Thermophilic Campylobacter spp. are important causative agents of diarrhoeal disease in humans. Antimicrobial-resistant Campylobacter spp. that originate from poultry can enter the human food chain and result in resistant Campylobacter spp. in human infections. Campylobacter spp. were isolated from chicken faeces collected from chicken farms near Harare. Human isolates of Campylobacter spp. wer...

Selected clinical isolates of Haemophilus influenzae were tested for their susceptibility to seven antibiotics by a microtiter broth dilution and an agar diffusion method. Eleven of 40 strains tested were resistant to ampicillin, the drug of choice, by both methods. All the strains tested were susceptible to chloramphenicol, and all but one were susceptible to tetracycline. Of the other four an...

OBJECTIVES Antimicrobial resistance of Helicobacter pylori endangers the successful eradication of the bacteria. The aim of this prospective surveillance study (ResiNet) is to continuously keep antimicrobial resistance of H. pylori in Germany under surveillance and to identify risk factors for its development. METHODS From July 2001 until December 2012, we tested the antimicrobial susceptibil...

Dried distiller’s grains (DG) produced from ethanol fermentations dosed with 0 (control), 2, or 20 mg/kg virginiamycin-based product or spiked with virginiamycin (VM) postfermentation were fed to cattle and effects on antimicrobial susceptibility, and prevalence of antimicrobial resistance genes in commensal bacteria was examined. Biological activity assays of DG (from each fermentation) indica...

Extended laboratory culture and antimicrobial susceptibility testing timelines hinder rapid species identification and susceptibility profiling of bacterial pathogens associated with bovine respiratory disease, the most prevalent cause of cattle mortality in the United States. Whole-genome sequencing offers a culture-independent alternative to current bacterial identification methods, but requi...

Susceptibility testing of Eikenella corrodens is usually performed by a Mueller-Hinton sheep blood agar dilution (AD) method. However, this method is impractical for testing only a few strains. We compared AD with the broth microdilution method using Haemophilus test medium (HTM) in order to determine the susceptibility of 36 clinical isolates of E. corrodens to eight antimicrobial agents. MICs...

The selection of an antimicrobial regimen is based on a number of factors, including the nature of the infection, the identity and susceptibility of the pathogens, host characteristics, and the pharmacokinetics and pharmacodynamics of antimicrobial agents. This article provides a comprehensive overview of these factors, with particular attention to pharmacokinetics and monitoring for efficacy a...

Rapid diagnostic microbiological techniques and antimicrobial susceptibility testing are necessary for early and adequate treatment. The utility of old (Gram stain, antigen detection, direct antimicrobial susceptibility testing, chromogenic media) and new techniques (molecular assays, MALDI-TOF) is summarized for the rapid diagnosis of bacteraemia and fungaemia, catheter-related bloodstream inf...

Antimicrobial activity of ethanolic extract Aloe vera were observed against Staphylococcus aureus, pyogenes, saprophyticus, Streptococcus pneumoniae and Escherichia coli, Pseudomonas aeruginosa, Klebsiella . leaf gel was used for extraction.Zones inhibition in millimeter to measure the antimicrobial effect. susceptibility test showed that has growth inhibitory effects tested pathogens. Ethanoli...
