Lung, trachea and bursa of Fabricius were collected from broilers between 14 and 49 days of age from eight flocks with varying levels of mortality and air sac disease (air sacculitis often accompanied by pericarditis and perihepatitis). These tissues were screened for the presence of Cryptosporidia sp. Bursal cryptosporidial infection was present in two(More)
One-day-old and 7-day-old specific-pathogen-free chickens were orally infected with a field isolate of Salmonella enteritidis phage type 13A. Chickens were sequentially euthanatized at various intervals until 42 days of age, and selected tissues were collected for microscopic evaluation. Eleven of 53 chickens (21%) infected at 1 day of age and 2 of 28(More)
Banked serum samples collected from an industry-wide serologic survey of eighteen Delmarva broiler flocks conducted in 1985 were evaluated for the presence of Cryptosporidium- specific antibodies in an indirect enzyme-linked immunosorbent assay (ELISA). Evaluation of sera collected at 49-days posthatch showed that 38% of the broiler flocks were(More)
One- and 7-day-old specific pathogen-free chickens were artificially infected with a field isolate of Salmonella enteritidis, phage type 13A. At intervals up to 42 days of age, birds were killed and liver, lung, spleen, brain, yolk sac, testis or ovary, duodenum, jejunum, ileum, caecum and colon collected for culture. In chickens infected at one day of age(More)
Reproductive and developmental toxicities of zinc supplementation in F(0) rats and F(1) progeny were examined. Rats were treated by gavaging with zinc chloride (ZnCl(2)) at 0.0, 7.5, 15 and 30 mg/kg-d. ZnCl(2) treatment was associated with deficient energy imbalances, reduced number of live pups/litter, decreased live birth index, increased mortality and(More)
BACKGROUND There are limited data on the effectiveness of skin cancer prevention education and early detection programs at beaches. OBJECTIVES We evaluate 4 strategies for addressing skin cancer prevention in beach settings. METHODS This prospective study at 4 beaches included 4 intervention conditions: (1) education only; (2) education plus biometric(More)
A mature cockatiel was presented to the teaching hospital with acute, severe dyspnea and a markedly enlarged abdomen. The bird died 2 hours after admission and was necropsied. A 3-cm egg yolk was present in the abdominal cavity and caused cranial displacement of the abdominal viscera. Death occurred acutely and was probably due to severe respiratory(More)
Testicles were collected from 33 male Japanese quails older than 3 years. Three of these quails (9.1%) had one or two large neoplastic testicles. These testicles were 2-5 times normal size, round, and firm, with cystic spaces of various sizes. Microscopically, there was marked intratubular Sertoli cell proliferation and various-sized cystic spaces filled(More)
