چکیده
Background: Penicillium marneffei infection is the emerging fungal infection in the present day global scenario of HIV pandemic. P. marneffei is a dimorphic fungi with mycelial growth at 37C. Suspicion of P.marneffei infection arises when a immunocompromised individuals especially HIV positive persons present with Molluscum contagiosum like skin lesions. But pulmonary manifestations are not characteristic of P.marneffei infection unless we test the sputum for fungal growth in individuals with low CD4 counts ,we may miss P.marneffei respiratory infection. Material and methods: 100 sputum samples from HIV patients with cough were examined for fungal pathogens by inoculating the samples on SDA and incubated at 28C. The samples with greenish yellow mycelial growth with diffusible red pigment were inoculated on blood agar and SDA and incubates at 37C for conversion to yeast. Results: We isolated two cases of P.marneffei out of 100 samples. The CD4 counts of the cases were 33 and 84. Conclusions: Early diagnosis and treatment reduces the mortality P.marneffei HIV patients. Streszczenie Wstęp: Infekcja Penicillium marneffei jest pojawiającym się zakaŜeniem grzybiczym w obecnym, globalnym scenariuszu pandemii HIV. P. marneffei jest dymorficznym grzybem ze wzrostem grzybni w 37C. Podejrzenie zakaŜenia P.marneffei powstaje, gdy u osób z obniŜoną odpornością, zwłaszcza HIV stwierdzimy obecność mięczaka zakaźnego, jako zmiany skórnej. Płucne objawy nie są charakterystyczne dla infekcji P.marneffei chyba, Ŝe test plwociny jest dodatni (dla wzrostu grzybów) u pacjentów z niskim mianem CD4; moŜemy przeoczyć wówczas infekcję P.marneffei w układzie oddechowym. Materiał i Metody: Zbadano 100 próbek plwociny od pacjentów zakaŜonych HIV z towarzyszącym kaszlem; zbadano patogeny grzybicze poprzez zaszczepienie próbek na SDA i inkubację w temperaturze 28C. Próbki z Ŝółto-zielonkawym wzrostem grzybni z dyfuzyjnym, czerwonym barwnikiem zaszczepiono na krew, agar oraz SDA i inkubowano w temperaturze 37C do konwersji na droŜdŜach. Wyniki: Stwierdziliśmy dwa przypadki izolowanych P. marneffei ze 100 próbek. Miano komórek CD4 w analizowanych przypadkach wynosiło 33 i 84. Wnioski: Wczesne rozpoznanie i leczenie zmniejsza śmiertelność z powodu infekcji P. marneffei u pacjentów z HIV.

Disseminated Penicillium marneffei infections are common AIDS-defining opportunistic infections among persons with human immunodeficiency virus (HIV) infection in northern Thailand. Penicilliosis due to P. marneffei is the third most frequent AIDS-defining infection in this population, after tuberculosis and cryptococcosis. Very little is known about the epidemiology and natural reservoir of P....
