Zoonotic Pathogens From Illegally Traded Wildlife Justify Adopting The One Health Perspective In Disease Response, Marianne Allison G. Lee, Vinyl Joseph S. Valeza, Jonathan Patrick H. Yan, Ronald Allan L. Cruz Jan 2022

Zoonotic Pathogens From Illegally Traded Wildlife Justify Adopting The One Health Perspective In Disease Response, Marianne Allison G. Lee, Vinyl Joseph S. Valeza, Jonathan Patrick H. Yan, Ronald Allan L. Cruz

Recent studies have described a direct relationship between the illegal wildlife trade (IWT) and the prevalence of zoonotic pathogens in human populations. In the Philippines, the Philippine Integrated Disease Surveillance and Response (PIDSR) framework outlines the monitoring, response, and management of disease outbreaks, but needs to be updated in the wake of zoonoses from IWT. Here, we identified zoonotic pathogens that may be introduced to human populations through the IWT, pinpointed potential outbreak hotspots, and provided recommendations on how to improve the Philippines’ public health response while considering One Health. Using seizure data from the Biodiversity Management Bureau (DENR-BMB) covering …


Decolorization Of Synthetic Textile Dyes By Fungal Endophytes Isolated From The Leaves Of Philippine Mangrove (Avicennia Marina), Steve P. Obanan, Resureccion B. Sadaba, Pamela Alva-Gatchalian, Annabelle V. Cadiz, Evelyn M. Basilio, Dennis B. Bela-Ong Jan 2022

Textile dyes in wastewater can be harmful pollutants when released into the environment without treatment. Biodegradation of textile dye effluents by different microbes, including fungi, has become popular as an alternative to physicochemical methods. The mangrove Avicennia marina is known to harbor endophytic fungi which have the potential to carry out dye degradation. Therefore, this study assessed the ability to decolorize synthetic dyes of endophytic fungi isolated from the leaves of A. marina. Of the nine fungal endophytes, Aspergillus niger, Syncephalastrum racemosum and Penicillium citrinum exhibited the highest mycelial growths in solid media, while all endophytes adsorbed Congo red. Through …


First Contribution To Labiobaetis Novikova & Kluge In Cambodia (Ephemeroptera, Baetidae), With Description Of Two New Species, Thomas Kaltenbach, Jhoana M. Garces, Jean-Luc Gattolliat Jan 2022

First Contribution To Labiobaetis Novikova & Kluge In Cambodia (Ephemeroptera, Baetidae), With Description Of Two New Species, Thomas Kaltenbach, Jhoana M. Garces, Jean-Luc Gattolliat

Biology Faculty Publications

Material collected in 2018 in Cambodia gives us first insights into the diversity of Labiobaetis Novikova & Kluge, 1987 in this country. No species has been reported so far. We identified two new species using a combination of morphology and genetic distance (COI, Kimura 2-parameter). They are described and illustrated based on their larvae. A key to all Labiobaetis species of continental Southeast Asia is provided. The interspecific K2P distance between the two new species is 20–21%, the intraspecific distance of one of them is 1%. The total number of Labiobaetis species worldwide is augmented to 156.


Two New Species Of Anacaena Thomson, 1859 (Coleoptera, Hydrophilidae) From Northern Luzon, Philippines, Enrico Gerard S. Sanchez, Emmanuel D. Delocado, Hendrik Freitag Jan 2022

Two New Species Of Anacaena Thomson, 1859 (Coleoptera, Hydrophilidae) From Northern Luzon, Philippines, Enrico Gerard S. Sanchez, Emmanuel D. Delocado, Hendrik Freitag

Biology Faculty Publications

Two species of Anacaena Thomson, 1859, A. angatbuhay sp. nov. and A. auxilium sp. nov., are described from Northern Luzon, Philippines. The new species can be distinguished through colour, body shape, surface puncturation and characteristic aedeagi. Descriptions are provided and complemented with habitus photographs and drawings of the aedeagi. Data on genus distribution in the Philippines are reviewed and an updated Philippine checklist is provided.


Selected Dietary Plant-Based Proteins For Growth And Health Response Of Nile Tilapia Oreochromis Niloticus, Tzodoq O. Magbanua, Janice A. Ragaza Jan 2022

Selected Dietary Plant-Based Proteins For Growth And Health Response Of Nile Tilapia Oreochromis Niloticus, Tzodoq O. Magbanua, Janice A. Ragaza

Biology Faculty Publications

Tilapia culture is one of the largest sectors of global aquaculture. Among the different species of tilapia, Nile tilapia (Oreochromis niloticus) is perhaps the top cultured species. The production of Nile tilapia has been continually increasing throughout the years resulting in genetic deterioration. Several tilapia strains with better growth performance and adaptive capability to survive in different culture conditions have been developed to alleviate the crisis. Increased demand for Nile tilapia implies higher farming cost. Plant-based proteins are utilized as partial or complete fishmeal replacements to reduce feed cost. However, these proteins can adversely affect and alter growth …


Transitions In Bacterial Communities Across Two Fermentation-Based Virgin Coconut Oil (Vco) Production Processes, Zomesh A N Maini, Crisanto M. Lopez Jan 2022

Transitions In Bacterial Communities Across Two Fermentation-Based Virgin Coconut Oil (Vco) Production Processes, Zomesh A N Maini, Crisanto M. Lopez

Biology Faculty Publications

Despite being one of the most used methods of virgin coconut oil (VCO) production, there is no metagenomic study that details the bacterial community shifts during fermentation-based VCO production. The identification and quantification of bacteria associated with coconut milk fermentation is useful for detecting the dominant microbial genera actively involved in VCO production which remains largely undescribed. Describing the constitutive microbial genera involved in this traditional fermentation practice can be used as a preliminary basis for improving industrial practices and developing better fermentation procedures. In this study, we utilized 16S rRNA metagenomic sequencing to trace the transitions in microbial community …
