Brucellosis is the most important zoonotic disease constituting a public health problem in Assiut Governorate, hence this study was carried out to determine the prevalence of brucellosis among humans in Assiut Governorate. A total of 7154 peripheral blood samples were collected from patients with fever at Assiut Fever Hospital during the period from 2002-2003. A full detailed anamnestic and clinical assessment in the form of questionnaire was designed for each individual to determine the risk factors with specific emphasis to age, sex, residence and occupation. All serum samples were screened for Brucella antibodies by slide agglutination test. Positive sera were further analyzed by standared tube agglutination test. Enzyme linked immunosorbent assay (ELISA) was carried out to detect IgM and IgG Brucella antibodies. Statistical analysis was performed and correlation coefficient was done between all risk factors. Results declared that the prevalence of brucellosis was (1.29 +/- 0.004 %) and (1.22 +/- 0.002 %) as detected by agglutination and ELISA, respectively. IgM antibodies were estimated in 9.8 % of the examined patients, while IgG antibodies were found in 30.4 % of the examined patients, moreover both IgM and IgG antibodies were detected in 54.3 % of the examined patients. The prevalence of brucellosis was significantly (P 0.05) affected by sex, where the rate of detection was higher among females (1.76 +/- 0.009 %) than males (1.05 +/- 0.004 %) as detected by agglutination test. On the other hand, the prevalence rate based on ELISA was (1.64 +/- 0.39 % and 1.01 +/- 0.89 %) for females and males, respectively. Prevalence of brucellosis was higher in rural areas (1.3 +/- 0.005 % & 1.25 +/- 0.009 %) than in urban areas (1.23 +/- 0.001% & 1.12 +/- 0.01 %) as detected by agglutination test and ELISA, respectively. The prevalence of brucellosis varied significanctly between different occupational and age groups. Public health impact of brucellosis is discussed and suggestive measures for control are explained.

Background/Aim: Helicobacter pylori is considered as one of the most common chronic bacterial zoonotic infections worldwide. H. pylori infection constitutes a public health hazard problem with a fatal sequele. This study was designed to estimate the prevalence of H. pylori among children and adults in Assiut Governorate in Upper Egypt and to evaluate the risk factors affecting the increase of infection. Methods: A total of 200 peripheral blood samples constituting 50 samples from children and 150 samples from adults were collected from hospital patients. A full detailed anamnestic and clinical assessment in the form of questionnaire was designed for each patient to determine the risk factors with specific emphasis to age, sex and residence. Seroprevalence of H. pylori IgG antibodies was evaluated by using enzyme linked immunosorbent assay. Results: We estimated a seroprevalence rate of 75.5%. H. pylori exposure was higher in adults (79.33%) than in children (64%) and it was statistically significant. The seroprevalence of infection was higher in rural areas (87.3%) than in urban areas (40%). Conclusion: H.pylori infection was prevalent among humans in the areas studied. Public health hazard of H. pylori infection and preventive measures to control the infection were discussed
