    Risk zone mapping of 2010 dengue fever and dengue hemorrhagic fever cases in the Province of Iloilo based on land cover
    Andrada, Thresdale; Cañonero, Gertrude Mikee; España, Regine Marie; Puno, Abigail; Sarangaya, Dorothy Rose; Tan, Leonard; Tejada, Ma. Corazon (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2013-04)
    Dengue is considered as one of the most important vector-borne diseases in many tropical and subtropical countries. Iloilo Province had 8201 cases in 2010. Heterogeneity in the risk of disease transmission results from spatial heterogeneity in both land use and land cover. Thus, the present study was conducted to identify the risk zones of Dengue Fever and Dengue Hemorrhagic Fever in Province of Iloilo in 2010 based on land cover types by using GIS software. Results of the study show that all land covers in the 6th district pose moderately low risk on dengue incidence. In the case of the 1st district of Iloilo, on the other hand, water bodies have the highest probability of dengue incidence, while the rest of the districts (2nd, 3rd, 4th, 5th). built-up areas have the highest probability of dengue incidence. The land cover type in Iloilo, therefore, with the highest risk for dengue incidence are built up areas due to its high population density, multitude of households and stagnant water areas.

    Water politics: The influence of power politics in accessing domestic water at Hamtic and Sibalom, Antique
    Aller, Emmanuel C.; Macuja, Yra Frances O. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2017-06)
    Philippines has a total annual renewable water of 479 billion cubic meters from surface and groundwater sources (ADB. 2013). Despite this seeming abundance, water supply remains scarce and unequally distributed among rural communities. To address this gap, the national government has come up with various funding mechanisms for small domestic water infrastructure projects. This paper describes the different features of the barangay governmentrun water projects in Hamtic and Sibalom, Antique, funded through Congressional Priority Development Assistance Fund (PDAF) from 2003-2013. It examines how formal mechanisms (government funding process) and informal arrangements (clientelism and power politics), influenced the access of barangays to water projects. It also describes how distance from the project site, financial capability, quality of water service, and relationship between households and incumbent politicians influenced people’s water access from the barangay government-run water utility once completed. Interviews among district officer, managers, barangay captains; and survey on 80 and 79 households in the two locales were utilized. Clientelism and power politics was found to have a general effect on how funds for water was allocated and accessed by the barangay from amongst many in the Congressional district. However, such was not prevalent in individual to barangay level of access.

    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. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2010-03)
    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.
