Polymicrobial intra-abdominal infections (IAIs) are clinically prevalent and cause significant morbidity and mortality, especially those involving fungi. Our laboratory developed a mouse model of IAI and demonstrated that intraperitoneal inoculation with Candida albicans or other virulent non-albicans Candida (NAC) species plus Staphylococcus aureus resulted in 70 to 80% mortality in 48 to 72 h...

Candida albicans is commonly found in mixed infections with Pseudomonas aeruginosa, especially in the lungs of cystic fibrosis (CF) patients. Both of these opportunistic pathogens are able to form resistant biofilms and frequently infect immunocompromised individuals. The interaction between these two pathogens, which includes physical interaction as well as secreted factors, is mainly antagoni...

Toll-like receptors (TLRs) are important for the activation of innate immune cells upon encounter of microbial pathogens. The present study investigated the potential roles of TLR2, TLR4, and the signaling protein myeloid differentiation factor 88 (MyD88) in polymicrobial septic peritonitis. Whereas both TLR2 and TLR4 were dispensable for host defense against septic peritonitis, MyD88-deficient...

The immunocompromised airways are susceptible to infections caused by a range of pathogens which increases the opportunity for polymicrobial interactions occur. Pseudomonas aeruginosa and Staphylococcus aureus predominant causes pulmonary infection individuals with respiratory disorders such as cystic fibrosis (CF). spore-forming fungus Aspergillus fumigatus, is most frequently isolated P. aeru...

Bacteroidetes are a phylum of Gram-negative bacteria abundant in mammalian-associated polymicrobial communities, where they impact digestion, immunity, and resistance to infection. Despite the extensive competition at high cell density that occurs in these settings, cell contact-dependent mechanisms of interbacterial antagonism, such as the type VI secretion system (T6SS), have not been defined...

We performed a postmarketing surveillance study to determine the efficacy and safety of the oral quinolone antibacterial agent garenoxacin (Geninax(®) Tablets 200 mg) against atypical pneumonia. Between October 2009 and July 2011, patients with community-acquired pneumonia visited 26 facilities in Japan; we collected survey forms from 105 of these patients who were suspected of having atypical ...

Biofilms are microbial communities that inhabit various surfaces and are surrounded by extracellular matrices (ECMs). Clinical microbiologists have shown that the majority of chronic infections are caused by biofilms, following the introduction of the first biofilm infection model by J. W. Costerton and colleagues (J. Lam, R. Chan, K. Lam, and J. W. Costerton, Infect Immun 28:546-556, 1980). Ho...

Mycoplasma ovipneumoniae is a respiratory pathogen that impacts domestic sheep (Ovis aries; DS) and bighorn canadensis; BHS). BHS are reported to be more susceptible than DS developing polymicrobial pneumonia associated with M. infection. Using formalin-fixed paraffin-embedded tissues, we performed retrospective study investigating the pulmonary immune response of infected exhibited robust well...
