Background: Rotavirus B (RVB) causes diarrhea in humans and pigs. Although various RVB strains were identified in humans and various animals globally, little is known about the epidemiology RVB infection in Africa. In this study, we attempted to examine the prevalence of RVB infection in pig populations in Zambia.

Article Synopsis
  • Antimicrobial resistance (AMR) is increasing in Zambia's layer poultry sector, mainly due to improper use of antimicrobials, raising concerns about public health through potential contamination of food sources.
  • A study conducted in 2020-2021 collected 365 cloacal swabs from layer hens in Lusaka and Copperbelt provinces, finding a significant prevalence of resistant bacteria.
  • Results showed that 96.5% of the bacterial isolates had AMR, with a majority being multidrug-resistant, and highlighted the urgent need for improved antimicrobial management and monitoring in poultry farming.

Background: The food industry is increasingly becoming more scrutinized, given the frequency and intensity with which zoonotic diseases are being reported. Pathogen tracking has become more applicable with regards food safety. It is in this regard that the present study was formulated to track Listeria species.

A cross-sectional study was used to identify and assess prevalence and phenotypic antimicrobial resistance (AMR) profiles of and other enterobacteria isolated from healthy wildlife and livestock cohabiting at a 10,000 acres game ranch near Lusaka, Zambia. Purposive sampling was used to select wildlife and livestock based on similarities in behavior, grazing habits and close interactions with humans. Isolates ( = 66) from fecal samples collected between April and August 2018 ( = 84) were examined following modified protocols for bacteria isolation, biochemical identification, molecular detection, phylogenetic analysis, and antimicrobial susceptibility testing by disc diffusion method.

Whilst bovine leukemia virus (BLV) causes considerable economic losses to the dairy industry worldwide, information on its molecular epidemiology and economic impact in beef cattle is limited. Here, blood from 880 animals from Zambia's major cattle-rearing provinces was screened for BLV by nested PCR. Positive pools were sequenced and phylogenetically analyzed.

Bats are suspected to play important roles in the ecology of filoviruses, including ebolaviruses and marburgviruses. A cave-dwelling fruit bat, Rousettus aegyptiacus, has been shown to be a reservoir of marburgviruses. Using an enzyme-linked immunosorbent assay with the viral glycoprotein antigen, we detected immunoglobulin G antibodies specific to multiple filoviruses in 158 of 290 serum samples of R aegyptiacus bats captured in Zambia during the years 2014-2017.
