AIM This study aimed to detect putative virulence genes in Arcobacter species of animal and human origin. MATERIALS AND METHODS A total of 41 Arcobacter isolates (16 Arcobacter butzleri, 13 Arcobacter cryaerophilus, and 12 Arcobacter skirrowii) isolated from diverse sources such as fecal swabs of livestock (21), raw foods of animal origin (13), and human stool samples (7) were subjected to a ...

The major route of cadmium (Cd) intake by non-smokers is through food ingestion. Cd is a non-essential metal absorbed through one or more transporters of essential metal ions. Expression of these transporters is affected by nutritional status. To investigate the risk factors for Cd toxicity, the effects of deficiency of essential metals on hepatic and renal accumulation of Cd were studied in mi...

This paper describes CADFtest, a R (R Development Core Team 2008) package for testing for the presence of a unit root in a time series using the Covariate Augmented Dickey-Fuller (CADF) test proposed in Hansen (1995). The procedures presented here are user friendly, allow fully automatic model specification, and allow computation of the asymptotic p-values of the test.

materials and methods in silico analysis of the cadf gene was carried out by several software and available online tools. a duplex pcr optimized with specific primers was used for detection and differentiation of both species. to evaluate specificity and sensitivity of the test, a panel of different campylobacter spp. together with several intestinal bacterial pathogens was tested. the limit of...

This introduction to the CADFtest package is a (slightly) modified version of Lupi (2009), published in the Journal of Statistical Software. CADFtest is an R package for testing for the presence of a unit root in a time series using the Covariate Augmented Dickey-Fuller (CADF) test proposed in Hansen (1995b). The procedures presented here are user friendly, allow fully automatic model specifica...

Badania dotyczyły określenia u bakterii Campylobacter spp. częstotliwości występowania wybranych genów wirulencji (cadF, flaA, iam) oraz odpowiedzialnych za powstawanie cytotoksyny CDT (cdtA, cdtB, cdtC). Obiekt badawczy stanowiło 100 próbek kału pobranych od ogierów nie wykazujących objawów kampylobakteriozy. Obecność z rodzaju stwierdzono 25 osobników (25%). Zastosowane w badaniach techniki b...

From 300 stool samples, 58 Campylobacter strains were isolated by standard microbiological and biochemical methods. Of these, 40 strains were identified as Campylobacter jejuni and 5 as Campylobacter coli. The presence of flaA (100%), cadF (100%), racR (100%), dnaJ (100%), pldA (100%), ciaB (95%), virB11 (0%), ceuE (82.5%), cdtA (97.5%), cdtB (97.5%), cdtC (97.5%), and wlaN (7.5%) genes was det...

conclusions this study provides initial data on the prevalence and distribution of the flaa, cadf, ciab, cdtb, cgtb, docc and wlan genes in c. jejuni. background campylobacter jejuni (c. jejuni) is a major cause of human diarrheal disease. objectives this study was conducted to determine the prevalence of different pathogenic genes in isolates recovered from human stool samples in rosario, arge...
