Interpretive Summary: A cohort of 35,200, 13-week-old, female rainbow trout at a fish farm in West Virginia was evaluated because of a two-week history of anorexia, lethargy, and a mortality rate of about 100 fish per day. Affected fish were lethargic and ataxic with bilateral exophthalmia, thin, had pale red gills and kidneys, red-tinged coelomic fluid and pale brown livers. Some were differentially pigmented bilaterally. The clinical diagnosis was bacterial or viral septicemia. The definitive diagnosis was rainbow trout fry syndrome (etiologic agent: Flavobacterium psychrophilum). The strategy for control of the outbreak was based on improving rearing conditions for the fish by reducing pathogen load in affected tanks and reducing pathogen spread among tanks. The option of treating with antibiotic-medicated feed was discussed with the farmer, but was declined. After changes were made, mortality rate declined quickly, and stopped within one to two weeks after the farm visit. Rainbow Trout Fry Syndrome (RTFS) has been extensively reported in the scientific literature as one clinical manifestation of infection with Flavobacterium psychrophilum. However, most textbooks used by aquaculture veterinarians focus on the more typical, commonly expressed form, bacterial coldwater disease. Consequently, RTFS is more prevalent that textbooks would suggest. This disease should be included on a list of differential diagnoses for septicemia in small hatchery-reared rainbow trout.
Technical Abstract: Case Description - A cohort of 35,200, 13-week-old, female rainbow trout at a fish farm in West Virginia was evaluated because of a two-week history of anorexia, lethargy, and a mortality rate of about 100 fish per day. Clinical Findings - Affected fish were lethargic and ataxic with bilateral exophthalmia, thin, had pale red gills and kidneys, red-tinged coelomic fluid and pale brown livers. Some were differentially pigmented bilaterally. The clinical diagnosis was bacterial or viral septicemia. The definitive diagnosis was rainbow trout fry syndrome (etiologic agent: Flavobacterium psychrophilum). Treatment and Outcome ¿ The strategy for control of the outbreak was based on improving rearing conditions for the fish by reducing pathogen load in affected tanks and reducing pathogen spread among tanks. The option of treating with antibiotic-medicated feed was discussed with the farmer, but was declined. After changes were made, mortality rate declined quickly, and stopped within one to two weeks after the farm visit. Clinical Relevance ¿ Rainbow Trout Fry Syndrome (RTFS) has been extensively reported in the scientific literature as one clinical manifestation of infection with Flavobacterium psychrophilum. However, most textbooks used by aquaculture veterinarians focus on the more typical, commonly expressed form, bacterial coldwater disease. Consequently, RTFS is more prevalent than textbooks would suggest. This disease should be included on a list of differential diagnoses for septicemia in small hatchery-reared rainbow trout.

Benign Parotid Masses
The parotid gland is contained in the parotid space, which is bounded superiorly by the zygoma, posteriorly by the external auditory canal, inferiorly by the styloid process, styloid muscle and great vessels. The tail of the parotid extends posteriorly over the mastoid tip and lies over the sternocleidomastoid muscle. Stensen’s duct, which is approximately 4-7-cm long, arises from the anterior border of gland. The duct exits from the lateral surface of the masseter muscle, penetrates the buccal fat pad and buccinator muscle to enter into the oral cavity, usually opposite just the second maxillary molar. Anatomically, the gland is a contiguous unit; however, surgically it is separated into a superficial and deep lobe by the facial nerve. A branch of the auricular temporal nerve, which carries postganglionic parasympathetic fibers from the otoganglion, innervates the gland. These fibers stimulate secretion. Injury to these fibers could lead to aberrant re-intervation with the skin sweat glands resulting in what is known as Fry’s Syndrome.
