Penyakit Brucellosis pada sapi disebabkan oleh Brucella abortus dan dikenal sebagai penyakitreproduksi menular pada ternak. Brucellosis merupakan penyakit zoonosis karena dapat menularpada manusia. Penelitian ini bertujuan untuk mengetahui determinan antigen yang terdapat pada genomp2a B. abortus isolat lokal yang telah diblasting ke asam amino (protein). Sampel bakteri berasaldari sapi penderita Brucellosis asal Sulawesi Selatan dan Nusa Tenggara Timur. Gen omp2a diamplifikasimelalui tehnik Polymerase Chain Reaction (PCR) dengan menggunakan primer 2ab5F dan 2a900R.Produk PCR disekuensing untuk mendapatkan sekuen nukleotida gen omp2a B. abortus isolat lokal.Sekuen nukleotida ini dianalisis tingkat homologinya terhadap isolat asal mancanegara yang diaksesdari GenBank dengan menggunakan BLAST.

Abstract

This research aimed to characterize VirB4 protein of local isolate Brucella abortus with Western blotting method. The result showed that there were four protein bands with molecular weights of 64.61, 59.25, 21.63, and 16.70 kDa by triggering a reaction between the whole Brucella abortus and anti-Brucella abortus serum. The results also revealed that there was only one protein band with a molecular weight of 59.25 kDa triggering a reaction between the whole Brucella abortus and anti-VirB Brucella abortus serum. Finally, it can be concluded that VirB4 protein can affect the virulence factor of Brucella abortus, successfully characterized with the appearance of one band with a molecular weight of 59.25 kDa by using Western blotting method.

Abstract

Scabies is a zoonotic skin disease caused by Sarcoptes scabiei mites. As an emerging/re-emerging parasitic disease, scabies represents a significant global threat to both human and animal health. Numerous cases of scabies in Indonesia have been reported, which support research on the prevalence of S. scabiei. However, most such studies have involved conventional morphological studies, with limited molecular diagnostic studies. The purpose of the present study was the genetic characterization of S. scabiei var. cuniculi in domestic rabbits to generate baseline genotypic data. S. scabiei var. cuniculi was isolated and identified from scabies-infected rabbits from the Surabaya and Malang regions of East Java. Molecular identification was performed using Polymerase Chain Reaction (PCR) using specific primers targeting the COX1 gene. We performed COX1 PCR using rabbit isolates of S. scabiei from Indonesia. To the best of our knowledge, no such study had been reported previously. This study was performed in the Laboratory of Veterinary Parasitology, Faculty of Veterinary Medicine and the Tropical Disease Diagnostic Center Laboratory, Universitas Airlangga. The results with agarose gel electrophoresis revealed a 289 bp PCR product amplified from the DNA of S. scabiei isolates from both Surabaya and Malang in accordance with the expected COX1 amplicon size, that indicated a single band 289 bp in length, demonstrating specific detection of S. scabiei var. cuniculi from Surabaya and Malang using COX1 primers. The results were consistent with the calculated amplicon size based on primer positions within the COX1 locus, with the forward primer spanning nucleotides 61–94, and the reverse primer spanning nucleotides 331–350 ( 350 − 61 = 289 bp).  PCR genotyping of the isolates yielded an identical nucleotide length of 289 bp. Further studies are required to sequence the amplified fragments for homology assessment.

Abstract

This study aimed to evaluate the Total Plate Count and total Staphylococcus aureus count of beef sold in wet markets in Mulyorejo sub-district below the National Standard Indonesia (SNI 7388:2009) about maximum limit of microbial contamination in food or not. Total of twenty four samples of beef purchased from traditional markets of Tempurejo, Krempyeng Yamuri, Pacar Keling, and Menur in Mulyorejo sub-district Surabaya were examined by Total Plate Count using pour plate method. The sample was also cultured in Mannitol Salt Agar. The colony suspected to be S. aureus were taken for identification. The identification of S. aureus consists of isolation in Mannitol Salt Agar, Gram staining, catalase test, and coagulase test. Total plate count result showed that four samples were exceeding the National Standard of Indonesia SNI 7388:2009 or 1x106 CFU/g and the rest were below the maximum Total Plate Count in SNI. The highest Total Plate Count result was 1,9x106 CFU/g and the lowest was 7,8x104 CFU/g. The result of identification showed that 100% samples examined were contaminated by S. aureus with the highest result was 2,9x104 CFU/g and the lowest result was 4,3x103 CFU/g or exceeding the SNI 7388:2009.

Abstract

The skin mucus of the rice eel (Monopterus albus) contains various antibacterial compounds and has the potential as a synthetic antibiotic. This research was conducted to explore the potential antibacterial power of the rice eel skin mucus against some pathogenic bacteria in freshwater fish. The bacteria were isolated from five samples of rice eel cultivation ponds belonging to Mr. Sabwan and then challenged with the mucus of the eel's skin through diffusion tests using paper discs. The rice eel skin mucus tested its antibacterial activity against three species of freshwater bacteria, Aeromonas hydrophila, Escherichia coli, and Staphylococcus aureus, by testing sensitivity and inhibitory zones. The inhibitory zones of each bacterium were measured using Vernier caliper which refers to the standardization of the inhibitory zone: < 4 mm no activity, 5-9 mm weak, 10- 14 mm medium, and > 15 mm strong. Test results showed that the eels' skin mucus could inhibit the growth of bacteria Aeromonas hydrophila, Escherichia coli, and Staphylococcus aureus.
