A case of myopericarditis associated to Campylobacter jejuni infection in the southern hemisphere BJID
Fica,Alberto; Seelmann,Daniela; Porte,Lorena; Eugenin,Daniela; Gallardo,Ricardo.
Myopericarditis is an infrequent complication of acute diarrheal illness due to Campylobacter jejuni, and it has been mainly reported in developed nations. The first case detected in Chile - an upper-middle income country -, that is coincidental with the increasing importance of acute gastroenteritis associated to this pathogen, is described. Recognition of this agent in stools requires special laboratory techniques not widely available, and it was suspected when a young patient presented with acute diarrhea, fever, and chest pain combined with electrocardiogram (EKG) abnormalities and elevated myocardial enzymes. C. jejuni myopericarditis can easily be suspected but its detection requires dedicated laboratory techniques.

Campylobacter Jejuni Increases Transcribed Il-1 B and Causes Morphometric Changes in the Ileal Enterocytes of Chickens Rev. Bras. Ciênc. Avic.
Fonseca,BB; Ferreira Júnior,A; Santos,JP dos; Coelho,LR; Rossi,DA; Melo,RT; Mendonça,EP; Araújo,TG; Alves,RN; Beletti,ME.
Abstract Campylobacteriosis is a worldwide foodborne zoonosis disease caused by Campylobacter jejuni. This microorganism is considered a commensal bacterium in chicken hosts. C. jejuni produces epithelial cell modifications and induces a cytokine gene transcription innate immunity repertoire. In the present study, we describe the invasiveness, morphological cellular modifications, and transcript level expressions of innate immune cytokines from C. jejuni-inoculated chicken ileum explants. C. jejuni was internalized by epithelial ileum cells at 15 minutes postinoculation (p.i.) and was detected intracellularly for 4hs (p.i.). Inoculated explants displayed significant increases in cell height. C. jejuni induced a significant elevation of Transforming Growth...

Comparative analysis of cultural isolation and PCR based assay for detection of Campylobacter jejuni in food and faecal samples BJM
Singh,Harkanwaldeep; Rathore,R.S; Singh,Satparkash; Cheema,Pawanjit Singh.
In the present study, the efficacy of polymerase chain reaction (PCR) based on mapA gene of C. jejuni was tested for detection of Campylobacter jejuni in naturally infected as well as spiked faecal and food samples of human and animal origin. Simultaneously, all the samples were subjected to the cultural isolation of organism and biochemical characterization. The positive samples resulted in the amplification of a DNA fragment of size ~589 bp in PCR assay whereas the absence of such amplicon in DNA extracted from E. coli, Listeria, Salmonella and Staphylococcus confirmed the specificity of the primers. Of randomly collected 143 faecal samples comprising human diarrheic stools (43), cattle diarrheic faeces (48) and poultry faecal swabs (52) only 4, 3 and 8,...

Scarcelli,Eliana; Costa,Elizabeth Oliveira da; Genovez,Margareth Élide; Cardoso,Maristela Vasconcellos; Bach,Erna Elizabeth; Torres,Ana Paula.
Electrophoretic protein profiles of Campylobacter jejuni subsp. jejuni strains isolated from feces of seven animal species, including man, were compared. Fourteen strains (two from each species) plus two human strains and the reference one, were ruptured by ultrasound and their total soluble proteins were analyzed by SDS-PAGE technique in a 12% polyacrylamide gel with computerized densitometric reading by the molecular analyst software. All the strains had bands in common that correspond to 45 and 66 Kda molecular weight. The disagreement corresponded to a 97 to 200 Kda molecular weight region. From the 17 strains, 13 (76.5%), were classified as biotype I, three (17.6%) as biotype II and one (5.8%) as biotype III. Since protein extracts were obtained from...

Implantation et survie de Campylobacter jejuni/coli chez la moule Mytilus edulis ArchiMer
Minet, Jacques; Sauvager, F; Cormier, M.
Illnesses due to marine bivalvia consumption are mostly associated with viruses as causative agents. In more than the half of cases, this agent remains unidentifies, nevertheless. So far as bacteria are concerned, Salmonella are found firstly. Campylobacters represent a major cause of gastrointestinal disease, with Salmonella, among humans. Whether campylobacteriosis may be acquired from shellfishes remains unclear. We undertook to comparatively appreciate the survival of Campylobacter jejuni/coli and Salmonella typhimurium in seawater and contaminated mussels. Bacterial enumerations where performes using microbial cultures and specific (with immunofluorescence) direct viable counts (of substrate responsive bacteria). During laboratory contamination...

Prevalence of virulence genes in strains of Campylobacter jejuni isolated from human, bovine and broiler BJM
González-Hein,Gisela; Huaracán,Bernardo; García,Patricia; Figueroa,Guillermo.
Campylobacter jejuni isolates of different origins (bovine, broiler meat, human) were screened by polymerase chain reaction for the presence of 4 genes cdtB, cst-II, ggt, and virB11, previously linked to virulence such as adherence, invasion, colonization, molecular mimicry, and cytotoxin production. In addition, the isolates were screened for the presence of the global gene regulator csrA linked to oxidative stress responses, biofilms formation, and cell adhesion. All the C. jejuni isolates were positive for cdtB gene. The csrA gene was detected in 100% and 92% of C. jejuni isolates from human and animal origin and the virB11 gene was detected in 7.3% and 3.6% isolates from chicken and human respectively. All isolates from bovine were negative for the...

Salmonelosis y campilobacteriosis, las zoonosis emergentes de mayor expansión en el mundo Veterinaria México
Gutiérrez Castillo,Adriana del Carmen; Paasch Martínez,Leopoldo Henri; Calderón Apodaca,Norma Leticia.
En la actualidad, la salmonelosis y la campilobacteriosis son las zoonosis de mayor prevalencia en países desarrollados, debido a la contaminación de alimentos de origen animal. La propagación de Salmonella enterica serotipo Enteritidis y Salmonella enterica serotipo Typhimurium va en aumento a partir de la segunda mitad del siglo XX, cuando ocurrieron dos cambios mundiales en la epidemiología de la salmonelosis: el surgimiento de infecciones en humanos por Salmonella Enteritidis, y la múltiple resistencia a los antibióticos de cepas de Salmonella Typhimurium. La mayoría de los análisis retrospectivos sugieren que existe relación epidemiológica entre las aves y los humanos: La modernización de la avicultura y las exportaciones de aves progenitoras son de...
