Identification of Sand Flies (Diptera: Psychodidae) Collected from Cutaneous Leishmaniasis Endemic Focus in the Ho Municipality, Ghana

Leishmaniasis, is a vector-borne disease transmitted to humans through the bite of infected female sand flies. Active and continuous monitoring of the sand fly is an important aspect of disease control. Thus, the correct identification of its vectors is paramount in this regard. Objective: The study was conducted to morphologically and molecularly identify female sand fly species in a cutaneous leishmaniasis endemic focus collected in three villages in the Ho Municipality of the Volta region. CDC light traps and sticky paper traps was used for the collection of the sand flies. The morphologically identified sand flies was molecularly confirmed by running PCR with the mitochondrial cytochrome c oxidase gene subunit I (COI) primers and DNA sequenced. A total of 537 sand flies was collected, made up of 363 females and 174 males.  Eleven different species of sand flies was morphologically identified – one Phlebotomus species and ten Sergentomyia species. The PCR amplified products showed bands of molecular weights 658 base pairs for the primers. The molecular identification using the 658-bp fragment of the (COI) gene was congruent with the morphological identification

Zoonotic Gastrointestinal Parasites of Baboons (Papio anubis) in the Shai Hill Reserve in Ghana

Several intestinal parasites of baboons are of zoonotic importance, especially where there is considerable interaction between the baboons and humans. The identification of gastrointestinal parasite infections of baboons (Papio anubis) was undertaken at the Shai Hills Reserve Resort, Ghana. A total of 51 faecal samples were collected randomly from individual baboons (51) and examined for cysts, eggs, and larvae of parasites of medical importance, using the direct saline smear and formol-ether concentration technique. The baboons were in 7 troops and were grouped into juveniles, subadults, and adults. The survey showed that 92% of the baboon samples examined were infected with at least one or more parasite(s) of medical importance. Hookworm had the highest prevalence of 38.39% followed by Ascaris lumbricoides (22.32%), whilst Diphyllobotrium latum recorded the lowest prevalence of 0.89%. Adults had the highest prevalence of A. lumbricoides (35.42%). Hookworm (47.92%) occurred most in the juveniles. This is the first report of intestinal parasitic infection in baboons within the Shai Hills Reserve. The results showed a high level of multiparasitism in the nonhuman primates, thus the need for possible interventions to maintain ecosystem health and control the infections as they may be a potential source of transmission to humans

Burdens of Ascaris spp. and Cryptosporidium spp. parasites in farm pigs in Ghana

Abstract Background Worldwide, intestinal parasites significantly affect the health and production of pigs. Objective This study assessed the prevalence of Ascaris and Cryptosporidium infection in pigs in the Ejisu‐Juaben Municipality of Ghana. Method Faecal samples from two hundred (200) pigs on four different farms (labelled A, B, C, D) were processed using the Kinyoun modified Ziehl‐Neelsen method for Cryptosporidium and the Formol‐ether sedimentation method for Ascaris and microscopically examined to identify parasites to the genus level. Results The prevalence of Ascaris and Cryptosporidium in the pigs was 76% and 77%, respectively. The weaners had the highest Ascaris prevalence (96.15%) with the piglets recording the least (59.25%). On the other hand, the piglets had the highest prevalence (88.89%) for Cryptosporidium with the boars, sows and weaners recording 75.86%, 75.42% and 73.08% respectively. The prevalence of Ascaris was high in farm D (78.57%) while Cryptosporidium was highest in farm C (86.11%). Generally, there was a significant difference (p = 0.044) in the mean distribution of Cryptosporidium in the pigs. Conclusion The high burden of Ascaris and Cryptosporidium infections in the pigs suggest the need to adopt and implement effective control measures

Spatial and Seasonal Patterns of Tick Infestations in Kassena-Nankana Livestock

The ability of ticks to adapt to different ecological zones, coupled with the spread of infectious pathogens negatively affects livestock production and thus, there is a need for better control strategies. However, control measures within a geographical region can only be effective if there is available information on tick population dynamics and ecology. This study focused on ticks infesting livestock in the Kassena-Nankana Districts of the Upper East Region of Ghana. The ticks were morphologically identified, variables such as season, animal host, and predilection sites were recorded, and the data were analyzed using STATA version 13. Out of 448 livestock examined, tick infestation in cattle was (78.60%), followed by sheep (25%) and goats (5.88%). A total of 1,550 ticks including nymphs (303) and adults (1,247) were collected. Adult ticks were found to be significantly associated with season (p<0.001), with a high burden in the wet season. The nymph burden and body parts of livestock hosts were significantly associated with more nymphs collected from male animals than females (p<0.001). Three genera of ticks, Amblyomma (62.97%), Hyalomma (18.71%), and Rhipicephalus (18.32%) were morphologically identified with the most predominant tick species recorded as Amblyomma variegatum (62.97%). Matured A. variegatum was sampled primarily in the wet season with their predilection site as the udder/scrotum (p<0.001). However, adult Hyalomma truncatum was observed to have a significant association with the anal region (p<0.001). Findings from this study are essential for formulating tick control measures to prevent the spread of infectious pathogens
