Intestinal parasites are considered an important public health problem. The purpose of the research was to relate environmental sanitation to the prevalence of intestinal parasites in three urban communities of the Maracaibo municipality. Type of descriptive, correlational, cross-sectional research. The identification of risk factors for environmental sanitation was made through an epidemiological sheet, involving a total of 345 individuals, including as variables to investigate the sanitation: water storage, accumulation of garbage, presence of harmful fauna and overcrowding in housing. For the identification of intestinal parasites, a direct coproparasitological examination was performed with physiological saline solution and lugol. Statistical analyzes were performed applying frequency distributions, contingency tables and association of variables using the Chi square test, applying the SPSS V.20. Regarding the main risk factors of environmental sanitation, it was found: water storage (98%), garbage accumulation (94%) and presence of harmful fauna (92%). The prevalence of parasitosis was 46%, mainly by Blastocystis sp (72%), resulting in 65% monoparasitic. 48% presented inadequate environmental sanitation, 39% of the sample presented parasitosis when there is poor environmental sanitation. In conclusion, it was found that the prevalence of parasitic infections was high, as well as the associated risk factors, which led to an association between inadequate environmental sanitation and the presence of parasitosis in the studied communities.

To determine the prevalence of Blastocystis sp. and its association with epidemiological characteristics, a cross-sectional study was conducted in two communities of the Maracaibo Municipality, State of Zulia. To collect data, an epidemiological record was used; 406 randomly selected individuals participated; for each one, a direct tological examination with SSF-Lugol was per formed. In dividuals over 18 years (72.1%) and females (51.4%) predominated. The overall prevalence of Blastocystis sp. infection was 38.9%; poly-parasitism predominated (54.4 %), identifying Endolimax nana (36.1%) as the most frequently associated commensal species, followed by Giardia intestinalis (22.1%), among the pathogens. There was significant association (p0.05). Limitations in community and personal hygiene standards are determinants for the prevalence of Blastocystis sp. in these communities.

Rabies is a lethal zoonosis, and due to its wide distribution around the world, it constitutes a relevant problem for the public health system. It is an acute viral encephalomyelitis, transmitted by the bite of an infected animal. Rabies is endemic in the State of Zulia and has been a health problem of high social impact. The objective of this study was to determine the cases of urban rabies in the State of Zulia from 2007 to July 2013 and to identify its distribution according to municipalities and species. The research is descriptive; a documentary review of records from the Regional Zoonosis Coordination of the State of Zulia was carried out for the period under study. From the 2130 diagnosed samples, a total occurrence of 117 (5.49%) cases of urban rabies was found among the different municipalities; 116 of these cases were diagnosed in animals and one in a human being, a three-year-old girl from the Maracaibo Municipality. The highest occurrence was in the municipalities of Maracaibo (42.73%) and Lagunillas (23.08%). The study recommends coordinating extension activities in communities, based on responsible pet possession and handling as well as the need to optimize vaccination procedures as a measure to eliminate the risk of infection.

In order to determine the management of biological waste generated in teaching and research laboratories in the Faculty of Medicine, a two phase, cross-sectional, descriptive study was carried out; the first study was to determine number, type and distribution of the laboratories; and the second consisted in the elaboration and application of an instrument to collect information concerning management of biological waste, according to what is established in the Venezuelan National Decree No. 2218-92. Of the total sample of 43 laboratories, 81.4% responded, 71,4% of which generate biological waste, with a higher prevalence of types B and C, followed by type D (44%). Of these the more frequent sources were blood (64%), serum (32%) and urine (28%). The harvesting and primary storage most utilized was type 1 (44%). There does not appear to be uniformity in the frequency of internal transport. In 56% of the laboratories modality of processing before final disposition is not implemented. This research revealed that laboratories in university faculties generated biological waste that can cause adverse effects on health and the environment if corrective measures are not employed in their management, and for this reason it is necessary to implement a biological waste management system.
