Little is known about the toxin profiles, toxinotypes and variations of toxin Clostridioides difficile C ( tcdC ) in Iranian C. difficile isolates. A total of 818 stool specimens were obtained from outpatients ( n  = 45) and hospitalized patients ( n  = 773) in Tehran, Iran, from 2011 to 2017. The 44 C. difficile isolates were subjected to PCR of toxin C. difficile A ( tcdA ), toxin C. difficile B ( tcdB ), tcdA 3'-end deletion, toxinotyping and sequencing of the tcdC gene. Thirty-eight isolates (86...

We describe the first detection of a KPC-2- and QnrB-producing Enterobacter cloacae from a patient with cystic fibrosis. The bla KPC-2 and qnrB-1 genes were located in a 79.8-kb plasmid. The presence of bla KPC-2 and qnrB-1 genes was determined by PCR and sequencing. Mobilization of plasmid containing bla KPC2 gene was assayed by conjugation.

Corynebacterium ulcerans is an important zoonotic pathogen which is causing diphtheria-like disease in humans globally. In this study, the genomes of three recently isolated C. ulcerans strains, 4940, 2590 and BR-AD 2649, respectively from an asymptomatic carrier, a patient with pharyngitis and a canine host, were sequenced to investigate their virulence potential. A comparative analysis was performed including the published genome sequences of 16 other C. ulcerans isolates. C. ulcerans strains belong to two lineages; 13 strains are grouped together in lineage 1, and six strains comprise lineage 2...

The taxonogenomic approach, including the culturomics techniques, is now currently used to isolate and characterize new bacteria. These approaches notably allowed us to discover six new species of the Actinomyces genus: Actinomyces ihuae strain SD1, Actinomyces bouchesdurhonensis strain Marseille-P2825, Actinomyces urinae strain Marseille-P2225, Actinomyces marseillensis strain Marseille-P2818, Actinomyces mediterranea strain Marseille-P3257 and Actinomyces oralis strain Marseille-P3109. Each is the type strain of the corresponding bacterial species...

Rickettsia felis , the causative agent of flea-borne spotted fever, occurs on all continents except Antarctica, owing to the cosmopolitan distribution of its cat flea vector. In this study, cat fleas were collected in two countries where the occurrence of R. felis was either unknown (Malta) or where accurate prevalence data were lacking (Israel). Altogether 129 fleas were molecularly analysed for the presence of rickettsial DNA. On the basis of three genetic markers, R. felis was identified in 39.5% (15/38) of the cat fleas from Malta...

Aeromonas salmonicida subsp. salmonicida is a pathogen that primarily infects salmonids. A strain of this bacterium, 01-B526, has been used in several studies as a reference. The genomic sequence of this strain is available, but comes from pyrosequencing and is the second most fragmented assembly for this bacterium. We generated its closed genome sequence and found a pitfall in result interpretations associated with low-quality genomic sequences.

REVIEW
M Abdallah, A Balshi
Providencia species are Gram-negative bacteria that belong to the Enterobacteriaceae family. They have intrinsic resistance to colistin and tigecycline, which makes treatment of the multidrug-resistant strains of Providencia challenging. Carbapenem-resistant Providencia species are increasingly reported. In this review, patients' characteristics, resistance mechanisms, treatment and infection control measures of carbapenem-resistant Providencia species in the literature are described.

Some important adverse effects of local and regional anaesthesia including injection-site infection, epidural abscess and meningitis, are usually caused by bacteria such as Staphylococcus aureus and Pseudomonas aeruginosa. These infections can even cause the patient's death in severe cases. In the present study, the antimicrobial activity of tramadol was investigated on S. aureus and P. aeruginosa in BALB/c-sensitive mice. This experimental multigroup research study evaluated the effect of two different concentrations of injectable tramadol (12...

M Sadeqi Nezhad, H Pordeli, N Ghasemi, A Ahani
Siderophores secreted by nonfermentative negative bacilli such as Pseudomonas aeruginosa are capable of increasing rates of resistance to carbapenem antibiotics. Furthermore, the resistance of these isolates to antibiotics has been enhanced by producing siderophores, and their frequencies have erratic patterns. We studied the outbreak of P. aeruginosa strains and their antibiotic patterns in different clinical samples. In this descriptive cross-sectional study, 100 P. aeruginosa samples were isolated from different clinical specimens at the 5th Azar Hospital, Gorgan, Iran, in 2017...

Carbapenem-resistant Enterobacteriaceae is a growing concern worldwide. Klebsiella pneumoniae is an important nosocomial pathogen with a high capacity for nosocomial spread. We described the occurrence of plasmid-encoded KPC-2-harbouring K. pneumoniae isolates recovered from a neurosurgical centre in Argentina. The bla KPC-2 gene was surrounded by IS kpn6 and IS kpn7 .

Clostridium niameyense sp. nov. strain MT5 is the type strain of C. niameyense sp. nov., a new species within the genus Clostridia. C. niameyense is a Gram-positive, anaerobic bacillus. The strain MT5 (= CSUR P1468 = DSMZ 100441), whose genome is described here, was isolated from a faecal sample collected from a patient with anorexia and marasmus living in Nigeria. The genome is 2 542 841 bp long with 27.44% G + C content and consists of six scaffolds.

F Zeroual, H Leulmi, I Bitam, A Benakhla
Using molecular assays, Rickettsia slovaca, the agent of a spotted fever group rickettsiosis resulting in scalp eschar and neck lymphadenopathy after tick bite, was assessed in 92 spleens recovered from 117 wild boars hunted in the far northeast of Algeria. Rickettsia slovaca was detected in 5.4% of tested wild boar spleens. The presence of R. slovaca DNA in boar spleens questions the relationship that may exist between this bacterium and Sus scrofa algira, and its role in human infections.

Coxiella burnetii is a small Gram-negative intracellular bacterium and is the causative agent of Q fever, which is a zoonotic disease with a worldwide distribution. Domesticated ruminants are the main reservoir of the disease, but the bacterium is able to infect a wide range of hosts, including humans, arthropods and invertebrates. Virulence studies of Coxiella strains usually require a suitable animal model. However, mammalian models are costly and are associated with many ethical constraints. An alternative infection model using Galleria mellonella has been used to study the virulence of several bacterial as well as fungal pathogens...
