Трихофития крупного рогатого скота, вызванная Trichophyton verrucosum, на фермах в Италии, и передача возбудителя человеку

cattle_trichophytosis

verrucosum — наиболее распространенный возбудитель дерматофитозов (стригущего лишая) среди крупного рогатого скота. Изучена распространенность данного микоза у КРС, а также заболеваемость людей, работающих на животноводческих фермах.

Trichophyton verrucosum is the most common ringworm agent in cattle. Epidemiology of cattle dermatophytoses in Central Italy is not clear. Its diffusion among cattle and herdsmen was investigated in 20 Umbrian farms, Central Italy. Hairs and scales were taken from 395 animals and 31 workers.

Typical ringworm was present in 71.7% of cattle under 6 months and in 11% of animals over 6 months. T. verrucosum was isolated from 98.9% of symptomatic heads and was the most prevalent dermatophyte in all herds investigated (isolated in 18 of the 20 farms). T. mentagrophytes var. mentagrophytes was found in 16 symptomatic and in eight asymptomatic young animals.

Prevalence of asymptomatic carriers of both species was significantly higher in young heads (21.1% vs. 8.1%) and the age below 6 months was the only statistically significant risk factor associated with dermatophytosis.

Распространенность Trichophyton verrucosum среди людей

About the workers, all the 14 me   n with lesions were positive for T. verrucosum; copresence of T. verrucosum and gypseum was noticed in one case. Results indicate a high diffusion of T. verrucosum among both animals and humans in Umbrian farms and confirm the dermatophyte infection as a public health problem. Periodic epidemiological surveys, treatment of sick livestock and workers, cleaning/sanitisation of herds and vaccination programmes may be useful in controlling the infection.

  1. Well, cattle trichophytosis is easily transmittable to humans. Dermatophytic fungi are really «public health problem», and the animals are the main source of dermatophytic infection for humans…
