BACKGROUND: Different culture mediums were used for the isolation of Helicobacter pylori. In this study three mediums commonly used for the culture of this microorganism were evaluated: chocolate agar, Martin-Lewis medium and CP of Dent medium as well as a new selective medium Pylori agar. METHODS AND RESULTS: Over a period of 7 months gastric biopsies were collected in 112 patients with clinical manifestations of chronic atrophic gastritis. H. pylori was isolated in some of these mediums on 73 occasions (65.1%). On 72 of the 73 occasions the microorganism grew in the Pylori agar medium (98.6%) being the medium achieving the greatest number of isolations, followed by the CP of Dent medium with 67 isolations (91.7%), 65 isolations with the Martin-Lewis medium (89.0%) and 57 isolations with chocolate agar (78.0%). The chocolate agar medium was that which most frequently presented contaminant flora (35 times: 61.4%) and the CP of Dent medium achieved the most rapid and widespread growth. The colonies were largest and therefore easier to recognize in the CP of Dent and Pylori agar mediums. CONCLUSIONS: The authors recommend the association of the CP of Dent and Pylori agar mediums in the isolation of Helicobacter pylori since these two mediums provide the greatest number of isolations with the greatest growth and ease for colony recognition.

BACKGROUND: To determine the prevalence of the Borrelia burgdorferi infection in the Soria Province, and the detection of the human disease cases. METHODS: By an indirect immunofluorescence technique, we had studied total antibodies (IgG, IgM and IgA) against B. burgdorferi (B 31 strain) in the sera of 298 people (150 men y 148 women) of the Soria Province. The results were considered positive when the titers were same or upper to 1/256. All positive sera were tested for specific IgM antibodies by same method; IgM results were considered positive when the titers were upper to 1/16. RESULTS: 13.1% of the people had positive results (39 sera): 14 for women (9.5%) and 25 for men (16.7%). We detected 14 sera with positive IgM. We demonstrated titers same or upper to 1/256 in all age group, with a major prevalence in the age group between 41 and 50 years (22.6%). In all areas of the Province we detected positive results and in many of this areas the positivity was upper to 30% of the studied sera. 12 persons with positive IgM or high titers of total antibodies presented signs or symptoms of disease in relation with B. burgdorferi infection; 6 persons had alterations of the liver function do not explicable by other etiology. CONCLUSIONS: The B. burgdorferi infection present a high prevalence in this Province and a wide geographic distribution, with high endemic areas. We demonstrated patients with symptomatology compatible with Lyme borreliosis, and we wish to emphasize the frequency of alterations of the liver function in this group of people.

The inflammatory bowel disease cases in Soria have been reviewed from 1981 to 1990. Thirty-two cases of ulcerative colitis (UC) and thirteen cases of Crohn's disease (CD) have been found. The mean incidence was 3.2/100.000 inhabitants/year in UC and 1.3/100.000/inhabitants/year in CD. The prevalence was 32 and 13/100.000 inhabitants respectively. We have found a progressive increase in incidence in both UC and CD during the period analyzed. Epidemiologic data (considering the majority come from rural areas), clinical course, endoscopic and radiologic findings, are similar to the results published in the literature. We have found a minor percentage that other authors in extraintestinal signs, complications and need of surgical intervention.
