INTRODUCTION: Salmonellosis is an important public health problem. Turtles are increasingly involved in the role of transmitters of this infection to humans. METHODS: Salmonella cases are reported to the local Surveillance Agency where interviews are carried out to address possible exposures. Molecular epidemiology techniques were used to identify species. RESULTS: In this article we report two examples of this type of infection in two places, 300 km apart in Spain. In Barcelona a turtle transmitted the disease to a small baby via her mother, and in Castellón 5 related cases of Salmonella infections were detected, and all were transmitted by imported turtles. Molecular epidemiology techniques confirmed the turtle-person transmissions and showed strong relationships between cases in Castellón and Barcelona. DISCUSSION: These examples represent the tip of the iceberg of what is happening with pet reptiles as regards transmission of this infection. We believe that it is important to assess the impact of this type of infection in each country, in order to subsequently promote prevention strategies such as: regulations for pet shops, and educating/informing families who buy reptiles as pets.

INTRODUCTION: In the last years, we have verified the increasing emergence of bacteria, specially Escherichia coli, that produce expanded spectrum beta-lactamases (ESBL), enzymes which confer resistance to all cephalosporins (except cephamycins) and aztreonam. These bacteria are frequently resistant also to non-beta-lactam antibiotics, a fact which poses an important clinical problem. METHODS: Descriptive study of ESBL-producing strains of E. coli isolated in all kind of specimens in two hospitals of Southern Alicante (Spain), throughout a period of 57 months (January 1999 to September 2003), paying a close attention to their origin (outpatients or admitted patients), co-resistance to non beta-lactam antibiotics and evolution of their incidence. RESULTS: Respectively, 3% and 2.25% of E. coli strains isolated in each hospital produce ESBL (3.83% and 2.85% of strains from admitted and 2.74% and 2.1% from outpatients). 30.73% and 24.58% of strains ESBL were isolated in admitted patients. We found in both hospitals much higher percentages of co-resistance to ciprofloxacin, gentamicin and trimetoprim-sulfamethoxazole in ESBL-producing strains. CONCLUSION: The percentage of ESBL-producing E. coli is high in our environment, but it is even more noteworthy its clear trend to increase. It is very remarkable the high percentage of ESBL-producing strains isolated from outpatients. Finally, we emphasize the high percentages of co-resistance to non-beta-lactam antibiotics.
