It was studied the time of permanence of Vibrio cholerae 01 in the transport media Amies, Amies with charcon and Stuart. Thus, the faecal samples of thirteen cholera patients were collected and transported in those media included Cary - Blair medium. Through the fortnight cultures of each sample, V. cholerae 01 was isolated as follow: during the firsts 30 days in Stuart medium (p=l.OO). During 45 days Cary-Blair medium (p=0.095) and during 60 days in Amies wilh charcoal medium (p=Ü.199). Results indicate that V. cholerae 01 could be transported in all the media evalualed, except in Amies medium. In those media V. chalerae 01 has recovered under its culturable and viable form during the study time.

Industrial effluents without treatment or supervision by the authorities pollute the environment. Solving the problem does not go only by the control, supervision and penalties for companies that generate effluents, require its own investigation as well as develop specific treatments, accessible and affordable that can be adopted by each industry. The primary treatment is removal by physical or chemical means a substantial part of sedimentable or floating material, reducing an important fraction of the organic load, which represents a significant percentage of solid contaminants. Within the types of primary treatment quote coagulation and flocculation. The main objective was to evaluate the efficacy of two coagulants in reducing the pollution potential of effluents from the fruit processing plant. To make the primary treatment: were assayed two chemical substances, aluminum sulfate as in...

We are analyzed forty samples of raw milk commercialized at the Callao Market between January and March 2009 using presumptive method for β-lactamics and tetracycline antibiotic residues from IDEX laboratories, to comply with the limits of sensitivity of residues of the FDA. We found 40% of samples tested positive for β-lactamic residues in raw milk. There were no positive outcame to analyze tetracyclines. The results suggest that we should establish policies for legislation, regulation and training and that the NTP 202.001.2003 should be reviewed. The results suggested that should be established policies for legislation, regulation and training, and the NTP 202. 00102003 should be reviewed.

The objectives of the present investigation were to deted cases of pulmonary tuberculosis and to determine the prevalence rate between subjects: 776 students with ages between 5 and 18 years old, of both genders. We divided them in two groups: A) to 193 boys up to 7 years old,who were applied the PPD test. If the papule were greater or equal to of 10 mm. in diameter, the students were submitted to a radiological examination and sputum test. Positive casespassed a clinical examination. B) Students that were older than 7 years (n=573), were applied an epidemiological survey. The positive ánswers to cough for more than 15 days, fever, sweat, loss weight or being in clase contact with sick people of TBC, were categorized as a respiratory symptomatic ethiology ; the confirmation was made using baciloscopy technique. The diagnosed cases as positive were incorporated to the Health Department N...
