Abstract

The present study aimed to detect the parasitic fauna associated with black rats (Rattus rattus) from southeastern Algeria. It showed the presence of seven species of parasitic fungi namely Penicillium sp. (Prevalence Pr=91.3%), Aspergillus niger (Pr=91.3%), Alternaria sp. (Pr=58.7%), Cladosporium sp. (Pr=87%), Microsporum sp. (Pr=19.6%), Trichophyton sp. (Pr=21.7%) and Chrysosporium sp. (Pr=10.9%), noting that saprophytic fungi were the most recorded. On the other hand, according to the richness (S), adults (S = 7) and sub-adults (S = 7) of black rats were the most infested, with leaning for males compared to females, considering all the isolated species as satellites except the Chrysosporium sp. (2.9%) which is presented as a rare species. Concerning parasitic bacteria, aged rats were the most infected followed by adults and sub-adults where total coliforms were present in all individuals of the three classes tested. However, fecal streptococci were noted with a similar infestation rate in all age groups. Unlike this, clostridium sulfite-reducer (CSR) was mostly recorded on aged rats. Concerning the endoparasites found in the intestines of black rats, the pinworms (Syphacia muris, Syphacia obvelata, and Aspiculuris tetraptera) were more abundant than the other species. Hence, the current study allowed us to demonstrate that black rats can be considered an important reservoir of several microorganisms that can hold germs and represent a threat to biomedical and veterinary public health.
