    Ascaris infections lead to malnutrition and poor cognitive development especially to children aged 5-15 years of age. In the Philippines, protein-energy malnutrition is one of the ten leading causes of child mortality. From January to February 2008, a cross- sectional descriptive study was carried out in Monteclaro Elementary School to describe the prevalence of ascariasis and the prevalence of protein energy malnutrition and relate it to the demographic factors such as age group, educational attainment of the mother, annual family income, availability of toilet, and proper hand washing practice. Sixty eight pupils of the said school were included in the study with ages ranging from 6-13 years. Fecal sample of the participants were collected, processed using the Kato-Katz smear technique, and microscopically examined to determine the prevalence of infections. The weight was measured for weight for age index. A self administered questionnaire was given to know about socio-economic factors. Handwashing activities were utilized as a basis for personal hygiene. The result of the study shows that 12% of the study population has a mild A. lumbricoides infection. Weight for age measurement shows that 21% of the pupils are underweight. Pupils of the age group 12-14 were of the highest frequency of ascaris infection and pupils of the age group of 6-8 were of the lowest frequency. Twelve percent of pupils who have toilets in their household are positive for ascaris infection. All pupils failed in the handwashing activity. Twenty seven percent of the pupils whose mothers have no formal education were underweight. This is due to the level of education that the mother has achieved. Mothers who have undergone tertiary education know more about the proper ways to nourish their children thereby minimizing children who are underweight. Twenty-three percent of the pupils included in the study were below normal in the weight for age index. Trend shows that those families with lower income have a higher frequency of respondents that are underweight. For pupils with below normal weight for age 50% are without toilet while 19% with toilet. There is low prevalence of ascariasis in Monteclaro Elementary School. The results of this study do not truly show the relationship of ascariasis with protein energy malnutrition. Inconsistencies of the results with the findings of other studies are possibly due to low number of positive ascaris-infected participants and the low number of overall participants. Increase in the sample size and ascariasis positive participants within the sample are recommended to get more accurate results.

    Antibiotic resistance patterns of selected pathogenic bacteria isolated from water and bottom sediments in the Iloilo tidal inlet (Iloilo River)
    Agustin, Eda Mae S.; Cabrias, Ligaya April May S.; Fuentebella, Elaine Joyce V.; Gestuveo, Rommel J.; Lagon, Raymond Anthonn Kriztee J.; Saldajeno, Cypruz Anne L.; Tunguia, Saer Martin J.; Villanueva, Regene Patricia Natividad V.

    In recent years, antibiotic resistance of pathogenic bacteria has become a public health concern. Although little is known of its environmental implications the presence of both potentially pathogenic bacteria and fecal coliform in rivers and other bodies of water raises the question of whether resistance transfer may actually occur in bodies of water. In relation, the Iloilo River for one has experienced changes in both ecological and sanitary conditions. With this threatening problem of both ecological and fecal pollution, the river could harbor microflora that could be of public health concern. Using the Kirby-Bauer Method, this study generally aims to determine the antibiotic resistance of pathogenic bacteria isolates (E. coli, S. typhi and V. cholerae) from water and bottom sediment samples from selected sampling areas in Iloilo River, Iloilo City. Stock cultures of bacterial isolates were obtained from the UPV-National Institute of Molecular Biology and Biotechnology (UPV-NIMBB) and were subjected to antibiotic resistance analysis using 12 different antibiotic classes. Results showed varying degrees of resistance in all of the sampling sites and species. Most isolates were highly resistant to penicillin and oxacillin and least resistant to ciprofloxacin. Multidrug-resistant isolates were also observed in all of the sampling sites and species. More isolates from bottom sediments were observed to be highly resistant than the isolates from water samples. Pearson correlation revealed that the antibiotic resistance patterns among the different species isolated from the different sources and sampling sites appeared to vary in a systematic manner indicative of a similar mechanism of antibiotic resistance development.
