    Prevalence of Ascaris lumbricoides, Trichuris trichiura, and Enterobius vermicularis in the hands of preschool children in day care centers in Miagao, Iloilo
    Abellon, Rupert L., III (Division of Biological Sciences, Bachelor of Science in Public Health, University of the Philippines Visayas, 2002-03)
    The hands of 199 preschool children in Day Care Centers of Miag-ao, Iloilo were swabbed and examined for the presence of parasitic ova, specifically soil-transmitted parasites. Prevalence rates of parasitic ova were determined and tested for significant differences with variables that include age, sex, parent’s educational level, and location of the day care center of the preschoolers. Ascaris had a prevalence rate of 24.12% (48), Enterobius with 1.51% (3) and Trichuris with 1.01% (2). Toxocara canis had a 6.03% prevalence (12) in the hands of preschoolers. Using the Chi-square test to test for differences, it was shown that there were no significant differences in the presence of parasitic ova in the hands among preschoolers with regards to age, sex, and parent’s educational level except for location of the day care center. There was a significant difference in the prevalence rate of parasitic ova in the hands of preschoolers in coastal areas and those in non-coastal areas. Preschoolers in the coastal areas had a higher prevalence rate (29.82%) compared to those in the non-coastal areas (16.47%). With a sample of 121 stools from the same group of preschoolers, the study showed that there was no direct association between the presence of Ascaris ova in the hands and their presence in stools.

    Health risks associated with bacteriological quality of bathing waters in Villa Beach, Brgy. Sto. Niño Sur, Arevalo, Iloilo City
    Abad, Sue Ellen T.; Catinan, Mary Joy A.; Hautea, Therese Angelie T.; Mabang, Moctar M.; Narida, Leah Joy S.; Panggat, Kevin Matthew B.; Turija, Maisie Mae L. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2004-04)
    ABSTRACT A special problem submitted to Division of Biological Sciences, College of Arts and Sciences, University of the Philippines in the Visayas, Miagao, Iloilo. The study investigated the bacteriological quality, using E. coli, Salmonella spp., and culturable Vibrios as bacterial indicators, of four selected bathing waters in Villa Beach, Brgy. Sto. Nino Sur, Arevalo, Iloilo City, as well as the incidence of symptom occurrence associated with these microbes among 33 respondents. This was to determine health risks associated with bacteriological quality of bathing waters in Villa Beach. Conventional and modified laboratory procedures were used in the detection of E. coli, Salmonella spp., and culturable Vibrios, while pre-structured interview schedule was utilized in the epidemiological survey. p-value was used as statistical tool to measure association. All four water samples tested positive for E. coli and culturable Vibrios. Salmonella spp. was negative in all of the water samples. The MPN for E. coli in water sample C was 460 per 100 ml water sample, while in water samples A, B and D it was 240. Obtained MPN were above the DENR MPN standard for fecal coliform for Class SB, which is only 200. There were 52 individual participated in the study but only 33 (63 %) were able to complete the follow up interview done seven days after the actual date of survey. 18 (55 %) of the respondents were females. The mean (SD) age was 19.3 (14.5) years with an age range of 3-56 years. 11 (34 %) respondents came from sampling site C and 32 (97 %) were visitor-swimmers. Only 13 (39 %) of the respondents reported to have experienced symptoms during the follow up, and the most common symptoms reported by 10 (77 %) of the symptomatic respondents were upper respiratory tract symptoms such as colds, cough and sore throat. Among the symptomatic respondents, only four (31 %) were classified as cases. Significant differences were observed only in the case of symptom occurrence relative to MPN and sampling site as indicated by p-values (0.0004 and 0.003, respectively) less than 0.05. The presence of E. coli in significant concentration and culturable Vibrios in all of the four water samples indicated poor bathing water quality of Villa Beach which may pose health risks among swimmers. The incidence of symptom occurrence or health risks was positive as reported by some of the respondents in the follow up survey. Positive relationship was observed only in the case of symptom occurrence with variables sampling site and MPN for E. coli. Symptom occurrence was found out to be more likely relative to the sampling site, and that it increases with E. coli concentration present in water samples.
