ABSTRACT Aims Clinostomid metacercariae infect a wide range of freshwater fish species, posing zoonotic risk to human health when consumed raw or undercooked, potentially leading Halzoun disease. Although these parasites are generally considered threat in Asian countries, they also present various regions Türkiye and have been found 12 different species commonly local cultures. However, their presence has not reported the endemic Anatolian fish, Alburnus escherichii . This study aims...

In this manuscript, thirty yellow-pigmented Gram-positive bacteria were isolated from natural intestine microflora and sea water around the marine cage of a rearing tank common dentex (Dentex dentex), in Aegean Sea on Turkish coast characterized. Eighteen isolates assigned to species Micrococcus luteus, other twelve Bacillus marisflavi. Eight representative strains, six B. marisflavi two M. chosen for further 16S rDNA analyses. A pathogenicity assay bacterial strains was carried out rainbow...

This paper describes systemic mycobacteriosis caused by Mycobacterium marinum, in farmed meager (Argyrosomus regius), Turkey. Infected two year old fish showed signs of stunted growth, emaciation, slight ascites and exophtalmia, pale gills significant mortalities. Only one sample hemorrhagic ulcerative skin lesions at the base caudal fin. Internal multifocal white colored granulomas spleen, kidney, liver were observed. Ziehl-Neelsen (ZN) Gram stained fresh squash mounts revealed ZN positive...

Abstract Bee venom (BV) is a rich source of secondary metabolites from honeybees ( Apis mellifera L.). It contains variety bioactive ingredients including peptides, proteins, enzymes, and volatile metabolites. This study investigated the antibacterial effects bee obtained honey bees L.) against bacterial fish pathogens, such as Lactococcus garvieae (Lg1, Lg2, Lg3), Vibrio anguillarum (Va1, Va2, Va3), Yersinia ruckeri (Yr1, Yr2, Yr3), Aeromonas hydrophila Ah1, Ah2, Ah3) expression levels on...

Transmission electron microscopy (TEM) used monitor translocation bacterial pathogens which can enter host through gut. A total 260 samples larvae at different feeding stages were examined, 15 healthy 50 juvenile sampled over a 2-year period. Bacterial isolates (n=433) fish their environments identified by biochemical methods; 75% them...

This study was carried out to detect Lactococcus garvieae from experimentally infected rainbow trout (Oncorhynchus mykiss, W.) using bacteriological, serological, and histopathological techniques. Rainbow were with two strains (L1 L2) by intraperitonal injection. These caused bilateral exophthalmia periocular hemorrhage, corneal opacification, darkening of the skin, strong internal congestion in visceral organs, enlargement spleen trout. The L. re-isolated fish groups identified standard...

Haemolysin genes (hly1, hly2, hly3) are functional genetic determinants of virulence in bacterial pathogenesis.In this study, the presence hly was investigated Lactococcus garvieae, previously recovered from infected rainbow trout (Oncorhynchus mykiss) commercial fish farms.Although bacteriological phenotypic tests failed to correctly identify six isolates at species level, amplification products (1100 bp) partial 16S rRNA gene region and their nucleotide homology confirmed that 21 isolates,...

This study, it was aimed to examine the clinical, hematological, and histopathological aspects of lactococcosis induced in European sea bass (Dicentrarchus labrax), which experimentally infected with Lactococcus garvieae. For this purpose, infection intraperitoneally L. garvieae strain (108 CFU/mL), blood samples were collected from fish on different days (6, 18, 26, 31, 36, 44, 48th) infection. The morphological structures, erythrocyte leukocyte count, hematocrit value, sedimentation rate,...

The aim of this study was to diagnose the bacterial pathogens moribund rainbow trout (Oncorhynchus mykiss) reared in a dam-lake cage farm located Black Sea Region Turkey and determine their antibiotic susceptibility histopathological effects by using routine bacteriological, molecular methods. Besides possibility use two probiotics against these for prevention further infections investigated. In study, mixed infection case caused Frigoribacterium faeni Lactococcus garvieae diagnosed samples...

The effects of GroBiotic®-A supplementation on growth performance, body composition, liver and intestine histology in European seabass (Dicentrarchus labrax) juveniles were evaluated. commercial was added to diets at four different levels (0, 1, 2 3%), three replicates fed 4 times a day (9:00, 11:30, 14:00, 16: 30 hours) for 60 days as ad libitum. Total 480 with starting weight 1.40±0.08 g randomly stocked into 12 tanks volume 1 m3. At the end study, changes observed weight, feed conversion...

Objective: In this study, the diagnosis of infection caused by Vibrio anguillarum in cultured rainbow trout (Oncorhynchus mykiss), Turkey using bacteriological, histopathological and immunohistochemical methods was attempted.Materials Methods: 15 samples showing signs disease were investigated bacteriological histopatological methods.Results: Because physiological biochemical characteristics bacteria growing on medium, these isolated identified as V. anguillarum. As a result histopathologic...
