Genetic Detection of Some Bacterial Species Associated with Bovine Keratoconjunctivitis Infections in Basra Governorate

Abstract

Veterinary chemicals are pharmaceuticals or treatments that are used in cattle to treat or prevent disease, injury, and pests. Livestock survival and productivity would be severely reduced without veterinary drugs, especially for intensively maintained animals like pigs and poultry. Infectious bovine keratoconjunctivitis is a bacterial eye illness of cattle, and there is limited knowledge on the study of bacterium pathogen-contaminated eyes of animals in Basra province. As a result, the purpose of this research was to isolate and classify some bacterial species associated with infection in cattle with keratoconjunctivitis. This study included examination of 120 eye swabs from cows from different regions in the Basra governorate. The current study was carried out from October 2018 to February 2019. Out of 120 cases involved in this study, 30 cases were identified to have keratoconjunctivitis. The results of the study showed that eye infections in cows were mostly unilateral, in one eye (69%), and less than bilateral infections in both eyes (30.9%). Twenty different bacterial isolates were obtained, and the isolated bacteria were identified genetically by 16S rDNA and sequencing as Escherichia coli 40%, Bacillus subtilis 10%, Enterobacter cancer genus 10%, Enterobacter hormaechei 10%, Enterobacter cloacae 15%, and Klebsiella pneumonia 15%.
