Histopathology of cultured marine fish, Seriola purpurascens (Carangidae) infected with Paradeontacylix spp. (Trematoda: Sanguinicolidae) in its vascular system.

Detection of R + bacteria in cultured marine fish, yellowtails (Seriola quinqueradiata).

Many drug-resistant gram-negative bacilli were isolated from the intestinal tracts of yellowtails (Seriola quinqueradiata) cultured on farms in various parts of Kochi and Ehime Prefectures, Shikoku Island. They were Vibrio, Pseudomonas, Proteus, Citrobacter and some unidentified Enterobacteriaceae. Of these drug-resistant strains, Vibrio and Pseudomonas were found to carry R factors in high fre...

Isolation of multidrug-resistant Stenotrophomonas maltophilia from cultured yellowtail (Seriola quinqueradiata) from a marine fish farm.

Six strains of multidrug-resistant Stenotrophomonas maltophilia were isolated from cultured yellowtail. The strains were divided into two clusters based on the 16S rRNA genes, and all of them contained L1 metallo-beta-lactamase and L2 beta-lactamase genes. Differences in the intercluster divergence between the lactamase genes suggest that horizontal transfer of the genes occurred.

Isolation and molecular identification of Vibrio alginolyticus from cultured marine fish in farms located south provinces of Iran

Bacterial diseases are a major challenge and warning to the development of aquaculture industry. Vibriosis is caused by bacteria of the genus Vibrio, especially Vibrio alginolyticus, in warm and temperate regions, which cause severe damages to the marine fish production economy every year. The aim of the present study was to isolate and identify this bacterium from farmed marine fish with bacte...

Fatty acid profile of ewe’s milk infected with Staphylococcus spp.

Background: Mastitis in sheep caused by Staphylococcus spp. is a serious concern for dairy farming. Aims: The objective of this study was to evaluate the impact of the intramammary infection (IMI) caused by Staphylococcus spp. on the long-chain fatty acid profile and composition of ewe’s milk. Methods: The experiment was conducted in a herd of Zoslachtena Valaska sheep. Half-udder milk samples ...
