Mastitis incidence and bacterial causative agents isolated from lactating she-camel (Camelus dromedaries).

Abstract

This study was carried out to determine the incidence of mastitis in lactating she-camel in North Kordofan State, Sudan. Furthermore, the causative bacterial agents were identified. Sixty lactating she-camels were examined clinically for mastitis. Thereafter milk samples (n= 216 samples) were collected from each quarter of the udders of the she-camels. The samples were subjected to white side test (WST), somatic cell count test (SCC) and bacteriological examination. The results of the clinical examination revealed that the incidence of mastitis was 25% (n=15 she-camels) while upon the WST and SCC were15% (n= 9 she-camels) and 13.33% (n= 8 she-camels), respectively. However, the incidence of mastitis (41.66%) was significantly high (p<0.001) when the milk samples were bacteriological examined (n=25 she-camel).The bacterial examination revealed that the predominant cause is Staphylococcus spp. (80.30%) followed by Bacillus spp. (9.09%), Pasteurella spp. (6.06%), Corynebacteria spp. (3.03%), and Streptococcus spp. (1.52). It is concluded that the mastitis prevails in lactating she-camels in North Kordofan State and the most predominant cause of mastitis are Staphylococcus species. Mastitis emerges as a serious hazard and problem that affect a resource essential for many nomadic tribes that lives in the desert and semi desert areas. A national program to diagnose and compact this disease should be launched.

Subclinical mastitis in dairy camels in Algeria: Comparison of screening tests

“…The present study showed that the good combination of sensitivity and specificity of these tests was obtained with a thresholds of 240000 cell/ml and score trace of CMT was considered as positive, respectively. This finding is supported by the report of Alamin et al (2013) who suggested that a threshold of SCC more than 2.5 × 105 cells/ml can be considered as indication of udder infection in camel. Sensitivity of CMT observed in our study was lower than that reported by Younan et al (2001) which revealed a rate ranging from 68 %-77 % for major pathogen (S. agalactiae and S. aureus) in camel and that observed by Sharma et al (2010) in cattle.…”

“…In addition, previous reports have confirmed that milk SCC can be used as a screening test to detect subclinical mastitis in camels (Bekele and Molla, 2001;Saleh and Faye, 2011). However, Alamin et al (2013) reported that the SCC couldn't be used for detection of subclinical mastitis in camel.…”

“…Many reports revealed that lactating camel can get mastitis easily (Abdel Gadir et al, 2006;Alamin et al, 2013;Al-Juboori et al, 2013), especially in its subclinical form (Hawari and Hassawi, 2008;Ahmed et al, 2011;Alamin et al, 2013;Husein et al 2013). Subclinical mastitis causes suffering of the animal, reduces milk yield, alters milk properties, impairs preservation and processing and represents a public health concern for consumers of camel milk (Tibary and Anouassi, 2000;Saleh and Faye, 2011).…”

“…Different methods have been suggested for detection of subclinical mastitis in camels, such as somatic cell count (SCC), California mastitis test (CMT) (Saleh and Faye 2011;Alamin et al, 2013;Ali et al, 2016), electrical conductivity (Eberlein, 2007;Ali et al, 2016) and pH estimation (Tuteja et al 2003;Ali et al, 2016).…”

Camel Mastitis: A Review

“…Camel mastitis has been estimated to affect more than 25% of lactating she-camel [7,8]. It is also known to cause approximately 70% losses in milk production [9].…”
