The gene for a 30-kDa immunodominant antigen, P30, of Mycoplasma agalactiae was cloned from type strain PG2 and expressed in Escherichia coli. P30 is encoded on a monocistronic operon determined by two -10 boxes and a possible -35 region constituting the potential promoter, and a transcription termination site. The gene for the 266-amino-acid protein is preceded by a polypurine-rich region desi...
Here, we report the first whole-genome sequence of Streptococcus agalactiae strain H002, serotype III, isolated in China from a woman 32 weeks pregnant. This sequence represents an important addition to the published genomes and will promote comparative genomic studies of S. agalactiae spp. isolated from diverse regions, particularly when compared with Chinese strains.
The bacterium Mycoplasma agalactiae is responsible for contagious agalactia (CA) in small domestic ruminants, a syndrome listed by the World Organization for Animal Health and responsible for severe damage to the dairy industry. Recently, we frequently isolated this pathogen from lung lesions of ibexes during a mortality episode in the French Alps. This situation was unusual in terms of host sp...

The immunogenicity and efficacy of three inactivated vaccines (A, B, C) prepared with Mycoplasma agalactiae (M. agalactiae) and with different oil-emulsion adjuvants were evaluated in sheep. Twenty-eight animals were used, divided into four groups (a, b, c, d) of seven animals each. Three groups were immunized with the same vaccine, but using different adjuvants, while one group (d) was used as...
Mycoplasma agalactiae is an important pathogen of small ruminants, in which it causes contagious agalactia. It belongs to a large group of "minimal bacteria" with a small genome and reduced metabolic capacities that are dependent on their host for nutrients. Mycoplasma survival thus relies on intimate contact with host cells, but little is known about the factors involved in these interactions ...
Mycoplasmas are minimal bacteria whose genomes barely exceed the smallest amount of information required to sustain autonomous life. Despite this apparent simplicity, several mycoplasmas are successful pathogens of humans and animals, in which they establish intimate interactions with epithelial cells at mucosal surfaces. To identify biological functions mediating mycoplasma interactions with m...
Almost complete (> 96%) 16S rRNA sequences from nine ruminant mycoplasmas have been determined by solid-phase DNA sequencing. Polymorphisms were found in four of the 16S rRNA sequences, which indicated the existence of two different rRNA operons. Seven polymorphisms were found in Mycoplasma agalatiae, three were found in Mycoplasma bovis, one was found in Mycoplasma alkalescens, and one was fou...
