Abstract:: Pseudoloma neurophilia (Microsporidia) is the most common pathogen detected in zebrafish (Danio rerio) from research facilities. The parasite infects the central nervous system and muscle, and may be associated with emaciation and skeletal deformities. However, many fish exhibit subclinical infections. Another microsporidium, Pleistophora hyphessobryconis, has recently been detected in a...

Abstract:: Tolerance of adult zebrafish and efficacy of emamectin benzoate and ivermectin in eliminating Pseudocapillaria tomentosa infection were evaluated. In the tolerance study, behavioral changes, fecundity, histopathology, and mortality were evaluated for in-feed administration of emamectin (0.05, 0.10, and 0.25 mg/kg) and ivermectin (0.05 and 0.10 mg/kg). All doses of emamectin...

Abstract:: The Willamette River, one of only 14 American Heritage Rivers, flows through the most densely populated and agriculturally productive region of Oregon. Previous biological monitoring of Willamette River fish detected elevated frequencies of skeletal deformities in fish from certain areas of the lower (NP [NP], rivermile [RM] 26-55) and middle...

Abstract:: Erythrocytic inclusion body syndrome (EIBS) was artificially established in selected stocks of juvenile fall and spring chinook salmon (Oncorhynchus tshawytscha), chum salmon (0. keta), coho salmon (0. kisutch), Atlantic salmon (Salmo salar), and rainbow trout (0. mykiss). Adult spring chinook salmon were also artificially infected with the EIBS virus. Adult...

Abstract:: Atrazine (ATZ) is a selective triazine herbicide used primarily for pre-emergent weed control in corn, sorghum and sugar cane production. It is one of the most widely used herbicides in North America. Some research published over the last decade suggests that chronic exposure to environmentally relevant ATZ concentrations can adversely...

Abstract:: Detection and treatment of bacterial kidney disease (BKD) was investigated. Experiments were conducted to evaluate the quantitative, fluorescent antibody technique (QFAT) that is used to detect, identify, and quantify both typical and 'bar form' Renibacterium salmoninarum cells. Smears of kidney tissue from naturally and artificially infected salmonids, both with and...
