<p>Acne vulgaris (acne) is the most common skin disease we see in dermatology practice. Although rare in childhood, severe acne can affect up to 12% of the adolescent population. A chronic disease, it requires both aggressive management and effective maintenance strategies. Oral antibiotics, in combination with topical agents are recommended for treatment, with topical agents being continued as maintenance therapy to minimize resistance and recurrence. However, concerns with systemic side effects have recently resulted in a greater focus on the potential of fixed combination topical therapies to treat severe acne...

OBJECTIVE: To investigate the association of drug resistance of Mycoplasma pneumoniae (MP) with DNA load and genotypes in children with MP pneumonia. METHODS: A total of 230 children who were hospitalized and diagnosed with MP pneumonia between January 2012 and December 2016 were enrolled. Throat swabs were collected from the 230 children, and a rapid drug sensitivity assay was used to determine the sensitivity of clinical isolates of MP to nine commonly used antibacterial agents...

Anaerobic bacteria have pivotal roles in the microbiota of humans and they are significant infectious agents involved in many pathological processes, both in immunocompetent and immunocompromised individuals. Their isolation, cultivation and correct identification differs significantly from the workup of aerobic species, although the use of new technologies (e.g., matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, whole genome sequencing) changed anaerobic diagnostics dramatically...

Diabetic foot infections are a common and serious problem for all health systems worldwide. The aim of this study was to examine the resistance to antibiotics of microorganisms isolated from infected soft tissues of diabetic foot ulcers, using tissue cultures. We included 113 consecutive patients (70 men, 43 women) with a mean age of 66.4 ± 11.2 years and a mean diabetes duration of 14.4 ± 7.6 years presenting with diabetic foot soft tissue infections. Generally, no high antibiotic resistance was observed...

Taher Uddin, Geoffrey Ian McFadden, Christopher Dean Goodman
Malaria parasites contain a relict plastid, the apicoplast, which is considered an excellent drug target due to its bacterial-like ancestry. Numerous parasiticidals have been proposed to target the apicoplast, but few have had their actual targets substantiated. Isopentenyl pyrophosphate (IPP) production is the sole required function of the apicoplast in the blood stage of the parasite life cycle, and IPP supplementation rescues parasites from apicoplast perturbing drugs. Hence, any drug that kills parasites when IPP is supplied in culture must have a non-apicoplast target...

Propionibacterium acnes is a commensal bacterium, which is involved in acne inflammation. An antimicrobial peptide named CEN1HC-Br, which was isolated and characterized form the green sea urchin, has been shown to possess broad-spectrum antibacterial activity. Little is known concerning the potential effects of its antibacterial and anti-inflammatory properties against P. acnes. To examine the potency of CEN1HC-Br in acne treatment, we conducted experiments to analyze the antibacterial and anti-inflammatory activities of CEN1HC-Br both in vitro and in vivo...

Streptococcal toxic shock syndrome (STSS) is a severe invasive infection characterized by the sudden onset of shock, multiorgan failure, and high mortality. Although STSS is mainly caused by Streptococcus pyogenes, group G streptococcus identified as S. dysgalactiae subsp. equisimilis (SDSE) causing STSS has also been reported; however, no study has analyzed >100 isolates of SDSE causing STSS. Therefore, we characterized the emm genotype of 173 SDSE isolates obtained from STSS patients in Japan during 2014-2016 and performed antimicrobial susceptibility testing using the broth microdilution method and emm gene typing...

Group B Streptococcal isolates (n = 235) from the South of Ireland were characterised by serotyping, antimicrobial susceptibility and determination of the phenotypic and genotypic mechanisms of resistance. Resistance to erythromycin and clindamycin was observed in 21·3% and 20·4% of the total population, respectively. The c-MLSB phenotype was the most common phenotype detected (62%), with ermB being the predominant genetic determinant, present in 84% of resistant isolates. The rare L phenotype was observed in 2·9% (n = 7) of isolates, four of which harboured the lsaC gene responsible for clindamycin resistance...

In the last decade there has been a rapid global spread of methicillin-resistant Staphylococcus pseudintermedius (MRSP) clones displaying multidrug resistance in dogs. We investigated prevalence, antimicrobial susceptibility and clonal distribution of MRSP isolated from clinical canine samples between during 2011-2014. Following species identification by nuc PCR, MRSP were confirmed by the presence of mecA and characterized by antimicrobial susceptibility testing, Pulsed Field Gel Electrophoresis (PFGE), SCCmec typing, and Multi-Locus Sequence Typing (MLST) of a few isolates having distinct PFGE profiles...

This study aimed to investigate classical enterotoxin (sea to see) and mecA genes, by polymerase chain reaction (PCR) and anitimicrobial susceptibility, by disc diffusion test of Staphylococcus aureus isolated from minas frescal cheese (MFC). All methicillin resistant S. aureus (MRSA) isolates were investigated for the presence of PVL genes and clonal diversity. Thirty-one S. aureus were isolated from four MFC samples. Seven (22.6%) S. aureus carried mecA gene and two of them carried enterotoxin genes seb/sec and sea/seb...

BACKGROUND: Optimal antibiotic prophylaxis duration in head and neck clean-contaminated free-flap cases is unknown. METHODS: A systematic review/meta-analysis was conducted using PubMed/MEDLINE, Cochrane Library, Web-of-Science, and Scopus databases. RESULTS: Of the 3755 searched articles, 5 articles were included for a total of 861 patients. The recipient surgical site infection risk was significantly higher in patients receiving prophylactic antibiotics for ≤24 hours compared to >24 hours (relative risk [RR] 1...

OBJECTIVES: Until the introduction of fidaxomicin, antimicrobial treatment for Clostridium difficile infection (CDI) was limited to metronidazole and vancomycin. The changing epidemiology of CDI and emergence of epidemic C. difficile PCR ribotype 027 necessitates continued surveillance to identify shifts in antibiotic susceptibility. ClosER, currently the largest pan-European epidemiological study of C. difficile ribotype distribution and antibiotic susceptibility, aimed to undertake antimicrobial resistance surveillance pre- and post-introduction of fidaxomicin...

Ludwig's angina is a diffuse cellulitis in the submandibular, sublingual, and submental spaces, characterized by its propensity to spread rapidly to the surrounding tissues. Early recognition and treatment for Ludwig's angina are of paramount importance due to the myriad of complications that can occur in association with Ludwig's angina. Known complications of Ludwig's angina include carotid arterial rupture or sheath abscess, thrombophlebitis of the internal jugular vein, mediastinitis, empyema, pericardial effusion, osteomyelitis of the mandible, subphrenic abscess, aspiration pneumonia, and pleural effusion...
