Mycobacterial cross contamination during radiometric culturing

Mycobacterial cross contamination during radiometric culturing.

Pseudobacteremias in blood cultures performed on the BACTEC radiometric blood culture system have been reported. We report three cases of cross contamination with Mycobacterium avium that occurred when mycobacteria were cultured with the BACTEC 460 TB system. Malfunction of the needle sterilization heating block was demonstrated.

Blood culture cross contamination associated with a radiometric analyzer.

During a 9-day period in August 1980 in a New Jersey hospital, three pairs of consecutively numbered blood cultures from different patients were identified as positive for the same organism (two pairs of Klebsiella pneumoniae and one pair of group A Streptococcus), for each pair, both cultures were positive in the same atmosphere, both organisms had the same sensitivities, and the second of eac...

Cross contamination of turkey carcasses by Salmonella species during defeathering.

Salmonella present on the feathers of live birds could be a source of contamination to carcass skin during defeathering. In this study, the possibility of transfer of Salmonella from the feathers of live turkeys to carcass tissue during the defeathering process at a commercial turkey processing plant was investigated. The contribution of scald water and the fingers of the picker machines to cro...
