Raoultella electrica, a Gram-negative, non-spore-forming, rod-shaped facultative anaerobe, was identified during a regular investigation of bacterial contamination in table eggs in the winter season. A total of 165 hen's eggs were collected in the winter season from 15 different areas of the city of Jaipur, India. Gram-negative Enterobacteriales were isolated on selective and differential media by the conventional plate method and were further identified by several biochemical tests and 16S rRNA gene sequencing...

Methicillin-resistant Staphylococcus aureus (MRSA) is a major nosocomial pathogen. We sought to determine the frequency of the different types of SCCmec in MRSA isolates by performing a cross-sectional study. A total of 72 S. aureus isolates were collected from Imam Khomeini and Golestan hospitals and analysed for MRSA and SCCmec typing by multiplex PCR. The pattern of antibiotic resistance among S. aureus isolates was determined by disc diffusion analysis. Of the 72 S. aureus isolates, 29 (40.27%) were recognized as MRSA...

Culturomics investigates microbial diversity of the human microbiome by combining diversified culture conditions, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and 16S rRNA gene identification. The present study allowed identification of four putative new Clostridium sensu stricto species: 'Clostridium amazonitimonense' strain LF2T, 'Clostridium massilidielmoense' strain MT26T, 'Clostridium nigeriense' strain Marseille-P2414T and 'Clostridium merdae' strain Marseille-P2953T, which we describe using the concept of taxonogenomics...

VanA-type vancomycin-resistant enterococci isolates from bloodstream infections in Cuba were genetically characterized. Enterococcus faecalis isolates were assigned to sequence type (ST) 28, closely related to Eastern Europe, while Enterococcus faecium belonged to ST262, ST656 and ST1349, and showed different genetic profiles.

Rickettsia amblyommatis, formerly named Rickettsia amblyommii and 'Candidatus Rickettsia amblyommii' is an intracellular bacterium belonging to the spotted fever group Rickettsia. It is highly prevalent in Amblyomma americanum and in other Amblyomma spp. throughout the Western Hemisphere. R. amblyommatis has been cultivated in chicken fibroblast, primary embryonated chicken eggs, Vero cells and arthropod-derived cells. Because of the affinity of rickettsiae to invade vascular endothelial cells, we tried to isolate R...

Strain Marseille-P2645T was isolated in a colon sample from a Frenchwoman who underwent a colonoscopy. Bacterial cells were Gram negative, non-spore forming, mobile and strictly anaerobic. The genome of strain Marseille-P2645T is 3 950 441 bp long and contains 3374 protein-coding genes. The DNA G+C content is of 51.66 mol%. Strain Marseille-P2645T exhibited a 92.9% sequence similarity with Bacteroides helcogenes strain P36-108T (GenBank accession no. CP002352), the phylogenetically closest species with standing in nomenclature...

#12
REVIEW
A Garvey, J Powell, B Murphy, N O'Connell, M Imcha, R K Philip
Eikenella corrodens has been noted as a causative organism in both neonatal and perinatal sepsis. Positivity of blood cultures at birth among preterm infants may be influenced by the maternal use of peripartum antimicrobials and a normal C-reactive protein result within the first 24 hours need not always reflect the absence of fetal invasion by the highly pathogenic organisms. For these reasons, supportive and adjunctive approaches such as appropriately collected placental swabs for culture would be of value in optimizing the antimicrobial choice for sick preterm infants during the early neonatal period...

In this study, we report the insertion sequence ISPpu21 in the oprD porin gene of carbapenem-resistant Pseudomonas aeruginosa isolates from burn patients in Tehran, Iran. Antibiotic susceptibility tests for P. aeruginosa isolates were determined. Production of metallo-β-lactamases (MBLs) and carbapenemase was evaluated and the β-lactamase-encoding and aminoglycoside-modifying enzyme genes were investigated by PCR and sequencing methods. The mRNA transcription level of oprD and mex efflux pump genes were evaluated by real-time PCR...

Cholera toxin (CT) is the principal virulence factor of Vibrio cholerae for fatal cholera diarrhoea. Serogroups O1 and O139 harbour CT and are known to be epidemic strains. The remaining serogroups (nonO1/nonO139) are non-toxigenic and may be associated with mild disease. O1 serogroup emerged with a variant of CT known as Haitian cholera toxin (HCT). The HCT strains are hypervirulent and have been associated with severe cholera outbreaks in India, Western Africa and Haiti. Here, we report the presence of HCT (ctxB7) in a nonO1/nonO139 isolate causing persistent diarrhoea...

Strain Marseille-P3237 was isolated from a stool sample of a healthy 35-year-old Congolese pygmy female. This anaerobic, Gram-negative, non-spore-forming and non-motile coccus-shaped bacterium is a member of the order Coriobacteriales. It exhibits a 2 009 306-bp genome with a 65.46 mol% G+C content and is closely related to, but distinct from, members of the Olsenella genus. We propose the creation of the new genus Libanicoccus gen. nov. and of the new species Libanicoccus massiliensis sp. nov.

REVIEW

Shigella spp. and Escherichia coli are closely related; both belong to the family Enterobacteriaceae. Phenotypically, Shigella spp. and E. coli share many common characteristics, yet they have separate entities in epidemiology and clinical disease, which poses a diagnostic challenge. We collated information for the best possible approach to differentiate clinically relevant E. coli from Shigella spp. We found that a molecular approach is required for confirmation. High discriminatory potential is seen with whole genome sequencing analysed for k-mers and single nucleotide polymorphism...

Healthcare-associated items are a common source of acquired infections, and hospital-acquired infections cause significant mortality and morbidity worldwide. Acinetobacter baumannii is the most prevalent infection-causing organism in the hospital environment. Hospital articles and objects are the main sources of infection with the ability to transmit some of the pathogenic microorganisms such as A. baumannii, which is considered a serious problem in therapeutic treatments. In the current study, we isolated A...

"Leucobacter massiliensis" strain 122RC15T sp. nov. is a new species within the genus Leucobacter. The genome of this strain is described here. It was isolated from the pharynx of a 76-year-old Algerian female after travelling from the 2014 Hajj. "Leucobacter massiliensis" is a Gram-positive, aerobic bacillus. Here we describe the features including complete genome and annotation of this strain. The 3 136 406-bp long genome contains 2797 protein-coding genes and 49 RNA genes.

We report the selection in a 15-year-old boy of a multidrug-resistant, extended-spectrum β-lactamase (ESBL)-producing Aeromonas salmonicida after medicinal leech therapy that required an antibiotic prophylaxis based on piperacillin/tazobactam and cotrimoxazole. Whole genome sequencing of the strain indeed revealed 13 antibiotic resistance genes, including the ESBL CTX-M-3 and the unusual β-lactamase SCO-1.
