- ... Paenibacillus larvae is the causal agent of American Foulbrood (AFB) disease, the most virulent bacterial disease of honeybee (Apis mellifera L.) brood. Oxytetracycline is the main antibiotic used for prevention and control of AFB. Using the polymerase chain reaction, isolates were screened for the presence of the tetracycline resistance tet(K) and tet(L) determinants. Four isolates (5%), which co ...

- ... The purpose of this study was to characterize, at the molecular level, the Ehrlichia canis strains involved in naturally occurring canine monocytic ehrlichiosis (CME) in Greece, and to investigate if any sequence diversity exists between the 16S rRNA genes of those involved in the mild non-myelosuppressive or the severe myelosuppressive form of CME. To this end, amplification of the ehrlichial 16S ...
