The in vitro activities of 12 macrolide compounds against 28 Mycobacterium avium complex strains isolated from patients with acquired immunodeficiency syndrome were determined by the conventional proportion method and by the BACTEC method. Clarithromycin (A-56268; TE-031), a new macrolide compound, was the most active agent tested, inhibiting 90% of strains at an MIC of 4 micrograms/ml by the B...

The present study aimed to determine the incidence of erm(B) and mef(A) among macrolide-resistant S. pneumoniae isolated in children with pneumonia Nghe An province (2019-2021). A total 126 clinical pnemococcal strains from unvaccinated less than 5 years age at Obstetrics Pediatrics Hospital, Vietnam during period Nov 2019 Dec 2021. All were identified using conventional microbiological method,...

Sir, We wish to comment on the paper by Van Kerkhoven et al.,1 to dispel certain misconceptions that may arise from a cursory review of their study. The authors present a 3 year retrospective chart review of patients hospitalized with pneumococcal bacteraemia at a single hospital. Of the 136 patients identified, 14 (10.3%) and 33 (24.3%) had isolates non-susceptible to penicillin and erythromyc...

Abstract Mycoplasma pneumoniae is one of the leading causes community-acquired pneumonia in children and adolescents. Because wide application macrolides clinical treatment, macrolide-resistant M. strains have become increasingly common worldwide. However, molecular mechanisms underlying drug resistance are poorly understood. In present work, we analyzed whole proteomes macrolide-sensitive usin...

BACKGROUND Macrolide resistance in Streptococcus pneumoniae (S. pneumoniae) is a worldwide problem. AIMS The aim of this work was to analyze the phenotypes, genotypes, and clonal relatedness among macrolide-resistant S. pneumoniae strains isolated from various clinical specimens in our hospital. STUDY DESIGN Cross-sectional study. METHODS 80 non-duplicate S. pneumoniae strains were analyz...

Mucus clearance is an important component of the lung's innate defense system. A failure of this system brought on by mucus dehydration is common to both cystic fibrosis (CF) and chronic obstructive pulmonary disease (COPD). Mucus clearance rates are regulated by the volume of airway surface liquid (ASL) and by ciliary beat frequency (CBF). Chronic treatment with macrolide antibiotics is known ...

Background: Antibiotics called macrolide, lincosamide and streptogramin B (MLSB) are being used to treat staphylococci infections. Multiple pathways that impart resistance to MLSB antibiotics have been confirmed to cause clinical failure. The present work aimed to determine the frequency of constitutive and inducible clindamycin resistant among coagulase-negative staphylococci (CoNS) isolates o...
