We expressed a catalytically active cysteine protease, Ac-CP-2, from the blood-feeding stage of the canine hookworm Ancylostoma caninum and vaccinated dogs with the purified protease. Dogs acquired high-titer, antigen-specific antibody responses, and adult hookworms recovered from the intestines of vaccinated dogs were significantly smaller than hookworms from control dogs. There was also a mar...

BACKGROUND Feline calicivirus (FCV) is a common virus, found worldwide, mainly responsible for chronic ulceroproliferative faucitis and periodontitis. This virus has a high mutation rate, leading to the presence of numerous FCV strains in the field. The objectives of this study was to evaluate and compare the efficacy of two vaccines (Leucofeligen™ FeLV/RCP and Purevax™ RCP FeLV), which differ ...

conclusions: in this study, a higher rate of more severe itp in recently vaccinated young children was observed in comparison with other probable etiologies. further investigations are needed to explain this finding. results: 51 patients were enrolled in this study (mean age = 3.86 ± 1.53 months; males = 32 [62.7%]). in 33 (64.7%) patients the platelets level was below 20000 /mm3. thrombocytope...

zataria multiflora essential oil possesses immunomodulatory effects and the present study investigatesits effect on immune responses to live newcastle disease (nd) vaccines and faecal shedding period ofvaccine strain virus in chickens. one hundred and eighty chickens from both sexes were divided into 6 equalgroups: group 1: unvaccinated, group 2: vaccinated (b1 vaccine followed by la sota 10 da...

OBJECTIVE To determine the seroprevalence of antibodies to hepatitis B virus (HBV) and hepatitis A virus (HAV) among children in Jeddah, Kingdom of Saudi Arabia (KSA) and to evaluate the need of anti-HAV mass vaccination. METHODS This study was carried out on random samples of schools located at different regions in Jeddah, KSA during the year 2004. A total of 527 sera, (285 males and 242 fem...

Study Design: A Retrospective/ Comparative Place Duration: was conducted Medicine department Fauji Foundation Hospital Rawalpindi, duration six months from October 2020 March 2021. Methods: Total 120 patients both genders had coronavirus disease were presented study. Patient...

BACKGROUND The objective of the present study was to elucidate the humoral and cellular immune response mechanisms by which a reformulated inactivated chimeric PCV1-2 vaccine reduces the PCV2 viremia. Forty PCV2 seronegative 3-week-old pigs were randomly divided into the following four groups: vaccinated challenged (T01), vaccinated non-challenged (T02), non-vaccinated challenged (T03), and non...

Determination of the vaccination’s effect on immune responses with emergence Sars-Cov-2 pandemic become an important issue. This study aimed to evaluate response anti-nucleocapsid IgG (anti-N IgG) index in naïve, vaccinated, or infected cases, addition suggesting ‘How distinguish between vaccinated versus cases via anti-N IgG?’. Anti-N levels naïve [0.03 (0.02–0.06)], [0.7 (0.2–1.96)], and [3.0...
