BACKGROUND Tuberculosis (TB) remains a global health problem, with vaccination likely to be a necessary part of a successful control strategy. Results of the first Phase 2b efficacy trial of a candidate vaccine, MVA85A, evaluated in BCG-vaccinated infants were published last year. Although no improvement in efficacy above BCG alone was seen, cryopreserved samples from this trial provide an oppo...

A total of 120 4-week-old broiler chickens were allotted to 12 pens and fed one of three diets including control, oxidized diet (5% oxidized oil), or antioxidant-added diet (500 IU vitamin E) for 2 weeks. Blood samples were collected at the end of feeding trial, and breast muscles were sampled immediately after slaughter. Breast meats were also collected 24 h after slaughter and used for meat q...

We have investigated the effects of ovariectomy (OVX) and photostimulation (PS) on anterior pituitary LH beta mRNA abundance and circulating levels of LH in the domestic turkey. The birds were divided into the following four treatment groups: non-PS SHAM, PS SHAM, non-PS OVX, and PS OVX. Photostimulation was initiated 7 days after OVX. Anterior pituitaries and blood samples were collected on Da...

A study was conducted to evaluate the molecular and cellular immunomodulatory effects of a Saccharomyces cerevisiae fermentation product (Original XPC, Diamond V) in broilers. Our lab has previously demonstrated that broilers fed XPC generate faster and stronger antigen-specific humoral immune responses to Newcastle disease virus (NDV) vaccination. This study aims at investigating the mechanism...

an experiment with 240 one-day-old lohman male broilers was conducted to investigate the effects of different levels of palm kernel meal supplemented diet with/without enzyme on performance and lactic acid bacteria population of ceca. birds were distributed in 20 experimental units and data were analyzed in a complete randomized design with 2x2 arrangement plus a control diet.the levels of palm...

Two oil emuisified vaccines of Newcaslte disease were prepared from Lasota strain. The virus was propagated in 9-day-old chicken embryos through allantoic route. The haemagglutination titre of the allantoic fluid used for vaccine preparation was 2048. The fluid was inactivated by 0.1 per cent f nal concentration of formalin at 37 oc for 6 hours. Inactivated allantoic fluid was emulsified with a...

newcastle disease is one of the most important causes of economic losses in the poultry production and can be resulted in high mortality. antibody detection is also an important tool for assessment of the immunity against the disease. in the present study a trial was conducted to evaluate the effect of an immune stimulator (echinacea purpurea) on antibody production against newcastle disease va...

OBJECTIVE In the U.S., seasonal trivalent influenza virus vaccine (TIV) is currently universally recommended for all pregnant women. However, data on the maternal inflammatory response to vaccination is lacking and would better delineate the safety and clinical utility of immunization. In addition, for research purposes, vaccination has been used as a mild immune trigger to examine in vivo infl...

PURPOSE A prospective, epidemiologic study was conducted to assess whether the 2009 pandemic influenza A(H1N1) vaccination in Germany almost exclusively using an AS03-adjuvanted vaccine (Pandemrix) impacts the risk of Guillain-Barré syndrome (GBS) and its variant Fisher syndrome (FS). METHODS Potential cases of GBS/FS were reported by 351 participating hospitals throughout Germany. The self-c...

Background & Aims: The H9N2 avian influenza subtype is endemic in many parts of Iran and has the ability to transmit from bird to human. In the present study, the risk of this subtype for humans was assessed by determination of the viral titer and shedding time in bird. Method: The experiment was done on fifteen male budgerigars at 4 months of age. The birds w...
