Chinese Streptococcus Suis II Outbreak

Hi,

As this is one site on the usenet that deals with agricultural issues,
I feel it is important that clarification of current animal health
issues is important, even though this might seem irrelevant to some who
are not being directly impacted by this particular swine disease
situation.

Therefore, for the sake of disseminating relevant information to
newsgroups, affiliated with this UKBA site, clarification of the
progress of fighting this disease outbreak in China is warranted.

Yesterday, (3 August, 2005) I personally researched the WHO, FAO and
OIE sites, regarding this situation which has rapidly developed in
China in the past three weeks.

There was no reference made to this outbreak by these world-wide
disease authorities, on their websites, as of yesterday.

Maybe, the comments I posted to this site, yesterday, has caused the
"machinery" to begin to creak back into gear....maybe not.
But, overnight, something has begun to change.

This is more serious than it appears to be. However, the unspoken
reality is that international scientists, vaccine developers on several
continents, were messing around with some Swine DNA and Vaccine
Development ideas since 1998, relative to this particular disease.
That has NOT, been made clear, relative to the present Chinese
situation. Another thing that is not generally spoken in Public about,
is the fact that vendors for materials used to do this research,
promote the research to achieve sales of their products, purchased by
research facilities.

Lelystad (Netherlands) scientists, and microbiologists were working
with Streptococcus Suis II, using immunohistochemistry and DNA research
to identify and modify the gene sequences of this particular
disease...(1999-present). The University of Saskatchewan was also
working on the development of a "combi-vac" vaccine since 2002...a
vaccine that would also combat diseases like PMWS - PRRS - and other
swine diseases in Canadian herds...a "one-shot" intra-nasal vaccine to
immunize pigs with one dose administration. Several other research
facilities have been doing research on Streptoccus Suis II throughout
the period of 2000-2005.

Perhaps Usenet is more beneficial to the Public than we realize.

WHO (the World Health Organization) is beginning to
respond....overnight.

Best Regards to you all -

Burkie

Outbreak associated with _Streptococcus suis_ in pigs in China
-----------------------------------------------
To date, the Ministry of Health in China has reported 206 cases of
human disease associated with an outbreak of _Streptococcus suis_ in
pigs. Of these human cases, 38 have been fatal. As reported by China,
18 patients are critically ill.

Virtually all cases have occurred in Sichuan Province, where
infections with _S. suis_ have been detected in pigs in a concurrent
outbreak. The province has one of the largest pig populations in
China.

Investigation and containment of the outbreak have been given high
priority by Chinese authorities. The country's ministries of health
and agriculture are working in close collaboration, and WHO and FAO
are being promptly informed of new developments.

Investigations conducted by Chinese epidemiologists indicate that the
1st human cases occurred at the end of June 2005 in Ziyang City,
Sichuan Province. From 24 Jun through 21 Jul 2005, the authorities
reported 20 cases of illness of unknown cause admitted to 3 hospitals
in that city. WHO was officially informed of the outbreak on 22 Jul
2005, at which time, 20 cases and 9 deaths had been reported.

Cases have since been reported in 11 prefectures in Sichuan Province.
Most cases reported have occurred in adult male farmers. Information
reported to WHO suggests that close contact with diseased or dead
pigs is the principal source of human infection.

Symptoms reported by local clinicians include high fever, malaise,
nausea, and vomiting, followed by meningitis, subcutaneous
hemorrhage, toxic shock, and coma in severe cases. The incubation
period is short, and disease progression is rapid.

Local experts are conducing active searches for further cases. To
date, Chinese authorities say they have found no evidence of
human-to-human transmission.

The outbreak in humans has some unusual features and is being closely
followed by WHO. Diagnostic testing to further characterize the
causative agent is recommended as an essential part of ongoing
efforts to understand this outbreak, ensure its rapid containment,
and prevent further deaths.
