“…There was a negative and non-significant correlation between mean haematocrit and mean tick load. This finding is similar to that obtained by Mamoudou et al (2015); Abdoulmoumini et al (2017) who propounded that ticks and co-infection with TBDs and trypanosomes negatively affected the packed red blood cell volume of cattle. Because the decrease in haematocrit is caused by several factors, tick presence alone without considering the impact of other pathogens and environmental factors will not be sufficient to account for this phenomenon.…”

“…The present prospection led to the identification of four species of ticks with H. truncatum being the most prevalent of the species encountered. Similar work conducted in Cameroon (Awa et al, 2015;Mamoudou et al, 2015) indicate a low representation of H. truncatum and lack of Boophilus decoloratus. The number of species encountered in this study are more than those reported by Abah et al (2017) in the same study area.…”

“…It is common in west Africa (Yao-Acapovi et al, 2018;Diaha-Kouame et al, 2019), but few studies have reported its occurrence in central Africa (Mebanga Sassa et al, 2014;Silatsa et al, 2019). Although few reports already exist on the occurrence of ticks in North Cameroon (Mamoudou et al, 2015;Abah et al, 2017), there is need to update on its occurrence and impact on livestock. The presence of ticks and their co-existence with trypanosomes and TBDs in cattle in North and Adamawa regionsled to the alteration of their haematocrit (Mamoudou et al,2015;Abdoulmoumini et al, 2017).…”

To control ticks in rangelands, there is need to know their species composition, dynamics and impact, reason for which a study was conducted in the locality of Boklé in Garoua in the North region of Cameroon to identify the different species of ticks on cattle as well as correlating tick burden and haematocrit.…”

Ticks and Tick-Borne Diseases (TBDs) represent a scourge to livestock health and production in Cameroon. Information on their ecology and impact on cattle in the North region of Cameroon which is an important livestock zone of Cameroon is scanty, reason why a cross sectional study in the rainy season was conducted from May to September 2015 in the locality of Boklé-Garoua in the North region of Cameroon with the aim of identifying the different species of ticks and relate tick load with haematocrit. Ticks were collected once a week from six adult cattle and identified using standard keys. In total, 404 ticks were collected and classified under Amblyomma variegatum, Hyalomma truncatum, Rhipicephalus sanguineus and Rhipicephalus (Boophilus) decoloratus. Hyalomma truncatum (50%) was the most frequent species, whileRhipicephalus sanguineus(1%)was the least. There was a negative and statistically non-significant(r=-0.170, p>0.05)correlation in mean tick load and haematocrit of cattle.The results of this study indicate the occurrence of four species of ticks and their negative but non-significant effect on haematocrit of cattle from the north region of Cameroon. Studies on the diseases transmitted by these vectors are underway and will indicate the impact and need for their control in Cameroon.

“…The infection rate for T. congolense was 1.96% in July for Kimototok. This is of more interest in this study considering that these species are pathogenic to cattle [29,30], regardless of their lower prevalence. The finding of pathogenic species of trypanosomes in the study area is also of relevance to pastoralists, as it confirms risk and vulnerability of their cattle to the disease AAT.…”

Influence of Seasonal Cattle Movement on Prevalence of Trypanosome Infections in Cattle in the Maasai Steppe, Tanzania

Animal African Trypanosomosis is a Neglected Tropical Disease with significant impacts to pastoral community livelihoods. Our study sought to determine the influence of seasonal cattle movements on the prevalence of trypanosome infections in cattle in the pastoral areas of the Maasai Steppe. Identification of spatial and temporal dynamics of trypanosome infections in cattle is essential for designing effective control strategies. To identify potential hotspots of trypanosome transmission, we worked with 5 pastoralists in each of 3 villages in the Maasai Steppe of northern Tanzania, and consecutively sampled 10 of each of their cattle in 3 periods, covering both wet and dry season grazing ranges (July 2017 to January 2018). Each time blood was collected from the cattle, a prophylactic dose of diminazene aceturate was administered to clear any parasites acquired in the previous 3 months. We then used participatory mapping techniques to identify the areas where the pastoralists had grazed their herds since the last sampling period, and interviewed them about any disease control methods they practice. Trypanosome infections in the sampled cattle blood were detected using nested polymerase chain reaction with ITS-1 primers. The overall prevalence of trypanosome infections across all sample periods and villages was 12%, though this varied distinctly by season and grazing area. Prevalence in July 2017 (19.33%) was significantly higher than prevalence in October 2017 (2%) (p < 0.05). A total of 45 grazing areas were identified and cattle acquired trypanosome infections in almost half of these (n = 21). Targeted awareness on seasonality and hotspot areas of trypanosome infections will help Maasai pastoralists to plan movement of their cattle strategically to avoid disease risk. These results also suggest enhanced control strategies for Trypanosomosis during the months of the year when cattle are moved further from homesteads to graze in hot spot areas.
