    Intestinal parasitic infections in children living in selected barangays with urban slums along Iloilo River
    Aguro, Eric D.; Banaag, Arlene D.; Jacobe, Venus N.; Ordaniel, Lilac Mared A.; Taleon, Kathleen Joy B.; Yandra, Marnelle Gay A. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2006-03)
    This cross-sectional study was performed to determine the intestinal parasitic infection in children age 0-13 years old in three selected barangays with urban slums located alongside Iloilo River. A total of 127 stool samples from 65 males and 62 females were examined by utilizing formalin-ether concentration technique (FECT) and direct wet mount thereafter using Lugol's solution. It was found out that 59.8% of the children examined were positive for one or more intestinal parasites. The most frequent soil-transmitted helminth observed was Ascaris lumbricoides (48.0%) followed by Trichuris trichiura (34.6%). Pathogenic protozoans determined were Entamoeba histolytica (9.4%) and Giardia lamblia (0.8%). Other nonpathogenic species identified were Entamoeba coli (15.7%), Blastocystis hominis (3.1%) and lodamoeba butschlii (0.8%). Parasitic infection with single species had the highest frequency of 31.5% compared to multiple infection (28.3%). The relatively high prevalence of these infections among children living three selected barangays with urban slums alongside Iloilo River was found to be independent of factors the respondents’ sex (p=0.106), age group (p=1.691), and consistency of stool sample (p=1.835). Moreover, the degree of infection in terms of sex (p=3.174), age (p=9.136), and consistency of stool samples (p=2.798) were not statistically different from each other. The high prevalence rate of pathogenic intestinal parasitic infection may have also been influenced by factors other than the ones considered, such as environmental and socio-demographic factors. The study highly suggests mass treatment and preventive measures such as health education of the community

    Identification and antibiotic resistance of enterococcus (Schleifer and Kilpper-Bälz 1984) species isolated from Iloilo river
    Ansino, Jan Reygine G. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2014-04)
    The presence of Enterococci species in the water has long been regarded as an indicator of fecal contamination. With the increasing rate of antimicrobial resistance globally, infections caused by enterococcal species became difficult to treat. The study determined the species distributions and antimicrobial resistance profiles of Enterococcus species isolated from water and sediment samples in the Iloilo River. Susceptibility of the isolates was tested against ampicillin, penicillin, ciprofloxacin, chloramphenicol, doxycycline, erythromycin, tetracycline, and vancomycin. Among the 115 fecal coliform samples, a total of 61 (53%) isolates were confirmed to belong to the genus Enterococcus. Of these, 40% were identified as Enterococcus faecalis, followed by Enterococcus faecium 33% and Enterococcus avium (4%). Isolates showed resistance to tetracycline (51%), erythromycin (18%), and doxycycline (13%) and a high level susceptibility to ampicillin (100%), chloramphenicol (93%), and penicillin (90%). Multiple antibiotic resistance patterns revealed resistance to at least four antibiotics. Six (12%) vancomycin-resistant Enterococci (VRE) were detected. The results revealed low level of antibiotic resistance in the river. However, the presence of these fecal contaminants in the river can still pose a potential risk to the human health and the of spread of antibiotic resistance genes, indicating the great importance of improving risk management practices in the river.
