Hematological, Biochemical and Histopathological Studies on Marsh Frog, Rana ridibunda, Naturally Infected with Waltonella duboisi

A.M. Al-Attar
The present study was aimed to evaluate the impact of Waltonella duboisi naturally infection in the marsh frog, Rana ridibunda. Healthy and infected frogs of both sexes were collected from Al-Qatif and Al-Hassa farms, Eastern Province, Saudi Arabia. The hematological, biochemical and histopathological changes were estimated in infected male and female frogs compared with healthy frogs. The values of red blood cell count, hemoglobin concentration, hematocrit, mean cell volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration and white blood cell count were statistically decreased in infected frogs. Infection with Waltonella duboisi induced significant reduction in the levels of serum glucose and total proteins, while the values of triglycerides cholesterol, creatinine, glutamic pyruvic acid transaminase and glutamic oxaloacetic acid transaminase were significantly elevated. Histopathological examination of stomach, small intestine, liver showed the larval developmental stages of Waltonella duboisi. A partially abnormal of testis and ovary structures with pronounced disturbance in quantity and quality of spermatogenesis and oogenesis processes were noted in infected of both sexes of frogs. From the present study, it is obviously that Waltonella duboisi caused many severe physiological and histopathological alterations in both sexes of the marsh frogs. Thus, more sincere ecological and scientific efforts are required to rescue the marsh frog population from parasitic infection, pathogenic factors and increases of mortality rate.

The main purpose of this scientific paper is to report new subject and results about the impact of studied parasite,Waltonella duboisi, on marsh frog. The hematological, biochemical and histopathological are very important indicators which reflect the effect of this parsite on marsh frog. The conclusion is also very intresting.
