herbal medicinal products have attracted significant research interest in recent years. considering the efficiency of algae products in controlling pathogenic bacteria and also easy access to large resources of algae, this study was conducted to evaluate the effects of methanolic, chloroformic and aqueous extracts of gracilaria salicornia against aeromonas hydrophila , a heterotrophic, gram-neg...

Fish translocations are an important tool in fisheries management, yet translocating fish carries the risk of introducing unwanted pathogens. Although pathogen screening can be a useful tool for managing the risk associated with fish translocations, screening cannot eliminate this risk. This paper addresses these problems by demonstrating that two elements must be considered when designing effi...

Fish farming is an important industry along the Norwegian west coast. This industry provides labor opportunities and financial income in areas that are often thinly populated. Fish are subject to diseases carried by pathogens. The value of the fish that are lost due to disease is worrisome, and emergent diseases continue to pose a severe challenge to the aquaculture industry. We have built an a...

In this study, we have investigated 201 gastric biopsy specimens obtained from dyspeptic patients for the presence of Helicobacter pylori. By means of fluorescent in situ hybridization (FISH) with rRNA-targeted fluorescence-labeled oligonucleotide probes specific for H. pylori, this pathogen was detected in 63 biopsy specimens. By using conventional culturing, H. pylori was isolated from 49 of ...

A nested reverse transcriptase (RT) PCR assay detected mRNA of the salmonid pathogen Renibacterium salmoninarum in samples of RNA extracts of between 1 and 10 cells. Total RNA was extracted from cultured bacteria, Atlantic salmon (Salmo salar L.) kidney tissue and ovarian fluid seeded with the pathogen, and kidney tissue from both experimentally challenged and commercially raised fish. Followin...

Ecological changes affect pathogen epidemiology and evolution and may trigger the emergence of novel diseases. Aquaculture radically alters the ecology of fish and their pathogens. Here we show an increase in the occurrence of the bacterial fish disease Flavobacterium columnare in salmon fingerlings at a fish farm in northern Finland over 23 years. We hypothesize that this emergence was owing t...

Fish tank or swimming granuloma caused by Mycobacterium marinum is an opportunist pathogen commonly found in aquatic environments. We present a 16 year-old boy with frequent exposure to aquarium water who had several nodules (sprotrichoid forms) on his right hand. Pervious studies showed that fish tank granuloma is a rare skin infection (0.27 per 100,000 population in one year). However, t...

streptococcus iniae has emerged as an important fish pathogen over the last decade in farmed rainbow trout in iran. the main objective of this study was to evaluate the pathogenicity of s. iniae in poecilia reticulata . atotal of 60 apparently healthy p. reticulata were obtained from ornamental fish pet store and injected intraperitoneally with 1.5×10 6 cfu of bacteria. for 14 days after challe...
