Diagnostic study of she camel subclinical mastitis in Al-hyadia district – Al-Najaf province

Abstract

This study was carried out at Al- Hyadia arid area / Al- Najaf on 82 she camels. According to bacterial isolation, the subclinical mastitis was detected in 24 out of 82 she camels at percentage rate 19.68%. The highest percentages of isolates were 17.68 and 12.92 for Coagulase –ve staphylococci followed by Streptococcus spp. respectively. While the percentages rate of Staphylococcus aureus, E. coli and Micrococcus spp were 10.2%, 8.16% and 4.08% respectively. Based to bacterial isolation as confirmed diagnosis of subclinical mastitis, the milk samples with Coagulase –ve staphylococci, E. coli and Staphylococcus aureus revealed score 3 to California mastitis test (CMT) reaction with PH ranged 7.5-6.73 and electric conductivity 8.1-7.9 ms/cm while in Streptococcus spp. and Micrococcus revealed score 2 to CMT reaction with PH ranged 6.89-6.44 and electric conductivity 7.81-7.68 ms/cm. In conclusion the results of the present study approved investigation of subclinical mastitis in She camel and its causative agents. Moreover, California mastitis test was approved as fast and effective but less sensitive in diagnosis of subclinical mastitis.
