Abstract

Vaccination and antiviral drug are often used to control influenza. However, the effectiveness of vaccine was impaired due to the emergence of new variant of virus strain. Antiviral drug consists of prophylactic and curative substances, namely M2 ion channel inhibitors (adamantane; amantadine and rimantadine) and neuraminidase (NA) inhibitors (NAIs; oseltamivir, zanamivir, peramivir, laninamivir). The synthesis and modification of antiviral neuraminidase (NA) inhibitors (NAIs) and adamantanes increased the antiviral effectiveness. The mechanism of the neuraminidase inhibitor is to prevent influenza infection by inhibiting the release of the virus from internal cells. Adamantane is antiviral drug that selectively inhibits the flow of H+ ions through M2 protein to prevent the uncoating virus particles getting into the endosome. The substitution of (H275Y, S247N, I223L, K150N, R292K, I222T, R152K, R118K, E119V) on NA protein caused resistance of avian influenza virus against the neuraminidase inhibitor. The combination of mutations (S247N, I223L, K150N) increased the resistance of influenza A (H5N1) virus. The diffusion of adamantane resistance varies among HA subtypes, the species of host, the period of isolation, and region. Mutations at residues of 26, 27, 30, 31 or 34 transmembrane M2 protein caused adamantane resistance. The unique substitution (V27I) of M2 protein of clade 2.3.2 H5N1 subtype isolated in Indonesia in 2016 has been contributed to the amantadine resistance. Antiviral combination of M2 ion channel inhibitors and neuraminidase (NA) inhibitors is effective treatments for the resistance.

Abstract

Genetic improvement for economic traits such as growth is important in beef cattle selection program. This paper discusses melanocortin-4 receptor (MC4R) gene as a candidate gene for rapid growth based on its function, location and pathway, as well as its polymorphism and identified genotypes associated with economic traits, and its application as a marker-assisted selection. MC4R is a prominent gene encoding growth traits and has a critical role in mediating the effect of leptin in regulating food consumption and energy balance. Many identified MC4R gene polymorphisms are associated with growth traits. The MC4R gene, therefore, is considered as a functional candidate gene for growth traits and can be used as a marker in selection program based on molecular genetics. The use of molecular markers such as MC4R gene, therefore, can be applied in genetic improvement program for growth traits in cattle. By using MC4R gene, the efforts to build breeding system in small populations can be proposed. For instance, with an effective population size (Ne) of about 40 heads, the first generation (G1) will be obtained with a composition of GG 61.1%, CG 33.3% and CC 5.6% and male and female ratio of 178:11 and generates ideal Ne of 41 heads. In the third generation, therefore, GG composition will be 100%. The results of molecular analysis can be further used as a guideline in the development and genetic improvement strategies of beef cattle.

Abstract

The livestock sector can improve the community's economy and has a role in fulfilling food needs, especially animal protein. One of the problems in the livestock sector is the presence of infectious diseases that consequently need treatment using veterinary drugs. This paper describes the use of enrofloxacin antibiotics as veterinary drug and their residual hazards on public health. Enrofloxacin is an antibiotic from the family of fluoroquinolones (second generation of quinolone). Enrofloxacin is a broad-spectrum antibiotic that is effective to kill Gram positive and negative bacteria, so it was used for the treatment of various diseases in animals. Pharmacokinetically, enrofloxacin will be metabolized into ciprofloxacin and other metabolites. The improper use of enrofloxacin antibiotics caused residues in food products of animal origin, microbial resistance and toxicity, therefore the use of enrofloxacin needs to be monitored and evaluated for the sake of animal health and society.

Abstract

Fumonisin contamination in food is limited around 2 – 4 ppm and in feed for different animals varies from 5 to 100 ppm. This regulation is to prevent animal and human from carcinogenic effect from fumonisins. Measurement of fumonisins frequently uses chromatography methods such as High-Performance Liquid Chromatography (HPLC) and Liquid chromatography tandem-mass spectrometry (LCMS/MS); however, the sample preparation and analysis process for these methods are costly and time consuming. Immunoassays have also been employed for detecting fumonisins in food or feed. Unfortunately, the instability of antibody to harsh condition such as high temperature and pH becomes the drawback for immunoassay method. Currently, the technology based on molecularly imprinting, which is called synthetic antibody, has been established for replacing antibody functions. Therefore, the aim of this review is to describe development of molecularly imprinted polymer (MIP) in fumonisin analysis in feed and food. Herein, the composition and production of MIP were described comprehensively. Bulk polymerization and solid phase synthesis were methods for production of MIP in micro and nano sizes. The application of MIP was reported for sample preparation as solid phase extraction measured continuously by HPLC showing the high recovery (> 60%). Then, MIP replaced antibody in direct competitive enzyme-linked immunosorbent assay (ELISA) for quantifying fumonisins in maize with high recovery (>90%) and limit detection (2 – 6 pM). Lastly, MIP was also employed in electrochemical sensor application as receptor for recognizing fumonisin in milk and maize. In conclusion, the performance of MIP has been applied successfully for fumonisin analysis comprehensively from sample preparation and quantification. The MIP would be developed for wider application for other toxins in feed or food such as veterinary drug, heavy metals, or pesticides.

Abstract

The objective of this paper is to explore some efforts to increase milk protein of dairy cows through a milk protein control gene selection approach. Improving the quality of cow's milk has shifted to increase milk protein levels, due to nutritional and economic interest. The breeding process in producing dairy cattle with the advantage of having high milk protein content is more effectively carried out by molecular biotechnology approaches. The content of cow's milk protein is controlled by cow's milk protein control genes. In the process to produce dairy cattle with the advantage of having high milk protein content, it can be done with a selection approach based on milk protein control genes, namely CSN1S1, CSN2, CSN1S2, and CSN3. Once known, the main controller gene that causes high levels of cow's milk protein, it will be easy to identify dairy cattle that have these advantages, so that the selection of dairy cattle can be done since at early age.
