Abstract

Grouper are reef fish which can be cultivated because highly commercial value. There are many different types of bacteria in the digestive tract of grouper, one of them is Staphylococcus. Staphylococcus sp. is a Gram positive, non spora, non motile, and facultative anaerobic. Most of Staphylococcus sp. are pathogenic in human and animals. The purpose of this study was to identify the species Staphylococcus sp. on grouper sold at the Kedonganan fish market, Kuta District, Badung Regency, Bali Province based on 16S rRNA sequence analysis. This study used grouper feces as a samples from 20 fishes. Staphylococcus sp. from feces were cultured in media Blood Agar. Sequence analysis 16S rRNA Staphylococcus sp. was conducted with PCR and sequencing method. This study can identify the bacteria Staphylococcus sciuri and Staphylococcus hominis.

Abstract

Avian colibacillosis is an infectious disease caused by avian pathogenic Escherichia coli (APEC). APEC ability to cause disease depends on many pathogenic factors, one of them is iroN pathogenic gene. This study purposed to find out iroN gene sequence in APEC in Bali. Two APEC isolates from free range chicken in Tabanan dan Badung has been used. The isolates have been been purified and were available at Laboratory of Veterinary Bacteriology, Faculty of Veterinary Medicine, Udayana University. Chelex 10%was used for DNA isolation. DNA amplification using published DNA primer has been conducted with polymerase chain reaction (PCR) method. The PCR product was sequenced at First Base Laboratories, Malaysia using Sanger’s Dideoxy Nucleotide Termination method. The iroN gene of both isolates can be analyzed and have 659 bp in length. Both were 100% homologous. Phylogenic test using 52 DNA sequence of iroN gene from Escherichia coli and other bacteria in the world was conducted in MEGA 5.2. All data have 24 polymorphic sites of nucleotide acid and eight polymorphic sites of amino acid. The iroN gene of Bali isolates was in the same group as iroN gene from Australia (MF174860) and Hong Kong (MF474175). This gene can be used as pathogenic marker of APEC in Indonesia.

Abstract

Beef is an essential source of protein and several functional compounds that are very important for human. The quality of beef depends on both genetic and environmental factors like feed, age, sex, and others. This research aimed to determine the composition of amino acids both Bali and Wagyu beef on the different activity of muscle, i.e. active and passive. As many as 5 g of each sample was used in this study. The active beef samples were presented by Biceps femoris, and passive beef samples were presented by Longissimus dorsi. High-Performance Liquid Chromatography (HPLC) method was used in order to an identification of amino acids according to the standard procedure. Results of the study showed that the essential amino acids content both bali cattle and wagyu were higher than non-essential, and amino acids content originated from active muscle was higher than passive muscle. Methionine, phenylalanine, and serine on bali beef cattle were lower than wagyu beef. Overall, the content of amino acids essential was lower than non-essential. In conclusion, there is no significant difference of amino acids content both bali cattle and wagyu beef, but the function of muscle (active or passive) were known contribute to the difference of amino acids content.

Abstract

This study aims to determine the level of growth hormone given feed supplement and anabolic growth promoter. This research was an experimental research using Complete Random Design (CRD) with three factors. There were feed supplement, anabolic growth promoter, and sampling time. There were 20 youngmale Bali cattle and they were taken care intensively, divided into 4 group, there were control, feed supplement, anabolic growth promoter, and the combination of feed supplement and anabolic growth promoter for five months, and measured the level of growth hormone each month. The level of growth hormone was detected by using competitive Enzyme Linked Immunosorbent Assay method. The result of the research showed that feed supplement and anabolic growth promoter increased the level of bali cattle growth hormone where feed supplement with anabolic growth promoter (P1G1) was not significantlydifferent than given feed supplement without anabolic growth promoter (P1G0). Providing feed supplement optimally by farmers is highly recommended.

Abstract

The objective of this research was to compare the levels of growth hormone in bali cattle reared in the purification of Nusa Penida with those from other regions in Bali Province. A total of 320 sera samples were collected from bali cattle reared in Nusa Penida, Klungkung, Tabanan, Buleleng and Bangli. The levels of growth hormone was determined by using sandwich Enzime Linked Immunosorbent Assay (ELISA). The results showed that a diverse levels of growth hormone in Bali cattle were observed in Bali cattle. The lowest growth hormone levels (576.4 pg/mL) was found in Bali cattle reared in Nusa Penida and the highest levels (5044.08 pg/mL) were found in the Buleleng regency. It was concluded that bovine growth hormone levels varies, depending on the regions of rared of Bali cattle. ABSTRAK Penelitian ini bertujuan untuk mendeteksi kadar hormon pertumbuhan sapi bali yang dipelihara di wilayah pemurnian Nusa Penida dan wilayah lainnya di Provinsi Bali. Sebanyak 320 sampel serum sapi bali betina dewasa dikumpulkan dari peternakan rakyat di Nusa Penida Klungkung, Tabanan, Buleleng, dan Kabupaten Bangli. Kadar hormon pertumbuhan dideteksi dengan metode Enzime Linked Immunosorbent Assay (ELISA). Hasil penelitian menunjukkan, kadar hormon pertumbuhan sapi bali terendah (576,4 pg/mL) ditemukan pada sapi bali yang dipelihara di Nusa Penida, sedangkan kadar hormon tertinggi (5044,08 pg/mL) ditemukan pada sapi bali yang dipelihara di Kabupaten Buleleng. Disimpulkan bahwa kadar hormon pertumbuhan sapi bali berbeda-beda, tergantung wilayah tempat pemeliharaan sapi bali.

Abstract

Antimicrobial resistance (AMR) is the ability of bacteria to withstand the effects of drugs so that bacteria do not die after the administration of antimicrobials and the function of the drug does not work at all. This incident is caused by the uncontrolled use of antimicrobials which can cause a global crisis on human and animal health in the future. This study aims to determine the factors that influence the behavior and perceptions of veterinarians in the province of Bali on the use of antimicrobials and antimicrobial resistance. A total of 204 veterinarians were used as research samples through a survey using a Likert system and then the results of differences in veterinary responses to the frequency of prescribing were analyzed by Kruskal-Wallis. The results showed that antimicrobials were given to half of the patients treated weekly, and the factors that influenced the administration of antimicrobials were the history of antimicrobial use, level of safety, experience, potency, side effects, and the risk of increasing antimicrobial resistance. The cost of culture testing and the price of antimicrobials are the biggest barriers for small animal veterinarians but not for livestock veterinarians. All respondents acknowledged that most sources of information on AMR were easy to obtain and useful for them. The group of veterinarians who practice small animals and livestock practitioners agree that AMR is a serious common threat in the future. This study provides important insights into the application of veterinary medical procedures in the province of Bali and will later become a reference in increasing regulation control over the use of antimicrobials.
