<prompt> Natural method of horizontal gene transfer among bacteria includes:AElectroporationBTransductionCTransformationDConjugationEMutationBCDACBBCADAB  <response>: ACTINOMYCESMorphologyo Gram positiveo Non motileo Non sporingo Non-acid fasto Non-capsulatedo Filaments that break up into bacillary and coccoid elements.Pathogenesiso Actinomyces are members of normal oral flora and are often cultured from bronchi, GI. tract, and thefemale genital tract.o Actinomycosis in human beings is an endogenous infection.o The critical step in the development of actinomycosis is disruption of mucosal barrier.o Foreign bodies appear to facilitate infection. This association most frequently involves IUCD.Clinical manifestationso Young males 10-30 years are most commonly affectedo Actinomycosis is a chronic granulomatous infection. It is characterized by the development ofindurated swellings, suppuration and the discharge of sulphur granules.
