The prevalence of Mycoplasma bovis in milk samples submitted to the Israeli National Service for Udder Health and Milk Quality was determined during the period 2004-2014 and the genetic pattern of the obtained isolates was assessed by multilocus sequence typing (MLST). Mycoplasma spp. were identified in 66 herds including M. bovis (n = 60), M. cottewii (n = 3), M. bovigenitalium (n = 2), M. alkalescens (n = 2) and M. yeatsii (n = 1). The proportion of M. bovis infected herds was relatively low (0-0.68%) in 2004-2007, increased to 3.77% during the 2008 outbreak, and ranged from 0.77 to 2.77% during the 2009-2014 period. Since 2008, about eight M. bovis positive dairy herds have been identified in Israel annually, with six of which on average being newly infected. MLST of 57 M. bovis isolates revealed that sequence type 10 was the dominant genotype identified in 60% of the herds. In conclusion, these data show that M. bovis is the main mycoplasmal mastitic pathogen in Israel.
