  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..
