Sixteen multiparous Holstein cows were allotted randomly to four groups of four cows each. Cows in 1 and 2 were uninfected. Those in 3 received 60,000 and those in 4 received 120,000 Sarcocystis bovicanis sporocysts per os approximately 30 days before the expected onset of lactation to produce nonclinical and clinical infections in 3 and 4, respectively. Combined stresses of infection, parturition, lactation, and high ambient temperatures caused all infected cows to develop clinical illness. Clinical signs included fever, anemia, glossitis, myositis, nasal discharge, hypersalivation, anorexia, and hind limb weakness; two cows died and two others were killed in extremis. Six cows in 3 and 4 developed high Sarcocystis-specific immunoglobulin G1 antibody. Uninfected control cows had no clinical signs and no rising concentrations of antibody against Sarcocystis antigen. When lactation began, cows were milked twice daily, and milk production was recorded for 70 consecutive days. All sarcocystis-infected cows (3 and 4) decreased feed intake and milk production compared with uninfected controls. The Wisconsin Mastitis Test on milk production compared with uninfected controls. The Wisconsin Mastitis Test on milk samples at 1, 2, 4, 8, and 12 wk of lactation did not differ among groups.

Death with trichinelliasis of a 30-year-old man who had used for food raw pork not subjected to trichinelloscopy is described. In the terminal period of the disease there was a clinical picture of ascending polyradiculoneuritis of the type of Landry syndrome which was the main clinical diagnosis. Morphological examinations revealed massive larval invasion of the voluntary muscles, trichinellous myositis, glossitis, myocarditis, meningoencephalitis, trichinellous pneumonia. The cause of death was severe toxicity, respiratory and cardiac insufficiency.

A February 2015 outbreak of highly pathogenic avian influenza (HPAI) H5N8 in a flock of commercial Pekin ducks ( Anas platyrhynchos domesticus) in California was investigated in detail. Approximately 17,349 five-wk-old ducks experienced an increased mortality from a normal of eight birds per day to 24, 18, 24, 33, and 61 birds per day, respectively, in the last 5 days prior to flock depopulation. Clinically, there was decreased water and feed consumption, and approximately 1.0% of the affected flock exhibited neurologic signs. Necropsy of five clinically ill ducks revealed pale, patchy areas on the epicardium in two birds, pale foci of necrosis in the liver of one bird, and airsacculitis in three birds. Histopathology revealed multifocal nonsuppurative encephalomyelitis, myocarditis, myositis, pancreatitis, hepatitis, and glossitis. Immunohistochemistry revealed avian influenza virus (AIV) nucleoprotein in the nucleus and cytoplasm of various cells in the aforementioned organs, as well as in the skin and feathers. Eight of the 10 sera samples tested were positive for avian influenza antibodies by agar gel immunodiffusion serology. Oropharyngeal and cloacal swabs taken from 15 birds, as well as from the lungs, livers, pancreas, and spleen, were positive for AIV by real-time reverse transcriptase (rRT) PCR. AIV was isolated and typed as Eurasian lineage HPAI H5N8, clade 2.3.4.4, by the National Veterinary Services Laboratory, Ames, IA. Extensive surveillance of birds for AIV around the 10-km zone did not reveal any additional cases. Ducks on the affected premises were humanely euthanatized by foam and composted in-house, the houses were heated to 57 C for 4 days, and swabs were taken periodically from the compost to ensure negativity for AIV by rRT-PCR. The compost and litter were then removed, and the house was pressure cleaned, disinfected, and repopulated approximately 120 days after euthanatization of the ducks.
