“…Porcine cysticercosis is one of the most serious cestode zoonosis spreading worldwide, even in Muslim and Jewish communities where consumption of pork is prohibited (Schantz et al 1998;Singh et al 2010). The disease is caused by larval form of Taenia solium which is a two host cestode (Sing and Juyal 2013).…”

Porcine cysticercosis is an important medical and veterinary concern in the developing world. The present study was carried out to determine the morphological characteristics of Cysticercus cellulosae, so as to differentiate the C. viscerotropica (larval form of T. asiatica) which is having only rudimentary hooks on their rostellum. Morphological analysis was conducted on 22 Cysticercus positive samples. Measurements for number of hooks (large and small), the total length and blade length of large and small hooks per rostellum were carried out as per previous studies. Microscopic examination of all the cysts showed typical characteristic of T. solium i.e. presence of hooks in all the cysts. The results indicated absence of T. asiatica from naturally infected pigs in Punjab (India).

“…Poor hygiene, overcrowding, lack of veterinary attention and zoonotic awareness in developing countries such as India further exacerbates the risks of transmission of disease (Schantz, 1991;Singh et al, 2011). In India, the hydatid cysts are found in most of the food producing animals (cattle, buffalo, sheep, goat and pigs) and humans; the disease in intermediate hosts occurs throughout the country at varying rates (Singh et al, 2010;2012;Pednekar et al, 2009). The significant increase (p<0.001) in sero positivity during a five year period (23.12 %, 1999 -2003) as compared with previous years (10.97 %, 1984 -1998), and a similar increase (p<0.001) in positive Casoni's test (33.83 %, 1999 -2003 versus 21.38 %, 1984 -1998) has been reported for human cystic echinococcosis in northern India (Khurana et al, 2007).…”

Echinococcosis is a preventable but neglected zoonosis in India. Although the disease in domestic animals is usually asymptomatic, huge economic losses have been reported due to cystic echinococcosis in livestock in India. The molecular characterization of Echinococcus from dog populations has not been previously carried out in Punjab (India). A total of 237 pet and stray dog faecal samples were collected and examined for the presence of eggs of the Taeniidae family in Punjab (India). A 255 base pair fragment of the mitochondrial 12S rRNA gene was amplified and the presence of sheep strain (G1) of E. granulosus has been reported. We detected eggs of the Taeniidae family in 2.11 per cent of the faecal samples. High prevalence was recorded in stray dogs (9.52 %) living near slaughter shops/post mortem areas. The prevalence of E. granulosus sheep strain (G1) using PCR was found to be 0.84 per cent in naturally infected dogs. This is the first study confirming the presence of E. granulosus (G1) sheep strain in dogs in Punjab (India). The results reveal the presence of sheep strain of E. granulosus and demand implementation of Animal Birth Control programme so as to control the stray dog population of the country.

Toxocara canis, Trichinella spiralis and Taenia solium helminthozoonoses: seroprevalence among selected populations in north India

2013

Helminthozoonoses are being considered as a research priority in India and many other tropical and subtropical countries. Taenia solium and Trichinella spiralis are emerging public health and food safety issues in the country and the developing world. The asymptomatic Ta. solium carriers act as important risk for neurocysticercosis, leading to adult onset epilepsy in the country. Human toxocariasis is another common zoonosis which occurs due to larvae of Toxocara canis or T. cati. The current study was planned to obtain baseline seropositivity data for Ta. solium, To. canis and Tr. spiralis antibodies among selected populations in Punjab province of northern India. In the present study, 122 human subjects belonging to selected occupations viz. farmers and veterinary practitioners were screened using the RIDASCREEN Ò Ta. solium IgG, RIDASCREEN Ò Toxocara IgG and RIDA-SCREEN Ò Trichinella IgG enzyme immunoassays for the qualitative determination of IgG antibodies against Ta. solium, Tr. spiralis and To. canis, respectively in human serum. The seropositivity of To. canis, Tr. spiralis and Ta. solium infections were found to be 22.13, 5.73 and 11.47 %, respectively in human serum samples. The relative risk of being infected for To. canis, Tr. spiralis and Ta. solium infections was found to be 1.91 (95 % CI 0.786-4.669), 2.61 (95 % CI 0.3258-20.94) and ) times high respectively in farmers when compared to veterinary practitioners. The present study indicates that exposure to To. canis and Ta. solium is not uncommon among farmers and veterinary practitioners in this part of the country. These results provided evidence of Tr. spiralis among selected human populations in the country and demand more research related to trichinellosis in their respective animal and human hosts.
