Carbapenem-resistant Klebsiella pneumoniae (CRKP) is an emerging pathogen with a devastating impact on organ transplant recipients (OTRs). Data describing urinary tract infections (UTIs) due to CRKP, compared to extended-spectrum β-lactamase (ESBL)-producing and susceptible K. pneumoniae, are lacking. We conducted a retrospective cohort study comparing OTRs with a first episode of UTI due to CR...

PCR analysis of 16S-23S internal transcribed spacer (PCR ribotyping) and tRNA intergenic spacer (tDNA-PCR) were evaluated for their effectiveness in identification of clinical strains of Klebsiella pneumoniae and differentiation with related species. For this purpose both methods were applied to forty-three clinical isolates biochemically identified as K. pneumoniae subsp. pneumoniae isolated f...

This study was undertaken to investigate the reported association between Chlamydia pneumoniae and Mycoplasma pneumoniae infection and the expression of asthma-related symptoms. One hundred and eight children with asthma symptoms, aged 9-11 yrs, completed a 13 month longitudinal study. The children maintained a daily diary of respiratory symptoms and peak flow rates. When respiratory symptoms w...

BACKGROUND Mycoplasma Pneumoniae (M. pneumoniae) is a common cause of respiratory tract infections (RTIs), especially in children. Combined diagnostic techniques have provided more reliable information about the epidemiology of infections by this pathogen. The relationship between M. pneumoniae RTIs and climatic conditions is not well documented in the literature. AIMS To study the epidemiolo...

b ackground : one of the main mechanisms of resistance to carbapenems is potential of klebsiella pneumoniae to produce k . pneumoniae carbapenemase (kpc). kpc is an important type of carbapenemase, which can hydrolyze carbapenems and other beta-lactam antibiotics. modified hodge test (mht) and  use  of  boronic  acid  as  a  kpc  inhibitor  are  two  types  of  phenotypic methods, which are use...

background :    klebsiella pneumoniae is among the most common and significant agents of community and hospital-acquired infections. plasmid mediated quinolone resistance (pmqr) was increasingly identified in enterobacteriaceae family worldwide. plasmid-mediated quinolone resistance (pmqr) was first reported in 1998 from a klebsiella pneumoniae isolate in the usa. till date, five qnr proteins h...

background: selective antibody deficiency with normal immunoglobulins (sadni) may be identified as part of distinct primary or secondary immunodeficiency disorders. the clinical manifestations include recurrent, often severe or prolonged, upper or lower respiratory tract infections. objectives: to evaluate sadni in patients with recurrent sinopulmonary infections and its relation to igg subclas...

Attachment of radiolabeled M. pneumoniae to human WiDr cell culture monolayers was dependent on the WiDr cell density and the concentration of M. pneumoniae. Saturation of confluent monolayers grown on 5 mm coverslips was attained with only 40 micrograms of M. pneumoniae protein. Preincubating the WiDr monolayers with unlabeled M. pneumoniae or with a protein-rich extract prepared from M. pneum...
