Experimental mycobacteriosis in striped bass Morone saxatilis.

A unique Mycobacterium species isolated from an epizootic of striped bass (Morone saxatilis).

We isolated a Mycobacterium sp. resembling Mycobacterium marinum and M. ulcerans from diseased striped bass (Morone saxatilis) during an epizootic of mycobacteriosis in the Chesapeake Bay. This isolate may represent an undescribed Mycobacterium species, based on phenotypic characteristics and comparative 16S rRNA gene sequence.

Mycobacteriosis-associated mortality in wild striped bass (Morone saxatilis) from Chesapeake Bay, U.S.A.

The striped bass (Morone saxatilis) is an economically and ecologically important finfish species along the Atlantic seaboard of the United States. Recent stock assessments in Chesapeake Bay (U.S.A.) indicate that non-fishing mortality in striped bass has increased since 1999, concomitant with very high (>50%) prevalence of visceral and dermal disease caused by Mycobacterium spp. Current fisher...

Quantifying the Interactive Effects of Hypoxia, Temperature, and Mycobacteriosis on Striped Bass (Morone saxatilis), and Their Impact on the Energetics and Ecology of These Fish

Isolation and characterization of mycobacteria from striped bass Morone saxatilis from the Chesapeake Bay.

Mycobacteriosis in striped bass Morone saxatilis of Chesapeake Bay, USA, was first diagnosed in 1997 based on the presence of granulomatous inflammation and acid-fast bacteria in skin and spleen. To confirm histopathology, bacteriological detection and identification of mycobacteria were begun using splenic tissue from fish with and without skin ulcerations. On the basis of initial studies usin...

Comparative analysis of mycobacterial infections in wild striped bass Morone saxatilis from Chesapeake Bay.

During an ongoing epizootic of mycobacteriosis, wild striped bass Morone saxatilis from Chesapeake Bay were analyzed using 3 methods for detection of either mycobacterial infection or associated granulomatous pathology. The specific detection techniques, which utilized aseptically collected splenic tissue, were histology, quantitative culture and nested PCR. Based on analysis of 118 samples, de...

Transcriptome annotation and marker discovery in white bass (Morone chrysops) and striped bass (Morone saxatilis).

Striped bass (Morone saxatilis) and white bass (Morone chrysops) are the parental species of the hybrid striped bass, a major U.S. aquaculture species. Currently, genomic resources for striped bass, white bass, and their hybrid lag behind those of other aquaculture species. Current resources consist of a medium-density genetic linkage map and a well-annotated ovarian transcriptome. A well-annot...
