The swabbing and tape-stripping methods have traditionally been used for collecting skin microbiome samples for skin bacterial analysis, although no reports have compared the outcome of these methods for collecting skin bacteria. Our purpose was to show the differences in microbial composition between samples collected using the swabbing and tape-stripping methods, by both the next generation sequencing and culture studies. The skin microbiome was collected by both methods, and the samples were processed for a sequence-based microbiome analysis and culture study...

Background: The skin microbiota plays a key role in the pathogenesis of several skin diseases, but its role in cellulitis remains unknown. We investigated the skin microbiota in patients with cellulitis, studied whether its analysis could help determine the causative pathogen, and explored whether skin microbiota composition was associated with clinical outcomes. Methods: We prospectively included 58 patients hospitalized for cellulitis. Skin swabs obtained from the lesion sites were compared with swabs from identical sites on the contralateral unaffected limbs and with swabs obtained from 19 age- and sex-matched control subjects without cellulitis...

OBJECTIVES: A stool sample is a sample of choice for microbiological testing of enteric pathogens causing diarrhoea, but a rectal swab can be a more practical alternative. A prospective observational study was performed to evaluate the diagnostic performance of flocked rectal swab specimens using the syndromic molecular approach to determine the aetiology of diarrhoea in adults. METHODS: We compared the performance of rectal swabs to stool samples as the gold standard in determining viral, bacterial and protozoal pathogens using real-time multiplex PCR as well as standard stool culture...

Enzootic ovine abortion is caused by Chlamydia abortus and may result in abortion among small ruminants during the last 2-3 weeks of pregnancy. Enzootic abortion is diagnosed by isolation of the agent or detection of its nucleic acid in the products of abortion or vaginal excretions of freshly aborted females. Isolation of chlamydial agents in cell culture is the gold standard, so in the present study this method was employed. Twenty-eight vaginal and conjunctival swab samples were selected from ewes and does that had recently aborted...

Mycoplasma capricolum subspecies capricolum (Mcc) is one of the causative agents of contagious agalactia (CA), which is an important disease in sheep and goats in the Mediterranean and Middle East countries. Mycoplasma agalactiae is the classic agent of CA in sheep and goats. Mycoplasma mycoides subspecies Capri (Mmc), Mycoplasma capricolum subspecies capricolum (Mcc), and Mycoplasma putrefaciens (Mp) produce a clinically similar disease, more often in goats. The aim of the present study was to detect Mcc in sheep flocks in East Azerbaijan Province of Iran...

Contagious agalactia is an infectious syndrome of sheep that is characterized by mastitis with reduction of milk production, arthritis, abortion, and keratoconjunctivitis. The disease is rapidly spread by the contact of the infected animals with the healthy ones. Domestic sheep and goats of both sexes can be infected at an equivalent frequency. Most of the researchers use culture and molecular methods for the isolation and identification of Mycoplasma. Mycoplasma agalactiae is the main cause of the disease in sheep...

PURPOSE: Isolating colonies and obtaining accurate colony counts from bacterial cultures are critical steps for the optimal management of infected patients. The uncertainties in the colony count results from the bacterial cultures were evaluated by verifying the performance of the WASP inoculation system according to the International Organization for Standardization (ISO) 15189 standard. METHODOLOGY: We first (i) evaluated the cross-contamination and precision of the WASP instrument (Copan Diagnostics, Italy) and (ii) established enumeration reading grids for urine, swab, bronchopulmonary specimens (BPSs) and catheter tip cultures...

Objective: Trigeminal neuralgia is defined as a sudden severe shock-like pain within the distribution of the trigeminal nerve. Pain is a subjective experience that is influenced by gender, culture, environment, psychological traits, and genes. Sodium channels and nerve growth factor play important roles in the transmission of nociceptive signals and pain. The aim of this study was to investigate the occurrence of Nav1.7 sodium channel and nerve growth factor receptor TrkA gene polymorphisms (SCN9A/rs6746030 and NTRK1/rs633, respectively) in trigeminal neuralgia patients...

Background: Listeria Right NowTM is a novel, enrichment-free molecular method for detection of Listeria spp. in swab samples from environmental surfaces. The test provides results in real time, indicating the current or recent presence of Listeria spp. in the environment. After sampling, the entire contents of the swab are subject to sample processing, releasing large quantities of target ribosomal RNA molecules into the lysate. A portion of the lysate is then tested using the ANSR® for Listeria isothermal nucleic acid amplification assay...

We report a fatal bacteremia caused by Klebsiella pneumoniae in a 60-70-year-old patient from Brazil. The genomic analysis of three isolates (from blood culture, nasal and anal swabs) showed that the bacteremia was caused by a KPC-2 producing extensively drug-resistant K64-ST11 hypermucousviscous K. pneumoniae (hmKP) harboring several virulence and antimicrobial resistance genes. Although the isolates did not present virulence markers associated with hypervirulent K. pneumoniae (hvKP), they showed invasion and toxicity to epithelial Hep-2 cells; resistance to cell microbicidal mechanisms; and blood and human serum survival, evidencing their pathogenic potential...

BACKGROUND: Traditional skin preparation for shoulder surgery is not specific for Propionibacterium acnes. Topical benzoyl peroxide for 48 h preoperatively has been shown to reduce the bacterial load of P. acnes on the skin. Our aim was to investigate whether skin preparation with a single application of benzoyl peroxide combined with 2% chlorhexidine/alcohol immediately prior to surgery was superior to 2% chlorhexidine/alcohol alone at inhibiting P. acnes. METHODS: We conducted a single-blinded interventional study...
