  Fish and other aquatic animals, directly and indirectly, can be contaminated with Listeria monocytogenes and consequently, fish and their products are considered a carrier for this bacterium. The present study investigated the contamination of farmed rainbow trout and common carp with this bacterium as well as the phylogenetics of the isolates. A total of 50 samples of farmed fish were obtained from local fish supply centers in Shahrekord City from July to September 2018. Based on the molecular experiments, 18 (36%) of the 50 studied samples were contaminated with L. monocytogenes as 26% and 10% of the isolates were found in trout and carp, respectively. From 18 isolates, 12 samples (66.66%) belonged to serotype 4b, one belonged to serotype 1/2a and the other 5 samples belonged to serotype 1/2b. According to the results of the present study and regarding the importance of the bacteria in terms of public health, continuous and accurate hygienic monitoring seems to be necessary.

  Seafood has found its way into eating habits of consumers. However, it can be accompanied with some hazards such as transmission of pathogenic bacteria. The origin of disease can be either a fish pathogen or a secondary contamination. Vibrios are of the important bacteria which are naturally found in the environment and in the aquatic animals' body as microflora and results in vibriosis if ingested raw or undercooked. The most important species are Vibrio parahaemolyticus, V. Cholera, V. vulnificus and V. alginolyticus. Although vibrio species are distributed worldwide, but it seems that they are more prevalent in some areas due to nutritional habits. This article reviews important species, source of infection and the previous reports. Manuscript profile

  3 - Bacterial zoonotic disease from fish: a review
  Mehdi Raissy
  Zoonoses involving transmission of disease and biotoxin producing agents from fish to humans have been documented in the literature mostly including bacteria, biotoxins and parasites. The list of potential fish-borne zoonoses is quite large. Twenty six infectious agents More

  Zoonoses involving transmission of disease and biotoxin producing agents from fish to humans have been documented in the literature mostly including bacteria, biotoxins and parasites. The list of potential fish-borne zoonoses is quite large. Twenty six infectious agents are discussed in this review and there are also many other infectious organisms of fish origin that have not been reported but have the potential to infect and harm human. The status of the human host immune system plays a vital role in the severity of the disease. The major exposure routes include ingestion and introduction of organisms through open wounds or abrasions. More specifically, ingestion includes consumption of raw or under-cooked infected fish tissue, ingestion of fish tissue contaminated with feces from infected fish. Overall 46.15 % of fish-borne zoonoses are transmitted orally which are mostly helminthic diseases are caused by Trematodes, Cestodes and nematodes. Yet these zoonoses are responsible for large numbers of human infections around the world. Ingestion of water harboring infectious organisms with 23.07 % and Dermal exposure includes introduction of infectious agents into open wounds or abrasions through handling infected fish or infected water with 19.23 % are other transmission ways and importantly 15.38 % of fish-borne zoonoses are transmitted by more than one way. Distribution, epidemiology, clinical aspects, and the research needed for improved risk assessments, clinical management and prevention and control of these important diseases are reviewed.

  4 - Evaluation of antibacterial effects of some plant extracts and essential oils against Vibrio parahaemolyticus
  Mehdi Raissy Ali Daghaghelelh Mojtaba Alishahi Mehdi Rahimi
  In this study the antibacterial effects of ethanolic extract of eight medicinal plants (Artemisia aucheri, Satureja bachtiarica, Tanacetum parthenium, Cuminum cyminum, Salvia officinalis, Achillea kellalensis, Stachys lavandulifolia, Myrtuscommunis) and the essential oi More

  In this study the antibacterial effects of ethanolic extract of eight medicinal plants (Artemisia aucheri, Satureja bachtiarica, Tanacetum parthenium, Cuminum cyminum, Salvia officinalis, Achillea kellalensis, Stachys lavandulifolia, Myrtuscommunis) and the essential oil of Satureja bachtiarica, Artemisia aucheri, Tanacetum parthenium, Cuminum cyminum, Achillea kellalensis, Myrtuscommunis on Vibrio parahaemolyticus were evaluated. Standard tube dilution method was used for evaluation of Minimum Bactericidal Concentration value (MBC) and Minimum Inhibitory Concentration value (MIC) of each plant. Then inhibitory zone of bacterial growth for each plant was also measured and compared to positive and negative control. The results showed that the extracts of Satureja bachtiarica had the highest antibacterial effects on V. parahaemolyticus with the inhibitory bacterial growth zone of 15 mm. The extract of Tanacetum parthenium and Cuminum cyminum were also effective with the inhibitory bacterial growth zone of 14 and 11.67 mm against V. parahaemolyticus. Other herbal extract showed no antibacterial effects. The results revealed the higher antibacterial effects of essential oils comparing to the extracts and the highest antibacterial effect were belonged to Satureja bachtiarica, Tanacetum partheniumand Cuminum cyminum. It can be concluded that regarding to high antibacterial effect of Satureja bachtiarica, Tanacetum parthenium and Cuminum cyminum, they can be used in elimination of V. parahaemolyticus.

  Lactococcosis which is caused by Lactococcus garvieae is now widespread. This species is categorized in zoonosis agents and is able to cause endocarditis especially in immunosuppressed persons. This study was done to detect Lactococcus garvieae in cultured rainbow trout meat collected from retail market and to evaluate the virulence of the isolates. A total of 90 fresh fish were randomly selected and were transferred to the laboratory in appropriate conditions. After collecting meat samples, the bacteria were investigated by culture on BHIA and standard biochemical tests. The results were confirmed by PCR. Presence of virulence gene in the isolates were studied and the results revealed that 4 isolates of a total of 9 collected isolates harbored cap virulence gene (44.4%). According to the results, rainbow trout meat can be contaminated with Lactococcus garvieae which is a potential danger for consumers. However, it depends on the nutritional habits and methods of reservation. Manuscript profile

  A high number of parasites can infect fish, and some can be transmitted to humans. Human or fish-eating mammals can be the main host of these parasites. Today, more than 40 species of fish-borne parasites have been identified, causing disease in humans. These parasites can be classified as protozoa, trematode, Cestoda, Nematoda and Acanthocephala. Infection in humans usually occurs following the consumption of larvae-infected meat. The possibility and the rate of infection directly relate to different criteria, including the fish consumption rate, level of hygiene, feeding habits, and methods of cooking or processing. In this article, having discussed the fish-borne parasites, the reports of zoonotic parasites from fish in Iran have been discussed. Manuscript profile
