Pathogen group-specific risk factors for intra-mammary infection in water buffalo

A cross-sectional study was conducted to estimate the prevalence of intra-mammary infection (IMI) associated bacteria and to identify risk factors for pathogen group-specific IMI in water buffalo in Bangladesh. A California Mastitis Test (CMT) and bacteriological cultures were performed on 1,374 quarter milk samples collected from 763 water buffalo from 244 buffalo farms in nine districts in Bangladesh. Quarter, buffalo, and farm-related data were obtained through questionnaires and visual observations. A total of 618 quarter samples were found to be culture-positive. Non-aureus staphylococci were the predominant IMI-associated bacterial species, and Staphylococcus (S.) chromogenes, S. hyicus, and S. epidermidis were the most common bacteria found. The proportion of non-aureus staphylococci or Mammaliicoccus sciuri (NASM), S. aureus, and other bacterial species identified in the buffalo quarter samples varied between buffalo farms. Therefore, different management practices, buffalo bree..., The data was collected through a face-to-face interview with the farmer, and on-farm observations were taken. During the interview, the farmers gave information on the buffalo source, breed type, and frequency of milking per day. In contrast, animal information, such as body condition score (BCS), udder symmetry, udder shape, type of hand milking procedure, cleanliness of the hind quarter, and milking hygiene, was assessed through on-farm observations by the interviewer. Data analysis was done using R statistical software (version 4.1.2; R Foundation for Statistical Computing, Vienna, Austria). The prevalence of IMI in healthy (CMT = 1) or SCM quarter (CMT ≥ 2) samples was calculated by dividing the number of samples positive for each bacterial species (NASM; S. aureus; Streptococcus; Gram-negative; or other bacteria) by the total number of tested quarter milk samples. The exact binomial method was used to calculate the proportion's 95% confidence intervals. The prevalence of IMI-associ..., , # Pathogen group-specific risk factors for intra-mammary infection in water buffalo
