Abstract

This research was carried on 80 quarter out of 600 quarter milk samples collected aseptically from 150 apparently healthy cows in 4 private farms at Alexandria Governorate (Abees – Ameria- Borg-El-Arab and Mariout ) and prove the affection of subclinical mastitis  by use California mastitis  test. The total incidence of subclinical mastitis in Alexandria Governorate was 13.33% .While the incidence in 4 farms (Abees – Ameria- Borg-El-Arab and Mariout ) were ( 14.3 %, 13.9% , 12.5%, and 10% ) respectively. The number of the bacterial isolates in these investigation was 92 isolates, while the number and frequency percentages of the isolates were Staphylococcus aureus 23 (25%), Streptococcus agalactia 20 (21.37%), Streptococcus dysagalactia  8 isolates (8.69%), E-coli 8  (8.69%), Arctenobacterium bovis 18 (19.26%), Pseudomonas aeruginosa  13 (14.13%), and Pseudomonas fluorescens 2 isolates (2.17%). Also, the sensitivity of the isolated organisms to antibiotics were discussed. It was found that most of the isolated species were highly sensitive to Chloramphenicol, Gentamycin and Cephaloxin and less sensitive to Tetracyclin and Streptomycin but were resistance to Penicillin and Amoxicillin. Public health significance was discussed.
