Literature data indicate an association between the presence of Helicobacter spp. in the liver and the development of hepatocellular carcinoma (HCC). However, the role of H. pylori infections in chronic liver diseases (CLD) remains controversial. The aim of this study was to detect Helicobacter spp. DNA in patients with CLD, and to investigate the host response to the presence of the bacterium ...
Prairie dogs (Cynomys ludovicianus) are used to study the aetiology and prevention of gallstones because of the similarities of prairie dog and human bile gallstone composition. Epidemiological and experimental studies have suggested a connection between infection with Helicobacter species and cholesterol cholelithiasis, cholecystis and gallbladder cancer. Ten of the 34 prairie dogs in this stu...
The genus Helicobacter contains 35 named species and numerous provisionally named species. It is likely that several novel Helicobacter species await discovery. Members of this genus are microaerobic, have a fusiform or curved to spiral rod morphology and are motile by flagella that vary in number and location among different species (Vandamme et al., 1990). All known Helicobacters live in huma...
Helicobacter species have been isolated and cultured from both the gastric and enterohepatic niches of the gastrointestinal tract and are associated with a wide spectrum of diseases. Some members of the enterohepatic Helicobacter species (EHS), which include Helicobacter bilis, Helicobacter hepaticus and Helicobacter pullorum, are associated with chronic inflammatory and proliferative bowel inf...
Antimicrobial Effects of Aqueous and Hydro-Alcoholic Plantago psyllium leaf extracts on the Experimental Infection Helicobacter pylori in a Rat Model
This study examines the use of fecal indicator bacteria (FIB) as a predictor of the presence of Helicobacter spp. A combination of standard culture and molecular techniques were used to detect and quantify FIB, Helicobacter spp. and H. pylori from five North American rivers of different size and with different land use characteristics. Primers designed to amplify genes specific to Helicobacter ...
Bile-tolerant Helicobacter species such as Helicobacter pullorum, Helicobacter bilis, and Helicobacter hepaticus are associated with hepatic disorders in animals and may be involved in the pathogenesis of chronic liver diseases (CLD) in humans. Antibody responses to cell surface proteins of H. pullorum, H. bilis, and H. hepaticus in serum samples from patients with CLD, a randomized population ...
BACKGROUND Polymorphisms in the immune related genes are important in the clinical outcome of Helicobacter pylori infection. Myeloperoxidase -463 G/A polymorphism has been shown to reduce enzyme expression and activity. OBJECTIVE the aim of the present study is to investigate the association of myeloperoxidase G-463A polymorphism with clinical outcome of Helicobacter pylori infection. METHO...
AIM This study was carried out to assess the prevalence of Helicobacter pylori infection in various ABO blood groups of people of Kashmir. METHOD The study comprised 80 individuals - 50 peptic ulcer patients (whose disease was diagnosed by endoscopy) and 30 asymptomatic volunteers. Every subject's blood group and Rhesus status was determined by standard serological tests. Helicobacter pylori ...
Several infectious agents are considered to be causes of cancer in human, mainly hepatitis B and C viruses, high-risk human pailloma viruses, Helicobacter pylori, Clonorchis sinensis, and Opisthorchis viverrini. Here we described the evident research and the association between Helicobacter spp. and biliary tract cancer particularly cholangiocarcinoma (CCA). Global epidemiological studies have ...
