Author(s): Umar*, Whong, Abdullahi and Aliyu
Staphylococcus species are considered the primary and most lethal agents that cause mastitis they are also an important
pathogens of public health concern because of their production of enterotoxins which causes staphylococcal food
poisoning. A total of 592 quarter milk samples, 30 bulk milk samples and 27 swab samples of milkers hands were
examined from 12 farms (both mechanized and small holder farms) in Kaduna as well as in Zaria. The prevalence
of subclinical mastitis from positive California Mastitis Test (CMT) (≥ +) was 24.5%. The mean Staphylococcal
count was 4.2 log10 cfu/ml. One hundred and three (103) Staphyloccocal isolates that were gram positive and
catalase positive were identified biochemically, out of which the identities of 51 was confirmed using the Microgen
Microbact Kit (MMK), from this number, 25 selected isolates were t.. View More»
