Evaluation of CHROMagar™ B. cepacia agar for the detection of Burkholderia cepacia complex species from sputum samples of patients with cystic fibrosis.

Introduction: Burkholderia cepacia complex (BCC) are non-fermenting Gram-negative bacteria that can chronically colonize the lungs of people with cystic fibrosis (pwCF), causing a severe and progressive respiratory failure, post-transplant complications and epidemic outbreaks. Therefore, rapid and accurate identification of these bacteria is relevant for pwCF, in order to facilitate early eradication and prevent chronic colonization. However, BCCs are often quite difficult to detect on culture media as they have a slow growth rate and can be hidden by other fast-growing microorganisms, including Pseudomonas aeruginosa and filamentous fungi.

National Surveillance of Tetracycline, Erythromycin, and Clindamycin Resistance in Invasive : A Retrospective Study of the Situation in Spain, 2007-2020.

Background: This work reports on antimicrobial resistance data for invasive in Spain, collected by the 'Surveillance Program for Invasive Group A ', in 2007-2020.

Methods: typing was determined by sequencing. Susceptibility to penicillin, tetracycline, erythromycin, and clindamycin was detined via the E-test.

Invasive Streptococcus pyogenes disease in Spain: a microbiological and epidemiological study covering the period 2007-2019.

The aim of this study is to present the first nationwide microbiological and epidemiological study of invasive group A Streptococcus (iGAS) disease in Spain. One thousand eight hundred ninety-three iGAS isolates were analyzed over 2007-2019. emm typing was performed by sequencing the gene's variable 5' end, exotoxin genes were identified by PCR, and antimicrobial susceptibility explored via the E test and disk diffusion.

Lactational mastitis caused by Streptococcus lactarius.

Human infections caused by Streptococcus lactarius have not been previously reported. In the present report, we describe a lactational mastitis caused by this organism. The infection occurred in a 28-year-old breast-feeding female, with a 10-days history of moderate pain on the right breast.

Fournier's gangrene caused by Actinomyces funkei, Fusobacterium gonidiaformans and Clostridium hathewayi.

We report the first case of Fournier's gangrene caused by three unusual anaerobic organisms: Actinomyces funkei, Fusobacterium gonidiaformans and Clostridium hathewayi. The infection occurred in a 73-year-old man without typical risk factors for the development of Fournier's gangrene. Clinical outcome was good after prolonged antibiotic treatment and extensive debridement of the perineum.
