Abstract
In this study we collected 205 mastitic milk samples from dairy farm and random field samples in Menofia governates for
investigation the most prevalent causes of mastitis. The reported
results from this survey revealed that Staphylococcus. aureus was
most isolated pathogens as it founded 37 isolates (19.5%) and all
Streptococcus species 39 isolates (21.95%), E.coli 33 (17.4%),
fungi 30 isolates (14.34%), and mixed bacterial infection 51 isolates
(26.9%). The Streptococcus species including S.agalactia 18
isolates (9.5%), S.dysglactia 13 isolates (6.8%), and S.ubris 8
isolates (4.2%), from total isolates founded. While mixed bacterial
infections including Staphylococcus aureus & E.coli 22 isolates
(11.6%), Staphylococcus aureue & Streptococcus agalactia 15
isolates (7.9%), Streptococcus uberis & E.coli 14 isolates (7.4%).
While fungus isolates from cases of clinical mastitis only that not
response to treatment by antibiotics and the isolates including
Candid albicans 8 isolates (4.2%), Candida. Tropicalis 3 isolates
(1.6%), Asperagillus fumigatus 10 isolates (5.26%), and Aspergillus
flavus 9 isolates (4.7%), form all mastitic isolates we were founded.
We found that there was a relationship between somatic cell
count and mastitis incidence as high somatic cell count appear in
subclinical mastitis ranged from 200,000 – 500,000 cell/ml of milk
and very highly somatic cell count in clinical mastitis cases ranged
from 500,000 – 2,000,000 cell/ ml of milk, so somatic cell count
can be used as indicators for detection of subclinical mastitis.
