Název v původním jazyce

Potential risk of Mycobacterium avium subspecies paratuberculosis spread by syrphid flies in infected cattle farms

Popis výsledku v původním jazyce

The syrphid Eristalis tenax may be found around dung storage pits at cattle farms. The purpose of this study was to investigate the occurrence of M.a.paratuberculosis (MAP) in 1044 E.tenax samples, as well as dung from 9 farms. M.fortuitum was isolatedfrom 1 larva from the vicinity of 3 paratuberculosis-free herds of cattle. MAP was isolated from 111 of E.tenax larvae collected from 2 of 7 farms known to be infected with MAP. Mycobacteria were not isolated from any of the 340 pupae, 41 adults of 78samples of exoskeletal exuviae. MAP isolates from E.tenax larvae were of the IS900 RFLP type B-C1, identical to that detected in faecal samples from cattle herds infected with paratuberculosis. Larvae artificially infected with mycobacteria of IS900 RFLPtypeB-C9 did not contain statistically more CFU of identical IS900 RFLP type B-C9 in the intestinal tract and internal organs than on the body surface. These results show that MAP can survive in the intestinal tract and internal organs of E.te
