“…These different results could be attributed to many factors such as a seasonal variation and their effect on microbial composition, economic conditions, and disease incidence which varied from country to country. In the present study, the percentage result of Trichophyton mentagrophytes was higher than these obtained in Baghdad, Iraq by Al-Samarrae et al (25), who reported that the proportion was 5 (3.6%). These differences in the proportions of each study may result from the difference in the number of isolates enrolled in each study and the skills of laboratory investigators.…”

This study aimed to diagnose the skin lesions in cattle which were suspected to be ring worm in order to determine the species causing these lesions. A total of 40 samples of skin desquamation and hair lesions were collected from cattle in a farm located in the Wasit province during the period October 2021 to March 2022. Diagnosis used to be carried out the usage of direct microscopy of potassium hydroxide, isolation of the fungus the use of Sabouraud dextrose agar supplemented with chloramphenicol and cycloheximide, as well as by way of detecting those fungi through staining with Lactophenol cotton blue. The diagnosis results revealed that infection of cattle with ringworm represented 20/40 (50%) of skin lesions and the majority of the common dermatophytes spp was identified as Trichophyton mentagrophytes 15/20 (75%) and Microsporum canis5/20 (25%) depending on the fungal growth. In conclusion, the most common skin lesions of cattle in Wasit province were identified as ring worm.

Dermatophytosis is considered as one of the most important fungal skin disease affecting both humans and animals otherwise its importance as zoonotic disease. Treatment of ringworm in cattle is expensive and time consuming especially on herd level. Vaccination can be a giant step forward to prevent the occurrence of mycozoonosis between the affected animals with ringworm and susceptible man. Fifty skins scraping samples were collected from animals (cattle, sheep and calves) suffering from skin lesions suspected to be ringworm. Then these collected samples were subjected to mycological examination and identification. T. verrucosum is the main causative agent of collected skin scrapings. Two types of vaccines were prepared from this strain (Culture filtrate and formalin inactivated vaccines). Rabbit model was used for challenge testing of the vaccines. The rabbits were separated into four groups as follow: Each group contained 3 rabbits each one was injected subcutaneously with 1ml of culture filtrate with adjuvant twice for seven days intervals. Group No. 2 rabbits each one was injected intramuscularly with 1 mL formalin-inactivated with adjuvant. The 3rd group is control positive and 4th one is control negative. Vaccination programme is done via injection twice with one week interval and the challenge by scarification of the skin with 0.2 mL of 5×10 7 fungal elements/mL. For 3 days. Humeral immune response was assessed by measuring anti-T. verrucosum antibodies using ELISA technique (direct method). By using statistical analysis of ANOVA, the mean optical density of anti-T. verrucosum specific IgG level in rabbits artificially immunized with culture filtrate with adjuvant vaccine significantly increase from (1.97) post first vaccination to reach (2.43) post second vaccination and still high after challenge with the virulent T. verrucosum strain (2.32) when compared with control positive (1.57). The results revealed that both type of vaccines induce good humeral immune response in vaccinated animals. Culture filtrate vaccine used as a treatment in infected farm animals by two doses within 2 weeks and noted that healing occurred.
