Bacillus cereus is a gram-positive, spore-forming bacterium possessing an important and historical record as a human-pathogenic bacterium. However, several strains of this species exhibit interesting potential to be used as plant growth-promoting rhizobacteria. Here, we report the draft genome sequence of B. cereus strain CITVM-11.1, which consists of 37 contig sequences, accounting for 5,746,486 bp (with a GC content of 34.8%) and 5,752 predicted protein-coding sequences.

A total of 12 Salmonella isolates belonging to different serovars, viz., Salmonella enterica serovar Enteritidis (n = 4), Salmonella enterica serovar Weltevreden (n = 4), Salmonella enterica serovar Newport (n = 1), Salmonella enterica serovar Litchifield (n = 1), and untypeable strains (n = 2) were isolated from 332 diarrheic fecal samples collected from animals, birds, and humans.

The plasmid-located colistin resistance gene mcr-1 confers low-level resistance to colistin, a last-line antibiotic against multidrug-resistant Gram-negative bacteria. Current CLSI-EUCAST recommendations require the use of a broth microdilution (BMD) method with cation-adjusted Mueller-Hinton (CA-MH) medium for colistin susceptibility testing, but approximately 15% of all MCR-1 producers are classified as sensitive in that broth.

Discrimination of highly pathogenic bacteria, such as Bacillus anthracis, from closely related species based on molecular biological methods is challenging. We applied matrix-assisted laser desorption ionization–time of flight mass spectrometry (MALDI-TOF MS) to a collection of B. anthracis strains and close relatives in order to significantly improve the statistical confidence of identification results for this group of bacteria.

In September 2016, 140 patients with primary symptoms of sore throat and fever were identified in a school dormitory in Osaka, Japan. Epidemiological and laboratory investigations determined that these symptomatic conditions were from a foodborne outbreak of group G streptococcus (GGS), with GGS being isolated from samples from patients, cooks, and foods. The strain of GGS was identified as Streptococcus dysgalactiae subsp. equisimilis of two emm types (stG652.0 and stC36.0).

Salmonella enterica serovar Typhimurium (Salmonella Typhimurium) and its monophasic variant (Salmonella 4,[5],12:i:–) are the major causes of gastroenteritis in both humans and animals. Pulsed-field gel electrophoresis and multilocus variable-number tandem-repeat analysis have been used widely as subtyping methods for these pathogens in molecular epidemiological analyses, but the results do not precisely reflect phylogenetic information.

We aimed to detect the etiological agents of acute diarrhea by a molecular gastrointestinal pathogen test (MGPT) and to assess the impact of MGPT on antimicrobial stewardship programs (ASP). This is a prospective observational study and was conducted between 1 January 2015 and 30 June 2017. We included consequent patients who had acute diarrhea. At the end of 2015, we implemented ASP in acute diarrhea cases and compared the outcomes in the pre-ASP and post-ASP periods.
