Has news of this pig disease put you off eating pork?

Pig disease 'Streptococcus suis'

Streptococcus suis, a bacterium which can cause disease in pigs, is found in most countries where pigs are reared. Pigs carry it in their tonsils, and pass it between them either by nose-to-nose or contact or by aerosol if they are close to each other. It is rare for humans to catch it and when they do catch it the results may be severe, involving deafness, endocarditis (inflammation of the lining of the heart), meningitis (inflammation of the membranes that surround the brain or spinal cord) and / or septicaemia (disease of the blood). People handling pigs or pig products with cuts and abrasions are the most likely to catch it. The incubation period is short.

The outbreak of the disease first reported in Sichuan, South West China in July 2005 is unusual for the number of humans infected, for the human death rate, and for the speed with which victims died after first showing symptoms. The first human case is believed to have happened at the end of June in Ziyang City. The disease has spread to Hong Kong. No evidence of human-to-human transmission has been reported, with most cases being male pig farmers. Streptococcus suis is usually treated with penicillin. The fact that so many have died has given rise to concern that the bacterium may have become resistant to one or more antibiotics as a result of their misuse or overuse. Humans are known to have been prescribed antibiotics for colds and flu in Hong Kong, for example, even though they are no use against viruses.

The unusual features of the outbreak have also led to speculation that this might be a different disease such as bird flu, or that it might be a new mutation of the pig disease. The World Health Organization has taken a keen interest in the situation and has urged comprehensive testing and reporting.

Pig disease throws spotlight on use of antibiotics

The high death toll and spread of a pig-borne disease in Sichuan province in southwest China may be due to indiscriminate use of antibiotics in much of Asia, including Hong Kong, enabling bacteria to acquire resistance. 39 have died out of 214 people infected. Antibiotics are of no use against viruses. Resistance is now building up faster than it takes to develop a drug.

Other stories

Experts Discuss Possible Bird Flu Spread

Experts believe that when bird flu reaches Western Europe, authorities will be able to stamp it out before it spreads to humans, as it would be detected quickly in birds or humans, and poultry can be kept inside out of harm's way. It will not be so easy in Southeast Asia, however, as people tend to live much closer to animals. Professional and volunteer bird watchers are collecting samples for scientific analysis in the Netherlands, which will keep its poultry indoors as a precaution.

Vietnam's mass bird vaccination to end in November

Vietnam is in the middle of a mass vaccination of poultry against bird flu and expects to finish by the end of November.

Mass bird deaths found in European Russian region

A large number of bird deaths on a farm in the Caspian region of Kalmykia west of the Ural Mountains, Russia, are being investigated. They may not be due to the bird flu that is concerning scientists, but there has been a cull as a precaution. Over 120 ducks have also died in the Sverdlovsk region, near other regions which have been hit by bird flu. The U.S. State Department is stockpiling Tamiflu for its employees and their families at its embassies in Southeast Asia.

Bush Reads About Salt, Flu While in Texas

President Bush has some serious holiday reading to do. He will be studying the 1918 flu epidemic, and how the U.S. failed to prepare for it (very relevant in view of the lack of preparation for a possible bird flu epidemic that birds just now starting out on their migrations may bring with them). He will also be reading about salt and about Tsar Alexander II.

Pacific Coast Ecosystems Return to Normal

Northerly winds have returned to cool the Pacific Coast, but not soon enough for some wildlife that could not survive in the unseasonably warm waters. The winds are needed to blow the warm water away so that cooler, nutrient rich water can rise and feed the plankton upon which everything else feeds directly or indirectly. The failure of the winds led to many more dead birds than usual and far fewer young fish. As atmospheric systems are so complex, it is hard to be sure whether the failure of the spring winds was due to global warming.

Red Tide Bloom Strikes Off Florida Coast

A major red tide algal bloom has killed life at the bottom of the Gulf of Mexico in an area about 10 miles off the coast of Florida.

Signs of Global Warming?

Animals have reached the Artic that were never there before, and others are headed north. Even salmon have headed into waters that were previously too cold for them. Birds are breeding in new countries, or overwintering where they were previously only summer visitors. Phenologists are noticing plants blooming earlier in the spring. These changes would appear to be due to global warming. Not all species adapt so easily, however - particularly if their food does not.

Doomsday: Are You Ready?

Parts of the USA and Europe have been experiencing very hot weather of late, and we need to adapt. Places that were comfortable to live in the past have become fatal to the unprepared - 40,000 died in Europe in the summer of 2003. There are precautions that we can take to deal with heat and unaccustomed diseases. Animals may die out, or take shelter in places where we are not used to seeing them.

Group Wants to Transplant African Animals, Elephants, lions to roam North America once more?

A group of prominent ecologists wants to populate the Great Plains of North America with lions and elephants. Many scientists and conservationists are against it, having learnt from experienced that introduced species can become invasive and upset the balance of nature, and perhaps kill off some currently-endangered species. It might also adversely affect Africa's tourism industry, but help America's. The supporters want to save African species and restore the biodiversity in North America. Though the African species never lived in North America, similar species such as mastodons, camels and sabre-toothed cats did. The landscape changed markedly after they died out.

A nature park for Koreas' DMZ?

If North and South Korea reunite, Ted Turner wants the Demilitarized Zone between them to become a nature park. It is 248 km (154 miles) long and 4 km (2.5 miles) wide, includes a wide variety of habitats and has been left untouched for over 50 years, to the benefit of some rare species. As well as many rare species of animals and plants, there are many land mines.

Dinosaur-era tree set for first auction sale

Saplings from the Wollemi pine, an Australian tree that was eaten by dinosaurs and that has only recently been discovered, are to go on sale. The tree, which had only been known as a fossil, can live for 1,000 years and grow to at least 40 meters tall, so it is a major long-term investment.

Sacred Sri Lanka tree out of the woods in Taiwan

A sapling from the Jaya Siri Maha Bodhi, a tree believed to be descended from the tree under which the Buddha sat and attained enlightenment, was sent to Taiwan's Ling Jiou Mountain Buddhist Society by the Sri Lankan government. Customs rejected it last month for fear that it had parasites. It was sent to Hong Kong for specialist treatment, and has now been allowed into Taiwan.

Most Americans have allergies

54.3 percent of Americans has at least one allergy, particularly for dust mite, rye, ragweed, and cockroach, but also for Bermuda grass, cat, Russian thistle, white oak and mould. About 8.9 percent were allergic to peanuts.

Product Recall: Sun-Dried Tomatoes

Casale Sun-Dried Tomatoes 2003 crop, sold by Utica, N.Y.-based Atlantic International Products Inc. have been recalled because there is an unlisted ingredient, sulphites, capable of producing severe reactions in asthmatics.

Eating fruits and vegetables may cut arthritis risk

Some carotenoids commonly found in some fruits and vegetables and orange juice appear to help stave off arthritis. The carotenoids give the fruit and vegetables their red or yellow colouring.

Secondhand smoke costs nearly $10 bln in U.S.-study

The Society of Actuaries reports that the cost to the U.S. of second-hand smoking is nearly $10b p.a., about half from the cost of treatment of lung and heart ailments, and half from loss of productivity and costs due to disability.

Study: Car Exhaust Polluting Puget Sound

A study of the marine sediments at the bottom of Puget Sound shows that pollution due to heavy industry (toxic metals) is declining while pollution from vehicle exhausts (polycyclic aromatic hydrocarbons) is increasing.

Vietnam to bug bears to stop wildlife smuggling

Vietnam is to microchip around 4,000 captive bears. They hope this will deter wildlife traders from catching more wild bears and selling them to bile farms or killing them foor food.

3 Researchers Rescued From Arctic Island

Three shipwrecked, unarmed Polish researchers were rescued by helicopter from a remote Arctic island as polar bears were closing in.

Mozambique village draws divers, counts cost

Mozambique's Ponta d'Ouro has warm waters, beautiful corals and unspoiled beaches, drawing in tourists, who bring work, albeit unskilled and poorly paid. The commercialisation is threatening the environment, however, and changing the nature of the village and bringing corruption.

Spanish surfers' paradise loses its wave

Conservation is never easy, balancing the requirements of different animals, groups of people, and economies. Then there is the debate about which condition to restore an area to, plus scientific uncertainty.

The tiny Basque village of Mundaka was invaded by surfers each year because of its world championship class surf, yet managed to remain relatively unspoilt. Now the wave has vanished, and there are differences of opinion as to why. Some say it was because the estuary was dredged more deeply than usual in 2003 for a newly built ship. Others say it is because there have been fewer big storms in the Atlantic Ocean in recent years. Others say it was because the dredged sand was used to restore a sand dune for the benefit of wildlife. The area is a UNESCO Biosphere Reserve. The surfers say that the wave is natural and is part of what should be protected, and that rebuilding the dune was meddling with nature. The government has ordered an investigation, as the surfing was important to the local economy.

19 Soldiers Struck by Lightning in Ga.

19 soldiers at Fort Benning were struck by lightning and hospitalized, in spite of taking precautions.

BP Receives Urgent Safety Recommendation

The U.S. Chemical Safety and Hazard Investigation Board has for the first time issued an urgent safety recommendation. The target is BP PLC, whom it wants to form an independent panel of experts to review safety. BP has five North American oil refineries, in California, Indiana, Ohio, Texas and Washington. This was triggered by recent accidents at the company's Texas City refinery.

Iraq Enjoys Some of World's Cheapest Gas

Iraq is massively subsidising gas at the pump, and would find it difficult to reduce the subsidies in the light of insurgency and other woes (other countries also have problems lifting subsidies). At the other extreme, some other countries levy a hefty tax. Some prices per gallon include: Iraq 5 cents, Iran 38 cents, Jordan $1.89, Syria $1.74, USA $2.55, UK $6.24. The IMF believes that the cost of subsidies is harming Iraq's economy, along with the lower production of oil due to violence, and that the government will run short of money before the end of the year. Iraq has proven oil reserves of about 115 billion barrels, with much of the country still to be explored.
