| Sumario: | The purpose of this study was to evaluate the ultrasound and histopathological findings in comparison with the bacteriological examination to help in prognosis decision for udder alteration occurred by different cause and forms of mastitis. 40 Egyptian Baladi female goats (does) were examined for detection of mastitis during lactation period by clinical and laboratory examination include inspection, CMT, ultrasonography, pathological and bacteriology examination accompanied with antimicrobial susceptibility for isolated microorganisms (M.O.) for detection of udder alterations due to mastitis The results revealed the prevalence of subclinical and clinical mastitis was 25% and 12.5% respectively. 30% of the isolates were coagulase-negative Staph. (CNS), while S. aureus and Strep. Spp. were 25% for each and E.coli represent 10% in subclinical milk samples, although these M.O. represented 40%, 30%,10% and 0% respectively in clinical milk samples. Ultrasonography of the parenchyma of healthy mammary gland appeared as a homogenous structure of average echogenicity filled with anechogenic content (milk). In contrast, the characteristic changes that occurred during all different mastitis phases in the mammary glandular parenchyma, teat and the milk appeared with different echogenicity. Histopathological features of tissue samples obtained by surgical biopsy technique described some different characteristic features of chronic, diffused interstitial mastitis lesions compatible with a longstanding subclinical infection. All forms of mastitis require microbiological confirmation for definitive diagnosis. Ultrasonography and histopathology give a clear prognosis for the status of the udder to minimize the impact of it. |
