Not AvailableSudden onset of diarrhea was observed in 10 (21.73%) neonatal camel calves aged between five to ten days in an organised camel farm. The feces of diarrheic calves were foul smelling, watery or pasty and pale yellow to greenish yellow coloured yellow to greenish yellow with occasional presence of flecks of fibrin and blood. The haematological parameters revealed no significant variations. The fecal culture from diarrheic calves on Mac Conkey and EMB agar revealed presence of Escherichia coli colonies which were further confirmed by uidA gene PCR and sequencing. The antimicrobial sensitivity test of all the ten isolates revealed high susceptibility for Ceftriaxone and Cefotaxime; intermediate susceptibility for Amoxicillin/Sulbactum, Gentamicin, Amikacin, Trimethoprim and Rifampicin; whereas resistance was recorded for Cloxacillin and Lincomycin. In addition six isolates also revealed resistance for Penicillin G, Amoxicillin, Enrofloxacin and Tetracycline. Our findings showed importance of role multidrug resistant E. coli in causing diarrhea in neonatal camels.Not Availabl

Not AvailableIn the present study, sudden mortalities were reported due to pneumonia in four neonatal camels (5 to 10 days old) of an organized dromedary camel farm. The clinicalmanifestations in affected camels were weakness, mild to high fever, not suckling, respiratory distress, and sudden death. On the basis of gross and histopathological lesions, the pneumonia was classified into bronchopneumonia (n = 2), bronchointerstitial pneumonia (n = 1), and interstitial pneumonia (n = 1). In bacterial culture, Klebsiella pneumoniae was isolated from lung of all the four cases. These bacteria were also confirmed by PCR from DNA isolated from culture as well as lung tissue. The sequencing of PCR products from four isolates of K. pneumoniae revealed homology with other pathogenic K. pneumoniae isolates from India and other countries. These findings confirmed the role of K. pneumoniae as an important etiological agent for causing pneumonia with sudden mortalities in suckling neonatal dromedary camels.Not Availabl

Not AvailableCamelpox is a wide-spread infectious viral disease of camelids. An outbreak of camelpox was reported in 15 adult male dromedary camels aged between 10 to 16 years of an organized herd in winter season. The infected camels showed clinical signs of fever, anorexia, lachrymation, pendulous lips, excessive salivation and pock lesions on the skin of head, neck, mouth, lips, extremities, thigh, abdomen, scrotum and inguinal region. Mortalities were recorded in three infected camels after 10–12 days of infection and showed systemic pox lesions characterized by vesicles, papules, ulcerations and raised pock lesions in the mucous membranes of the mouth, tongue, tracheal mucosa, lung, abomasum and liver. Histopathology study revealed characteristic pox lesions with intracytoplasmic eosinophilic inclusion bodies in tongue. Lung showed lesion of interstitial pneumonia (n ¼ 2) and bronchointerstitial pneumonia (n ¼ 1). Liver showed infiltration of mononuclear cells around central veins and degenerative changes of hepatocytes. The abomasum and intestine showed ulcerations, marked capillary congestion and areas of lymphocyte infiltration in mucosa and submucosa. The presence of camelpox virus (CMLV) was confirmed in viral DNA isolated from formalin fixed paraffin embedded (FFPE) tissues of tongue, lung, abomasum, liver, heart and intestine of infected camels by C18L gene PCR. The sequencing of viral DNAs showed phylogenetic relatedness with other CMLV isolates from India and other countries. Thus, our study confirmed the rare severe form of systemic camelpox outbreak in adult male dromedary camels hence future attention should be given for studies on virulence, strain identification and molecular epidemiology of CMLV for planning of effective preventive and control strategies.Not Availabl

Not AvailableThe present study investigated the pathological features of tuberculosis (TB) caused by Mycobacterium bovis and its diagnosis in naturally infected dromedary camels from an organized farm in India. During the period of the 5-year study, a total of 18 (19.56 %) camels out of 92 examined showed gross lesions compatible with TB at post-mortem. The clinical signs and pathological lesions in these camels were studied, and the efficacy of different diagnostic tests was also assessed. On the basis of occurrence and distribution of gross TB lesions, the infected camels revealed two different lesional patterns as pulmonary (n=15) and disseminated (n= 3) form. The histopathology of affected organs revealed typical granulomatous lesions wherein the giant cells and acidfast bacilli were occasionally observed in pulmonary form whereas they frequently observed in disseminated form. The single intradermal tuberculin test (SIDT) detected TB in 10 (55.55 %) whereas the Ziehl-Neelsen (ZN) stain and IS6110 PCR from tissue lesions detected 13 (72.22 %) and 18 (100 %) of the infected camels, respectively. The study suggests that pulmonary form of the TB is more common in camels indicating respiratory route as the major source of exposure in camel herds. Moreover, very low sensitivity of SIDT was observed which highlights the difficulty for confirmation of TB in live camels.Not Availabl

Not AvailableCamelpox caused by a Camelpox virus (CMLV) is a very important host specific viral disease of camel. It is highly contagious in nature and causes serious impact on health even mortality of camels and economic losses to the camel owners. It manifests itself either in the local/mild or generalized/severe form. Various outbreaks of different pathogenicity have been reported from camel dwelling areas of the world. CMLV has been characterized in embryonated chicken eggs with the production of characteristic pock lesions and in various cell lines with the capacity to induce giant cells. Being of Poxviridae family, CMLV employs various strategies to impede host immune system and facilitates its own pathogenesis. Both live and attenuated vaccine has been found effective against CMLV infection. The present review gives a comprehensive overview of camelpox disease with respect to its transmission, epidemiology, virion characteristics, viral life cycle, host interaction and its immune modulation.Not Availabl

Not AvailableCamelpox is an important viral disease of camels, which may produce mild skin lesions or severe systemic infections. Camelpox virus (CMLV) isolates retrieved from an incidence of camelpox in camels at Bikaner, India were characterized on the basis of genotype and pathotype. Histopathological examination of the CMLV scab revealed intracytoplasmic-eosinophilic inclusion bodies. The phylogenetic analysis of all eight CMLV isolates for C18L gene nucleotide sequence revealed its clustering with its strains M-96 from Kazakhstan and CMS from Iran. The study will help to understand the transmission chain, pathobiology, and epidemiology of circulating CMLV strains. The full genome sequencing of some of the exemplary samples of CMLV is recommended in order to plan and implement a suitable control strategy.Not Availabl
