ব্যাখ্যা
Infections are usually due to a mixture of anaerobes and aerobes in common with the typical flora encountered in the mouth and upper respiratory tract. Isolates of Prevotella melaninogenica, Fusobacterium necrophorum, anaerobic or microaerophilic cocci and Bacteroides fragili may be identified. When suppurative pneumonia or a pulmonary abscess
occurs in a previously healthy lung, the most likely infecting organisms are Staph. aureus or K. pneumoniae. Actinomyces spp. cause chronic suppurative pulmonary infections, which may be associated with poor dental hygiene.

Regarding Paromomycin which is not correct?
ব্যাখ্যা
Paromomycin is an aminoglycoside that is used to treat visceral leishmaniasis and intestinal amoebiasis. It is not significantly absorbed when administered orally, and is therefore given orally for intestinal amoebiasis and by intramuscular injection for leishmaniasis. It showed early promise in the treatment of HIV-associated cryptosporidiosis but subsequent trials have demonstrated that this effect is marginal at best.
