Human and animal fasciolosis: coprological survey in Narok, Baringo and Kisumu counties, Kenya

Abstract

Fasciolosis is caused by digenean trematodes of the genus Fasciola. The principal definitive hosts are cattle, sheep and goats. Humans are infected as accidental hosts. Fasciolosis is one of the major neglected tropical diseases and is considered an emerging zoonotic infection. This study was aimed at determining the prevalence of human and domestic animal fasciolosis in selected counties in Kenya. Stool samples for Fasciola diagnosis were collected from humans and domestic animals and transported to the laboratory at Egerton University and processed using sedimentation technique and examined for the presence of eggs. A total of 272 human samples collected were all negative for Fasciola eggs. A total of 582 domestic animals (cattle (46.0%), sheep (29.9%) and goats (24.1%)) samples collected had overall prevalence of 30.9% for Fasciola infection. There was no significant differences (p0.05) between prevalence of fasciolosis and origin of the animals, sex and season. There was a significant difference (p0.05) between the prevalence of fasciolosis and domestic animals, age and body condition. The prevalence of fasciolosis was high in two irrigation schemes which favor the breeding of intermediate host snail and grazing of animals along the irrigation canals where metacercaria of Fasciola parasites could be present on the vegetation. Though human fasciolosis was not detected in this study, the presence of animal fasciolosis can pose public health risk because of its zoonotic nature. It is therefore, important to introduce measures which would assist reduce exposure of animals to Fasciola infection.

Serological Prevalence of Anti-Fasciola Hepatica Antibodies in Sheep

“…In the current study, positive rate of infection showed that no significant variation was found between females and males [18,37,38]. These findings means that either F. hepatica does not associated with sex of animals [23], or both sexes exposed to the same risk factor of infection such as contaminated grass [39].…”

High prevalence of liver fluke infestation, Fasciola gigantica, among slaughtered cattle in Boyolali District, Central Java

“…would prioritize nutrition from intake feed for immunity and, thus, decreased energy storage leading to lower BCS ( Levi et al ., 2020 ). Association of low BCS to cattle fasciolosis was also reported in Nigeria ( Shinggu et al ., 2019 ), Kenya ( Kipyegen et al ., 2017 ), and Pakistan ( Khan et al ., 2020 ).…”

Mycosorb A+® como adsorbente de micotoxinas en la dieta sobre la salud y la producción en cuyes

“…El riesgo de intoxicación por micotoxinas en los cuyes fue evaluado a partir de los valores de la Tabla de asociación tetracórica de 2×2 simple de estrato único (TABLA II), a fin de analizar 2 variables dicotómicas: una independiente (exposición) y una dependiente (enfermedad), donde las micotoxinas se manifiestan con enfermedad en los animales [27].…”
