Abstract/ Executive Summary:

Dermatophytosis (ringworm), an infection of the superficial keratinized structures of the skin and hair, is the most common contagious skin disease in cattle. It is a remarkable public and veterinary health problem reported from different parts of the world and causes great economic loss. A number of calves were simultaneously affected with this disease in the cattle farm of Bangladesh Livestock Research Institute (BLRI). So, this study was undertaken to develop a suitable treatment approach for controlling the disease in the herd. A total of 20 calves of Red Chittagong Cattle (RCC) were selected for the trial. All the experimental calves were divided into five groups namely – T₀, T₁, T₂, T₃ and T₄. T₀ group was kept as control and T₁, T₂, T₃ and T₄ groups were allowed for treatment. The drugs used for treatment were griseofulvin, streptomycin-penicillin, antihistaminic and vitamin AD3E in group T1; ivermectin, streptomycin-penicillin, antihistaminic and vitamin AD3E in T₂; topical antifungal ointment, griseofulvin, streptomycin-penicillin, antihistaminic and vitamin AD3E in T₃; and topical antifungal ointment, ivermectin, streptomycin-penicillin, antihistaminic and vitamin AD3E in group T₄. No drug was used in T₀ (control).The duration of the experiment was about one month. The fungal spores of Trichophyton spp., and Microsporum spp. were observed in the samples (skin scrapping) under a microscope using 20% potassium hydroxide solution. All experimental calves were observed after 7 days to know the response of the treatment. On the basis of visual observation, the result was recorded on day 14. All experimental calves were observed after 7 days to know the response of the treatment. On the basis of visual observation, the result was recorded on day 14. Calves in the control group remain same. Calves suffering from chronic dermatomycosis or dermatophytosis (ringworm) can be treated with topical antifungal ointment, griseofulvin tablet, streptomycin-penicillin injection, antihistaminic injection and vitamin AD3E injection as per dosages used in this experiment. If the case is acute, topical antifungal ointment and griseofulvin tablet may be recommended as treatment measures. Vitamin AD3E may or may not be used in this case.

Objectives:

To find out the best and most effective treatment approach of ringworm in RCC calves.

Methodology:

Sampling: A total number of 20 skin scrap and broken hair samples were collected by sterile instruments from the margin of lesions of dairy cattle RCC calves suspected to dermatophytosis. Then, the samples were taken to the laboratory for further examinations. Microscopic examination: Direct microscopic examination was performed. After treating with 20% potassium hydroxide solution, the samples were examined under light microscope. Culture: Samples were cultured in growth medium and growth of fungus was observed after three days. Animals and treatment: A total of 20 calves of Red Chittagong Cattle (RCC) were selected for the trial. One calf had acute dermatomycosis and the rest had chronic ones. All the experimental calves were divided into five groups namely – T₀, T₁, T₂, T₃ and T₄. T0 group was kept as control and T₁, T₂, T₃ and T₄ groups were allowed for treatment by using Grisovin® tablet, SP- vet® injection, Astavet® injection and VITA-ADE® injection for T₁; Vermic® injection, SP- vet® injection, Astavet® injection and VITA-ADE® injection for T₂; Dermin® ointment (topical antifungal ointment), Grisovin® tablet (systemic antifungal tablet), SP vet® injection (antibiotic injection), Astavet® injection(antihistaminic injection) and VITA-ADE® injection (vitamin A, D3, E injection) for T3; Dermin® ointment, Vermic® injection, SP vet® injection, Astavet® injection and VITA-ADE® injection for T₄. Dermin® ointment (benzoic acid 6% and salicylic acid 3%) was applied topically twice daily. Grisovin® tablet (griseofulvin) was administered@ 10 mg/kg body weight orally twice daily for 7 days. Vermic® injection (ivermectin) @1 ml/50 kg body weight was injected subcutaneously twice with 7 days interval. SP-vet® inj. (streptomycin-penicillin) @ 1 ml/10 kg body weight was injected intramuscularly once daily for 7 days. Astavet® injection (pheniramine maleate) @ 1 ml/10 kg body weight was injected intramuscularly once daily for 7 days. VITA-ADE® injection @ 1 ml/10 kg body weight was injected intramuscularly three times with 3 days interval. There were four calves in each group as replications. During trial the average age and bodyweight of the animals were 45 days and 25 kg respectively. The experiment was carried out during March-April/2011. The duration of the experiment was about one month. Observation and data recording: All experimental calves were observed daily after 7 days to know the response of the treatment. On the basis of visual observation, the result was recorded on day 14.

Achievement/Findings:

The present study suggests that RCC calves suffering from chronic dermatomycosis or dermatophytosis (ringworm) should be treated with topical antifungal ointment, griseofulvin tablet, streptomycin-penicillin injection, antihistaminic injection and vitamin AD3E injection as per dosages used in this experiment. If the case is acute, topical antifungal ointment and griseofulvin tablet may be recommended as treatment measures. Vitamin AD3E may or may not be used in this case.
