    Molecular identification of some causative agents of streptococcosis isolated in farmed rainbow trout (Oncorhynchus mykiss, walbaum) in Iran (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Streptococcosis is an acute infectious disease that causes mortality in marine and freshwater aquacultures. One of the most important hosts is susceptible to the disease of rainbow trout and during the past decade its industrial production has been growing in Iran. According to FAO, Iran is among the 10 countries producing fish in the world. The most important bacteria causing Strptococcosis includes Strptococcus, Vagococcus and Enterococcus genera. But in all cases, the clinical sings are the same. More than a decade has passed since the first report of this disease in Iran and unfortunately, this disease has become the most important problems of trout production in Iran. Therefor, 72 farms were selected in 8 provinces including Mazandaran, Gilan, Lorestan, CharmahalBakhtiyari, Fars, Kermanshah, Tehran and Kokiloye-Boyer Ahmad and a total 520 moribund and apparently healthy rainbow trout (weight 50 – 200gr) were collected during summer 2008 to 2009. Fish kidney, spleen and liver samples were culture aseptically and finally 206 isolates were identified as gram positive cocci. Using conventional biochemical test, S.uberis, S.agalactiae, S.dysgalactiae, S.faecium and S.inia. Additionally, 172 from 206 isolates were confirmed as S.uberis ، S.agalactiae ، S.dysgalactiae ، S.faecium and S.inia using a PCR assay. Based on the results, the most prevalent is belong to S.uberis (isolated from 5 of 7 province), S.dysgalactiae (isolated from 4 of 7 province), S.agalactiae (isolated from 2 of 7 province) and S.faecium and S.inia (from 1 of 7 province) respectively. It is necessary to mention, S.inia was identified just to Fars and any gram positive cocci was isolated from Tehran.

    Description: Study on Viral Nervouse necrosis (isolation, characterisation and pathogenesis) in Golden grey mullet in the Caspian Sea and study of pathogenecity and possibility of transmission to the other fish species (Sturgeon fishes, Rutilus frisii kutum and reared Rainbow trout and Carp) Viral Nervous Necrosis (VNN) is a worldwide disease affecting several species of cultured marine fish. For the past two decades, betanodavirus infections that cause Viral Nervous Necrosis (VNN) have emerged as major constraints on the culture and sea ranching of marine fish in almost all parts of the world. More than forty species mainly of marine origin have been so far affected and this number is likely to rise in future following the introduction of new species and the increase of aquaculture trade. Unknown acute mortality occurred in wild golden grey mullet Lisa auratus and Liza saliens in Iranian waters of Caspian Sea in recent years. In order to isolation and confirmation of causative agents of golden grey mullet mortality in the Caspian Sea, a complementary research investigation project was designed in 2005 and approved immediately in Iranian Fisheries Research Organization (IFRO). Many diagnostic aspects such as Virology (Cell culture and Elctereone Microscopy), Hemathology, Bacteriology, Histopathology, Molecular biology (NestedRT-PCR), Heavy metals measuerment and Serology (IFAT and IHC) were employed in mentioned multidiciplinary project. About 322 moribund fish samples which revealed skin darkening, erratic swimming behavior such as spiral and belly-up at rest and high distention of swimming bladder. Suspected samples were collected from coastal capture sites in iranian north proviences in 2006 till 2009. Targets tissue such as brain and eye were removed in strile condition and then kept in -80oC frezzer for cell culture and Nested-RT-PCR. Other tissue samples from liver, kidney, intestine, stomach, gill, skin and muscle, gall bladder and gonads were taken and fixed in 10% buffer formalin and same parts fixed in glutaraldehyde 3% for histopathology, IHC and EM respectively. Cytopathic effect (CPE) was observed in those cell cultures just six days after inoculation with the dilutions of the tested 312 homogenate supernatants. CPE in monolayers of cells cultured (SSN-1 cell line) was characterised by thin or rounded, refractile, granular cells with vacuoles. Nine samples were positive in virology assay. Nested- RT-PCR was done on suspected tissue samples and supernatant of CPE positive samples and 21 tissue samples and all CPE positive samples were positive. IFAT was selected as a confirmatory method for identifying viral strains replicating on cell cultures and carried out with rabbit anti-betanodavirus serum on suspected tissue samples and some smears of CPE positive samples. Some bright points approved betanodavirus antigen and confirmed cell culture and Nested-RT-PCR findings. In fixed tissue samples widespread and massive vacuolation were observed in brain, spinal cord, retina and optical nerve. In order to confirmation of diagnostic findings , IHC was done with monoclonal antibody antibetanodavirus and some red-brown points were observed. Theses findings revealed expected viral antigens and confirmed previous results. Moreover, virus particles with 25-30 nm in diameter were visualized in infected brain and retina using positive staining in TEM. Also pathogenicity test was employed to confirm the obtained results. So Guppy fish Poecilia reticulata and sturgeon fry were used instead of the experimental host due to ease of handling and susceptibility. After 15 days post infection, guppy bathed in VNN-infected tissue culture with 104 TCID50 showed clinical signs similar to naturally infected Golden grey mullet, and the mortality rate reached up to 100% in 75 dpi. When target organs were examined by cell culture isolation, serology, and histopathology, all revealed the presence of virus in the Guppy. Suspected supernatant injected to sturgeon fry through intravitreous injection and widespread vacuolation were observed in brain and spinal cord buy IHC and Real time PCR were negative. In conclusion, with attntion to obtained results in this investigation such as ecological factors, clinical signs, histopathological, virological and bacteriological results, molecular analysis, (IHC, IFAT, PCR), TEM demonstration, serological and hematological findings, it could be confirmed that VNNV was the main causative agent for disease outbreak in Golden grey mullet in Southern coastline of Caspian Sea.

    Description: This study was conducted for the first time and the effects of probiotic bacteria isolated from the gut of Rainbow trout (Oncorhynchus mykiss). In the first step, after the purification of the isolated bacteria, probiotic properties in vitro was assessed with injection to healthy fish and challenge with three species of pathogenic bacteria in culture media. The second phase of the bacteria isolated in 5 treatments (log 7, 8 and 9 of the lactic bacteria (LAB), Vibrio sp and Pseudomonas sp) and a control treatment on growth and survival, hematological parameters (RBC and WBC cells), immunology and physiology parameters tested during the 60 days of the above parameters after 30 and 60 days and finally at the end, the final assessment was Streptococcosis resistance in fish. The results showed that the isolated bacteria were able to enhance the growth parameters (weight, feed conversion, feed fat, protein efficiency ratio and specific growth rate) and survival. The results showed that log 8 LAB was significant difference with other treatments and control. When using log 8 LAB and Vibrio, the MCV, MCH and MCHC were decreased with no significant difference. The log 8 has the greatest effect on the amount of liver enzyme (AST), IgM and complement component C3, and had significant difference with other treatments. The challenge examination to Streptococcus iniae showed the highest survival in treatments with log 8 (96.66%), and Vibrio (93.33%) and then subjected to other treatments and control are also the least survival (25.38%). The conclusion of that study is the first probiotic properties of bacteria isolated from trout to changes in quality indicators are in particular the LAB bacteria and the second log 8 of LAB had significant positive of changes development and safety, and the fish are resistanted against Streptococcosis.

    Description: Over the past few years, the syndrome of streptococcosis has been associated with outbreaks in rainbow trout (Oncorhynchus mykiss, Walbaum) and caused significant economic losses in the aquaculture industry in Iran. The main purpose of this work was molecular identification of some causative agents of streptococcosis in rainbow trout. A total of 520 samples were collected from the head kidney of diseased fish (weight, 50_200g) in 72 farms of 8 provinces in Iran, during 2008 to 2009. Bacterial isolates representing morphology and biochemical profiles of Streptococcus spp. were further confirmed by polymerase chain reaction (PCR). DNA extraction was carried out from a single colony by using the extraction promega kit following the conditions described by the supplier. The PCR assay was developed based on the 16S rRNA and glucose kinase genes of Streptococcus spp. for the rapid and specific detection and identification of this pathogen from different sources. Approximately 40% of specimens were infected to Streptococcus spp. Consequently, five pathogenic species have been identified, including S. iniae in Fars province, S. faecium in Mazandaran province, S. agalactiae in Gilan and Mazandaran provinces, S. dysgalatiae in Lorestan, Kohgiluyeh and Boyerahmad, Gilan and Kermanshah provinces and S. uberis, which was common in all provinces (except Mazandaran and Lorestan). The dominant species (based on important species index) were S. uberis, S. dysgalactiae and S. agalactiae, respectively.

    Description: Mnemiopsis leidyi (Comb Jelly) is an exotic species which has not been reported from the Caspian Sea till 1999, but it was observed and reported from the southern coasts of Caspian Sea in 1999. Invasion of the Mnemiopsis leidyi to the Caspian Sea pelagic ecosystem has been one of the main difficulties in the past decade. Mnemiopsis leidyi has been brought from the Black Sea to the Caspian Sea by ballast water of ships and it has settled in the southern Caspian Sea through the time. There is a little information regarding the microbial flora in comb jelly but a large number of comb jelly carry natural flora and pathogens located in the coastal waters such as Aeromonas and Vibrio. However, it might have been entered into the Caspian Sea many years ago, but it has recently caused excessive reduction in kilka fish stocks because it is considered as a food competitors for them. The comb jelly may also carry some new microorganisms like parasites and microbial flora to the Caspian Sea. This study was carried out to investigate the parasites and bacterial flora of B. ovata and M. leidyi as probable dangers for the Caspian Sea ecosystem.
