Ponce de León Rosales 3 1 National Institute of Medical Sciences, Mexico City, mexico, Mexico, 2 National Institute of Medical Sciences, Mexico City, Mexico, 3 Birmex, Mexico City, Mexico Background: Tuberculosis is major public health problem, left untreated, each person with active TB disease will infect on average between 10 and 15 people every year. Preventive strategies are essential for the achievement of the Millennium Development Goal. Methods: In 1992 a HCW’s surveillance program was instituted in our hospital, which consist in an initial evaluation for every worker during their first week of working within the Institute, a questionnaire with demographic and risk variables, PPD application, and a basic risk prevention’s course. PPD Booster is applied for those with an initial PPD negative test, and then annual follow-up is performed. The workers with PPD positive test are evaluated by a physician and a chest-Rx is taken. Prophylaxis is indicated in every HCW who has a PPD positive test during the follow up or risk factors for the disease. Results: A total of 5513 HCW have been evaluated since 1992, 61% were women, and the median age was 27. Forty percent were physicians, 32% nurses, 10% administrative workers and the rest (18%) from other areas. Of the evaluated workers 1932 (38%) had an initial PPD positive test, all of them had a normal chest-Rx. After the Booster application we identified 286 workers with positive test. During the follow up 259 HCW have had a PPD positive test. A total of 169 prophylactic treatments have been provided, 53 workers did not finish the treatment because of mild secondary effects and personal decision. Sixteen HCWs have developed clinical tuberculosis, 9 had a previous PPD positive test and refused prophylactic treatment. Conclusion: The initial PPD positive test prevalence was 43%. HCWs are in risk of this infection especially in developing countries. A a specific program for them is essential in order to reduce nosocomial transmission and identify those in risk of tuberculosis.

Sharma, V. Pandey, J. S. Joodan Faculty of Veterinary Science & Animal Husbandry, Sher-e-Kashmir University of Agricultural Science & Technology of Jammu, Jammu, J & K, India Background: Mastitis has been known to cause a great deal of loss or reduction of productivity, to influence the quality and quantity of milk yield, and to cause culling of animals at an unacceptable age. Apart of its economic importance it also carries public health significance. Although sub clinical mastitis (SCM) is more prevalent than clinical mastitis in developing countries including India, as sub clinical disease is not manifested as visible changes in the mammary glands or in the milk, it is therefore not easily recognized by farmers. . Methods: A study was conducted to determine the prevalence of mastitis and associated risk factors. The screening for mastitis was done by Sodium lauryl sulphate test (SLST) as per the method of Pandit and Mehta (1969) and Somatic cell count (SCC) (Schalm et al. 1971). Clinical mastitis was confirmed on the basis of physical examination of udder and visual examination of milk for presence of flakes, clots, pus, odor and discoloration apart the tests used for SCM. Quarter was defined as mastitis positive if it have a SLST score of >1+ or SCC 5 X 105 per ml of milk and a animal was define as mastitis positive when it has atleast one of quarters with a SLST score 1+ or >5 X 105 per ml of milk. For SCC, a quarter will be considered to have mastitis when the SCC >5 X 105 per ml of milk. Results: In the present study, a total of 46 (18.04%) cows and 65 (6.97%) quarters had clinical mastitis. A total number of cows affected with sub clinical mastitis were 196 (76.86%) out of 255 by SLST and 172 (67.45%) out of 255 cows by SCC and 8.63% teats were blind. Among risk factors, the higher prevalence was in 2nd and 8th parities and late stage of lactation. Age wise 3 to 6 years old cows had high prevalence (55.10%) followed by >6 years age and
