introduction campylobacter jejuni is a slender, motile, non-spore-forming, helical-shaped, gram-negative bacterium. it is one of the most common causes of human gastroenteritis in the world. the aim of this study was to present a patient with acute lymphocytic leukemia (all), who was infected with campylobacter jejuni. conclusions c. jejuni should be considered in the differential diagnosis as ...

The aim of this study was to determine survival of Campylobacter jejuni (C. jejuni) in chicken meat, chicken skin medallions and chicken liver contaminated with this bacterium at +4 °C and -20 °C, after 24 hours of incubation. The survival of C. jejuni at +4 °C, -20 °C in chicken meat, chicken skin medallions and chicken liver were examined after 24 hours of incubation with C. jejuni. All sampl...

The presence of 11 virulence-associated genes in Campylobacter jejuni isolated from chickens at different stages of their development was examined by PCR. Multiple groups of C. jejuni were colonized in one chicken at the same time. Two hundred thirty one C. jejuni in total were isolated from the same group at four different ages and 12 groups of C. jejuni possessing of 11 virulence-associated g...

The prevalence and antimicrobial susceptibility of Campylobacter jejuni and C. coli strains in healthy, well-nourished children of middle socioeconomic level from Southern Ecuador were determined. Among the 127 children studied, 17 (13.4%) harbored Campylobacter sp. corresponding to C. jejuni (7.1%) and C. coli (6.3%) with a higher concentration of C. jejuni among boys (8.6%) and C. coli (8.8%)...

Invasion in and translocation across enterocytes are major events during Campylobacter jejuni-induced enteritis in humans. C. jejuni in vitro infection of cell monolayers typically results in loss of tight junction integrity, which could contribute to translocation. In the present study, we wanted to investigate whether butyrate is able to confer protection to Caco-2 cells against C. jejuni inv...

Campylobacter jejuni, a gram-negative, invasive organism, is a common cause of food-borne bacterial diarrheal disease. However, the relationship between C. jejuni and the innate immune system is not well described. To better characterize host defense against C. jejuni, we investigated the ability of nitric oxide/reactive nitrogen species to kill two strains of C. jejuni. C. jejuni viability was...

Our current knowledge on Campylobacter jejuni infections in humans has progressively increased over the past few decades. Infection with C. jejuni is the most common cause of bacterial gastroenteritis, sometimes surpassing other infections due to Salmonella, Shigella, and Escherichia coli. Most infections are acquired due to consumption of raw or undercooked poultry, unpasteurized milk, and con...

While both Campylobacter coli and C. jejuni are frequent causes of human campylobacteriosis, a common conclusion of health care professionals and researchers alike is that C. jejuni is the more pathogenic or virulent species. C. jejuni has been shown to be superior in enterotoxin production, suggesting that C. jejuni is more enterotoxigenic, and as such, potentially more virulent than C. coli. ...

The bacterial pathogen Campylobacter jejuni is primarily transmitted via the consumption of contaminated foodstuffs, especially poultry meat. In food processing environments, C. jejuni is required to survive a multitude of stresses and requires the use of specific survival mechanisms, such as biofilms. An initial step in biofilm formation is bacterial attachment to a surface. Here, we investiga...

Campylobacter jejuni is an important zoonotic foodborne pathogen causing acute gastroenteritis in humans. Chickens are often colonized at very high numbers by C. jejuni, up to 10(9) CFU per gram of caecal content, with no detrimental effects on their health. Farm control strategies are being developed to lower the C. jejuni contamination of chicken food products in an effort to reduce human cam...
