“…It is comparably higher than the incidence reported for camels in Egypt by Manal et al (2008). At the same cut off value ≥ 4mm, the present finding is lower than previously reported prevalence of 23.7% and 30.0% in Ethiopia (Kebede et al, 2008;Firdesa et al, 2012) and in India with 14.3% (Thakur et al, 2010). It is also lower than that of Abubakar et al (2014) for camels slaughtered at Kano abattoir, Nigeria.…”

A cross sectional abattoir based study was conducted from February 2014 to October, 2015 on camels slaughtered at Akaki municipality abattoir to determine the prevalence of Tuberculosis in camels and assess the association of risk factors with the prevalence of Tuberculosis in camels using single intra-dermal comparative cervical tuberculin (SICCT). Of the total of 387 camels investigated, overall camel tuberculosis prevalence of 9.82% (95% CI: 6.84%-12.8%) at a cut off value ≥ 4mm and prevalence of 17.05% (95% CI: 13.3%-20.82%) at a cut off value ≥ 2mm, were recorded. Pearson chi-square test reveals, there was statistically significant association of prevalence with the origin of camels at a cut off value ≥ 2mm (χ 2 = 13.461, P=0.000). However, there was no statistically significant association (P>0.05) of risk factors of age, sex, body condition and origin of camels with the prevalence at a cut off value ≥ 4mm.The multivariate logistic regression analysis shows at a cut off value ≥ 4mm, being old aged (adjusted OR= 0.999, 95% CI: 0.450-2.22), female (adjusted OR= 2.226, 95% CI: 0.5099-9.719) were identified as risk factors for positive tuberculin reactivity. Similarly, the multivariate analysis at a cut off value ≥ 2mm, showed being moderate body conditioned (adjusted OR= 1.583, 95% CI: 0.7399-3.385) was identified as risk factor for higher tuberculin reactivity. The present study aimed to determine tuberculin reactivity of camels and assess associated risk factors with the prevalence. It was concluded that Tuberculosis is an existing phenomenon in camels. It is therefore, recommended that detailed epidemiological investigations should be conducted for the better understanding of the epidemiology of the disease in camels of pastoral communities with particular emphasis to 24 Ethiop.

“…BrooksPollock et al [33] reported age-specific incidences with highest rates of infection in cattle aged between 12 and 36 months. Thakur et al [18] recorded higher incidence of BTB in cattle above 6 years age, whereas Moiane et al [34] recorded that animals older than 4 years are more likely to be infected and vulnerable to BTB compared to young ones. In the present study, although incidences of BTB in cattle of various age groups (1-5, 6-10, and 11-15 years) varied, there was no statistically significant difference among them.…”

“…Of 96 milk samples, two were positive for cultural isolation, whereas sediments from four milk samples were confirmed by 206 bp and 500 bp fragments in PCR assay for the presence of M. bovis. However, the reference strain [18] also reported higher positivity in JC and HFC breeds in Himachal Pradesh, India. The host genetics and its variation could be the reason for susceptibility to BTB in European breeds as reported by researchers [31].…”

“…In India, several workers have reported a high prevalence of BTB in organized farms. In a comparative study, Mukherjee [17] reported a prevalence of tuberculosis in two dairy herds at 15.76% (Northern India) and 0.65-1.85% (Western India), while Thakur et al [18] recorded 14.31% (overall animal prevalence) and 16.67% (farm prevalence) in Himachal Pradesh. In southern states of India such as Tamil Nadu and Karnataka, the rate of prevalence was 34.58% and 30-35%, respectively [19].…”

Aim: The aim of this study was to investigate the incidence of bovine tuberculosis (BTB), an old chronic disease having zoonotic potential, covering four districts in Gangetic delta region of West Bengal, India, and to find the prevalence in organized as well as backyard herds and variation in relation to their age, sex, and breeds. Methods:The incidence of BTB in exotic and indigenous breeds of cattle (n=173) of various age groups was investigated employing tuberculin (single intradermal tuberculin and comparative cervical tuberculin) tests and gamma interferon assay. Further, milk samples (n=96) from milching animals and antemortem (n=519) samples (nasal swab, buccal swab, and aspirates from pre-scapular lymph nodes) were also screened employing bacteriological and molecular techniques. Results:In total, 36 (25.4%) animals from organized and one (3.2%) from backyard farming sector were found positive to BTB. Polymerase chain reaction (PCR) of milk samples based on 16S rRNA amplified the 1030 bp band in four samples indicating them belonging to genus Mycobacterium. Species-specific primers used to differentiate between Mycobacterium bovis and M. tuberculosis confirmed the presence of M. bovis. Prevalence of BTB in exotic crossbred animals (34.6%) was significantly higher (p<0.001) compared to indigenous cattle (10.5%). Further, gender-wise analysis of data with respect to BTB revealed higher positivity (p<0.05) among cows/heifers (25.8%) compared to bulls/bullocks (7.3%). Although BTBpositive cattle were detected in all the age groups, no statistical difference (p=0.779) was found among them. Conclusion:The findings indicate a higher prevalence of BTB in exotic crossbred animals in Gangetic delta and variation in breed susceptibility, thereby suggesting an urgent review of the present policy on adopting national crossbreeding program and implementation of "One Health" approach.

“…There are limited reports available from India and many epidemiological and public health aspects of the infection remain largely unknown (Neeraja et al, 2014a;Neeraja et al, 2014b;Baqir et al, 2014;Verma et al, 2014b). An overall prevalence of bTB in India is 14.31 to 34.42% (Thakur et al, 2010). M. bovis mainly causes extra-pulmonary forms of tuberculosis and major route of transmission is the oral route.…”

India possess huge livestock population, which is endangered by different endemic infectious diseases (bacterial, viral, protozoan and parasitic), which collectively causes significant economic losses to the landless poor farming community. Infectious diseases impose economic losses by causing morbidity, mortality, decreased production (milk, meat, wool etc.), decreased feed conversion ratio which results in reduced weight gain, decreased draught power and fertility. Furthermore, economic burden is also due to the cost of treatment, abortion, consequences on internal livestock movement, germplasm and international trade. In addition, some of the diseases are zoonotic and inflicts considerable impact on public health. Uncertain agrarian climate, unpredictable weather, drought, floods, migration of livestock, scarcity of fodders, and unhygienic zoo-sanitary and healthcare practices together resulted in endemicity of diseases ultimately leads to more incidence and prevalence of livestock and poultry diseases throughout the year. Synchronized monitoring and surveillance of disease throughout the country is a fundamental requirement for sustainable livestock production. With fairly developed telecommunication in India, following technologies like interactive voice response system, SMS through mobile/cell phones and toll-free landline phones (voice mail) are required for enhancing the effectiveness and efficiency of
