Jakarta, on Sunday — the bird flu diagnosis to the poultry increasingly was difficult to be carried out because his clinical sign resembled several other endemic illnesses. So, the breeders and the community must generally increase his vigilance because the poultry that was infected by this bird flu continued to be able to become the source of the spread to humankind. According to the Dean of the School Of Veterinary Medicine of Institut Pertanian Bogor (IPB) I Wayan Teguh Wibawan, on Sunday (11/ 1), when being contacted from Jakarta, the nonexistence of the clinical sign that was typical to the poultry that was infected by bird flu showed the illness was endemic. "This happened not only to the nonpedigreed chicken, but also to the thoroughbred chicken," he said.
"However, that not meant to the change" in the "characteristics" of the "virus happen." Because results of the research showed the virus to the poultry that was given the vaccine stayed cruel, there was this possibility of happening because of the bird flu virus that attacked not 100 percent agreed with antibodies to the chicken, including antibodies that was formed by the vaccine, said Wibawan added. For example, till at this time the group of the bird flu virus from Purwakarta and Sukabumi was different from all the available vaccines in Indonesia. [*See 2 Posts Below this article] That because antigenisitas this virus group was different from two other virus groups in Indonesia, that is the classic Legok group and the South Sulawesi virus group. The manifestation of the illness was sub-clinical showed, it was warned bird flu viruses could be detected and isolated from chickens that appeared healthy. The chicken that was seen healthy then could contain the bird flu virus. "That must be paid attention to because his virus was raging and could be the source" of the "spread," said Wibawan
"Therefore, the bird flu vaccination necessarily only as accessories from the bird flu precaution to the poultry." That more must be paid attention to was sanitation or biosecurity, among them the official must bathe with soap as well as changed clothes and sandals before entering the pen, the handling a camp as the pen foundation, he said.

The Immune virus the Vaccine was found
Rabu, 30/04/2008
The Directorate General (the Director General) Departemen Livestock Breeding of Agriculture found the existence of the virus of H5N1 strain Purwakarta (PWT) immune the bird flu vaccine.

According to Musny, since 2003 till 2006, this virus experienced antigenic drift, so as not vulnerable if vaccinated by using the normal poultry vaccination.
"From 2003 to 2006, this virus experienced antigenic drift, around 27% his amino acid changed so as not vulnerable if vaccinated by using the normal poultry vaccination was used in Indonesia," said Musny to the reporter ended to the speaker in "Insentifikasi Controlling discussions of Bird Flu" that was spread out by the Service of Peternakan West Java yesterday afternoon.
Musny said, uptil now the poultry vaccination that was given to press the spreading of the bird flu virus was the vaccine kind H5N1, H5N2, and H5N9.
Outside strain PWT, said Musny, his side guaranteed the vaccination that circulated to protect the poultry from the bird flu attack was still effective was used for three strain big H5N1 other that is Papua, Sukabumi, and Bali.
With the discovery of the virus of this H5N1 PWT, Musny ordered so that the Service of Peternakan West Java did bio security tightly for all poultry livestock breeding in the region that had strain PWT. Diperkirakan, said he, the number of poultry populations in the region that had strain PWT reached 50 million tails and most were maintained in big livestock breedings.
"Bio security against the poultry at this time must be tighter so that always disinfektan from equipment, vehicle food and his humankind.
His humankind also if entering the location of the pen must with bathed and shampoo hair.
Next month we will also test all strain certain and from the expert's commission broke that would we the test with strain from Sukabumi, X said Musny.
He added, for the program of the poultry vaccination in Indonesia during 2008, has been prepared by 175 million doses of the vaccine H5N1.
65 million doses including being the contribution from the World Bank.
This number, said Musny, still a little compared with the number of targets of the poultry vaccination in sector four in the high risk territory that reached approximately 200 million from around 400 million poultries in sector four.
In the meantime, Peternakan West Java Rachmat Setiadi Section Head said, at this time the step bio security and surveillance continued to be carried out to prevent infected him bird flu in West Java, especially in the territory strain PWT.
Moreover, continued Rachmat, communication with the big breeders also continued to be carried out so that they are careful because of the vaccine that circulated in Indonesia evidently not vulnerable.
