Virulent Newcastle disease (VND), formerly exotic Newcastle disease, [1] is a contagious viral avian disease affecting many domestic and wild bird species; it is transmissible to humans. [2] Though it can infect humans, most cases are non-symptomatic; rarely it can cause a mild fever and influenza-like symptoms and/or conjunctivitis in humans.
PPMV1 or pigeon paramyxovirus type 1 is a virus closely related to Newcastle disease which affects domestic pigeons and other bird species. It probably originated in the Middle East but has spread to Europe, the USA and Australia, where it has the potential to infect and kill native bird species.
Newcastle is a viral disease that affects domestic and wild birds, causing respiratory problems, among other symptoms, and Brazil detects first Newcastle disease case in poultry since 2006 Skip to ...
Typical symptoms of an infection with the pigeon pox virus. Pigeon pox is a viral disease to which only pigeons are susceptible. It is characterized by pox scabs, which most frequently form on the featherless parts of the bird. The disease is caused by the Pigeon pox virus. It can be transmitted by droplet infection from one animal to another ...

In addition, virus antigen can be detected double immunodiffusion. Postmortem examination may reveal a variety of clinical signs relating directly to the organ affected. Specifically, Egg Drop Syndrome can be diagnosed by hemagglutinin inhibition and the virus causes haemagglutination in chickens and ducks.
Metronidazole is the treatment of choice. Treatment usually is successful after 1–2 days with early diagnosis. A new culture system called InPouch has practical advantages over the usual in vitro system. There is a risk of uncontrolled bleeding if oral plaques are removed by forceps, holding open the beak can also suffocate the bird. [11]
The HSV virus used as an oncolytic virus has retained their native thymidine kinase gene which allows it to be targeted with antiviral therapy in the event of unwarranted side effects. [8] Other challenges include developing an optimal method of delivery either directly to the tumor site or intravenously and allowing for target of multiple ...
