| Abstract Considering that Helicobacter pylori, a bacterium able to colonize the upper gastrointestinal tract and cause mucosal injury, not always can be effectively eradicated by the traditional approaches, there is an interest in alternative therapies until a vaccine be available. Honey is a food supplement with high carbohydrate content and antioxidant activity, as well as broad antimicrobial spectrum. After analyzing the physicochemical and in vitro antimicrobial properties of an Apis mellifera honey from the Atlantic forest of Alagoas / Brazil, the purpose of the present work was evaluate its in vivo effects against Helicobacter pylori in the gastric mucosa of Wistar rats. First, it was verified the success of inoculation/infection of the pathogen in... |

| Byrsonima intermedia is a species of bush popularly used to treat gastrointestinal disorders, such as gastric ulcers, gastritis, and diarrhea. Previous studies have revealed that the methanolic crude extract of B. intermedia leaves has gastroprotective and healing properties. In this new study, we specifically investigated two purified partitions, ethyl acetate (EtOAc) and water (AcoAq), obtained from the crude extract to characterize the antiulcer effects of these two partitions and the mechanisms of action of this medicinal plant. The healing effects of these partitions on the gastric and duodenal mucosa were assessed after ischemia-reperfusion (I/R) or acetic acidinduced injury. The involvement of tumor necrosis factor-alpha (TNF-alpha), interleukin... |

| Helicobacter pylori is known, worldwide, as the causative agent of gastric diseases. However, its transmission route has not been completely understood. To evaluate the survival of H. pylori (a clinical and a reference strain) artificially inoculated on lettuce and carrot samples, portions of 25 g were inoculated with approximately 10(6) CFU/g of H. pylori and packed under normal and/or modified atmosphere (3% oxygen, 10% carbon dioxide, and 87% nitrogen). The inoculated food samples were stored at 8ºC, with daily enumeration of H. pylori populations on Columbia blood agar (CBA) and/ or Helicobacter pylori Special Peptone Agar (HPSPA). When CBA with antibiotics was used, the clinical isolate H. pylori HP1 was detected for up to 72 h in sanitized lettuce... |

| The aims of our work were to determine the presence of the cag pathogenicity-island (cag PAI) and other virulence genes of Helicobacter pylori recovered from patients with gastritis and peptic ulcer, and to investigate the correlation of these virulence genes with clinical outcome. The presence of the cagA, the promoter regions of cagA, cagE, cagT, and the left end of cag-PAI (LEC), cag right junction (cagRJ), the plasticity region open reading frames (ORFs), vacA and oipA genes among 69 H. pylori isolates were determined by polymerase chain reaction. Intact cag PAI was detected in only one (1.4%) isolate. The cagA gene was identified in 52.1% and 76.2% of isolates from patients with dyspepsia (gastritis and peptic ulcer), respectively. The plasticity... |

| We report on a 29-year-old Pakistani man who presented to the clinic with epigastric pain, of one-month duration. He did not report fever, cough, vomiting blood, passing black stools, loss of appetite or diarrhea. However, he had lost 7 kg since his symptoms had begun. Clinical examination was unremarkable. Laboratory results were within normal limits. An abdominal CT scan showed a mass with enhancement in the stomach. Gastric endoscopy revealed an ulcerative mass in the fundus. An endoscopic-biopsy specimen revealed caseating granulomas with acid-fast bacilli. The patient was diagnosed to have primary gastric tuberculosis, and antituberculous medications were initiated. Cultures of the gastric mass subsequently grew Mycobacterium tuberculosis sensitive to... |
