Humoral and innate response in goats immunized with vaccine against Corynebacterium pseudotuberculosis.

The objective of this study was to evaluate the humoral immune response and the innate response of goats immunized with attenuated vaccine against Corynebacterium pseudotuberculosis prepared from the strain 1002. One hundred goats were divided into 5 groups (n=20 animals/group). Each group was vaccinated as follows: G control: saline solution; G1 - 107 CFU/mL; G2 -107 CFU/mL re-vaccinated within 21 days; G3 - 106 CFU/mL; G4 - 106 CFU/mL revaccinated within 21 days.

Evaluation of ImageJ software in ultrasonic image analysis: Follicular and luteal morphological characteristics of cattle.

This study was conducted to compare the effectiveness of two methodologies in evaluating B- and Doppler-mode ultrasonic images: analysis using ultrasonic software and utilizing a computer with ImageJ software. To determine if ImageJ software utilization is an efficacious alternative to ultrasonic software device- analysis, there were comparisons of values when using the two methods for morphological and vascular characteristics of follicular dynamics and luteal function in 18 crossbred cattle. From day 8 of an ovarian dynamics synchronization treatment regimen period until the time of ovulation (Day 10), B-mode and power-flow ultrasonic cineloops were obtained every 12 h to assess follicular diameter, wall area, and wall blood perfusion area.

Correlation between the natural infection by Corynebacterium pseudotuberculosis in goats and serum progesterone levels and corpus luteum development.

Caseous Lymphadenitis (CLA) is an infectious disease that affects small ruminants, and the bacterium Corynebacterium pseudotuberculosis is its etiologic agent. This disease presents a high morbidity and a great economic impact on goat farming, leading to reduced milk and meat production and reproductive losses. The available data about the influence of C.

Effects of equine chorionic gonadotropin administered via the Baihui acupoint on follicular ovarian dynamics and the luteal function of cattle during an ovulation synchronization treatment regimen for fixed-time artificial insemination.

Objectives were to evaluate effects of a smaller than typically used dose of equine chorionic gonadotropin (eCG) during a fixed-time artificial insemination (FTAI) treatment regimen. Transrectal ultrasonic (US) examinations were conducted on dairy cows on Day 0 (D0) and the treatment regimen was initiated with administrations of an intravaginal progesterone (P) implant, estradiol benzoate (im), and prostaglandin F (PGF im). On D8, the P implant was removed and PGF and estradiol cypionate were administered to all animals.
