|
|
describe nocardia in terms of bacterial properties and diseases caused.
|
it is partially acid fast due to mycolic acid, but it is not considered acid fast, aerobic. Causes lung disease esp in immunocompromised patients, cutaneous infections (feet is known as mycetoma), can spread to CNS and form brain abscess. diagnose via AFB in lesions, is considered opportunistic. treat with sulfonamides
|
|
describe rhodococcus in terms of diseases caused and bacerial properties.
|
causes invasive pulmonary disease in immunocompromised, is opportunistic and partially acid fast (thats how you diagnose it) common in HIV patients
|
|
describe tropheryma whipplei in terms of disease and bac properties.
|
causes whipple's disease, a chronic and systemic bacterial infection resultin in arthralgia, diarrhea, weight loss, intestinal involvement, hyperpigmentation, and CNS involvement. usually affects middle aged men. diagnose with PCR. It is a human specefic pathogen and an opportunist
