“…All 60 parasites obtained from abattoirs in two different regions of Cameroon were identified as F. gigantica , suggesting that this species is the predominant Fasciola species in Cameroon. This confirms previous studies in the country where morphology was used to identify F. gigantica as the most prevalent species in the country [32, 33] and the surrounding Central-West African region [14, 15]. The distribution of F. gigantica is dictated by the distribution of the snail intermediate host, L. natalensis , which prefers humid tropical climates found across many regions of SSA [1, 36].…”

BackgroundCattle rearing in Cameroon is both economically and culturally important, however parasitic diseases detrimentally impact cattle productivity. In sub-Saharan Africa bovine fasciolosis is generally attributed to F. gigantica, although understanding of Fasciola species present and local epidemiology in individual countries is patchy. Partly limited by the lack of representative surveys and understanding of diagnostic test perfromance in local cattle populations. The aims of this paper were to determine the Fasciola species infecting cattle, develop a species specific serum antibody ELISA, assess the performance of the ELISA and use it to assess the prevalence of F. gigantica exposure in two important cattle-rearing areas of Cameroon.ResultsA random sample of Fasciola parasites were collected and were all identified as F. gigantica (100%, CI:94.0–100%, n = 60) using RAPD-PCR analysis. A F. gigantica antibody ELISA was developed and initially a diagnostic cut-off was determined using a sample of known positive and negative cattle. The initial cut-off was used as starting point to estimate an optimal cut-off to estimate the best combination of sensitivity and specificity. This was achieved through sampling a naturally infected population with known infection status (cattle slaughtered at Bamenda abattoir, North West Region (n = 1112) and Ngaoundere abattoir, Vina Division, Adamawa Region (n = 776) in Cameroon). These cattle were tested and results analysed using a Bayesian non-gold standard method. The optimal cut-off was 23.5, which gave a sensitivity of 65.3% and a specificity of 65.2%. The prevalence of exposure to F. gigantica was higher in cattle in Ngaoundere (56.4% CI: 50.2–60.0%) than Bamenda (0.6% CI: 0.0–1.4%).ConclusionFasciola gigantica was identified as the predominant Fasciola species in Cameroon. Although the sensitivity and specificity F. gigantica antibody ELISA requires improvement, the test has shown to be a potentially useful tool in epidemiological studies. Highlighting the need for better understanding of the impact of F. gigantica infections on cattle production in Cameroon to improve cattle production in the pastoral systems of Central-West Africa. This paper also highlights that non-gold standard latent class methods are useful for assessing diagnostic test performance in naturally-infected animal populations in resource limited settings.Electronic supplementary materialThe online version of this article (10.1186/s12917-018-1762-z) contains supplementary material, which is available to authorized users.

“…The prevalence distribution of bovine fasciolosis is mapped (fig. 1) according to available data published between 1980 and 2016 (Schillhorn van Veen, 1980, Nwosu & Srivastava, 1993; Ngwu et al, 2004; Opara, 2005; Ekwunife & Eneanya, 2006; Adedokun et al, 2008; Umar et al, 2009; Ibironke & Fasina, 2010; Sugun et al, 2010; Gboeloh, 2012; Omoleye, 2012; Odigie & Odigie, 2013; Abraham & Jude, 2014; Ardo et al ., 2014; Magaji et al , 2014; Ngele & Ibe, 2014; Onyeabor, 2014; Yahaya & Tyav, 2014; Ejeh et al, 2015; Elelu et al, 2016). The high prevalence rate from liver condemnation in a 3-year period reported in Lagos State (Ibironke & Fasina, 2010) can be explained by the fact that this State is the commercial nerve centre of Nigeria, with a very large human population, and many cattle from all over the country are often slaughtered at the abattoir.…”

“…Disparity amongst the virtual incidence of the two species of Fasciola in cattle slaughtered in abattoirs situated in diverse regions of the country may possibly be clarified by the deviation in the climate-ecological conditions of the areas feeding the abattoirs. Quite a lot of studies in other African countries, however, indicated that F. gigntica is the leading if not only species ubiquitous (Phiri et al, 2005;Pfukenyi and Mukaratirwa, 2004;Kithuka et al, 2002;Opara, 2005).…”

The study was conducted to explore the incidence and economic loss related with fasciolosis in cattle at Wolkite town, Community Abattoir, Wolkite, Ethiopia. A cross-sectional study was conducted from February, 2016 -May, 2016 on bovine fasciolosis in Wolkite town, Community Abattoir. From a total of 392 cattle inspected coprologically 41.8% (164) were found positive for fasciolosis. The occurrence of cattle fasciolosis in the study sites was considerable (p<0.05) which is mainly determined based on body conditions. Post mortem assessment was conducted on a total of 392 bovine and 41.8% were found infected by Fasciola. Fasciola hepatica was the major Fasciola species causing bovine fasciolosis at the study areas. Analysis of the abattoir data indicated a total yearly liver disapproval was identified to result in 182582.4 Ethiopian birr. Likewise, the mean carcass weight loss was calculated to be 4984499.52 Ethiopian birr due to fasciolosis in cattle. The total yearly monetary loss due to fasciolosis in Wolkite town, Community Abattoir was calculated to be 5167081.92 birr. The results of the present study thus illustrated that the incidence and economic loss of fasciolosis in bovine slaughtered at Wolkite town, Community Abattoir was exceptionally elevated and necessitates urgent need for control and prevention of the parasite in the study area in specially and in Ethiopia as a whole.
