“…The prevalence of 14.3% (n = 300) obtained in this study is high compared to those reported elsewhere; 9.6%, 2.4%, and 1.3% reported in Jos [11], Togo, and Benin, respectively [15], but closer to the 16.3% (n = 544) reported in Mbulu community, Tanzania [16]. Other studies using similar antibody detecting techniques have reported prevalence of 7.4% in South Africa and 20.5% in Mozambique [6].…”

Introduction: Taenia solium cysticercosis is considered an emerging parasitic zoonosis of global importance due to its impact on both agriculture and public health in developing countries. Epidemiological information on human cysticercosis is limited in Nigeria. This study was conducted to determine the seroprevalence of human cysticercosis in areas of Kaduna metropolis, Nigeria, where small-holder pig farming is practiced. Methodology: A cross-sectional survey was conducted in Kaduna South and Chikun Local Government Areas of Kaduna metropolis, which are widely involved in small-holder pig farming and pork consumption. A total of 300 human sera were collected and tested for the presence of IgG antibodies to T. solium using an enzyme-linked immunosorbent assay (ELISA) technique. A structured questionnaire was used to identify risk factors in the population and was administered to the study population. Results: A total of 43 of 300 sera tested positive to IgG antibodies, indicating a cysticercosis prevalence of 14.3%. Method of pork preparation and history of epilepsy were found to be strongly associated with seropositivity. Epileptics in this study were two times more likely to be seropositive than non-epileptics. A large proportion (74.0%) of the population had very poor knowledge of cysticercosis, and knowledge of cysticercosis was strongly associated with method of pork preparation and respondents' occupations. Conclusions: A high seroprevalence of human cysticercosis was found in Kaduna South and Chikun Local Government Areas. The main risk and behavioral factors contributing to the high prevalence include poor knowledge of cysticercosis and lack of knowledge on proper pork preparation methods.

“…The 9.6% seroprovalence of human cysticercosis among pig rearers obtained in this study is high compared to the zero (0%) prevalence earlier reported in Nigeria [26], and the 2.4% and 1.3% prevalence reported by Zoli et al [21] in endemic areas of the West African countries of Togo and Benin respectively. Our finding is close to the prevalence of 14.8% and 8.0% obtained in Mexico (an endemic area) by western blot and ELISA respectively [27].…”

“…Prevalence human taeniasis has been reported in Nigeria at 8.6% [23] with 3.7% associated with epilepsy [21,24]. Although the recognition of its status as a serious and emerging threat to public health is increasing, the incidence data in humans are very limited owing to a lack of adequate surveillance, monitoring and reporting systems; consequently, epidemiological information is not extensive.…”

Introduction: In Nigeria, Taenia solium cysticercosis is a problem in rural areas where most pigs are kept and in urban areas where infected pork can be consumed. Methodology: We performed enzyme linked immunosorbent assays on serum samples collected from pig rearers in Jos, Nigeria, to determine the prevalence of IgG antibodies.Results: Of 125 subjects tested, 12 (9.6%) were positive for T. solium. Seroprevalence did not differ significantly (P>0.05) according to education, age, occupation, study location, gender or whether the subjects consumed pork. However, a statistical difference (P<0.05) in seroprevalence was observed according to type and availability of toilet used, personal hygiene after using the toilet, and type of pig management practiced. Females were about two times more likely to be seroprevalent than males (OR=1.7; 95% CI= 0.43-6.67; P=0.4) and subjects who consumed pork were four times more likely to have anti T. solium antibodies than those who did not eat pork (OR=4.2; 95%CI=0.52-33.57; P=0.2). Those who defecated in the bush were 8.3 times more likely to suffer from T. solium infection than those who used water system toilets (OR=8.3; 95%CI=1.56-43.7; P=0.01). Subjects who did not wash their hands after defecating were 6 times more likely to contract T. solium compared to those who washed their hands with water ( OR=5.5; 95% CI=1.39-21.89; P=0.01). Conclusion: Our results show that using a toilet and practicing good personal hygiene can reduce cases of T. solium infection in a community.

“…T. solium cysticerci are found in almost all tissues of pigs (Boa et al 2002), but mostly remain asymptomatic. Although the disease usually remains asymptomatic, it could cause production and economic losses in the pork production (Zoli et al 2003).…”

Morphological characterization of Cysticercus cellulosae in naturally infected pigs in Punjab (India)

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).
