“…So far, fifteen serotypes 9,10,12,(16)(17)(18)21,23,and 24) were identified by VI, while 22 serotypes 23,and 24) were reported by serological testing (Prasad et al 1992;Sreenivasulu et al 2004;Joardar et al 2009;Chauhan et al 2014;Ranjan et al 2015;Krishnajyothi et al 2016;Rao et al 2016;Hemadri et al 2017). In several states of India, BTV antibodies were detected in goat, cattle, camel, buffalo and mithun; however, clinical disease was not frequently reported in these species (Joardar et al 2015;Maan et al 2017;Shah et al 2017;Karam et al 2018).…”

Bluetongue (BT) is an economically important, non-contagious viral disease of domestic and wild ruminants. BT is caused by BT virus (BTV) and it belongs to the genus Orbivirus and family Reoviridae. BTV is transmitted by Culicoides midges and causes clinical disease in sheep, white-tailed deer, pronghorn antelope, bighorn sheep, and subclinical manifestation in cattle, goats and camelids. BT is a World Organization for Animal Health (OIE) listed multispecies disease and causes great socio-economic losses. To date, 28 serotypes of BTV have been reported worldwide and 23 serotypes have been reported from India. Transplacental transmission (TPT) and fetal abnormalities in ruminants had been reported with cell culture adopted live-attenuated vaccine strains of BTV. However, emergence of BTV-8 in Europe during 2006, confirmed TPT of wild-type/field strains of BTV. Diagnosis of BT is more important for control of disease and to ensure BTV-free trade of animals and their products. Reverse transcription polymerase chain reaction, agar gel immunodiffusion assay and competitive enzyme-linked immunosorbent assay are found to be sensitive and OIE recommended tests for diagnosis of BTV for international trade. Control measures include mass vaccination (most effective method), serological and entomological surveillance, forming restriction zones and sentinel programs. Major hindrances with control of BT in India are the presence of multiple BTV serotypes, high density of ruminant and vector populations. A pentavalent inactivated, adjuvanted vaccine is administered currently in India to control BT. Recombinant vaccines with DIVA strategies are urgently needed to combat this disease. This review is the first to summarise the seroprevalence of BTV in India for 40 years, economic impact and pathobiology.

Bluetongue (BT) is a non-contagous arthorpbpd-born viral infection transmitted by insects, particularly biting midges of the Culicoides species, and can affect wild and domestic ruminants, including sheep, goats,cattels, deer, elk, and camales. This study aims to determine the prevalence of BTV antibodies in camels reared in central Sudan and the potential risk factors contributing to its epidemiology. A total of 184 blood samples were collected between November 2014 and May 2015 from six localities in Khartoum state in Sudan using multi-stage random sampling. The sampled farms' characteristics and management factors were obtained using a semi-structured questionnaire. Serology for BTV antibody detection was performed using a competitive enzyme-linked immunosorbent assay (cELISA). Our findings indicated a high prevalence of circulating BTV. antibodies in camels' sera (66.8%, 95% CI = 0.6–0.73). Camels raised on farms were more likely to contract the disease (OR = 0.424, CI = 0.223–1.071, p-value = 0.040) than camels bought from the market or other farms. The presence of other animals in the camels' herds, such as sheep, goats, and cattle, has increased the risk of infection with diseases compared to camels that are reared alone in the farms (OR = 0.176, CI = 0.43–0.771, p-value = 0.016). The high BTV seroprevalence indicates the endemicity of BTV, the risk of previous exposure, and the potentiality for BTV Transmission among asymptomatic camels. Control measurements, including vector control, trade restriction, and vaccination, are recommended to protect vulnerable animal species from BTV infection.
