Fig. 2From: Detection of Rickettsia spp. in Rhipicephalus sanguineus (sensu lato) collected from free-roaming dogs in Coahuila state, northern MexicoPhylogenetic analysis of Rickettsia spp. identified in Mexico. Maximum likelihood phylogenetic trees were inferred using 23S-5S rRNA ITS (a) and ompA sequences (b) of Rickettsia spp. identified in this study (asterisks) and other bacteria of the order Rickettsiales. The 23S-5S rRNA ITS and ompA sequences of Mexico clustered with R. rickettsii and R. rhipicephali reference sequences. Reliability of internal branches was assessed using the bootstrap test (1000 replicates) and only values higher than 60% are shownBack to article page
