The aim of this study was to evaluate the protective efficacy of the CIRCOQ porcine circovirus type 2 (PCV2) subunit vaccine in piglets with high maternally derived antibodies (MDAs) against disease caused by natural infection with PCV2d. A total of 130 weaned, 21-day-old healthy pigs was allocated into 3 trial groups. The signs of respiratory disorder were higher in unvaccinated pigs than in vaccinated pigs at 13 to 17 weeks old (P < 0.05), 18 to 22 weeks old (P < 0.001), and 23 to 27 weeks old (P < 0.01). The unvaccinated pigs had an early rate of dermatitis at 8 to 12 weeks old (10.0%), 13 to 17 weeks old (30.0%), 18 to 22 weeks old (46.7%), and 23 to 27 weeks old (33.3%), while there were no cases of dermatitis in vaccinated pigs. There was a significant difference (P < 0.05) in the mortality of pigs in the unvaccinated group and the 2-dosed vaccinated group. PCV2 viremia was detected in the blood and peaked at 105 days old in both unvaccinated pigs (Ct-adj = 8.40) and pigs vaccinated with 1 dose (Ct-adj = 6.37), while no detectable PCV2 virus was found in the blood of pigs vaccinated with 2 doses. At 77 and 105 days old, the PCV2 viremia load (Ct-adj) of unvaccinated pigs and those vaccinated with 1 dose was significantly higher (P < 0.05) than that of the 2-dosed vaccinated pigs. The body weight (BW), average weight gain (AWG), and average daily gain (ADG) in both groups of vaccinated pigs were significantly higher (P < 0.05) than those of unvaccinated pigs. The study vaccine was significantly efficacious in protecting vaccinated pigs against clinical symptoms, blood viral load, and mortality, as well as improving productivity, compared with unvaccinated pigs.

The aim of this study is to determine the incidences of Malassezia infection and flea allergy in dogs with dermatitis complaints which were brought to veterinarians for examination in Ankara and Kırıkkale provinces. Materials and Methods: The material for this study consists of 40 pet dogs of different breeds genders and ages found in Ankara and Kırıkkale provinces of Turkey. Malassezia examination was conducted by staining smear samples taken with the acetate band method with Modified Wright’s Stain method. Flea existency examination was performed by using a flea comb.Out of the 40 dogs with dermatitis which were included in this study, 6 dogs (15%) were found to have Malassezia infection, 12 dogs (30%) were found to have flea infestation and 4 dogs (10%) were found to have together.In light of the results that were found in this study, Malassezia and flea infestation hold an important place for dogs which were brought with complaints of dermatitis to veterinary clinics for examination in Ankara and Kırıkkale provinces. Clinical veterinarians must keep in mind that, there is high incidence rates of these 2 dermatitis causing agents and also remember to especially consider them in the list of differential diagnosis.
