Cutaneous myiasis caused by various Calliphoridae dipteran species is prevalent worldwide and is of particular veterinary and public health concern. Recently, in a scientific exploration of the Guinea Worm Eradication Program to Chad, Africa, we observed that dogs with mutilated ears, based on local awareness, were caused by cutaneous myiasis. In this study, we analyzed epidemiological, morphological, and molecular data on cutaneous myiasis in dogs from Chad.

- Tick-borne pathogens from the Rickettsia genus cause serious diseases in humans and dogs, and climate and land use changes are expanding their vector ranges, potentially introducing new pathogens in unexposed areas.
- A study in Chad found that 43.3% of ticks from domestic dogs were positive for Rickettsia spp., with six identified species including some known zoonotic pathogens like R. africae and R. felis.
- The results highlight a significant diversity of Rickettsia in ticks, particularly in Rh. muhsamae, indicating a risk of rickettsiosis in Chad, and emphasize the need for more research on ticks and these pathogens in the region.
Background: Tick-borne pathogens are understudied among domestic animals in sub-Saharan Africa but represent significant threats to the health of domestic animals and humans. Specifically, additional data are needed on tick-borne pathogens in Chad, Africa. Surveillance was conducted among domestic dogs in Chad for selected tick-borne pathogens to measure (1) the prevalence of antibodies against Anaplasma spp.

Article Synopsis
- Neglected tropical diseases can compromise domestic animal health, with certain parasites like Brugia and Guinea worm being transmitted through these animals.
- In a surveillance study in Chad, researchers found Brugia sp. infections in 10.7% of sampled dogs, showing genetic similarities to both B. malayi and B. pahangi.
- The study revealed higher infection rates in southern Chad and during the dry season, indicating environmental influences on transmission, but found no correlation between Brugia and Dirofilaria immitis infections among the tested dogs.
Article Synopsis
- Dracunculus medinensis, known as Guinea worm, is a parasitic infection targeting both humans and domestic dogs, prompting the need for new treatment methods due to rising infections in dogs.
- Two clinical trials tested the effectiveness of flubendazole (FBZ) injections on GW infections: one on ferrets and another on dogs in Chad, revealing different results between the two.
- Ferrets showed promising results with reduced worm viability, while the dog trial did not demonstrate significant effects, indicating that treatment timing and intervals might need to be adjusted for better outcomes in future research.
Variation in the spatial ecology of animals influences the transmission of infections and so understanding host behavior can improve the control of diseases. Despite the global distribution of free-ranging domestic dogs Canis familiaris and their role as reservoirs for zoonotic diseases, little is known about the dynamics of their space use. We deployed GPS loggers on owned but free-ranging dogs from six villages in rural Chad, and tracked the movements of 174 individuals in the dry season and 151 in the wet season.
