background and objective: to evaluate extended spectrum betalactamase (esbl) positive strains of klebsiella pneumonia and escherichia coli in positive bacterial cultures. materials and methods: in this analytical cross-sectional study, between march 2006 and march 2007, 170 bacterial isolates including 133 cases of e. coli and 37cases of k. pneumonia were examined. all cases underwent double di...

The bio-materials of four marine mangrove medicinal plants viz., Aegiceras Corniculatum (AGC), Excoecariaagallocha (EA), Rhizophoramucronata (RM) and Xylocarpusgranatum (XG) are extracted with methanol and hexane. These extracts are submitted to the antibacterial activity towards the strains:Bacillus puvuilis, Bacillus subtilis, Bacillus coagulans, Staphylococcus aureus, Bacillus licheniformis,...

BACKGROUND Klebsiella spp. are implicated as a common cause of bacterial pneumonia in horses, but few reports describe clinical presentation and disease progression. HYPOTHESIS/OBJECTIVES To describe the signalment, clinicopathologic data, radiographic and ultrasonographic findings, antimicrobial susceptibility, outcome, and pathologic lesions associated with Klebsiella spp. pneumonia in hors...

antibiotic resistance is a phenomenon in which antibiotic used to treat bacteria becomes useless due to resistance mechanism. increased drug resistance and occurrence of multiple drug resistance in bacteria specificity nosocomial and urinary tract infection bacteria has reduced the possibilities of treating these infectious diseases. efflux pumps are one of the major mechanism of mdr in bacteri...

Klebsiella pneumoniae is a common cause of nosocomial pneumonia. Osteopontin (OPN) is a phosphorylated glycoprotein involved in inflammatory processes, some of which is mediated by CD44. The aim of this study was to determine the role of OPN during K. pneumoniae-induced pneumonia. Wild-type (WT) and OPN knockout (KO) mice were intranasally infected with 10⁴ colony forming units of K. pneumoniae...

Pneumonia presenting at birth or occurring within first 48 hours of life is most commonly caused by E. coli, Streptococci, Klebsiella aerobacter or Enterococci(1). Congenital pneumonia produces intrauterine death in 16-20% of neonates(l). Early diagnosis and adequate treatment can reduce the mortality to a great extent. We report a case of congenital pneumonia caused by Klebsiella pneumoniae wi...

The genus Klebsiella contains Gram negative, capsulated, non-motile bacilli, belonging to the Enterobacteriaceae family (Mackie, 1999). There are five species under this genus, Klebsiella pneumoniae, Klebsiella oxytoca, Klebsiella planticola, Klebsiella terrigena, and Klebsiella ornithinolytica. Amongst them, the most common opportunistic and nosocomial pathogen is Klebsiella pneumoniae causing...

Klebsiella pneumoniae is a Gram-negative human pathogen capable of causing hospital-acquired infections with an increasing risk to human health. The total DNA from four clinically relevant strains was sequenced to >100× coverage, providing high-quality genome assemblies for K. pneumoniae strains ATCC 13883, KP4640, 101488, and 101712.
