Antimicrobial drug usage pattern in poultry farms in Nigeria: implications for food safety, public health and poultry disease management.

Good antimicrobial drug stewardship in food‑producing animals boosts productivity and limits transmission of zoonotic pathogens, but the imprudent usage is counterproductive. A nation‑wide survey to determine the pattern of antimicrobial drug usage in poultry was therefore conducted across 12 of the 36 States in Nigeria. The survey was conducted using structured questionnaire designed to elicit information on socio‑demographics, pattern of antimicrobial drug usage and awareness of the consequences of imprudent use of antimicrobials in food‑producing animals, among 2,402 randomly selected poultry farmers.

Antimicrobial Resistance and Virulence of Methicillin-Resistant from Human, Chicken and Environmental Samples within Live Bird Markets in Three Nigerian Cities.

Methicillin-resistant (MRSA) has emerged as a major threat to public health. This study investigated the occurrence of MRSA in humans, chickens, chicken meat and environmental samples within poultry farms and live bird markets in southwestern Nigeria. MRSA were isolated using selective culture and tested for antimicrobial susceptibility by broth microdilution.

Cultural, histochemical, and immunohistochemical detection of pathogenic species in the kidneys of cattle slaughtered in two abattoirs in Southwest Nigeria.

The impact of leptospirosis on food animals and humans has not been fully elucidated. This study was designed to determine the prevalence of pathogenic organism in renal tissues of slaughtered cattle from two major abattoirs in southwestern Nigeria. One hundred and seventy (170) kidney samples of different breeds, ages, and sexes were collected and examined using cultural isolation, microscopic agglutination test (MAT), Warthin silver (WSs) impregnation and immunohistochemistry (IH).
