Carbapenem resistant Acinetobacter has appeared an organism of uncertain resistivity towards antimicrobial agents. Among non-fermenting bacterium Acinetobacter is the second-most-commonly-isolated organisms in human. The fast intensify of their resistance to antibiotics, especially global emergence and extend of Acinetobacter strains resistant to carbapenem more restricted the therapeutic alternatives. The importation of A. baumannii and subsequent presence in hospitals has been well documented. In this study we evaluate the resistivity of Acinetobacter against carbapenem antibiotics at Jinnah University for Women, Karachi...

Infections caused by commensal organisms by changing to infectious life style generate much challenge to the current treatment strategies. Coagulase Negative Staphylococci (CoNS) are one of them, with their coexisting biofilm forming and multiple antibiotic resistance properties form important agents of nosocomial infection. To evaluate species distribution, biofilm formation, and antibiogram, CoNS isolates from various clinical samples were isolated. The presence of biofilm and associated genes icaAB, aap, atlE, embp, bhp, and fbe in CoNS was screened by PCR...

Epididymitis is one of the most frequent causes of acute scrotum during childhood. Unlike in adults, ascending bacterial infections are rarely the underlying cause of the condition in children. Antibacterial treatment in accordance with a prior antibiogram is possible in the presence of leukocyturia and significant bacteriuria. For the remaining cases, there are no definite criteria allowing for a decision on acute antibacterial treatment. The fact that antibacterial treatment is still initiated in cases of epididymitis in the clinical routine setting is based on the assumption of a possible infection rather than being based on facts...

BACKGROUND AND OBJECTIVES: Coagulase negative Staphylococcus (CoNS) is frequently isolated from blood cultures but their significance is difficult to interpret. CoNS bacteria which are often previously dismissed as culture contaminants are attracting greater importance as true pathogens in the past decades. Clinical evaluation of these isolates suggests that although there is a relative increase of CoNS associated bloodstream infections in recent years, the microorganisms still remain the most common contaminants in blood cultures...

Whole genome sequencing (WGS) makes it possible to determine the relatedness of bacterial isolates at high resolution, helping to characterise outbreaks. However, for Staphylococcus aureus, accumulation of within-host diversity during carriage might limit interpretation of sequencing data.In this study, we hypothesised the converse: that within-host diversity can in fact be exploited to reveal the involvement of long-term carriers (LTCs) in outbreaks. We analysed WGS data from 20 historical outbreaks, and applied phylogenetic methods to assess genetic relatedness and estimate time to most recent common ancestor (TMRCA)...
