Transposon mutagenesis of a clinical isolate of Morganella morganii, G1492 (tigecycline MIC of 4 microg/ml), yielded two insertion knockout mutants for which tigecycline MICs were 0.03 microg/ml. Transposon insertions mapped to acrA, which is constitutively overexpressed in G1492, suggesting a role of the AcrAB efflux pump in decreased susceptibility to tigecycline in M. morganii.
This pooled analysis includes 2 phase 3, double-blind trials designed to evaluate the safety and efficacy of tigecycline, versus that of imipenem-cilastatin, in 1642 adults with complicated intra-abdominal infections. Patients were randomized to receive either tigecycline (initial dose of 100 mg, followed by 50 mg intravenously every 12 h) or imipenem-cilastatin (500/500 mg intravenously every ...
In this study, we evaluated the effect of proton pump inhibitors (PPIs) on in vitro antimicrobial activity of tigecycline against several species of clinical pathogens. Clinical non-duplicate isolates of Acinetobacter baumannii, Staphylococcus aureus, Enterococcus faecalis and three species of Enterobacteriaceae (Escherichia coli, Klebsiella pneumonia and Enterobacter cloacae) were collected fr...
We evaluated the effect of tigecycline (50-mg and 200-mg doses) on corrected QT (QTc) intervals and assessed safety and tolerability in a randomized, placebo-controlled, four-period crossover study of 48 (44 male) healthy volunteers aged 22 to 53 years. Fed subjects received tigecycline (50 mg or 200 mg) or placebo in a blinded fashion or an open-label oral dose of moxifloxacin (400 mg) after 1...
BACKGROUND Complicated intra-abdominal infections (cIAI) remain challenging to treat because of their polymicrobial etiology including multi-drug resistant bacteria. The efficacy and safety of tigecycline, an expanded broad-spectrum glycylcycline antibiotic, was compared with imipenem/cilastatin (IMI/CIS) in patients with cIAI. METHODS A prospective, double-blind, multinational trial was cond...
osteomyelitis (bone tissue infection), is a very serious disease affecting many patients by destroying large portions of bone tissue. tigecycline is a recently available antibiotic to overcome bacteria resistance phenomena in bone tissue infections. no information is available regarding its direct effects on bone cells. We have demonstrated deleterious effects of high tigecycline concentrations...
Scrub typhus is a zoonosis caused by Orientia tsutsugamushi (O. tsutsugamushi) occurring mainly in autumn in Korea. The need of new antibiotics has arisen with a report on strains resistant to antibiotics and chronic infection. This study aims to identify susceptibility of tigecycline in-vitro as a new therapeutic option for O. tsutsugamushi. Antibacterial activity of tigecycline against the O....
OBJECTIVES When evaluating the pharmacodynamics of antimicrobials, assumptions are often made relative to their pharmacokinetics. One example of this is applying tissue penetration results of uninfected hosts to those displaying a targeted illness. As tigecycline evolves into a potential treatment option for pneumonia, we determined whether the presence of a lung infection affected the penetrat...
Tigecycline, a member of a new class of antimicrobials (glycylcyclines), was shown to have expanded broad spectrum activity against most commonly encountered species responsible for community and hospital acquired infections, including Gram-positive and Gram-negative multidrug resistant bacterial strains. The aim of the study was to evaluate the activity of tigecycline against resistant bacteri...
BACKGROUND Complicated skin and skin structure infections (cSSSIs) frequently result in hospitalization with significant morbidity and mortality. METHODS In this phase 3b/4 parallel, randomized, open-label, comparative study, 531 subjects with cSSSI received tigecycline (100 mg initial dose, then 50 mg intravenously every 12 hrs) or ampicillin-sulbactam 1.5-3 g IV every 6 hrs or amoxicillin-c...
