Background: The Global Enteric Multicenter Study (GEMS) determined the etiologic agents of moderate-to-severe diarrhea (MSD) in children under 5 years old in Africa and Asia. Here, we describe the prevalence and antimicrobial susceptibility of non-typhoidal Salmonella (NTS) serovars in GEMS and examine the phylogenetics of Salmonella Typhimurium ST313 isolates.
Methods: Salmonella isolated from children with MSD or diarrhea-free controls were identified by classical clinical microbiology and serotyped using antisera and/or whole genome sequence data. We evaluated antimicrobial susceptibility using the Kirby-Bauer disk diffusion method. Salmonella Typhimurium sequence types were determined using multi-locus sequence typing and whole genome sequencing was performed …

Bacterobilia In Acute Cholecystitis: Bile Cultures' Isolates, Antibiotic Sensitivities And Antibiotic Usage. A Study On A Pakistani Population., Yousaf Bashir Hadi,, Muhammad Waqas, Hafiz Muhammad Umer,, Ammar Alam, Abdul Rehman Alvi, Muhammad Rizwan Khan

Department of Surgery

Abstract

Acute cholecystitis is one of the most common acute surgical conditions. Laparoscopic cholecystectomy remains the mainstay of treatment. In patients managed non-operatively, antibiotics play an important role in the treatment of cholecystitis. The current retrospective observational study was conducted at a tertiary care hospital in Karachi, and comprised medical records of patients admitted between 2008 and 2014with acute cholecystitis and in whom bile cultures were obtained. Of the 509 patients with a mean age of 51.15 ± 13.4years, early laparoscopic cholecystectomy (within 72hours) was performed on 473(92.9%) cases, while the rest underwent percutaneous cholecystostomy. Bile cultureswere positive in 171(33.6%) …

Low Prevalence Of Methicillin Resistant As Determined By An Automated Identification System In Two Private Hospitals In Nairobi, Kenya: A Cross Sectional Study, Geoffrey Omuse, Beatrice Kabera, Gunturu Revathi

Pathology, East Africa

Background: Staphylococcus aureus (S.aureus) is a major cause of both healthcare and community acquired infections. In developing countries, manual phenotypic tests are the mainstay for the identification of staphylococci with the tube and slide coagulase tests being relied upon as confirmatory tests for S. aureus. The subjectivity associated with interpretation of these tests may result in misidentification of coagulase negative staphylococci as S.aureus. Given that antibiotic resistance is more prevalent in CONS, this may result in over estimation of methicillin resistant S.aureus (MRSA) prevalence.

Methods: A review of susceptibility data from all non-duplicate S.aureus isolates generated between March 2011 and …

Antibiotic Susceptibility Patterns Of Helicobacter Pylori And Triple Therapy In A High-Prevalence Area, Javed Yakoob, Shahab Abid, Z. Abbas, S. N. W. Jafri

Department of Medicine

This study aims to determine primary Helicobacter pylori resistance and its effect on eradication of the organism. Ninety-two Patients with dyspeptic symptoms were enrolled. H. pylori was cultured and antibiotic sensitivity was determined by the Epsilometer test (Etest) for clarithromycin (CLR), amoxicillin (AMX) and metronidazole (MTR). 23S ribosomal RNA (rRNA) point mutations associated with clarithromycin resistance were also detected. Patients were treated with omeprazole (40 mg daily), CLR (500 mg) and AMX (1g twice a day) for 14 days. A (14)C-urea breath test ((14)C-UBT) was repeated four weeks after completion of treatment to confirm eradication. Triple therapy failure was seen …

Antibiotic Susceptibility Of Pathogens Isolated From Patients With Community-Acquired Respiratory Tract Infections In Pakistan--The Active Study, Afia Zafar, Zahid Hussain, Eale Lomama, Sophie Sibille, Seema Irfan, Erum Khan

Department of Pathology and Laboratory Medicine

BACKGROUND: Respiratory tract infections (RTIs) are amongst the most wide spread and serious infections, accounting for over 50 million deaths globally each year. In developing countries, infants under 4 years of age are at greatest risk of lower RTIs, whereas in developed countries the severity of infection and rate of mortality are greater in elderly. The objective of the survey was to determine the in vitro susceptibility of antibiotics commonly prescribed RTIs against Streptococcus pneumoniae (SP), Haemophilus influenzae (HI) and Streptococcus pyogenes, isolated from patients with community-acquired RTIs globally. This survey involved 9 countries. In this study we present the …
