Readiness for antimicrobial resistance (AMR) surveillance in Pakistan; a model for laboratory strengthening

Limited capacity of laboratories for antimicrobial susceptibility testing (AST) presents a critical diagnostic bottleneck in resource limited countries. This paper aims to identify such gaps and to explore whether laboratory networks could contribute towards improving AST in low resource settings. A self-assessment tool to assess antimicrobial susceptibility testing capacity was ...

Increase in isolation of extended spectrum beta lactamase producing multidrug resistant non typhoidal Salmonellae in Pakistan

Background Increasing resistance to quinolones and ceftriaxone in non typhoidal Salmonellae is a global concern. Resistance to quinolone and 3rd generation cephalosporin amongst non typhoidal Salmonellae (NTS) from Pakistan has been reported in this study. Methods Retrospective analysis of laboratory data was conducted (1990-2006). NTS were isolated and identified from clinical ...

Impact of infection control activities on the rate of needle stick injuries at a tertiary care hospital of Pakistan over a period of six years: an observational study

Background Accidental exposure to blood and body fluids is frequent among health care workers. They are at high risk of nosocomial transmission of blood borne pathogens due to injuries caused by used sharps. We are reporting impact of surveillance and educational program on the rate of needle stick injuries among health care workers at a tertiary care hospital in Pakistan. Methods ...

Rhinocladiella mackenziei as an Emerging Cause of Cerebral Phaeohyphomycosis in Pakistan: A Case Series

Six cases of Rhinocladiella mackenziei cerebral phaeohyphomycosis are being reported for the first time in Pakistan. Identification was confirmed by DNA sequencing (isolates and fixed tissue). Diabetes, head trauma, immunosuppressive treatment, and postpartum state were present in 4 cases. Two survivals and 3 fatalities occurred, with 1 patient lost to follow-up.

Evaluation of immune response to Hepatitis B vaccine in health care workers at a tertiary care hospital in Pakistan: an observational prospective study

Background Seroconversion rates reported after Hepatitis B virus (HBV) vaccination globally ranges from 85–90%. Health care workers (HCWs) are at high risk of acquiring HBV and non responders' rates after HBV vaccination were not reported previously in Pakistani HCWs. Therefore we evaluated immune response to HBV vaccine in HCWs at a tertiary care hospital in Karachi, Pakistan. ...
