“…In our investigation, the overall seroprevalence in humans was relatively high (44.4%) ( Table 3). This was somehow higher than results shown in previous studies from other countries: United Kingdom (27.6%) [28], Australia 15.4% [29], and United State (36.3%) [30], while it was lower than reports in Uganda (87%) [31], China (62%) [32], and neighboring Arabian countries, mainly Libya (94%) [33] and Sudan (65%) [34]. The diversity of crowding, socioeconomic status, and environmental and hygiene factors may play an important role in increased rates of H. pylori infection in developing countries.…”

Introduction: Helicobacter pylori (H. pylori) is one of the most common bacterial infections among humans worldwide. Although many records imply its interfamilial acquisition, the role of animals remains poorly understood. This study was undertaken to investigate the seroprevalence of H. pylori in animals and their human contacts in Cairo and Giza governorates, Egypt. Methodology: Commercial enzyme-linked immunosorbent assay (ELISA) kits were used to detect IgG antibodies to H. pylori in dogs, cattle, and humans. Results: Seropositive dogs (35/94; 37.2%), cattle (24/80; 30%) and humans (40/90; 44.4%) were found. Seroprevalence in animals significantly varied in different areas of sample collection, but there was no association with sex or age. Human seropositivity rates were associated with increasing age; moreover, seropositive dog owners (51.7%; 15/29), had seropositive dogs. However, infection was not associated with subject's sex, occupation, or history of animal contact. Conclusions: Our findings indicate H. pylori is widely distributed in cattle and dogs and their human contacts in Cairo and Giza, Egypt. Further studies to determine infection in other occupational groups are needed. This study provides baseline information on the seroprevalence of H. pylori, which may be required to begin prevention control programs in our area.

“…Asian-Pacific guidelines on gastric cancer prevention recommend screening for and eradicating H. pylori in high-risk populations (Fock et al, 2009). Since 2003, numerous studies have also been conducted to examine the prevalence of H. pylori in healthy people in different regions of China, with reported prevalence ranging from 40% to 81% (Shi et al, 2008). In our studies, we found 41.5% of migrant workers were infected with H. pylori.…”

Background: Helicobacter pylori infection leads to many upper gastrointestinal diseases. Migrant workers are the main part of floating population in China. However, up to now, their health status has not been a focus of attention. Methods: In order to assess the status of H. pylori infection among migrant workers in Shijiazhuang, over five years we interviewed 324 individuals between 2007 and 2011. Each underwent a rapid urease test to identify H. pylori infection and socio-demographic indicators were collected using a survey questionnaire. Results: Our results showed that family income (P = 0.003), dietetic hygiene (P = 0.005), education (P = 0.004) and marital status (P = 0.007) were associated with H. pylori infection. Conclusion: We found that migrant workers had little basic knowledge of H. pylori and their prevalence of infection remains high. Therefore, we need to promote education and awareness of H. pylori and to ensure access to diagnosis and treatment for infected workers.

“…No significant association was found between H. pylori infection and gender, but higher frequency of infection was observed among men in the current study. Similar observations have been reported previously in China (14). The highest frequency of H. pylori was observed in the fourth decade of life (39%) and lowest frequency (28%) was found in patients who had already completed their fifth decade of life.…”

Background: Infection with Helicobacter pylori is considered as a major cause of chronic gastritis, peptic ulcer disease and gastric cancer. More than half of the world's population is infected with H. pylori. In Sri Lanka various groups have reported a prevalence ranging from 3% to 70% over the last decade. Objectives: The aim of this study was to determine the current proportion of H. pylori and risk factors for H. pylori infections. Patients and Methods:The study was a cross sectional, descriptive study in which 100 dyspeptic patients who were required to undergo endoscopy examination were included. The study was carried out at a Teaching Hospital in Sri Lanka. In-house urease test and PCR amplification of the glmM gene of H. pylori was performed to diagnose H. pylori infection. A questionnaire was filled to collect sociodemographic data from the dyspeptic patients. Results: Eighteen dyspeptic patients were positive for H. pylori by both in-house CLO (Campylobacter-like organism test) test and polymerase chain reaction (PCR). Ten of cases were male (18%) while eight were female (17%). There was no association between the demographic factors and risk of H. pylori infection. Conclusions: The proportion of H. pylori infections was found to be 18% in the study population. There was no significant association with H. pylori and the studied demographic factors.
