Sulfonamide-trimethoprim-resistant Aeromonas salmonicida and motile Aeromonas spp. from diseased fish of the GERM-Vet study carried the sul1 gene together with mostly cassette-borne trimethoprim resistance genes, including the novel gene dfrA28. The seven dfrA and dfrB genes identified were located mostly in class 1 integrons which commonly harbored other gene cassettes.

Virulence of several species of enteropathogenic bacteria has been correlated with the ability of isolates to take up the dye Congo red. To determine whether Congo red uptake might be a useful marker for virulence of motile Aeromonas species, we examined 50 strains of diverse clinical origin on a medium containing 50 micrograms of Congo red per ml. All of the strains took up the dye to various ...

During last decades there has been a continuous growth of aquaculture industries all over the world and taking into consideration the spurt in freshwater ornamental fish aquaculture and trade in Kerala, the present study was aimed to assess the prevalence of various motile Aeromonas spp. in fresh water ornamental fishes and associated carriage water. The extracellular virulence factors and the ...

“Aeromonas” (Graf, 2015) is a new coming reference hardback and ebook that provides an overview on taxonomy, ecology, and pathogenicity of the genus Aeromonas, a group of bacterial species in the gamma subclass of the Proteobacteria (i.e., Gammaproteobacteria). Aeromonas is a Gram-negative, motile, and facultative anaerobic bacterium. Some of the members are associated to infections in humans, ...

Ikan mas (Cyprinus carpio L.) merupakan ikan air tawar yang banyak dibudidayakan di Jawa Barat dan memiliki harga jual relatif tinggi sehingga secara intensif. Tingginya padat tebar konsumsi pakan pada budidaya intensif menyebabkan penurunan kualitas akibat timbunan sisa ekskresi ikan, menimbulkan stress mudah terserang penyakit. Penyakit sering menyerang adalah Motile Aeromonas Septicemia (MAS...

Lineages of hypervirulent Aeromonas hydrophila (vAh) are the cause of persistent outbreaks of motile Aeromonas septicemia in warm-water fishes worldwide. Over the last decade, this virulent lineage of A. hydrophila has resulted in annual losses of millions of tons of farmed carp and catfish in the People's Republic of China and the United States (US). Multiple lines of evidence indicate US catf...
