to improve our understanding of helicobacter  infection in cats and to determine whether they are reservoirs for h. pylori  and sources of zoonotic transmission to humans, we selected cats as an experimental animal model for gastric colonization by h. pylori. sixteen stray cats underwent helicobacter  eradication treatment followed by three consecutive oral inoculations of a cocktail of human h...

Plant growth promoting rhizobacteria (PGPR) have gained worldwide importance and acceptance for agricultural benefits. This is due to the emerging demand for dependence diminishing of synthetic chemical products, to the growing M. do Vale Barreto Figueiredo (*) National Research and Technological Development, Brazil Agronomical Institute of Pernambuco, IPA/CARHP, 1371, Gen. San Martin Avenue, R...

Leukotoxin (Ltx) is a prominent virulence factor produced by Aggregatibacter actinomycetemcomitans, an oral microorganism highly associated with aggressive periodontitis. Ltx compromises host responsiveness by altering the viability of neutrophils, lymphocytes, and macrophages. Previously, we developed a Rhesus (Rh) monkey colonization model designed to determine the effect of virulence gene mu...

UNLABELLED Pseudomonas aeruginosa is a ubiquitous microorganism and the most common Gram-negative bacterium associated with nosocomial pneumonia, which is a leading cause of mortality among critically ill patients. Although many virulence factors have been identified in this pathogen, little is known about the bacterial components required to initiate infection in the host. Here, we identified ...

but also their quality of life and their families. This paper reviewed the effectiveness of various preventive measures, categorized as primary, secondary and tertiary prevention. Primary prevention includes oral health education, tooth-brushing with fluoridated toothpaste, water fluoridation, fluoridated milk, and dietary control. Systematic reviews showed that effectiveness of simple health e...

BACKGROUND Sugarcane is one of the most important crops in Brazil, mainly because of its use in biofuel production. Recent studies have sought to determine the role of sugarcane endophytic microbial diversity in microorganism-plant interactions, and their biotechnological potential. Epicoccum nigrum is an important sugarcane endophytic fungus that has been associated with the biological control...

Background and Aims: Nasal Colonization with Methicillin Resistant Staphylococcus aureus (MRSA) is known as an important risk factor in the development of dangerous infections. Materials and Methods: The present study seeks to investigate the prevalence of MRSA nasal colonization among the preschool and school children under 14 in Urmia. To do so, specimens for culture were obtained fro...

The Brownian dynamics of a single microorganism coupled by chemotaxis to a diffusing concentration field that is secreted by the microorganism itself is studied by computer simulations in spatial dimensions d=1,2,3 . Both cases of a chemoattractant and a chemorepellent are discussed. For a chemoattractant, we find a transient dynamical arrest until the microorganism diffuses for long times. For...
