Abstract Mycoplasma alkalescens is an arginine-metabolizing mycoplasma which has been found in association with mastitis and arthritis in cattle. Routine bacteriological examination of 17 bronchoalveolar lavage samples from calves with pneumonia in a single herd in Denmark identified M. alkalescens in eight samples. The organism was found as a sole bacterilogical findings in five of the samples as well as in combination with Mannheimia haemolytica Haemophilus somni and Salmonella Dublin. This is the first report of isolation of M. alkalescens in Denmark. Findings Mycoplasma alkalescens is a bovine mycoplasma species which was originally isolated from the nasal cavity of cattle in Australia 1 . Like many other mycoplasmas M. alkalescens is a normal inhabitant of the upper respiratory tract but it has also been associated with disease. M. alka-lescens has mostly been implicated in mastitis in cattle. It has been isolated from bulk tank milk samples as well as from outbreaks and sporadic cases of clinical .
