RESUMO
The importance of computer science as a working tool for the health sector is an unquestionable fact in any modern society. EPIDEMO, developed by the authors, can be defined as a set of programs whose main characteristic is its ability to process a given series of data in a totally integrated way, with an epidemiological and statistical approach. EPIDEMO is a program with a good relational database, which allows preliminary statistical analyses of data that can easily be expanded with more specific statistical options, and is compatible with other programs available on the market. It is a useful, accurate and versatile tool that meets the needs of health professionals in the field of epidemiological research.

Food-borne diseases nosocomial outbreaks due to Salmonella enterica strains have a high incidence nowadays. We describe here an outbreak that occurred in July 1990 in the Malaga University Hospital, that only involves one shift of health care workers. Salmonella enterica was detected in stool samples from HCW and a first analysis revealed the presence of two different antibiotic susceptibility patterns (resistotypes) among isolated strains. Two months after the outbreak started, the CNVIS (Majadahonda, Spain) confirmed the presence of two different serotypes (bovismorbificans and enteritidis). The delayed availability of the results (due to the lack of specific sera needed in most of the clinical Laboratories) was responsible for finishing only a partial and restricted epidemiologic study in terms of source identification for one particular serotype as well as for the antimicrobial resistance studies. The molecular identification techniques, particularly the electrophoretic protein profile could overcome these problems.

Se han analizado 204 muestras de vegetales procedentes de huertas de la Vega de Granada, establecimientos pequeños, supermercados y mercado de mayoristas de la ciudad, recogidas desde febrero de 1981 a marzo de 1983, correspondientes a raices, tubérculos y bulbos. Los indicadores microbiológicos estudiados fueron bacterias aerobias, NMP de coliformes y NMP de E. coli. El porcentaje de aislamientos de Salmonella fue 4.9, corespondiente a las serovariedades S. typhimurium, S. kapemba y S, london

A single point study of atmospheric pollution has been carried out in Granada (Spain); suspended particulate matter, sulphur oxides, ammoniac, nitrogen dioxide and polycyclic aromatic hydrocarbons were determined. There were variations in relation to the month and the day of the week. The PAHs have been determined through HPLC, with a mobile phase of acetonitrile-water (75-25). The results of measurements of benzo(a)pyrene were between 1.006 and 0.485 micrograms m-3 in two different periods of sampling.
