Increased Motility in and Changes in Its Virulence, Fitness, and Morphology Following Protein Expression on Ribosomes with Altered RsmA Methylation.

Infection with is the major cause of human gastroenteritis in the United States and Europe, leading to debilitating autoimmune sequelae in many cases. While considerable progress has been made in detailing the infectious cycle of , a full understanding of the molecular mechanisms responsible for virulence remains to be elucidated. Here, we apply a novel approach by modulating protein expression on the pathogen's ribosomes by inactivating a highly conserved rRNA methyltransferase.

Should We Consider Them as a Threat? Antimicrobial Resistance, Virulence Potential and Genetic Diversity of spp. Isolated from Varsovian Dogs.

Campylobacteriosis seems to be a growing problem worldwide. Apart from the most common sources of numerous species, such as poultry and other farm animals, dogs may be an underrated reservoir of this pathogen. Our goal was to establish the frequency of occurrence, antimicrobial resistance, and detection of chosen virulence factor genes in genomes of canine isolates.

Case of necrotic enteritis associated with campylobacteriosis and coccidiosis in an adult Indian peacock (Pavo cristatus).

Background: To date, Campylobacter jejuni has not been found to be pathogenic to peafowl. The available publications show that out of a total of 44 samples tested from peafowl, this bacterium was isolated only in two cases. Eimeria pavonina infestations in the peafowl have been described, but no fatal cases have been reported yet.

Virulence Factors Identified by Modulating Their Synthesis on Ribosomes With Altered rRNA Methylation.

is a major cause of food poisoning worldwide, and remains the main infective agent in gastroenteritis and related intestinal disorders in Europe and the USA. As with all bacterial infections, the stages of adhesion to host tissue, survival in the host and eliciting disease all require the synthesis of proteinaceous virulence factors on the ribosomes of the pathogen. Here, we describe how virulence is attenuated by altering the methylation of its ribosomes to disrupt the composition of its proteome, and how this in turn provides a means of identifying factors that are essential for infection and pathogenesis.

[Mycotic lacrimal canaliculitis--cases report].

Mycotic lacrimal canaliculitis is a rare eye disease. Overuse of antibiotics and steroids in the treatment of eye infections is a very serious risk factor. Initial diagnosis of the mycotic infection may be difficult, thus infection may lasts for months.

[Dacryocystography and dacryoscintigraphy in diagnosis of naso-lacrimal duct obstruction].

Purpose: To find the right diagnostic test through checking the drainage of lacrimal ducts.

Material And Methods: Dacryocystography of lacrimal ducts was performed in 25 patients by using 0.5-1 ml of Lipidiol and conducting X rays in different head positions--3-4 photograph in A-P projection (exposition's parameters 85-90 kV and 12-15 mAs, distance lamp-table: 100-130 cm, Philips Diagnose 93).
