Staphylococcus spp. is a major cause of nosocomial infection and sepsis. However, increasing drug resistance is becoming a challenge to microbiologists. The purpose of this study was to identify and determine antimicrobial resistance phenotypes and drug resistance genes of clinical coagulase-negative staphylococci (CoNS) isolates at Mae Sot Hospital in Tak province, Thailand. A total of 229 CoN...

Colonic myoelectrical activity was recorded during 24 hours in 23 patients with painless diarrhoea and compared with a control group of 10 healthy subjects without digestive functional disorders. Diurnal fasting activity showed no significant difference in the total long spike bursts activity (LSB lasting greater than 7 seconds), but short spike bursts activity (SSB, lasting less than 7 seconds...

HMR 3004 is a new hydrazono ketolide characterized by a 3-keto function instead of the cladinose moiety. The effect of this antimicrobial agent on inducible and constitutive macrolide-lincosamide-streptogramin B (MLSB) resistance was tested in a lacZ reporter system under control of several ermAM-like attenuator variants. For one constitutively resistant Streptococcus agalactiae strain, three i...

BACKGROUND The present analysis focuses on phenotypic and genotypic characterizations of efflux-mediated erythromycin resistance in Streptococcus pneumoniae due to an increase in macrolide resistance in S. pneumoniae worldwide. METHODS We investigated the prevalence of efflux-mediated erythromycin resistance and its relevant genetic elements from 186 specimens of S. pneumonia isolated from cl...

Background and Objectives: This study aimed to assess the psychometric properties of the Persian version of the multiple lifestyle behaviors (MLSB) questionnaire during the COVID-19 outbreak by considering the role of gender and exercise. Methods: This research population included all Iranian men and women in the age range of 18 to 65 years living in Iran in the summer of 2021. The statistical...

Steganography is a technique for the secure transmission of data over the network. In this process, the secret information is transmitted by hiding this behind a signal or image or video. Steganography can be a solution which makes it possible to send news and information without being censored and without the fear of the messages being intercepted and traced back to us. In this process, the se...

The search for a specific rRNA methylase motif led to the identification of the new macrolide, lincosamide, and streptogramin B resistance gene erm(43) in Staphylococcus lentus. An inducible resistance phenotype was demonstrated by cloning and expressing erm(43) and its regulatory region in Staphylococcus aureus. The erm(43) gene was detected in two different DNA fragments, of 6,230 bp and 1,55...

Staphylococci are important causative agents of nosocomial and community acquired infections in skin and soft tissues. Emergence of methicillin resistance in Staphylococci has left us with very few therapeutic alternatives available to treat. The Macrolide – lincosamide Streptogramin B (MLSB) family of antibiotics serves as one such alternative with Clindamycin being preferred agent due to its ...
