Opportunistic pathogenic fungi isolated from feces of feral pigeons in Mafikeng, North West Province of South Africa.

BACKGROUND AND AIM

Pigeon feces are increasingly being implicated in the spread of bacterial pathogens such as , , , , and . Fungi are rarely investigated except for that has emerged as an important pathogen in old people and immunosuppressed patients. This study investigated fungi in pigeon feces collected from Mafikeng, the North West Province of South Africa.

MATERIALS AND METHODS

Freshly dropped feces were collected and enriched in phosphate-buffered saline overnight at 48°C and then subcultured on Sabouraud's dextrose agar and incubated at 48°C for 2 weeks observing any fungal growth from day 2. The growths were picked up, DNA extracted, and polymerase chain reaction was done using the internal transcribed spacer primers.

RESULTS

Fungi isolated included: (), ( and ), spp., and ( and ). Most of these isolates are known opportunistic pathogens and have been isolated in clinical conditions elsewhere. Other isolates such as , , , , and were not found to be of any human health significance.

CONCLUSION

We, therefore, concluded that the presence of these opportunistic pathogens is a significant human health risk, especially in the face of the HIV/AIDS pandemic that results in immunosuppression.
