“…The prevalence of fascioliasis is not uncommon in the country particularly in the province of Balochistan where sheep rearing is the biggest economic resource of rural population (Nawaz and Nawaz,1987). Economic losses in sheep and cattle has also been recorded by (Njeruh, 2004).…”

| The study was conducted to determine the prevalence of fascioliasis in sheep in Quetta district from January to June 2007. Two hundred and fifty liver samples along with gall bladder and bile ducts were collected from sheep. Over all prevalence of liver fluke infestation in sheep was recorded as 30% in young and adult and 32% in aged sheep. Out of these positive samples Fasciola hepatica was found 50% and Fasciola gigantica 10% in case of young whereas in adults 20% with fasciola hepatica and 14%with Fasciola gigantica and in aged sheep the prevalence was recorded as 33.33% and 13.33% with fasciola hepatica and fasciola gigantica respectively. Variable degree of gross lesions were noted in affected livers included cholangitis (63.15%), biliary obstruction (57.89%), fibrosis (68.42%), hyperplasia (60%), haemorrhages (47.36%), enlargement (52.63%), fibrinous exudates (63.15%) and oedema (57.0%) in sheep during the study period. From this study it is clear that fascioliasis is a serious problem for sheep in Pakistan with highest percentage of Fasciola hepatica followed by Fasciola gigantica which causes damaging of liver with variable degrees of inflammation, haemorrhages, hyperplasia and enlargement of livers.

“…Corresponding with the numerous studies from various countries, reviewed studies further showed that the infection rate was significantly higher in young animals than in old animals (73)(74)(75). However, only one study compared prevalence in males and female in cattle that showed highprevalence of fasciolosis in males than females in the lowthroughput abattoirs (LTPAs) which corresponded with reports from other studies (21,74,(76)(77)(78), but the HTPA reported high infections in the females (36). Animals with poor body conditions scores showed to be more susceptible to infection (21,74,79,80).…”

Occurrence of Fasciola (Digenea: Fasciolidae) Species in Livestock, Wildlife and Humans, and the Geographical Distribution of Their Intermediate Hosts in South Africa—A Scoping Review

2022

View full text Add to dashboard Cite

This review was conducted to provide an update on the status of the occurrence of Fasciola species in livestock, wildlife and humans, and the geographical distribution of snail intermediate host (IH) species in South Africa. The literature search was conducted on four electronic databases using the Boolean operators in combination with predetermined search terms for thematic analysis. Results showed that Fasciola species have been reported in six out of nine provinces of South Africa in the last six decades (1960–2021), with both F. hepatica and F. gigantica infecting vertebrate hosts and F. hepatica and Fasciola spp infecting humans. Results also showed that most studies relied on morphological identification of eggs and flukes without molecular confirmation, which might have led to the misidentification of specimens, especially when immature. Fasciola hepatica has been documented in Limpopo, Mpumalanga, and KwaZulu-Natal provinces. The occurrences of Galba truncatula as the probable snail IH for F. hepatica in the three provinces has been documented while Pseudosuccinea columella has only been documented in Mpumalanga and KwaZulu-Natal provinces. The occurrence of F. gigantica to date has been reported in Mpumalanga and KwaZulu-Natal provinces, with overlapping distribution with F. hepatica. Radix natalensis, the main IH of F. gigantica has been documented in all the three provinces, while the two alien Radix species (R. auricularia and R. rubiginosa) were documented in KwaZulu-Natal province and have been implicated elsewhere with the transmission of F. gigantica. The presence of Fasciola spp eggs and antibodies in humans were documented in the Eastern Cape and the Western Cape provinces, where both P. columella and G. truncatula are known to be present. The prevalence of Fasciola spp infection in livestock ranged from 9.1 to 37.67 %, with an estimated annual financial loss ranging from R44930.26-129901 in cattle production in the Eastern Cape province of South Africa. This review reaffirms the scarcity of information on the occurrence and burden of fasciolosis in South Africa, and further highlights the importance of future research covering all provinces of the country and assessing the public health significance of the disease in resource-poor livestock communities in the areas where the parasite is endemic.

“… Sex Both males and females seem to be equally likely to have fasciolosis. Studies showed that Fasciola infection due to either F. gigantica or F. hepatica was more prevalent in males (Kithuka et al ., 2002; Njeruh et al ., 2004; Kedir et al ., 2012; Munyeme et al , 2010; Betebo, 2017); however, the difference was not significant, with the exception to that reported by Kedir et al . (2012) in small ruminants.…”

Fasciolaspecies and their vertebrate and snail intermediate hosts in East and Southern Africa: a review

2019

View full text Add to dashboard Cite

A systematic review was conducted focusing on the distribution of Fasciola species and their snail intermediate hosts (IHs) in East and Southern Africa. The reviewed literature showed that both Fasciola hepatica and F. gigantica are present in East and Southern Africa, and infect a wide range of domestic and wild ruminants. Fasciola gigantica was reported in six East African and five Southern African countries, where Radix natalensis (found in low altitudes) was reported to be the main IH. Fasciola hepatica was reported in Tanzania and Ethiopia (East Africa), and in South Africa and Zimbabwe (Southern Africa), where Galba truncatula (found in high altitudes) was documented as the IH in all countries except in Zimbabwe. Both Fasciola species were documented in Tanzania, Ethiopia, Zimbabwe and South Africa. An overlap of the two was observed in areas with an intermediate altitude in Ethiopia and South Africa, where Pseudosuccinea columella was widespread and assumed to transmit both species. Pseudosuccinea columella has been reported in South Africa and Namibia, and proven to transmit F. gigantica in South Africa; its role in Namibia in the transmission of Fasciola species has not been reported. Other lymnaeid species such as R. rubiginosa were reported in South Africa, and R. auricularia in South Africa and Botswana; their role in the transmission of Fasciola species has not been proven. Future studies should aim to determine the role of P. columella in the geographical spread of the two species in East and Southern African countries.
