Turkey arthritis reovirus (TARV) causes lameness and tenosynovitis in commercial turkeys and is often associated with gastrocnemius tendon rupture by the marketing age. This study was undertaken to characterize the biomechanical properties of tendons from reovirus-infected turkeys. One-week-old turkey poults were orally inoculated with O'Neil strain of TARV and observed for up to 16 weeks of ag...

AIM The purpose of this study was focused on the identification of tumor diseases in turkeys on the basis of a detailed description of epidemiological features, clinical signs, lesions, and histopathological changes. MATERIALS AND METHODS Outbreak of a tumor disease in turkeys was investigated in various regions of Eastern Algeria. Four turkeys' flocks aged from 17 weeks were affected, result...

Sentinel ducks and domestic turkey flocks were monitored for influenza infection during a 4-year period. The onset of infection among ducks was similar each year, occurring in late July or early August. Influenza in turkeys was also shown to be seasonal, but the usual onset was 6 to 8 weeks after the detection of influenza in sentinel ducks. Possible explanations for the delayed infection in tu...

To determine susceptibility of chickens, turkeys, and mice to pandemic (H1N1) 2009 virus, we conducted contact exposure and inoculation experiments. We demonstrated that chickens were refractory to infection. However, oculo-oronasally inoculated turkeys and intranasally inoculated mice seroconverted without clinical signs of infection.

The protozoan parasite Histomonas meleagridis is the causative agent of histomonosis in gallinaceous birds. In turkeys, the disease can result in high mortality due to severe inflammation and necrosis in caecum and liver, whereas in chickens the disease is less severe. Recently, experimental vaccination was shown to protect chickens and turkeys against histomonosis but dynamics in the cellular ...

In this paper, we propose a video analytics system to identify the behavior of turkeys. Turkey provides evidence assess turkey welfare, which can be negatively impacted by uncomfortable ambient temperature and various diseases. particular, healthy sick turkeys behave differently in terms duration frequency activities such as eating, drinking, preening, aggressive interactions. Our incorporates ...

An epidemic of Newcastle disease occurred in turkeys of Southern Utah in the late fall of I965. Several workers in intimate contact with the turkeys at the processing plant developed a follicular conjunctivitis subsequently identified as due to Newcastle disease virus. The typical clinical findings and rise in haemagglutinin-inhibition titre indicated that the infection was acquired from the tu...

Sanitary constraints of raising turkey in north-west Benin were studied by using a survey and Haemagglutination Inhibition Test (HIT) to detect antibodies of Newcastle Disease (ND) and Avian Influenza (AI). We tested 85 serums from 7- to 24-month-old turkeys raised in 19 farms. ND prevalence rate was 54% but reactions on four sub-types of AI were negative. Mortality rates varied from 55 to 100%...

Newcastle disease (ND) is a highly contagious infection of many avian species, mainly chickens and turkeys, with a devastating impact on worldwide poultry production. The ND accounts for heavy losses in Iranian poultry flocks. There are some reports regarding the epidemiology of this infection in Iran. This study was performed to investigate the infection of turkeys with a Newcastle disea...

Following experimental inoculation of 3-week-old turkeys with different titres (106, 104, 103, 102 and 101 egg infectious dose (EID50)) of A/ostrich/Italy/984/2000 H7N1 highly pathogenic avian influenza virus (HPAIV), the selected tissues and organs were examined for pathological changes. Tissue samples from different organs that obtained from dead and sacrificed birds were fixed in 10% neutral...
