Vertical slab electrophoresis in polyacrylamide gels was used to monitor changes in lactate dehydrogenase (LDH) isozymes in plasma of white rats during bacterial infection and endotoxin poisoning. Peritoneal infection with Francisella tularensis and Salmonella typhimurium and administration of S. typhimurium endotoxin stimulated significant increases in plasma LDH-5. Rates of change in enzyme a...
Bacterial infection often follows virus infection due to pulmonary interferon-γ (IFN-γ) production during virus infection, which down-regulates macrophage phagocytosis. The molecular mechanisms for this process are still poorly understood. In the present study, IFN-γ treatment significantly inhibited the ability of mouse macrophages to phagocytize nonopsonized chicken red blood cells (cRBCs), b...
To analyze the role of interleukin-10 (IL-10) in bacterial cerebral infections, we studied cerebral listeriosis in IL-10-deficient (IL-10(-/-)) and wild-type (WT) mice, the latter of which express high levels of IL-10 in both primary and secondary cerebral listeriosis. IL-10(-/-) mice succumbed to primary as well as secondary listeriosis, whereas WT mice were significantly protected from second...
BACKGROUND A novel avian-origin influenza A (H7N9) virus emerged and spread among humans in Eastern China in 2013. Prophylactic treatment with antibiotics and probiotics for secondary infection is as important as antiviral treatment. This study aims to assess the ability of probiotic treatment to restore internal homeostasis under antibiotic pressure and to reduce/ameliorate the risk of seconda...
OBJECTIVES To evaluate the efficacy of oral linezolid, with or without rifampicin, on valve vegetations and secondary foci of infection compared with vancomycin, in the absence or presence of rifampicin, in experimental endocarditis caused by methicillin-resistant Staphylococcus aureus. METHODS Treatment groups were controls (n = 16), linezolid (n = 15), vancomycin (n = 15), linezolid and rif...
Staphylococcus aureus is a significant cause of hospital and community acquired pneumonia and causes secondary infection after influenza A. Recently, patients with hyper-IgE syndrome, who often present with S. aureus infections of the lung and skin, were found to have mutations in STAT3, required for Th17 immunity, suggesting a potential critical role for Th17 cells in S. aureus pneumonia. Inde...
INTRODUCTION Identification of bacterial infections is crucial if treatment is to be initiated early and antibiotics used rationally. The primary objective of this study was to test the efficiency of procalcitonin (PCT) in identifying bacterial/parasitic episodes among febrile adult patients presenting to an emergency department. Secondary objectives were to identify clinical or biological vari...
Is an antibiotic needed? Many diseases are not a result of bacterial infection and, especially when not severe, do not need antibiotics to manage them. Relevant examples include mild calf scours and outbreaks of coughing without other signs among growing cattle. Even in more severe cases of scour and pneumonia, the effect of antibiotics may be to protect the animal from secondary infection rath...
the effects of dietary supplementation of garlic (allium sativum)extract on the growth and disease resistance of african catfish, clarias gariepinus was evaluated. also in-vitro evaluation of susceptibility of fish-borne multidrug resistant (mdr) pathogenic bacteria to aqueous extract of garlic was done. aqueous garlic extract exhibited inhibitory activity against mdr bacteria and the degree of...
BACKGROUND Human Rhinovirus (HRV) is responsible for the majority of common colds and is frequently accompanied by secondary bacterial infections through poorly understood mechanisms. We investigated the effects of experimental human HRV serotype 16 infection on the upper respiratory tract microbiota. METHODS Six healthy volunteers were infected with HRV16. We performed 16S ribosomal RNA-targ...
