Identification and sub-typing of Mycobacterium avium subsp. paratuberculosis and Mycobacterium avium subsp. avium by randomly amplified polymorphic DNA.

A commercially available kit consisting of twenty 10-mer random primers was evaluated to allow selection of a suitable primer that would permit identification and sub-typing of Mycobacterium avium subsp. paratuberculosis and Mycobacterium avium subsp. avium by randomly amplified polymorphic DNA (RAPD).

Reservoir competence of Carcinops pumilio for Salmonella enteritidis (Eubacteriales: Enterobacteriaceae).

The histerid beetle Carcinops pumilio (Erichson) occurs naturally in poultry house manure and is an important predator of house fly eggs and larvae. Because efforts to commercially produce C. pumilio have been unsuccessful, one fly control strategy under consideration is the direct transport of adult C.

Neosporosis-associated bovine abortion in Pennsylvania.
