewer for bibliometric networks visualization, and Harzing's Publish or Perish for citation metrics analysis. Standard bibliometric parameters were analysed to evaluate the field's research trend, such as the growth of publications, topographical distribution, top subject area, most relevant journal, top cited documents, most relevant authors, and keyword trend analysis. Within 10 years, MBL discovery has shown a steady and continuous growth of interest among the community of researchers. United States of America, China, and the United Kingdom are the top 3 countries contribute high productivity to the field. The patent analysis also shows several impactful filed patents, indicating the significance of development research on the structural and functional relationship of MBL for an effective structure-based drug design (SBDD). Developing new MBL inhibitors using SBDD could help address the research gap and provide new successful therapeutic options for treating MBL-producing bacterial infections.

    BACKGROUND: Plesiomonas shigelloides is a common pathogen in tropical regions, whereas it is rarely isolated in temperate climates. It is most often found in surface water and fish. During the last 10 years it was found to cause gastroenteritis 6 times in Ludwigshafen. Not all of these patients reported a trip to foreign countries.

    CASE REPORT: A 54-year-old male patient was hospitalized after a trip to Malaysia with strong greenish watery diarrhea and chills. On physical examination we saw a dehydrated patient in severely reduced general condition. The stool frequency was 30/d. The laboratory examinations only showed elevated parameters of inflammation. Plesiomonas shigelloides was cultivated in the stool cultures. With appropriate substitution of fluid and electrolytes, and antidiarrheal therapy the patient resumed a normal diet without any complications. Three days later his bowel movements were normal and his general condition was greatly improved. We withheld antibiotic therapy because of the noncomplicated course of illness.

    CONCLUSION: In Germany infections with Plesiomonas shigelloides are rare, an increase is observed because of increasing tourism to tropical regions. The course of infection is sometimes asymptomatic, but usually patients develop an acute gastroenteritis. Especially immunocompromised patients can show serious courses of infection. Plesiomonas shigelloides should be included in the differential diagnosis of acute gastroenteritis after journeys to tropical regions. Some of our patients, however, denied traveling to tropical regions. They also denied consuming seafood, which indicates a risk of infection in Germany. Still an infection with Plesiomonas shigelloides seems to be rare in northern European countries.

    A survey was conducted to determine the rate, outcome, and culture and sensitivity patterns of bacteraemic infections in a large Neonatal Intensive Care Unit (NICU). Over a nine-month period, 136 episodes of infection occurred in 132 (6.9%) out of 1926 admissions. Early onset infection accounted for 35 episodes (25.7%) and was associated with a higher mortality rate compared to late onset infection (45.7% vs 23.8%, p < 0.02). Very low birthweight (VLBW) infants had significantly higher rates of infection (19.4% vs 5.3%, p < 0.001) and mortality (45.2% vs 23.3%, p < 0.02) compared to bigger babies. Gram negative bacilli accounted for 25 early and 90 late isolates while gram positive organisms accounted for 10 early and 16 late isolates. The two main organisms (Acinetobacter and Klebsiella) showed a 69.0 to 85.3% resistance to aminoglycosides and 3rd generation cephalosporins. Ten of 13 isolates of Staphylococcus epidermidis and 3 of 4 Staphylococcus aureus were methicillin resistant. Multiply resistant infections were a major problem in this NICU and efforts to eradicate them needed to be intensified.

    Antimicrobial resistance is a global public health crisis. Antimicrobial Stewardship involves adopting systematic measures to optimize antimicrobial use, decrease unnecessary antimicrobial exposure and to decrease the emergence and spread of resistance. Low- and middle-income countries (LMICs) face a disproportionate burden of antimicrobial resistance and also face challenges related to resource availability. Although challenges exist, the World Health Organization has created a practical toolkit for developing Antimicrobial Stewardship Programs (ASPs) that will be summarized in this article.

    Candidacidal assay was used to assess the phagocytic and killing activities of polymorphonuclear leukocytes from paediatric patients diagnosed to manifest with characteristics of atopic dermatitis. From this group of patients evaluated, all the 11 cases exhibited lower candidacidal activity in comparison to the normal children. However, there were no abnormalities observed in the engulfing abilities and myeloperoxidase activities of these leukocytes. The result indicated that lower killing capacity of polymorphonuclear leukocytes in these patients may contribute to the frequent bacterial infections in atopic dermatitis children.
