“…Our results show that T. vivax was the predominant species responsible for bovine trypanosomiasis in the Savannah district, consistent with previous reports [1,2]. The predominance of T. vivax could be explained by the agroclimatic conditions that favor the development of some riverine tsetse flies (G. tachinoides and G. palpalis gambiensis) and Savannah-type tsetse flies (G. morsitans and submorsitans), which are all known to be potential vectors of trypanosomes, particularly T. vivax [17].…”

Bovine trypanosomiasis is a significant health concern for livestock intensification in Côte d’Ivoire. This study aimed to determine the prevalence and distribution of pathogenic trypanosomes and identify the most infected cattle breed in northern Côte d'Ivoire. We examined 700 cattle and found that polymerase chain reaction (PCR) was more sensitive (12.3%) than microscopic observation (5.6%). Among the trypanosome species detected in naturally infected cattle, Trypanosoma vivax was 7.3%, Trypanosoma simiae tsavo was 6.7%, and Trypanosoma congolense was 0.4%. The overall prevalence of trypanosome infection in all cattle breeds was 12.3%, while the prevalence in individual breeds was 14.8%, 7.3%, 10.6%, and 12.3% for N’Dama, Baoule, Zebu, and Mere breed, respectively. The infected animals had low packed cell volume, influencing the prevalence. Our findings indicate that bovine trypanosomes are prevalent in Côte d’Ivoire, and their prevalence varies by region and breed. These pathogens include T. vivax, T. simiae tsavo, and T. congolense.

“…Organisms belonging to the genus Trypanosoma, which are transmitted mainly by the tsetse fly, cause this disease. Tsetse flies have an area of distribution of over 10 million square kilometers in Africa, representing 38 countries [2]. The tsetse flies mainly transfer the trypanosomes from one animal to another.…”

“…There should be an identical susceptibility of both sexes to the parasite genus or its vectors. These results confirm current results (Acapovi-Yao et al, 2010). These researchers demonstrated that the phenotype, sex and age class of the cattle did not influence the prevalence of trypanosome infestations in Korhogo and Odiénné.…”

Anaplasma phagocytophilum, a bacterium transmitted by ticks, is responsible for granulocytic anaplasmosis, an emerging zoonosis that has never been reported nor identified previously in Benin and in the West African sub-region. This study is designed not only to investigate the prevalence of the disease and evaluate mortalities recorded at Kpinnou farm after importing Girolando cattle from Brazil in 2014 but also to assess the prevalence of the emerging disease in Benin in the year 2014 period. A total number of 1427 ticks were collected, including 5 ml of blood from each one hundred cattle. Microscopic diagnosis reveals the presence of Rhipicephalus (Boophilus) spp., Rhipicephalus microplus, Amblyomma variegatum, Rhipicephalus spp and Hyalomma spp. Blood analysis results reveal the occurrence of 55% positive cases for A. phagocytophilum. Considering the effeiciency of the methods, 100% of A. phagocytophilum reported as positive by microscopy appear to be also positive with molecular analysis. PCR has greater sensitivity and specificity even with microscopy showing appreciable specificity. This study concludes that Anaplasma phagocytophilum is the primary suspect responsible for the massive deaths observed in cattle in the study area.

“…These small forests are off-limits and constitute a favourable biotope for the proliferation of tsetse flies. The incriminated vectors are Glossina palpalis palpalis (Robineau-Desvoidy 1830), G. palpalis gambiensis (Vanderplanck 1949) and G. tachninoides (Westwood 1830) (Acapovi- Yao et al 2010;Gouteux & Millet 1984). According to some authors (Djohan et al 2015;Jamonneau et al 2003), G. palpalis gambiensis and G. tachninoides are the vectors responsible for the transmission of animal trypanosomiasis.…”

Bovine trypanosomiasis is a parasitic disease caused by protozoans of the genus Trypanosoma. The disease cause economic losses in livestock production. In order to determine the status of research on this disease in Côte d’Ivoire, we used the systematic review method and meta-analysis. Three electronics databases, namely Google Scholar, PubMed and CrossRef were used to search for publications on trypanosomiasis prevalence that met our inclusion criteria. Twenty five articles were identified, 11 of which met the inclusion criteria. Bovine trypanosomiasis prevalence of 2.99% (95% confidence interval [CI]: 2.96% – 3.01%) to 25.28% (95% CI: 25.17% – 25.38%) were recorded between 1960 and 2021. The analyses showed that the most infected regions were the Bagoue 11.26% (95% CI: 11.25% – 11.27%), Bounkani 14.94% (95% CI: 14.93% – 14.95%), Gbeke 10.34% (95% CI: 10.33% – 10.35%), Marahoue 13.79% (95% CI: 13.78% – 13.80%), Poro 8.50% (95% CI: 8.49% – 8.51%), and Tchologo 11.83% (95% CI: 11.82% – 11.84%).The most sensitive diagnostic method used was the polymerase chain reaction (PCR). The species of trypanosomes diagnosed were Typanosoma vivax 4.99% (95% CI: 4.97% – 5.01%), T. congolense 1.51% (95% CI: 1.49% – 1.52%), and T. brucei 0.61% (95% CI: 0.59% – 0.62%). Despite some variation, the prevalence of bovine trypanosomiasis in Côte d’Ivoire caused mainly by T. vivax has increased in the years between 1977 and 2017. Efforts to control tsetse and other mechanical vectors should also be put in place to minimize its transmission.Contribution: The authors studied the prevalence of bovine trypanosomiasis using the systematic review method and MA in order to determine the status of research on this disease in Côte d’Ivoire.
