profile of fungi, mycoplasma and anaerobic bacteria in non tuberculous bronchopulmonary infections

ABSTRACT

Respiratory secretions were collected from 91 patients with non-tuberculous bronchopulmonary infections by sputum expectoration [38 cases], nebulization [40 cases] and invasive techniques [I.T.], [13 cases]. Before I.T. sputa were collected from patients of the invasive group and studied. So, for all [104] specimens, cultures were done to isolate aerobic, mycoplasma and fungal pathogens. Anaerobic cultures were done only to specimens collected by I.T. [13 specimens]. The most frequently isolated pathogens were Gram negative aerobic and facultatively anaerobic rods [28 cases], Strept pneumoniae [20 cases], Strept pyogenes [19 cases], Staph aureus [18 cases]. Fungi were isolated from 29 cases, mycoplasma pneumoniae were isolated from 7 cases and Branhamella cattarrhalis from 3 cases. Anaerobic bacterial pathogens were isolated from 4 cases out of the 13 cases studies by I.T. The study showed that anerobic bacteria, fungi and mycoplasma constitute a major share in bronchopulmonary pathogens. The study showed also the importance of I.T. in sampling the lower respiratory tract being the only method accepted for anaerobic cultures and giving a less fungal yield [15.4%] than that by expectoration [38.5%], before invasive techniques in the same 13 cases Also, the present series illustrated the clinicoradiological profile of the different pathogens which will help in suggesting the therapeutic strategies in the relevant clinical situations
