Mycoplasma spermatophilum

Mycoplasma spermatophilum is a species of bacteria in the genus Mycoplasma. This genus of bacteria lacks a cell wall around their cell membrane.[1] Without a cell wall, they are unaffected by many common antibiotics such as penicillin or other beta-lactam antibiotics that target cell wall synthesis. Mycoplasma are the smallest bacterial cells yet discovered,[2] can survive without oxygen and are typically about 0. 1  µm in diameter.

This mycoplasma species was originally isolated from human spermatozoa and a human cervix. It has been rare in humans because it was recovered from only 1 to 2% of the samples examined in two surveys. These initial samples were collected at a fertility clinic where it was noted that either eggs did not become fertilized with infected sperm or fertilized eggs did not implant in in vitro fertilization procedures.[3][4][5] The genome of this species has been partially sequenced.[6]

The type strain is AH159 = ATCC 49695 = CIP 105549 = NCTC 11720.[7]
