Isolation of Trichophyton mentogrophytes var mentogrophytes from naturally infected laboratory albino rats: experimental infection and treatment in rabbits

The present study demonstrated for the first time the occurrence of dermatophytosis in naturally infected rats and from asymptomatic and from breeding boxes of white rats kept in animal housing of college of Veterinary Medicine, University of Dohuk, Iraq. The prevalence rate of infection was (28%), clinically infected rats characterized by appearance of scaly ovoid type lesions with crusty edge and patch of hair loss mostly seen on the back, neck and face of the infected rats, itching was reported in some rats. Only one species of the trichophyton, T. mentogrophytes var mentogrophytes was isolated with growth rate (85.71%) of samples collected from clinically infected rats, and (28.57%) from asymptomatic and from breeding cages, the growth was observed within the 21 days at 25ºC on Sabouraud's Dextrose Agar. Lacto phenol cotton blue staining slides of T. mentogrophytes var mentogrophytes revealed both microconidia and macroconidia. Microconidia found in numerous numbers often in dense cluster which were hyaline, smooth walled and predominantly spherical to sub spherical in shape, varying numbers of chlamydoconidia. Spiral hyphae and smooth, thin walled clavate shaped multicelled macroconidia were also present. The study also dealt with experimental infection in rabbits with T. mentogrophytes var mentogrophytes and treated by two drugs, natural herbal preparation of acidic pomegranate (Punica granatum) fruit and synthetic nystatine ointment. The complete recovery of lesions was recorded after 14 days and 21 days of topical application of a pomegranate and nystatine ointment for 5 successive days respectively

Prevalence and pathological study of schistosomiasis in sheep in Akra/Dohuk province, northern Iraq

The occurrence of Schistosomiasis was detected by fecal examination (Formalin- ether centrifugalsedimentation technique) and abattoir Survey during a period from October 2006 to March 2007,andhistopathological study. Schistosomabovis was identified with prevalence rate 11.37 % by fecal examination where as 1.6 % by abattoir survey. Diseased animals exhibited acute clinical signs, which included emaciation, sunken eye, pale mucus membrane and diarrhea. The Infections was more prevalent in age 1-3 years 15.9%. The histopathological findings reveal characteristic lesions in blood vessels and some tissues including thrombosis in veinuoles and mesenteric vein and minute granuloma around the eggs in portal area and fatty necrosis in the liver, cystic structure of some mucosal glandsof the intestine containing eggs, with infiltration of mononuclea

A study on epidemiology of hard tick (Ixodidae) in sheep in Sulaimani

This study was carried out for the period from the beginning March 2009 till end of February 2010 in three zones I, II, and III (Mountainous, Semi-mountainous and foothills and plane) regions, respectively in Sulaimani governorate for distribution of ticks (Ixodidae) that infested sheep. The prevalence rate of infested sheep in all zones was 298 (11.8%) in Sulaimani governorate, and the prevalence rate of infestation in zone-I was 85 (10.1%), in zone-II 94 (11.1%), and in zone-III 11
