Background: Colistin resistance among Gram-negative isolates is a tremendous public health problem, and there are very few studies in Nepal about these pathogens. Hence, this review provides comprehensive data on colistin resistance among Gram-negative isolates from various samples in Nepal. Methods: Articles reporting colistin resistance among various Gram-negative isolates from Nepal before July 2019 were selected; analyzed and relevant data was collected. Results: Colistin resistance was low among clinical isolates (less than 6%) in comparison to food and animal isolates (up to 69%). A wide variety of clinical isolates were colistin-resistant in comparison to food and animal isolates. Many of these isolates were highly drug-resistant and also harbored various drug-resistant determinants. Conclusion: Increased colistin resistance among Gram-negative pathogens is a serious concern. Screening of these isolates in clinical settings, animal farms, and food industries, as well as cautious use of colistin in both clinical and animal farms, is imminent.

Abstract This paper presents a new architecture of energy hubs for animal farms considering the availability of energy resources in the farm such as biogas, solar, etc. It is proposed to combine three energy carriers: biogas, heat and electricity into an aggregate system to improve the energy efficiency of the farm. The problem is to determine the optimal allocation of distributed energy resources such as biogas generators, photovoltaics, battery and electric grid, etc. with the objective function is minimizing the total cost of energy hubs, i. e. life cycle cost while subjected to the constraint of heat, electricity and gas demands. The uncertainty of renewable energy is taken into account not only with the daily and monthly variation of the resource but the forecasting error as well. In addition, the sensitivity of the life cycle cost with respect to the price of electricity is analysed in different scenarios. The problem is examined in a case study of a typical pig farm in Northern Vietnam in both cases: with and without the ability to sell the surplus electricity to the grid. The simulation result shows the effectiveness of the proposed energy hub compared to other approaches.

Salmonella enterica serovar Enteritidis and Salmonella enterica serovar Typhimurium are major foodborne pathogens of concern worldwide. Bacteriophage applications have gained more interest for biocontrol in foods. This study isolated 36 Salmonella phages from several animal farms in Thailand and tested them on 47 Salmonella strains from several sources, including farms, seafood processing plant and humans in Thailand and USA. Phages were classified into three major groups. The estimated phage genome size showed the range from 50 ± 2 to 200 ± 2 kb. An effective phage cocktail consisting of three phages was developed. Approximately 4 log CFU/mL of S. Enteritidis and S. Typhimurium could be reduced. These phages revealed a burst size of up to 97.7 on S. Enteritidis and 173.7 PFU/cell on S. Typhimurium. Our phage cocktail could decrease S. Enteritidis on chicken meat and sunflower sprouts by 0.66 log CFU/cm2 and 1.27 log CFU/g, respectively. S. Typhimurium on chicken meat and sunflower sprouts were decreased by 1.73 log CFU/cm2 and 1.17 log CFU/g, respectively. Overall, animal farms in Thailand provided high abundance and diversity of Salmonella phages with the lysis ability on Salmonella hosts from various environments and continents. A developed phage cocktail suggests a potential biocontrol against Salmonella in fresh foods.

Abstract We evaluated the antibiotic resistance of bacteria isolated from cloacal swabs of wild birds collected with mist nets in the Jequitinhonha river valley, in the state of Minas Gerais, Brazil. A total of 191 isolates from 19 individuals of 16 species was obtained and tested for resistance to five antibiotics. At Salto da Divisa 97% of the isolates exhibited a resistant phenotype, and resistance to more than one antibiotic was frequent (71%). At Jequitinhonha 36% of isolates were resistant, but 94% showed resistance to only one antibiotic. Of the five antibiotics tested, resistance to ampicillin was most frequent (in both areas), whereas kanamycin resistance was found in only one isolate. The data here obtained and other data reported in the literature show that the general premise that antibiotic-resistant bacteria arise primarily in hospitals or animal farms should be reconsidered. Bactérias Gram-Negativas Resistentes a Antibióticos em Aves da Mata Atlântica Brasileira Resumo. Avaliamos a resistência a antibióticos de bactérias isoladas por swab cloacal em aves selvagens capturadas com redes de neblina em duas regiões do Vale do Rio Jequitinhonha, Minas Gerais, Brasil. Foram obtidos 191 isolados de 19 indivíduos de 16 espécies e foi testada a resistência desses isolados a cinco antibióticos. Em Salto da Divisa, 97% dos isolados exibiram fenótipo resistente e foi freqüente (71%) a resistência a mais de um antibiótico. Em Jequitinhonha, 36% dos isolados exibiram fenótipo resistente, dos quais 94% apresentaram resistência a apenas um antibiótico. Em ambas as áreas, a maioria dos isolados apresentou resistência à ampicilina, enquanto somente um único isolado foi resistente à canamicina. Os dados aqui obtidos e outros relatados na literatura mostram que a premissa geral de que bactérias resistentes a antibióticos surgem principalmente em hospitais ou fazendas de animais deve ser reconsiderada.

SXT/R391 integrative and conjugative elements (ICEs) were detected in 8 out of 125Proteus mirabilisisolates from food-producing animals in China. Whole-genome sequencing revealed that seven ICEs were identical to ICEPmiJpn1, carrying the cephalosporinase geneblaCMY-2. Another one, designated ICEPmiChn1, carried five resistance genes. All eight ICEs could be transferred toEscherichia colivia conjugation. The results highlight the idea that animal farms are important reservoir of the SXT/R391 ICE-containingP. mirabilis.
