Abstract

The study aims to throw some light on a large diversity of mite species inhabiting domestic rabbits’s manure, which is produced on a small scale or in farmers houses in the Tanta Governorate, and evaluate the changes in hematological values and biochemical parameters in rabbits infested with the Psoroptes cuniculi parasite. This study reports an incidence of mites (Arachnida: Acari) that inhabit domestic rabbits. A total number of ten rabbits were collected from Tanta. Rabbits were divided to two equal groups (n=5). The first group was used as the healthy group, and the second group was naturally infested with Psoroptes cuniculi. Chemical analyses (hematology, biochemistry). The data showed that in total, 49 mite species belonging to 17 families within three suborders under two orders were collected and identified. The order Acariformes was categorized into the suborders Actinedida, Acaridida, and Oribatida. Meanwhile, the order Parasitiformes was contained only by suborder Gamasida. The level of Hb, PCV, RBC, and eosinophils decreased significantly in all the infested rabbits, but WBC and lymphocytes were increased significantly. There were notable changes in variation in total protein, albumin, β globulin, total globulin, and creatine kinase levels between the groups. The results showed the lowest level of SOD but an increase in CAT and GST in infested groups compared to healthy groups. Mites can cause abnormal hematological and biochemical changes, with the severity of these changes influenced by the duration of the infestation and the extent of the disease.
