Mastitis inCamelus dromedarius in Saudi Arabia

Abstract

The correlation between camels' milk samples collected from abnormal inflamed udders and samples positive in the California Mastitis Test (CMT) was +0.803 (P less than 0.01). The bacterial count ranges of milk samples differed significantly (P less than 0.05) for those with a negative CMT and those with a positive CMT. Infection with many but not all bacterial species was associated with positive CMT results. The highest percentage of camel milk samples was included in the bacterial count range of 3.0 x 10(2) to 3.0 x 10(3) cfu/ml rather than in the greater than 3.0 x 10(3) cfu/ml range for most of the bacterial species. The most predominant bacterial isolates were Micrococcus spp., Staphylococcus aureus, Streptococcus spp. and Corynebacterium spp. followed by eight other flora. Chloramphenicol was the most effective antimicrobial agent of six tested against 118 bacterial isolates. Preliminary observations are made on chemotherapy of mastitis cases in camels.

Detection of subclinical mastitis in dromedary camels<br>(Camelus dromedaries) using somatic cell counts, california<br>mastitis test and udder pathogen

“…Gram-positive Cocci were the dominant udder pathogen isolated in our study, and regarded as important mastitis pathogens in camel (Barbour et al, 1985;Mostafa et al, 1987).…”

“…Very little is known about mastitis concerning their aetiology and occurrence in Camelidae (Abdel Gadir et al, 2006;Kalla et al, 2008). However, cases of mastitis in camel have recently been reported in Saudi Arabia (Barbour et al,1985), Egypt (Mostafa et al, 1987), Somalia (Abdurahman et al, 1991), Ethiopia (Bekele and Molla, 2001), Israel (Guliye et al, 2002) and Kenya (Matofari et al, 2003).…”

“…During the past decade there have been several reports on subclinical mastitis in dromedary camels (Obeid, 1983;Arush et al, 1984;Quandil and Oudar, 1984;Barbour et al,1985;Mostafa et al, 1987) and a few on Bactrian camels (Kospakov, 1976a,b); but little work has been done on subclinical mastitis and the udder's response to bacterial invasion. Barbour et al (1985) and Saber et al (2010) applied CMT to composite milk samples from the dromedary camels and concluded that the test was useful for screening subclinical infected udders.…”

“…Barbour et al (1985) and Saber et al (2010) applied CMT to composite milk samples from the dromedary camels and concluded that the test was useful for screening subclinical infected udders. Obeid (1983) found a good correlation between the milk leukocyte count and the 'rapid mastitis test'.…”

Antimicrobial susceptibility of bacterial species identified from mastitic milk samples of camel

“…The antimicrobial susceptibility of bacterial species to various drugs studied and recorded all over the world and many recommendations have been made by different workers on the susceptibility of organisms to various antibiotics. Barbour et al (1985) used the Muller Hinton agar for the susceptibility testing of 118 isolates by *Corresponding author. E-mail: mughal_161@yahoo.com.…”
