Summary This study was conducted to estimate the prevalence of Salmonella spp. and their antimicrobial susceptibilities on poultry swine farms, sampled in 2 regions Central Vietnam. A total 67 farms 46 were a period 5 months (from September 2012 January 2013). prevalent 46.3% 71.7% respectively. Altogether, 99 non‐typhoidal isolated most common serovars Weltevreden (19%), followed by Typhimurium (12%) 4,[5],12:i:‐ (11%). Overall, 71 (72%) isolates resistant at least one 14 agents tested....
Melanomacrophage centres (MMCs) are aggregates of macrophages accumulating various pigments. They have been proposed as an indicator fish immune response. Blood flukes common parasites in farmed fish. Two cohorts wild Southern Bluefin Tuna (Thunnus maccoyi) were examined at transfer, before treatment against blood (pre-treatment) and harvest. MMCs assessed histological sections using image analysis, while Cardicola forsteri orientalis infection severity was determined qPCR, count adult heart...
Trichodinids are parasites generally found on gills and skin of a broad number aquatic animals. Only small endozoic species has been reported from the urinary tract, intestine urogenital system in some fish, amphibians molluscs. This is first report presence trichodinids spleen, kidney liver shorthorn sculpin (Myoxocephalus scorpius). In present study, displayed typical morphological characteristics with narrow blades straight rays adhesive disc denticles. The were observed at relatively...
Abstract There are limited reports of infectious agents affecting Australian cowtail stingrays. In the present study, a new species ascaridoid nematode belonging to genus Mawsonascaris is described. The most distinct characteristic features were observed in females (the presence polar spine eggs and flap‐like projection vulval area). An identification key for spp. provided. Additionally, internal transcribed spacers (ITS) sequences obtained species. Alignment ITS sequence specimens study...
For many years, the sculpin has been utilized as a sentinel monitoring species for anthropogenic impacts on marine environment. To further develop its potential screening model body burden of several trace elements, including cadmium (Cd), copper (Cu), mercury (Hg), lead (Pb) and selenium (Se), were investigated. In addition, histopathology in shorthorn sculpins (Myoxocephalus scorpius; n = 20) fourhorn quadricornis; 10) examined at three sites around Scoresby Sound settlement Central East...
There is inadequate morphological nomenclature and definition of organ pathology when using wild fish in biomonitoring environmental pollution. The aim this investigation was to provide a guide that assesses histology Shorthorn (Myoxocephalus scorpius) Fourhorn quadricornis) sculpins obtained from study these two species as bioindicator organisms evaluate impact attributed dumpsite located East Greenland. Specific histopathological lesions were quantified on the basis Bernet et al. all...
Suckermouth armored catfish (Pterygoplichthys disjunctivus) is one of the most widespread invasive species in Vietnam. However, it relatively unknown how underwent its divergent adaptations to varying local conditions and habitat types, an understanding which essential for managing invasion We addressed this by analyzing a large number fish (662 samples) collected lotic (Dinh River) lentic (Suoi Trau Reservoir) habitats southern Vietnam during year. The allometric growth patterns estimated...
Myxospores discovered floating free in the bile of marine fishes from south-central coast Vietnam were identified using morphological and molecular methods, leading to description 2 new species. Ceratomyxa chauvanminhi n. sp. was detected 16% (8/50) cultured barramundi Lates calcarifer (Bloch) specimens, sekoi found 20% (5/25) wild largehead hairtail Trichiurus lepturus Linnaeus specimens. The spores C. are very shallowly ovoid, slightly crescent shaped, 11.5 ± 0.5 (10.7-12.4) μm thick, 5.8...
Abstract Handfish (Family Brachionichthyidae) is the most threatened marine teleost fish family, however, there little information on handfish health. We reviewed results of submissions mortalities from captive and bred spotted ( Branchionichthys hirsutus (Lacepède, 1804)) red Thymichthys politus (Richardson, 1844)) a public aquarium January 2018 to February 2024. Seventeen cases for (comprising 33 individuals) five (one individual each) were submitted mortality investigation. In 2018–2019,...
