    A comparative study of the microorganisms found in the vaginal flora of pill and non pill user by Pap smear
    Bayate, Aimee Sarena L. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1994-03)
    This study was conducted to identify and classify the organisms that are present in pill users and non-pill users. It will determine if taking of pills cause changes in the microflora of pill (combined) users and will describe the profile of both pill and non-pill users. The study use 200 prepared smears of the vagina, divided equally to both pill and non-pill users. The slides were collected at Dr. Ricardo Y. Ladrido Memorial Hospital, Lambunao, Iloilo by the family planning physician with the help of the medical technologist. The profile of the patients were also gathered to provide more information about the subjects. The organisms were identified according to their basic morphological characteristic. The results indicate that bacilli which is the normal inhabitant of the vagina is present in 200 samples. Cocci is present in both groups but occure more in women who are pill users. In the parasite group, Trichomonas vaginalis is present in women who are pill user and Candida is present in both groups but occur more in women who are pill users. The test for the estimation of the difference between two proportions reveal that the z values obtained from the experiment falls between the critical region which has a value of 2.58. Such a value indicate that the prevalence of parasites and bacteria are equal among pill and non-pill users.

    Biosorption of Copper (CU) and Lead (PB) by heavy metal-resistant bacterial isolates from Iloilo River
    Ampuan, Naira Mitz W. (Division of Biological Sciences, College of Arts and Sciences,University of the Philippines Visayas, 2012-04)
    Many indigenous organisms isolated from sites contaminated with heavy metals have tolerance to heavy metal toxicity and these microbial activities have always been the natural starting point for all biotechnological applications. It is therefore necessary to isolate bacterial strains with novel metabolic capabilities. In this study, a total number of 18 heavy metal-resistant bacteria (10 Pb-resistant and 8 Cu-resistant) were isolated from Iloilo River sediment samples (10° 41.974’N, 122°34.187’ E). Biosorption of Cu and Pb by the bacterial isolates was characterized to evaluate their applicability for heavy metal removal from industrial waters. Selecting the highest resistance to metal toxicity’ and biosorption, 4 isolates were identified by phenotypic characterization. Identification of the top four metal-resistant isolates designates: Vibrio charchariae (83%) for Cu4; Vibrio harveyi (79%) for Cu6; Moraxella equi (100%) for Pb8; and Phoecoenobacter uteri (92%) for Pb9. Evaluation of specific metal biosorption by the isolates after incubation for 48 h suggested that none of the isolates have good potential for bioremoval of metals from contaminated environments.
