VACCINIA virus is now regarded as " pantropic"; Murti and Shrivastav (1957), in their studies on the behaviour of variola virus and one strain of vaccinia virus, observed that the infection became generalized after inoculation on the skin of the rabbit with vaccinia virus, and that lesions of varying severity were seen in the lungs, heart, liver, and kidney, as well as the skin. It is only to b...

Lumpy skin disease (LSD, knopvelsiekte) is a pox disease of cattle characterised by fever, nodules on the skin, mucous membranes and internal organs, emaciation, enlarged lymph nodes, oedema of the skin, and sometimes death. The disease is of economic importance as it can cause a temporary reduction in milk production, temporary or permanent sterility in bulls, damage to hides and death due to ...

ABSTRACT The spatial pattern of Sharka disease, caused by Plum pox virus (PPV) strain M, was investigated in 18 peach plots located in two areas of southern France. PPV infections were monitored visually for each individual tree during one to three consecutive years. Point pattern and correlation-type approaches were undertaken using the binary data directly or after parsing them in contiguous ...

On 7th January 1967, at the Point of Air, Flintshire, I found a Dunlin Calidris alpina which could fly only for short distances before landing awkwardly and running with difficulty. It was easy to catch and proved to have a large tumour-like growth around the tibiotarso-tarsometatarsal joint of the right leg (plate 8a, left). It died shortly after. Dissection showed no obvious internal disease,...

to detect the presence of infectious bronchitis virus (ibv) in infected allantoic fluid (af) of spf embryonated eggs rapid hemagglutination (ha) activity after treatment with neuraminidase enzyme was used. twenty ibv suspected materials were inoculated in spf embryonated eggs via chorioallantoic cavity. harvested afs were treated with neuraminidase enzyme and the presence of ibv was detected by...

Public health surveillance systems are important for tracking disease dynamics. In recent years, social and real-time digital data sources have provided new means of studying disease transmission. Such affordable and accessible data have the potential to offer new insights into disease epidemiology at national and international scales. We used the extensive information repository Google Trends ...

1. Intracerebral inoculation of fowl pox virus in young chicks produces a disease characterized by the development of drowsiness and somnolence 4 to 5 days after inoculation. This is followed by spastic paralysis and convulsions on the 6th and 7th day. The majority of inoculated chicks die on the 7th or 8th day. 2. The pathological lesions are found chiefly in the meninges, perivascular structu...

BACKGROUND Variola virus (family Poxviridae, genus Orthopoxvirus) and the closely related cowpox, vaccinia, and monkeypox viruses can infect humans. Efforts are mounting to replenish the smallpox vaccine stocks, optimize diagnostic methods for poxviruses, and develop new antivirals against smallpox, because it is feared that variola virus might be used as a weapon of bioterrorism. METHODS We ...
