A seroepidemiological study of bovine cysticercosis in Bali and Nusa Tenggara, Indonesia

Abstract

<jats:p>Background and Aim: Taenia saginata hazardously affects human and animal health. The distribution of this disease is found almost all over the world. The study aimed to obtain epidemiological information concerning prevalence and the distribution of bovine cysticercosis in Bali and Nusa Tenggara, Indonesia. Materials and Methods: A total of 267 community-owned Bali cattle serum samples from the provinces of Bali, West Nusa Tenggara, and East Nusa Tenggara were examined. The study was conducted by examining the serum of Bali cattle using enzyme-linked immunosorbent assay technique. Risk factors related to cysticercosis that analyzed were sex, breeding type, age, physical condition, source of drinking water, pen condition, and latrine availability. Results: Seven of 91 Bali cattle sera from all regencies/cities in Bali showed a positive result. Those positive sera were originated from Buleleng (1), Gianyar (2), Denpasar (2), and Klungkung (2). Meanwhile, four of 92 Bali cattle sera from West Nusa Tenggara and seven of 84 from East Nusa Tenggara occurred antibodies against T. saginata. We identified that two risk factors that influence the incidence of T. saginata infection in Bali cattle in Bali were the sex and the cattle breeding type. Conclusion: Through this research can be made a map of bovine cysticercosis in Bali cattle in Bali and Nusa Tenggara region. By mapping the disease, it is recommended that the animal health officers should be more accurate when conducting postmortem examination, especially on cattle from a positive region.</jats:p>

Molecular analysis of Taro and Bali cattle using cytochrome oxidase subunit I (COI) in Indonesia

“…The Bali cattle strain is one of the Indonesian banteng descendants (Bos javanicus) that has undergone domestication in the islands of Java, Bali, and Lombok (Besung et al 2019;Dharmawan et al 2020). In 2017, the Bali cattle population in Bali reached 507,000 heads.…”

Perfil epidemiológico do complexo teníase-cisticercose na Província do Huambo-Angola

“…Estes métodos são padronizados para apresentarem alta sensibilidade e especificidade, maior rapidez, simplicidade para o seu uso, repetibilidade e reprodutibilidade, baixo custo e realizados durante as fases de abate, ante e postmortem (WOAH, 2010;Diniz, 2013;Dharmawan et al, 2020).…”

“…A técnica permite o rastreamento e identificação de áreas de alto risco, onde a doença pode ocorrer (Minozzo et al, 2002;Hosseinzadeh et al, 2013;Gonzalez et al, 2015). No entanto, a inspeção post-mortem para a cisticercose bovina está sujeita a falhas, não permitindo detectar todos os cisticercos, principalmente em infeções discretas, visto que por razões comerciais são evitados cortes excessivos que desfiguram a carcaça, além do estágio de degeneração do cisticerco e da habilidade do inspetor influenciarem neste resultado Dharmawan et al, 2020). Como consequência, é subestimada a prevalência real da doença (Dorny e Praet, 2007; e assim permite a entrada de uma grande proporção de carcaças infectadas na cadeia alimentar humana, representando risco para a saúde pública .…”
