Antimicrobial resistance pattern of methicillin-resistant isolated from sheep and humans in Veterinary Hospital Maiduguri, Nigeria.

Background And Aim: Methicillin-resistant (MRSA), an important opportunistic pathogen, is a Gram-positive coccus known to be resistant to β-lactam antibiotics. Its virulence depends on a large range of factors, mainly extracellular proteins, such as enzymes and exotoxins, that contribute to causing a wide range of diseases in human and animal species. The major reasons for the success of this pathogen are its great variability, which enables it to occur and thrive at different periods and places with diverse clonal types and antibiotic resistance patterns within regions and countries.

Phenotypic detection of methicillin-resistant aureus in village chickens from poultry markets in Maiduguri, Nigeria.

Objective: The study was carried out to detect the carriage of methicillin-resistant (MRSA) and their antimicrobial susceptibilities in village chickens sold at Maiduguri poultry markets using phenotypic characterization.

Materials And Methods: This was a cross-sectional study where 120 samples comprised 50% each of Nasal and cloacal swabs, were, respectively, collected from live village chickens sold at Maiduguri poultry markets and examined for the presence MRSA based on bacterial culture, biochemical characteristics, growth on oxacillin resistant screening agar base, and antimicrobial susceptibility tests.

Results: The study revealed an overall occurrence of 38.

Mycotoxins in poultry feed and feed ingredients in Nigeria.

Mycotoxins are toxic secondary fungal metabolites that can negatively affect animal productivity when ingested through feed. In order to assess mycotoxin contamination of poultry feed and feed ingredients vis-a-vis source tracking of feed contamination in Nigeria, 102 samples of feed (n = 30) and feed ingredients (n = 72) were collected from in-house mills of poultry farms across 12 states of Nigeria and analyzed for multiple mycotoxins using LC/MS-MS. One hundred and forty microbial metabolites were detected in the feed and feed ingredients.

Molecular detection of Nigerian field isolates of subsp. as causative agents of contagious bovine pleuropneumonia.

Contagious bovine pleuropneumonia (CBPP) is a highly contagious respiratory disease affecting cattle and is widely distributed in the sub-Saharan Africa. The objective of this study was to detect subspecies () the causative agent of CBPP from 90 cattle at slaughter using polymerase chain reaction-Restriction fragment length polymorphism. In this study, 450 samples suggestive of CBPP in Maiduguri, Yola and Gombe township abattoirs were processed according to standard protocols.
