    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.

    Risk factors and prevalence of dental caries among students at Tubungan Central Elementary School, Iloilo, Philippines
    Abalajon, Karl Vincent P.; Caoyonan, Liza Marie D.; Fernandez, Natasha Andrea; Gequinana, Apple Joy F.; Lava, Lara Cristy S.; Millado, Justine Bennette H.; Rivera, Tess Corgette A. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2011-03)
    Pulpitis has been the leading cause of morbidity among adults in Tubungan, Iloilo for the past three years. Pulpitis may develop from untreated dental caries as this make the deeper layer of the teeth more susceptible to bacterial colonization. Hence, this study aimed to determine the prevalence of and the risk factors associated with dental caries among school age children in Tubungan Central Elementary School. This study will further investigate the possible causes of the high in prevalence of dental caries, and eventually introduce means of decreasing its morbidity in the municipality. One hundred nineteen students from Grades one to six were included in the study. The dental caries status was determined using the DMFT (Decayed, Missing, and Filled Teeth) index. The dental caries status was determined using the DMFT (Decayed, Missing, and Filled Teeth) index. The nutritional status was assessed using Weight for Age (WFA), Height for Age (HFA), and Weight for Height (WFH) as parameters as parameters. The Oral Hygiene practices, socio-economic status and food intake of the respondents were determined intake of the respondents were determined through an interview schedule. The prevalence of dental caries was 75.6%, with a mean DMFT of 2.97. Grade 2 students had the highest prevalence (95%) and DMFT index (5.9) among the grade levels. The DMFT index of each grade level was found to be significantly different (p=0.000). There was no statistical significance between the DMFT indices between males and females, although the mean DMFT of females was higher than males. There is no significant association between the Socio-Economic status of the family and DMFT index of the respondents. Only food rich in cereals and starches had significant association with the DMFT index. It is recommended that the government should intensify the campaigns on Oral health alongside other forms of health education and dietary and nutrition advice.

    Bacteriological analysis of seawater from San Salvador to Belen bay areas in Banate Bay, Banate, Iloilo
    Abancio, Celyn Ann L. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines in Visayas, 2000-04)
    This study was conducted at Banate bay, Banate, Iloilo from a point from Belen to San Salvador. Two samplings were taken one week apart and was analyzed for the Most Probable Number (MPN) per ml coliform count The Multiple fermentation tube technique showed that in Poblacion approximately 100 meters from the shore had the lowest MPN values for both samplings which was >3 MPN per ml. The highest count of greater than or equal to 2400 MPN per ml was obtained in sites Belen-10, Belen-50, and Bularan-10 meters away from the shore. As the distance from the shore increases, the MPN values usually decreases, showing that the area near the shore would exhibit high coliform counts than the are further away from the shore. The tide and the weather may have affected the coliform counts because of the differences of MPN values.
