Distribution of extended-spectrum β-lactamase producing genes in an integrated poultry-fish farming system in Bogor, Indonesia.

Background And Aim: The excessive use of antimicrobials in livestock farming leads to the emergence and dissemination of antimicrobial-resistant organisms. This study aimed to detect extended-spectrum β-lactamase (ESBL)-producing genes in integrated poultry-fish farms in Bogor, Indonesia.

Materials And Methods: A total of 256 samples were collected from six poultry-fish farms.

A preliminary metagenomics study of bacteria present in the dirt of Swiftlet farmhouses based on nitrite levels in edible bird's nest on Sumatera Island, Indonesia.

Background And Aim: Since the past decade, metagenomics has been used to evaluate sequenced deoxyribonucleic acid of all microorganisms in several types of research. Nitrite contamination originates from the natural environment in Swiftlet farmhouses (SFHs) and can influence nitrite levels in edible bird's nest (EBN). It is strongly speculated that the conversion process into nitrite is influenced by the bacteria present in SFHs.

Risk assessment on rabies entry through hunting dog movement with semi-quantitative approach to Sumatera Island, Indonesia.

Objective: The objective of this study was to assess the risk of rabies entry through the movement of hunting dog from Garut District to Sumatera Island with a semi-quantitative approach.

Materials And Methods: Rabies entry assessment used the standard risk analysis according to the World Organization for Animal Health, with a semi-quantitative approach referring to Australian Biosecurity. Risk estimation calculation used Microsoft Excel and probabilities were estimated using Monte Carlo stochastic simulation modeling with @Risk (Palisade Corporation).

Detection of multi-drug resistant (MDR) and gene prevalence at a pig farm in Kupang , Indonesia.

Objective: The purpose of this study was to detect the incidence of multi-drug resistant (MDR) and the spread of genes that encode tetracycline (TE) resistance in in pig farms in the city of Kupang, Indonesia.

Materials And Methods: Samples of pig feces have been obtained from 96 pig farms in Kupang city, Indonesia. bacteria were isolated and identified morphologically and biochemically, and finally confirmed by the API test.

Diversity of lactic acid bacteria in dadih produced by either back-slopping or spontaneous fermentation from two different regions of West Sumatra, Indonesia.

Aim: Dadih samples from two different origins (Kamang and Gadut in West Sumatra) manufactured with different methods (back-slopping or spontaneous fermentation) were evaluated for the diversity of lactic acid bacteria (LAB).

Materials And Methods: Four dadih samples manufactured with two different fermentation methods were obtained from Kamang and Gadut regions. Both genotypic and phenotypic characteristic (16S rRNA partial gene sequence analysis and carbohydrate fermentation profile) were used to analyze the diversity of dadih LAB population.
