The dusky grouper (Epinephelus marginatus) is a widely distributed epinephelid species. It inhabits the eastern and southwestern Atlantic Ocean, western Indian Mediterranean Sea. Populations of this species have faced significant threats due to various anthropogenic activities, including environmental degradation intensified fishing effort. To address declining populations, management strategies involving release hatchery-reared juveniles been implemented. This study evaluated success pilot...
Objective To determine serologic prevalence of Sarcocystis neurona , Toxoplasma gondii and Neospora caninum in horses Brazil. Design Prevalence survey. Animals 101 Thoroughbreds Procedure Blood samples were obtained from tested for serum antibodies against S by use an immunoblot procedure with culture-derived merozoites as antigen, T N a modified agglutination test formalinpreserved tachyzoites mercaptoethanol. Results Antibodies detected 36 16 horses, respectively. Cross-reactivity between...
Serum samples were collected from 582 horses 40 stud farms in the State of São Paulo and tick (Acari: Ixodidae) infestations evaluated on them.Serum subjected to complement fixation test (CFT) a competitive inhibition ELISA (cELISA) for Babesia caballi Theileria equi.Logistic regression analyses performed construct multivariate models that could explain dependent variable (horses positive B. or T. equi) as function independent variables (presence abundance each one species found farms).A...
Neobenedenia melleni (MacCallum, 1927) (Monogenea) is a widespread pathogen in marine teleost cultures all over the world. The present paper reports this parasite species farmed cobia (Rachycentron canadum) Brazil, for first time. Some comments on preventive actions avoiding disease are made.
Isolates of Sarcocystis falcatula-like organisms from South American opossums were characterized based on biological and morphological criteria. Sporocysts intestinal scrapings 1 Didelphis marsupialis 8 albiventris São Paulo, Brazil, fed to captive budgerigars (Melopsittacus undulatus). Budgerigars sporocysts all 9 isolates became ill S. schizonts identified in sections their lungs by immunohistochemical staining. cultured D. 3 albiventris. The 33/54 locus amplified polymerase chain reaction...
The North American opossum, Didelphis virginiana, is a definitive host for at least 3 species of Sarcocvstis: S. falcatula Stiles 1983, neurona Dubey, Davis, Speer, Bowman, de Lahunta, Granstrom, Topper, Hamir, Cummings, Suter 1991, and speeri Dubey Lindsay 1999. In order to identify Sarcocystis in the South D. inarsupialis, sporocysts from intestines naturally infected opossum (D. marsupialis) Brazil were fed 4 gamma-interferon knockout (KO) mice, nude mouse, 2 budgerigars (Melopsittacus...
Sea lice (copepods) are widespread pathogens in marine teleost cultivation around the world. The sea louse Caligus mutabilis Wilson, 1905, is recorded here for first time sea-farmed gag grouper, Mycteroperca microlepis, Brazil.
(With 1 figure)The family Caligidae, mainly Caligus and Lepeophtheirus species are widespread sea lice copepods that parasitize body surface, cavity of the mouth, gills, operculum teleosts elasmobranchs ( Ho et al., 2001 ). These parasites erode fishes epithelium leading secondary bacterial infections (Sanches 2012). The Caligidae one most major health pathogens for farmed fish. In Northern Hemisphere salmon louse salmonis (Kroyer, 1838) alone is responsible commercial losses in excess € 180...
Algumas das principais doenças em equinos estão relacionadas aos membros locomotores, as quais podem advir de traumas ou distúrbios ósseos principalmente durante a fase crescimento. No Estado São Paulo, o desenvolvimento pastagens com características tropicais, alterações sazonais e tendência à grande concentração animais pequenas propriedades resultam, frequentemente, no aparecimento distrofias ósseas, muitas vezes subclínicas, que depreciam valor econômico dos limitam sua capacidade...
