Patterns and persistency of fecal shedding of Klebsiella spp. by healthy adult dairy cattle were explored with probabilistic, statistical, and molecular methods. Fecal shedding was monitored longitudinally in 92 animals in 1 herd for 5 mo. Shedding patterns followed a random binomial distribution, and associations with host factors were not detected. For 12 animals from 4 herds, strain-typing o...

Title: In vitro antibacterial activity of piperacillin versus piperacillintazobactam on gram negative clinical isolates from a tertiary care hospital.Objective :To compare in-vitro antibacterial activity of piperacillin with piperacillin-tazobactam combination on the most common isolates of gram negative bacilli obtained from various clinical samples from a tertiary care hospital. Methodology :...

The use of contact lenses (CLs) has been widely associated with corneal alterations that range in symptomatology and severity. Lesions may vary from small peripheral sterile infiltrates to infectious central ulcers with sight-threatening potential. Contact lens wear has been described as the most important predisposing factor to microbial keratitis worldwide. Infections are more frequent in sof...

Background: Despite the medicinal importance of Balanites aegyptiaca (L.) Del, Stevia rebaudiana (Bert.) Bertoni, Tylophora indica (Burm.f.) Merrill and Cassia sophera (Linn.), the antimicrobial potential of these plants has not been explored extensively, especially those of Cassia sophera. Methods: Both aqueous and alcoholic extracts of various parts of respective plants, and their in vitro ra...

INTRODUCTION Antibiotic resistance in gram-negative bacilli is an area of increasing importance. This prospective study was performed to survey antibiotic resistance in Escherichia coli (E. coli), Klebsiella spp., Pseudomonas aeruginosa and Acinetobacter spp. over a 1-year period. MATERIALS AND METHODS Non-duplicate isolates of E. coli, Klebsiella spp., P. aeruginosa and Acinetobacter spp. we...

Mezlocillin is a new semisynthetic penicillin that inhibited 71% of the isolates of Serratia marcescens, 67% of Escherichia coli, 50% of Enterobacter spp., and 49% of Klebsiella spp. at a concentration of 12.5 mug/ml. It is also active against both indole-positive and -negative Proteus spp. and gram-positive cocci, except penicillin G-resistant Staphylococcus aureus. At a concentration of 100 m...

BACKGROUND Antimicrobial resistance is a serious problem that compromises the empirical treatment of infections, resulting in a lack of effective antibiotics and high medical expenses. Here, we aimed to monitor the trends in antimicrobial resistance among Enterobacteriaceae isolated from blood samples in mainland China. METHODS A total of 2240 Enterobacteriaceae isolates from blood were colle...

background bloodstream infection (bsi) is an important cause of mortality and morbidity and among the most common health-care associated infections. in this study we described the frequency of occurrence and antimicrobial susceptibility patterns of nosocomial and community-acquired bsi isolates from a teaching hospital in tehran, iran. patients and methods this cross-sectional study was conduct...

AIM To show the distribution and changes of causative agents of urinary tract infections in children and resistance rates by years and select the most appropriate antibiotics. MATERIAL AND METHODS In this study, the Başkent University Alanya Research and Application Hospital automation system microbiology recording book was screened retrospectively. Growth of a single microorganism above 105 ...

OBJECTIVE To review the aetiology and antibiotic resistance patterns of community-acquired sepsis in developing countries in infants where no clear focus of infection is clinically identified. To estimate the likely efficacy of WHO's recommended treatment for infant sepsis. DESIGN A systematic review of the literature describing the aetiology of community-acquired neonatal and infant sepsis i...
