The association of infantile diarrhoea with the occurrence of Candida
species and their different morphological cell forms (pseudohyphae and
/or blastospores) in faeces was studied in children of 0-15 months in
a developing community (Lahore, Pakistan) where malnutrition is preval
ent. Stool samples from 119 patients admitted to the Diarrhoea Treatme
nt Unit, Department of Pediatrics, King Edward Medical College, and 46
healthy children were investigated for yeasts, bacteria, viruses and
parasites. Salmonella and enteropathogenic Escherichia coli were seen
in 13 (11%) each of the cases while Candida was the most frequent micr
o-organism, grown in cultures from 38 (32%) of the diarrhoea cases. C.
tropicalis dominated (19%) over C. albicans (6%) and C. parapsilosis
(3%). However, in a great number of cases (23, equals 19%), Candida di
d not grow in cultures but blastospores and/or pseudohyphae were seen
on microscopical examination. Other Candida species and yeasts were re
latively more common in the control group. Candida albicans, C. tropic
alis and C. parapsilosis were the only identified agents in 23 of the
cases (19%). The characteristic clinical findings in children with Can
dida as the only identified pathogen were malnutrition (69%), age less
than 8 months (90%), and microscopically identified pseudohyphae in f
aecal smears (71%).
