Mycobacterium marinum lymphocutaneous infection
Mycobacterium marinum is a nontuberculous mycobacteria with worldwide distribution that lives in fresh or salt water and is responsible for infections in fish, and sometimes in humans. Human disease consists mainly of cutaneous nodules, but deep structure involvement may also occur. Diagnosis of M. marinum infection remains a challenge, with a considerable time delay between […]

Folate pathway modulation in Rhipicephalus ticks in response to infection
Folate pathways components were demonstrated to be present in RNA-sequencing data obtained from uninfected and pathogen-infected Rhipicephalus ticks. Here, PCR and qPCR allowed the identification of folate-related genes in Rhipicephalus spp. ticks and in the tick cell line IDE8. Genes coding for GTP cyclohydrolase I (gch-I), thymidylate synthase (ts) and 6-pyrovoyltetrahydropterin (ptps) were identified. Differential […]

Correlation among monitoring methods of surface cleaning and disinfection in outpatient facilities
Objectives To evaluate the correlation among microbiological culture, ATP bioluminescence assay, and visual inspection in monitoring the effectiveness of surface cleaning and disinfection in an outpatient facility and determine the ATP bioluminescence cutoff capable of indicating a clean surface regarding microbiological evaluation. Methods Exploratory, cross-sectional, and correlation study consisting of 720 evaluations in five surfaces […]
