Experimental infection of calves with seven serotypes of Epizootic Hemorrhagic Disease virus: production and characterization of reference sera.

Vet Ital 2019 Dec 31;55(4):339-346. Epub 2019 Dec 31.

UMR Virologie, INRA, Ecole Nationale Vétérinaire d'Alfort, laboratoire de santé animale d'Alfort, ANSES, Université Paris-Est, 94700 Maisons-Alfort, France.

The aim of this study was to produce reference sera against the seven serotypes of Epizootic hemorrhagic disease virus (EHDV‑1, EHDV‑2, EHDV‑4, EHDV‑5, EHDV‑6, EHDV‑7, and EHDV‑8). In a high containment unit, seven Prim 'Holstein calves were inoculated at day 0 (D0) with the selected strains (1 EHDV serotype per calf ). Blood samples (EDTA and whole blood) were periodically taken from D0 until the end of the experiment (D31). Read More

Mechanisms of lipid mobilization towards egg formation in broiler breeder hens using stable isotopes.

Poult Sci 2017 Feb 21;96(2):383-387. Epub 2016 Jul 21.

University of Arkansas, Center of Excellence for Poultry Science, Fayetteville 72701

The contribution of dietary, mobilized, or newly synthesized fatty acids in yolk formation at different periods of egg production was determined. In an initial experiment, a single dose of C-linoleic acid was administered to pullets at the onset of egg production and their presence in follicles determined over the subsequent 10 days. In a second experiment, pullets were fed a daily 15 mg dose of U-C-glucose beginning 2 wk prior to sexual maturity through the end of the experimental period. Read More

Power and pulsed Doppler evaluation of ovarian hemodynamic changes during diestrus in pregnant and nonpregnant bitches.

Theriogenology 2013 Jan 15;79(2):219-24. Epub 2012 Nov 15.

Department of Pathology Diagnostic and Veterinary Clinical, Faculty of Veterinary Medicine, University of Perugia, Perugia, Italy.

The aim of the study was to further characterize the relationship between hemodynamic changes in the ovary and luteal function in pregnant and nonpregnant bitches. Fourteen German Shepherd bitches were monitored three times a week from the first day of cytological diestrus (D1) until parturition or the end of diestrus (progesterone <2 ng/mL) by color Doppler, pulsed wave spectral Doppler, and power Doppler (PD) ultrasonography. By means of PD the total number of color pixels were calculated. Read More

The effect of immunization route on rat serum and tear antibody responses to Chlamydia trachomatis.

Reg Immunol 1993 Mar-Apr;5(2):114-9

Department of Clinical Sciences, College of Veterinary Medicine, Kansas State University, Manhattan, KS 66506.

The effect of immunization route on the kinetics of serum and tear antibody responses to Chlamydia trachomatis was studied in a rat model. Rats received Chlamydia trachomatis serovar C/TW elementary bodies for two immunization cycles by ocular topical (OT) application or subconjunctival (SC) injection and in a second experiment for three immunization cycles by either OT application, gastrointestinal intubation (GI), or intraperitoneal injection (IP). Serum IgG and tear IgA antibodies to whole elementary bodies were measured sequentially following the secondary (2 degrees) and tertiary (3 degrees) immunization cycles. Read More
