Abstract

To investigate Eschericiacoli infections in poultry flocks, 291 tissue samples from 237 necropsied carcasses submitted from ninety-nine (99) poultry flocks in north central Nigeria were analysed. These flocks comprised layer chicken, broiler, pullet, cockerel, turkey, quail, guinea fowl and ducks. Tissue samples were pre-enriched in 10 mL buffered peptone water media and aliquots were inoculated into selective enrichment broth, sub-cultured onEosin Methylene Blue (EMB) agar and MacConkey agar (MCA) and colonies of E. coli was examined based on cultural morphological characteristics. Layer poultry and laying quails exhibited reproductive lesions which correlates with history of disruption and reduction in egg production. Antibiotics resistance rate was significant (p <0.01) with macrolide and penicillin classes been the most resistant antibiotics in layers and broiler, while quinolones and aminoglycoside were most significantly susceptible (p <0.01). Multidrug resistance (MDR) was found in 56% of the E. coli isolates, with high prevalence in younger birds.

Abstract

This study was conducted to determine the pathological findings and molecular investigation of bacteria flora associated with the lesions in the lungs and livers of goats slaughtered for public consumption at the Ilorin, abattoir. A total of 450 samples (240 lungs and 210 livers) were collected and examined from goats slaughtered at the Ipata slaughterhouse in Ilorin, Kwara State. Of this number, 58 (24.17%; 95% CI = 19.19–29.96) lungs and 17 (8.10%; 95% CI = 5.17–12.58) livers revealed gross and microscopic pathological lesions as a result of bacterial pathogens. Based on gross examination, lung lesions were categorized into bronchopneumonia (27.59%), congestion (22.41%), interstitial pneumonia (17.24%), hemorrhages (13.77%), emphysematous (10.34%), and hyperemia (8.62%). In the liver, hepatic congestion 8 (47.06%) was the most observed gross lesion. Others included hepatic enlargement (29.41), hepatic fibrosis (17.65%), and hepatic abscess (5.88%). The molecular investigation revealed lung pathological lesions were as a result of Klebsiella species (51.72%) and Bacillus species (48.28%), while Escherichia species (52.94%) and Salmonella species (47.06%) were detected in the liver. The molecular analysis showed that the bacteria organisms detected in this study did not fully cluster with similar species from other parts of the world. The infection caused by these bacteria showed histopathological lesions in the lungs and livers. There is need for more studies to further characterize these bacteria species detected from Red Sokoto breeds of goats in-depth.

Abstract

Sixty large white breed piglets aged between 28 and 35 days were randomly assigned to five replicate groups (Bu1, Bu2, Bd1, Bd2, Bs1, Bs2, Lc1, Lc2, C1, and C2) with six pigs per group. The Bu1 and Bu2 groups were fed with wet and dry basal diets, respectively, supplemented with 0.8 mL (6 x 106 colony-forming units (CFU)) of Lactobacillus isolated from burukutu (beverage made from sorghum grains). The Pg1 and Pg2 groups were fed with wet and dry basal diets, respectively, supplemented with 0.8 mL (6 x 106 CFU/mL) of Lactobacillus isolated from pig hindguts. The Bs1 and Bs2 groups were fed with wet and dry basal diets supplemented with 0.8 mL (6 x 106 CFU/mL) of Bacillus subtilis and Bacillus pumilus, respectively. The Lc1 and Lc2 groups were fed with wet and dry basal diets supplemented with 0.8 mL (6 x 106 CFU/mL) of Lactobacillus acidophilus, respectively. Meanwhile, the C1 and C2 groups as the control groups were fed with wet and dry basal diets, respectively. The treatment and control animals were infected with Escherichia coli at 6 mL (1 x 1010 CFU/mL) orally. Aseptically collected fecal samples from the piglets in each group showed significant bacteriological and pathological differences. This study suggested that Lactobacillus species isolated from burukutu, pig hindguts, and industrial probiotics could inhibit colibacillosis.
