DAVAO CITY—An experiment on milkfish bile to treat bacterial
diseases got the nod of judges in the Sixth National Science
Quest held in Calapan City in Mindoro last month, and earning
a slot for the winner to the International Science Quest in
The discovery of the bile of milkfish (bangus) as effective
medicine against diseases was the entry of Myra Dawn Villocino,
a third-year student of the Nabunturan National Comprehensive
High School (NNCHS) in Compostela Valley, to the science quest.
The bile extract was found to be an effective antibacterial
medicine against four kinds of bacteria— Staphylococci
aureus, Escherichia coli, Bacillus cereus and Pseudomonas aeroginosa—Rowena
Pontillo, Villocino’s coach, said.
Dr. Edward Coloma, Compostela Valley (Comval) Provincial Hospital
director, said the four are aerobic bacteria and could be life-threatening
if without proper and immediate medication, the provincial information
office said in a statement.
Other than discovering the antibacterial effect of milkfish
bile, Villocino also presented a side paper on using milkfish
bone as additive to commercial flour, at a ratio of 75-percent
fishbone and 25-percent flour.
Villocino competed with 46 entries from public schools nationwide
in the annual science quest.
Pontillo was no stranger to the national science quest, the
Comval information office said. Pontillo, now a ComVal provincial
government employee, herself copped fourth place in the 2007
Science Investigatory Project Teacher Category.
She had coached Harold Kenneth F. Rallos, who bagged the Petron
Corporate Award during the Intel Philippine Science Fair in
2008 held in Tagaytay City.
As champion, Villocino would represent the country in the coming
competition to be held in Thailand.
Villocino is the daughter of Provincial Social Welfare and
Development Office Raul Villocino.
