The aim of this study was to evaluate the accuracy of cefoxitin disc diffusion as a prediction of oxacillin resistance in coagulase-negative staphylococci (CoNS), and also to compare genotypic and phenotypic methods for detecting this resistance property. A total of 151 clinical CoNS isolates were tested by PCR for the presence of the mecA gene (gold standard method). The isolate susceptibilities were determined by the disc diffusion method with oxacillin (1 microg) and cefoxitin (30 microg) and by the agar dilution method for cefoxitin and oxacillin. Although none of the techniques showed 100% sensitivity and 100% specificity, the cefoxitin disc diffusion and oxacillin agar dilution were the best methods for detecting resistance to oxacillin among CoNS as these methods produced the best negative and positive predictive values. A combination of methods can be used routinely to identify resistance to oxacillin in CoNS.

Introduction: Sepsis is a leading cause of morbidity and mortality in neonatal foals. Administration of appropriate antimicrobials and early aggressive supportive treatment is central to the efficacious treatment of neonatal sepsis and has proven to positively influence outcomes. The primary aim of our study was to evaluate microorganism results and antimicrobial sensitivities of neonatal foals with a positive blood culture submitted to our intensive care unit (ICU) during 2005-2022.

Cockroaches could play a role in the transmission dynamics of antimicrobial-resistant bacteria (ARB) at variable interfaces in Ugandan communities, acting as both reservoirs and vectors. This study investigated the burden and diversity of ARB carried by cockroaches in human settlements in Uganda, so as to understand their role in the spread of these pathogens and their potential as sentinels in antimicrobial resistance (AMR) surveillance programs. A retrospective analysis was conducted on two unpublished studies by Makerere University students.

Background: Antimicrobial resistance is increasing each year. For example, in 2019 it was directly responsible for an estimated >1 million deaths. Additionally, the development of new drugs is much slower, generating enormous concerns about responses to infection in the future health scenario.

With the passage of time there is enormous development in the field of science and technology, however, human health remained the utmost concern. There are different strategies that helps us to treat various diseases but they have adverse reactions on our bodies. Nanobiotechnology is the advanced field consisting of new techniques and fabrication procedures for nanostructures for making drugs more effective against diseases in less time.

Background: Neonatal sepsis (NNS) is a known cause of morbidity and mortality especially in developing countries. The global resistance scourge may worsen the management outcomes of NNS. This study aims to determine the current profile of bacteriological agents of NNS, their resistance status and associated mortality in our setting.
