CHERNAKI-LEFFER, AM et al. Isolation of enteric and litter organisms from Alphitobius diaperinus in brooder chickens houses in west of Parana State, Brazil. Rev. Bras. Cienc. Avic. [online]. 2002, vol.4, n.3, pp.243-247. ISSN 1516-635X.

This study was conducted to determine bacterial species of Enterobacteriaceae in adults of lesser mealworm, A. diaperinus and make the correlation of the bacterial species in the insects and in the litter that infest poultry brooder houses in West of Parana State, Brazil. In the first experiment, the adults were collected in 14 poultry houses. In the second experiment the insects and the litter were collected in 12 poultry houses. The adults were anaesthetized with eter, macerated in sterile saline solution and the litter material was taken off by swab. The enrichment broth was plated on the BHI and in Rappaport-Vassiliadis and Tetrationate. The agar MacConkey, agar Salmonella-Shigella and agar brilliant green was used as plating media for isolating the enterobacteria. The enterobacteria isolated in adults of A. diaperinus were: Proteus Vulgaris, P. mirabilis, Escherichia Coli, Enterobacter spp., E. agglomerans, E. gergoviae, E. sakasakii, Citrobacter Diversus and Klebsiella Pneumoniae. In the litter were found Proteus Vulgaris, P. mirabilis, Escherichia Coli, Enterobacter Agglomerans. There was no Salmonella spp . found in the insect and the litter and P. vulgaris was predominant. E. coli was found in the poultry houses, in the litter and the insects and the bacteria are responsible for dissemination of colibacilose.
