Abstract

Mycoplasma species are well known pathogens in avian medicine, especially in poultry. However, several Mycoplasma species have been regularly found in the respiratory tract of birds of prey which seem to be commensals in these bird species. In previous studies, an unknown Mycoplasma species which caused false positive results in a Mycoplasma meleagridis -specific PCR, was isolated from a tracheal swab of a clinically healthy, captive, adult peregrine falcon (Falco peregrinus). The isolate appeared in typical fried-egg-shaped colonies on SP4 agar plates and was dependent on sterol for growth. Acid was produced from glucose, but no arginine or urea was hydrolysed. The temperature range for growth was 28–44 °C, with an optimum at 37 °C. Strain M26 was serologically distinct from all species of the genus Mycoplasma with 16S rRNA gene sequence similarity ≥94 %. Biochemical, serological and molecular biological properties demonstrate that this organism represents a novel species of the genus Mycoplasma , for which the name Mycoplasma hafezii sp. nov. is proposed; the type strain is M26 (NCTC 13928, DSM 27652).
