Abstract

This research was aimed to examine the heating effect at 70 C for 3.5 seconds on Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) decontamination in edible birds nest. This study used 40 clean edible birds nest samples. Samples were divided into two groups, first group was contaminated with E. coli and second group was contaminated with S. aureus. Each group was divided into two treatments. The first treatment was directly tested for microbiological examination and the second treatment was heating at temperature 70 C for 3.5 seconds prior to microbiological examination. The results showed that both of bacteria E. coli and S. aureus had been destroyed by heating treatment. Heating process at 70 C for 3.5 seconds was effective for decontamination of both E.coli and S.aureus.

Abstract

This study aimed to determine the presence of Salmonella spp. in duck meat and to identify the resistance of Salmonella spp. against several antibiotics in duck meat associated with food safety. Total of 52 meat samples of ducks was collected from 5 subdistricts in Bogor District, i.e., Cariu-Jonggol, Gunung Sindur, Klapanunggal, Parung Panjang, and Ciomas based on the assumption of 95% confidence level, 50% predicted prevalence, and 10% standard error. The results showed that three samples (5.8%) were positive Salmonella spp. The majority of Salmonella spp. isolated from duck meat showed resistance against erythromycin (66.7%), streptomycin (33.3%), and chloramphenicol (33.3%). Nevertheless, Salmonella spp. was still sensitive againts enrofloxacin, trimethoprim sulfamethoxazole, cephalothin, ampicillin, nalidixid acid, tetracycline, and gentamicin.
PENERAPAN METODE PENCUCIAN DENGAN AIR MENGALIR UNTUK MENURUNKAN KADAR NITRIT PADA SARANG BURUNG WALET (Application of Washing Method under Running Water to Reduce Nitrit Level of Edible Birds Nest) Susilo, Heru; Latif, Hadri; Ridwan, Yusuf

Abstract

This study was aimed to determine the influence of the washing method under running water on nitrite levels of edible birds nest (EBN). Total of 40 samples of EBN were divided into four groups with different washing frequency, control group without washing treatmet (P0), once, twice, and three times washing treatment (P1, P2, and P3) respectively. Each washing was performed for 30 seconds under running water. Nitrite levels assessment was carried out by spectrophotometry at 540 nm of wavelength. The results showed that the average nitrite levels of EBN in P0, P1, P2, and P3 were 93.124.40 ppm, 65.243.38 ppm, 63.603.81 ppm, and 30.872.11 ppm, respectively. The nitrit level in edible birds nest decreased significantly (P0.05) by using three times washing.

Abstract

Background Livestock raised in densely populated areas can serve as reservoirs for bacteria such as Escherichia coli, which may harbor antibiotic resistance genes that threaten both animal and human health. Objective This study aimed to identify and characterize quinolone resistance genes in E. coli isolated from dairy cattle feces. Methods Fifteen E. coli isolates were obtained from 15 dairy farms located in Kebon Pedes, Bogor, West Java. Genotypic detection of quinolone resistance genes was conducted using DNA sequencing on the MinION platform. Results All E. coli isolates (100%) carried at least one quinolone resistance gene. Of these, ten isolates (67%) contained a single resistance gene, while five isolates (33%) possessed two genes. The qnrS1_1 gene was identified in all isolates and represented the predominant genotype, whereas the qnrVC4_1 gene was found in five isolates (33%), mostly co-occurring with qnrS1_1. Both genes are plasmid-mediated and categorized as plasmid-mediated quinolone resistance (PMQR) genes. Conclusion The detection of qnrS1_1 and qnrVC4_1 genes in E. coli isolated from dairy cattle feces indicates that livestock manure may act as a reservoir for quinolone resistance genes, contributing to their persistence and potential spread within farm environments.

Abstract

Escherichia coli (E. coli) merupakan bakteri indikator resistansi antibiotik yang banyak teridentifikasi pada kotoran sapi perah dan dapat menjadi reservoir utama dalam penyebaran gen resistansi antibiotik dari peternakan ke lingkungan sekitar. Penelitian ini bertujuan mendeteksi dan menganalisis keberadaan gen resistansi antibiotik golongan tetrasiklin (tet) pada E. coli yang diisolasi dari kotoran sapi perah di Kota Bogor. Sebanyak 15 isolat E. coli dari 15 peternakan di Peternakan Sapi Perah Kebon Pedes, Kota Bogor yang telah dikonfirmasi pada penelitian sebelumnya, kemudian dilakukan deteksi gen tet menggunakan MinION Oxford Nanopore Technologies. Hasil pengujian menunjukkan 8 dari 15 (53,3%) isolat E. coli teridentifikasi membawa gen tet dengan pola distribusi satu hingga dua gen per isolat. Gen yang paling banyak ditemukan adalah tetB (20%), diikuti oleh tetA, tetM, dan tetO dengan persentase yang sama (7%).  Sebanyak 60% gen yang teridentifikasi berasal dari plasmid dan 40% lainnya berasal dari kromosom. Dominasi gen pada plasmid mengindikasikan tingginya potensi penyebaran gen resistansi ke lingkungan sekitar, yang berisiko terhadap kesehatan masyarakat.
