“…Therefore, coccidiosis severity is positively correlated with the charge of ingested oocysts. The pathogenicity of coccidia depends on the species involved, the number of oocysts ingested and the host’s immune competence (Dakpogan et al 2012).…”

The prevalence of coccidiosis was determined and Eimeria species were identified in farms at different locations in the Bejaia region, Algeria. The study was conducted from February to December 2016. Unvaccinated birds were selected randomly. Samples from litter and faeces were collected randomly (147 and 109, respectively). Necropsy and parasitological examinations were carried out using standard methods. Of the samples examined, 93 out of the 147 litter samples and 78 out of the 109 intestinal content samples were infected with Eimeria oocysts (63.26% and 71.55%, respectively). Mixed infections with Eimeria spp. were observed in some of the positive farms, with an overall prevalence of 54.28%. Five species of Eimeria (viz. E. acervulina, E. tenella, E. maxima, E. brunetti and E. mitis) were identified with different indices. Eimeria acervulina followed by E. tenella were the predominant species infecting chickens at the farms visited (32.05% and 26.92%, respectively). Statistically, the most prevalent Eimeria spp. was E. Acervulina (p < 0.05). This study demonstrated that coccidiosis is an omnipresent parasitic intestinal disease. It could strongly decrease production performance in broiler chickens.

“…The high prevalence of infestations could be explained by non-compliance with prophylaxis plans on poultry farms, i.e. inappropriate management of litter and sanitary emptying, as coccidian oocysts sporulate very easily in poultry house litter(Dakpogan et al 2012). Moreover, our prevalence is higher than that reported by other studies: 54.3% in Turkey(Karaer et al, 2012), 31.7% and 39.6% in India(Sharma et al, 2013), 36.7% and 52.9% in Nigeria(Muazu et al, 2008) in poultry production in general.…”

The main objective of this study was to evaluate the helminth parasites encountered in poultry farms in the peri-urban and rural areas of Bobo-Dioulasso. A total of 160 fecal samples were collected from poultry breeding farms in 2 chicken breeds (exotic and local) and 2 areas (rural and peri-urban). The fecal samples was examined by the flotation method using saturated sodium chloride solution. McMaster technique was used to observe and quantify the oocysts of the different gastrointestinal parasites on the slide. The actors surveyed are all male literate with an average age of 48 ± 8.50 years. The average number held by the actors is 3023 ± 1865 chicken heads. They all have poultry farming as their main activity with an average of 12 ± 5.50 years, only 5% practice agriculture in addition to poultry activity. Of the 160 samples tested, 114 were positive, given an overall prevalence rate of 71.25%. The prevalence rate was significantly influenced by the area (𝜒2 = 11.06, df = 1, 𝑃 < 0.001) and the type of intestinal parasite (𝜒2 = 155.65, df = 2, 𝑃 < 0.001). Three types of gastrointestinal nematodes were responsible of these infections therefore Eimeria sp (53.13 ± 50.06%), Heterakis sp (43.13 ± 49.68%) and Ascaris sp (0.63 ± 7.91%). In positive samples, the number of parasites was found to be between 10 and 85000 for oocysts of Eimeria sp, 15 and 2300 for Heterakis sp and 100 for Ascaris sp. The majority of infections in urban area were caused by Eimeria sp (94.12%, p = 0.003), except on one farm where a Heterakis sp infection was encountered. However, in rural area, all intestinal parasites were encountered, with similar level of infections (p = 0.9) between Eimeria sp (50%) and Heterakis sp (49.30%), and which were significantly higher than infections due to Acaris sp (0.07%, p < 0.001). In rural area, mixed infections with Eimeria sp and Heterakis sp or Eimeria sp, Heterakis sp and Ascaris sp were observed in 41.24% and 1.03% respectively of the positive farms. The chicken breed has no significate on the prevalence (𝜒2 = 0.98, df = 1, 𝑃 = 0.3) but the local breed had the high prevalence of intestinal parasites of 77.92% as compared with exotic breed 65.06%. The results showed a high rate of intestinal parasites in poultry farm in rural and peri-urban areas of Bobo-Dioulasso. Therefore, further investigations and design appropriate control strategies in improving management of farms are necessary and strongly recommended.

“…Monensin selectively destroys intracellular sporozoites while remaining relatively noninjurious to the host cell (Chapman et al, 2010). Monensin is primarily coccidiocidal in action and active against Eimeria acervulina, E. maxima, E. brunetti, E. mivati, E. necatrix and E. tenella in chickens (Dakpogan et al, 2013). In Europe, two feed additives, Ealncoban (Elanco, St Cloud, France) and Coxidin (Huvepharma, NV, Belgium), containing monensin have obtained market authorization.…”

We developed a flow-limited physiologically based pharmacokinetic model for residues of monensin in chickens and evaluated its predictive ability by comparing it with an external data set describing concentration decays after the end of treatment. One advantage of this model is that the values for most parameters (34 of 38) were taken directly from the literature or from field data (for growth and feed intake). Our model included growth (changes in body weight) to describe exposure throughout the life of the chicken. We carried out a local sensitivity analysis to evaluate the relative importance of model parameters on model outputs and revealed the predominant influence of 19 parameters (including three estimated ones): seven pharmacokinetic parameters, five physiological parameters and seven animal performance parameters. Our model estimated the relative bioavailability of monensin as feed additive at 3.9%, which is even lower than the absolute bioavailability in solution (29.91%). Our model can be used for extrapolations of farming conditions, such as monensin supplementation or building lighting programme (which may have a significant impact for short half-life molecules such as monensin). This validated PBPK model may also be useful for interspecies extrapolations or withdrawal period calculations for modified dosage regimens.
