Assessment of Microbial Load and Multidrug-Resistant Profile of Bacterial Flora from Cattle in Bauchi, Nigeria

Aim: The study aimed to assess the bacterial load of in rectal swabs from cattle by isolating Enterococcus spp and Escherichia coli, and determining the multidrug-resistant pattern of the isolates. Study Design: The study is a clinical-veterinary laboratory investigation involving the isolation and determination of the multidrug-resistant (MDR) profile of Enterococcus spp and E. coli isolated from cattle rectal. Place and Duration of Study: This study was carried out in the Yelwa and Gubi campuses Farm centers of Abubakar Tafawa Balewa University (ATBU), Bauchi, Nigeria, in period extended from April to June 2021. Methodology: Fresh rectal swab samples were collected from the randomly selected cattle and labeled. The samples were immediately transported and processed in the Microbiology laboratory at Yelwa Campus, and the bacterial load of each sample was determined using standard techniques. Enterococcus spp and E. coli were isolated using differential culture media followed by an appropriate biochemical identification test. The isolates were subjected to the Kirby-Bauer disc diffusion method, to assess the antimicrobial susceptibility pattern. Results: In Yelwa, the highest microbial load is 2.7 x 1012 CFU/g. while the lowest microbial load is 2.0 x 1012 CFU/g. In the Gubi campus, the highest microbial load is 3.4 x 1012 CFU/g. while the lowest microbial load is 2.7 x 1012 CFU/g. Both in Yelwa and Gubi ,the result showed that most isolates of Enterococcus spp and E. coli are multidrug-resistant. In Yalwa some of the isolates showed 100% resistance against Norfloxacin, Rifampicin, Ampicillin, and Streptomycin, while Gentamycin gave the lowest multidrug resistance (57.4%). In Gubi, the highest was to ampicillin with (90.6%) frequency, while the lowest resistance was found in Chloramphenicol (11.3%). In Yelwa, a high percentage resistance (92.6%) was observed in Streptomycin, and Cephalexin has the lowest (20.4%). In Gubi, all the E. coli isolates had 100% resistance against sulfamethoxazole, and the lowest was in Ofloxacin (43.4%). Conclusion: This study found that cattle in the area are reservoirs of bacteria that are both part of the normal flora and opportunistic pathogens, and harbored resistance phenotypes. It is therefore advocated that the use of these animals’ faeces as manure should be done with caution, particularly after pre-treatments.

Evaluation of bioherbicidal potential of Carica papaya leaves / Avaliação do potencial de bioherbicida dase folhas de Carica papaya

Abstract Due to increased number of herbicide resistant weeds, it is needed to explore the allelopathic potential of plants as an alternative. The research was conducted to investigate allelopathic effects of Carica papaya L. leaf powder and aqueous extract on seeds as well as pre-germinated seeds of Avena fatua L., Helianthus annuus L., Rumex dentatus L., Zea mays L. and Triticum aestivum L. on filter paper and soil in Weed Management Program Laboratory, Department of Plant and Environmental Protection at PARC Institute of Advanced Studies in Agriculture, National Agriculture Research Centre, Islamabad, Pakistan. Germination percentage (%), radicle length (cm) and plumule length (cm) were parameters observed for 'Plant leaf powder bioassay' and 'Aqueous extract method'. Most significant growth inhibition was observed in A. fatua seedlings in filter paper method. A. fatua radicle length was reduced by C. papaya aqueous extract (80%) and leaf powder (89%) bioassays. Plumule length was reduced under the influence of aqueous extract (57-73%) and powdered material (59-77%). The inhibitory effects on other test species were in sequence of H. annuus followed by Z. mays and R. dentatus. The aqueous extract showed non-significant effect on wheat seed germination, radicle and plumule growth. It is suggested that C. papaya aqueous extract can be used as source of weed management in wheat crop.

Resumo Devido ao aumento do número de ervas daninhas resistentes aos herbicidas, é necessário explorar o potencial alelopático das plantas como uma alternativa. A pesquisa foi conduzida com o objetivo de investigar os efeitos alelopáticos do pó foliar de Carica papaya e do extrato aquoso das sementes, bem como das sementes pré-germinadas de Avena fatua, Helianthus annuus, Rumex dentatus, Zea mays e Triticum aestivum em papel de filtro e solo no Laboratório do Programa de Manejo de Ervas Daninhas, Departamento de Plantas e Proteção Ambiental do Instituto PARC de Estudos Avançados em Agricultura, Centro Nacional de Pesquisa Agrícola, Islamabad, Paquistão. A porcentagem de germinação (%), o comprimento radicular e o comprimento da plúmula (cm) foram os parâmetros observados para o 'Bioensaio de Pó de Folha de Planta' e o 'Método de Extração Aquoso'. A maior inibição do crescimento foi observada em mudas de A. fatua no método de papel de filtro. O comprimento radicular de A. fatua foi reduzido com os extratos aquosos de C. papaya (80%) e pó de folhas (89%). O comprimento das plúmulas foi reduzido sob a influência do extrato aquoso (57-73%) e material em pó (59-77%). Os efeitos inibitórios em outras espécies-teste foram na sequência de H. annuus seguido por Z. mays e R. dentatus. O extrato aquoso apresentou efeito não significativo na germinação das sementes de trigo, nos crescimentos radiculares e das plúmulas. Sugere-se que o extrato aquoso de C. papaya pode ser utilizado como fonte de manejo de plantas daninhas na cultura do trigo.
