Abstract
The current study was conducted to detect the prevalence of parasitic infection among (62) common tree frogs (Rana Saharica), of different ages, with weights ranged between 1 and 25g. Results: The results revealed that 61 (98%) out of 62 examined common frogs were infected with endo-parasites. The prevalence of infection with protozoal was (86.4%) and (80%) for helminthes, while the mixed infection with both was 65%.
Furthermore, the nematodes (75.5%) were the most prevalent helminthes, also helminthes mixed infection in a single host was reported. Rhabiditis spp., Ophiotaenia ranae, Glypthelmins quieta, Corynosoma spp. were Recovered from the digestive tract of common tree frogs, whereas, the Oplina ranarum and Copromonas subtillis the most prevalent protozoan species were detected from the common frogs.
From the parasitic fauna seen in this study and from the statistical analysis, there were significant differences (P=0.05) between the weight of hosts and the density of infection.
