OBJECTIVE: To determine the significance of Pneumocystis jirovecii infection in the Kenyan paediatric population. DESIGN: Sixty samples of induced sputum from children aged < or =23 months, half of whom were human immunodeficiency virus (HIV) positive, admitted with severe pneumonia in Nairobi were subjected to immunofluorescent staining for detection of P. jirovecii and microbiological culture. RESULTS: P. jirovecii was detected in 8/60 (13%) as a copathogen with other respiratory pathogens. Five of eight samples with >5 oocysts were from HIV-positive children aged < or =6 months, while equivocally scored samples (< or =5 oocysts) were from HIV-negative children aged >6 months. Klebsiella pneumoniae was significantly recovered in 26/ 60 (43%), followed by Escherichia coli 11/60 (18%) and Staphylococcus aureus 8/60 (13%). Streptococcus pneumoniae, Haemophilus influenzae and Pseudomonas aeruginosa were isolated infrequently. Candida albicans was recovered from 27/60 (45%), while the frequency of C. tropicalis, C. glabrata and C. parapsilosis was 7%, 5% and 3% respectively. Multidrug resistance among E. coli and K. pneumoniae were: sulphamethoxazoletrimethoprim 100% vs. 69%, chloramphenicol 55% vs. 73% and ampicillin 100% vs. 89%. CONCLUSION: Paediatricians in Kenya should be aware of Pneumocystis pneumonia, irrespective of the patient's HIV status.
