Abstract

Secondary metabolites of filamentous mold are mycotoxins, which in some situations can develop on foodsderived from plants or from animals. Fusarium, Aspergillus, and Penicillium are the most common types ofmold that produce mycotoxins and also often contaminate human food and animal feed. Aflatoxins includingaflatoxin B1, B2, G1 and G2 are produced by A. flavus and A. parasiticus. M1 and M2 aflatoxins arefound in dairy products. In this study, we used PCR to detect and identify mycotoxigenic fungi material infoods from traditional markets and supermarkets in Surabaya, Indonesia. Samples of chicken meat from atraditional market and from a supermarket (10 pieces each) were placed in a conical tube and crushed in PBS.The crushed samples were centrifuged and the supernatants were cultured on potato dextrose agar (PDA)media and observed using a reverse microscope. DNA was isolated from cultured samples and subjectedto PCR with primers specific for genes encoding aflatoxins. Interestingly, we revealed that the PolymeraseChain Reaction (PCR) analysis showed A. flavus and A. ochraceus were present on chicken meat sold attraditional markets and supermarkets. In sum, enhanced precautions may be needed to ensure that foods soldin traditional markets and supermarkets are free from molds that have the potential to produce mycotoxins.Further studies are needed to detect and identify the prevalence of mycotoxins in the food supply.

Abstract

Dengan adanya kejadian luar biasa yang pertama virus avian influenza H5N1 tahun 1997, semakin jelas bahwa potensi virulensi virus H5N1 telah meluas ke manusia. Review ini disusun untuk memahami karakteristik virus, siklus replikasi virus, mekanisme virus masuk ke dalam hospes, peran hemaglutinin sebagai determinan patogenisitas, urutan basa hemaglutinin yang berperan dalam memicu peningkatan virulensi dan fungsi dari 6 segmen gen lainnya pada virus avian influenza. Review juga dibuat untuk memahami gambaran gen Hemaglutinin avian influenza virus H5N1 yang bertujuan untuk mengetahui penularan secara efisien dan replikasi virus avian influenza pada manusia, sehingga penularan selanjutnya dapat diantisipasi dengan baik. Kerja sama lintas sektor antara kementerian kesehatan, kementerian koordinator kesejateraan rakyat, kementerian lain, universitas dan organisasi yang berkompeten sangat dibutuhkan untuk mendukung pencegahan penyebaran virus avian influenza H5N1 di Indonesia.

Abstract

The aims of this community dedication: 1) Improve the economy of the villagers of Watubonang and Biting, Badegan Ponorogo district through changing mindsets to improve people’s welfare 2) Increasing the knowledge and skills of the villagers of Watubonang and Biting, Badegan Ponorogo district through technology transfer for making pecticide formulations, antiscabies drugs, antiseptik, compost manure disinfectant, dipping solution based on tobacco waste. The result of the communiy dedication implementation showed an increase in participants on how to manufacture various kinds of tobacco waste products from 6.7% to 93.3% and an increase in the skills of participants on how to manufacture various kinds of tobacco waste products from 6.7% to 93.3%. in addition to the increased knwoledge and skills of the community dedication participants in Watubonang and Biting villages, Badegan Ponorogo district, it showed a decrease in the average cost of using medicines, antiseptiks, and disinfectants per house from 210 thousand rupiah to 42 thousand rupiah. Form the results of community dedication in the villages of Biting and Watubonang, Badegan Ponorogo district, it is hoped that they will become fostered villages of FKH Unair.
