H5N1 Confirmed: Claims thousands of birds/poultry in Tripura

Mysterious disease claims thousands of birds in Tripura



Agartala, April 2: About 3,000 birds, including poultry fowl, have died due to some mysterious disease during the past one week in Tripura, officials said here Wednesday.

Villagers said more than 3,000 chickens, ducks, crows and other birds have first fallen sick and then died at bordering Kamalpur, 160 km north of here.

A team of doctors of animal resource development department (ARDD), led by its deputy director Chandan Kumar Roy, has rushed to the area and started collecting blood samples of the birds.

"Several dogs and five jackals, which had consumed the affected birds, were also found dead," the villagers said.

"We don't think the birds have died of bird flu. We suspect it to be Ranikhet disease. However, we would send the blood sample to national laboratories for confirmation," said Ashim Burman, director ARDD.

Ranikhet is a highly infectious and fatal viral disease, which attacks poultry of all ages. It is also known as newcastle disease.

Earlier, the detection of the H5N1 virus in chickens at the small poultry farms in Moulabibazar district of Bangladesh, opposite to Kamalpur, had prompted the Tripura government to take measures, including sealing of borders, to stop the movement of poultry and poultry products between the two countries.

"We have asked the BSF to maintain a strict vigil along the Indo-Bangla border to prevent illegal trade of poultry and poultry products from Bangladesh," Burman said.

The state forest department has also asked its officials to keep a watch on Tripura's 10 big water bodies where migratory birds from India and abroad are currently breeding.

Newcastle Disease Fact Sheet -

http://www2.dpi.qld.gov.au/health/3950.html

Overview

<table border="1" cellpadding="1" cellspacing="1" width="100%"><tbody><tr> <td width="25%"> Symptoms

</td> <td width="75%"> Some strains of the disease cause only minor symptoms while others are fatal. The severity of the symptoms depends on the strain of the virus and the age and health of the bird. The incubation period is usually 5?6 days but may vary from 2 to 15 days. The ND virus produces four broad clinical syndromes:
Viscerotropic velogenic ND. Appears suddenly and spreads rapidly. Symptoms are marked depression, loss of appetite, sharp drop in egg production, increased respiration, swollen heads, blue combs, and, often, a profuse green diarrhoea that leads to dehydration and collapse. Birds may die within 2 days. Birds that survive the initial phase often develop nervous signs such as twisted necks and muscle twitching. Up to 90% of birds may die.
Neurotropic velogenic ND. Severe respiratory and nervous signs predominate, including coughing and gasping, head tremors, wing and leg paralysis and twisted necks. Depression, loss of appetite and a drop in egg production also occur. Between 10% and 20% of adults and a larger proportion of younger birds may die.
Mesogenic ND. Mainly respiratory signs, with coughing but no gasping. Other signs include depression, loss of weight and decrease in egg quality and production for up to 3 weeks. Nervous signs may develop late in the course of the disease and death rates are about 10%.
Lentogenic ND. Symptoms are mild or absent and include mild respiratory signs, impaired appetite and a drop in egg production.No nervous signs occur and deaths are usually negligible.

</td></tr> <tr> <td> Susceptible species

</td> <td>All birds, both domestic and wild. Most susceptible are domestic chickens, turkeys, pigeons and parrots. Milder disease is seen in ducks, geese, pheasant, quails, guinea fowls and canaries.</td></tr> <tr> <td> Infection and spread

</td> <td>Easily spreads by contact with infected or diseased birds. The virus is excreted in manure and is expired into the air. Other sources of infection are contaminated equipment, carcasses, water, food and clothing.</td></tr> <tr> <td> Distribution

</td> <td>Present in most countries. Severe form of the disease occurred in Australia in the 1930s and in 1998, 1999 and 2002.</td></tr> <tr> <td> Persistence

</td> <td>The virus is readily destroyed by heat, soaps and detergants, hypochlorites, alkalis, gluteraldehyde or Virkon?. The virus is destroyed by direct sunlight within 30 minutes, but in cool weather can continue to survive in manure and contaminated poultry sheds for many weeks. A minimum core temperature of 80?C for one minute destroys the virus in meat products.</td></tr> <tr> <td> Significance

</td> <td>The virus is a serious economic threat to the poultry industry.</td></tr> <tr> <td> Human health

</td> <td>No public health risk to consumers of eggs or poultry products. Mild conjunctivitis and flu-like symptoms have been reported in people working closely with infected birds.</td></tr> <tr> <td> Control

</td> <td>From 1 April 2005, vaccination of chickens in commercial flocks is compulsory under part 8A of the Stock Regulation 1988 .</td></tr> <tr> <td> Other diseases with similar symptoms include:

</td> <td>Avian influenza
Infectious laryngotracheitis (ILT)
Infectious bronchitis
Marek?s disease
Pasteurellosis (cholera)</td></tr></tbody></table>

Tripura (a state of India) is almost completely surrounded by Bangladesh.

Re: Mysterious disease claims thousands of birds in Tripura

And its not Newcastle Disease.

Since H5NQ has been reported in the area, and this outbreak of avian disease seems to have killed dogs and jackals, maybe so.

Unless NDV has also crossed species barriers.

I would be not at all surprised to learn of the latter.

3000 birds die of unknown disease in Tripura


AGARTALA, APR 2 (PTI)

More than 3000 birds including poultry have died of an unidentified desease in the past two weeks in two border villages in West Tripura and Dhalai districts, sources in Animal Husbandry Department said today.

The birds including chicken, duck and crow have died in Mohanpur in West Tripura district and Kamalpur in Dhalai district, sources said adding after infection their heads swelled and started oozing fluid.

A team of doctors of Animal Resource Department rushed to the villages but could not identify the desease. However, they do not suspect the desease to be bird flu.

Villagers told the visiting doctors that a few jackals, a cat and a few dogs have died after eating the dead birds.

Sourses said, doctors suspected that the disese might be ranikhet. Samples are being tested in laboratories here.

Tripura has borders with at least five district of Bangladesh affected by HPAI H5N1 epizootics.

What does it do to cats, dogs, and jackals? H5N1 kills them.
