Streptococcosis has been defined as a hemorrhagic septicemia in many fish species especially rainbow trout. This disease causes serious economic losses due to high mortality in fish and the bacteria responsible is also considered as a zoonotic pathogen. The aim of this study was identification of different causative agents of warm water streptococcosis and evaluation of the capsule gene in Lact...

Today, childhood caries is main health related disease it affects many schooling children in countries especially developed by lactic acid bacteria. So this present the isolating 50 bacteria from different decay affected children’s Fen Dental Clinic, Tirupur Dt. The emerging LAB confirmed phenotype and genotype characterization. After, pathogen screened for production of biofilm to check resist...

One of the major threats to seabass (Dicentrarchus labrax) aquaculture sector is development vibriosis, a disease caused mainly by bacteria from family Vibrionaceae, especially Vibrio harveyi. Given relationship between abundance in surrounding environment and prevalence fish, monitoring presence V. harveyi rearing water biofilms over time may help better understand dynamics pathogen factors th...

Veronaea botryosa is a melanized mold and cause of systemic fungal infections in cultured sturgeon (Acipenser spp.). Mortality in adult female sturgeon caused by this emergent pathogen results in significant economic losses for the caviar industry. Little is known regarding environmental conditions conducive to V. botryosa infection. This study evaluated the effect of temperature on V. botryosa...

Fishes account for approximately 17% of the global animal protein intake. Fish and fishery products, however, have been documented as a carrier of food-borne pathogens. Fishes serve as a host to a variety of parasites including Salmonella.Salmonella, usually, is not a fish pathogen, rather the consumption of Salmonella contaminated feed and water causes this infection. Smoked fishes serves as a...

Lactococcus garvieae infection in cultured Nile tilapia, Oreochromis niloticus (L.), and pintado, Pseudoplathystoma corruscans (Spix & Agassiz), from Brazil is reported. The commercial bacterial identification system, Biolog Microlog, confirmed the identity of L. garvieae. Infectivity trials conducted in Nile tilapia using Brazilian Nile tilapia L. garvieae isolates resulted in a median lethal ...

Ribotyping and RAPD profiling of a collection of 18 Streptococcus parauberis strains isolated from diseased turbot in Galicia (NW Spain) was performed in order to analyze the possible genetic variability within this bacterial fish pathogen. In addition, the value of this technique for intraspecific classification and epidemiological studies was evaluated. Ribopatterns of DNA digested with three...

Streptococcus dysgalactiae is an emerging pathogen of fish. Clinically, infection is characterized by the development of necrotic lesions at the caudal peduncle of infected fishes. The pathogen has been recently isolated from different fish species in many countries. Twenty S. dysgalactiae isolates collected from Japan, Taiwan, Malaysia and Indonesia were molecularly characterized by biased sin...

Neorickettsia helminthoeca is an obligate intra-cytoplasmic bacterium that causes salmon poisoning disease (SPD), an acute, febrile, fatal disease of dogs. The complex life-cycle of this pathogen involves stages in an intestinal fluke (Nanophyetus salmincola), a river snail (Oxytrema silicula), in fish, and in fish-eating mammals. This complexity has created confusion with respect to the variou...
