Draft Genome Sequence of Enterococcus casseliflavus PAVET15 Obtained from the Oviduct Infection of the Cattle Tick (Rhipicephalus microplus) in Jiutepec, Morelos, Mexico.

Enterococcus spp. are Gram-positive lactic acid-producing bacteria found in the intestinal tracts of animals, like mammals, birds, and arthropods. Enterococcus spp. may cause oportunistic infections in vertebrate and invertebrate hosts. We report here the draft genome sequence of Enterococcus casseliflavus PAVET15 containing 3,722,480 bp, with 80 contigs, an N50 of 179,476 bp, and 41.93% G+C content.

Complete Genome Sequence of Paenibacillus larvae MEX14, Isolated from Honey Bee Larvae from the Xochimilco Quarter in Mexico City.

Paenibacillus larvae strain MEX14 is a facultative anaerobic endospore-forming bacterium that infects Apis mellifera larvae. Strain MEX14 was isolated from domestic bee larvae collected in a backyard in Mexico City. The estimated genome size was determined to be 4.18 Mb, and it harbors 4,806 protein coding genes (CDSs).

Draft Genome Sequence of Bacillus amyloliquefaciens JJC33M, Isolated from Sugarcane Soils in the Papaloapan Region, Mexico.

Bacillus amyloliquefaciens strain JJC33M is a bacterium that produces α-amylase (EC 3.2.1.1) and was isolated from sugarcane soil. Its estimated genome size is 3.96 Mb, and it harbors 4,048 coding genes (CDSs).

Potentially pathogenic nontuberculous mycobacteria found in aquatic systems. Analysis from a reclaimed water and water distribution system in Mexico City.

We investigated the presence of nontuberculous mycobacteria (NTM) in three Mexican aquatic systems to evaluate the prevalence with the distribution of NTM species. Key physicochemical parameters of the water samples were determined to find correlations with the species' distributions. We used multilocus sequence analysis (MLSA) based on hsp65, rpoB, and 16S rRNA fragments to determine their taxonomic affiliations. NTM were recovered from water distribution systems and reclaimed water from the Mexico City Metropolitan Area (MCMA). The isolated species were associated with a temperature of 21°C and pH >7.7. The phylogenetic analysis showed that eight of the 14 different NTM strains were unambiguously classifiable: Mycobacterium peregrinum, M. nonchromogenicum (2), M. smegmatis (2), M. fortuitum, M. avium ssp. hominissuis, M. arupense, M. gordonae, and M. chitae. One strain was tentatively identified as M. mantenni/ scrofulaceum and another strain was related to M. porcinum/M. septicum. All NTM species identified in the water distribution system were also detected in the reclaimed water, but some species from the reclaimed water were not found in the water distribution systems. Two of the identified species found in the reclaimed water, M. avium and M. fortuitum, are considered important human opportunistic pathogens.
