Brazil: Thousands of Flesh-Eating Piranhas Infest Beach, Bite Swimmers

11/17/2011 Leave a comment

“Thousands of flesh-eating piranhas have infested a beach popular with tourists in western Brazil and have bitten at least 15 unwary swimmers.

Officials in the city of Caceres in Mato Grosso state say this is the first time they have had a problem with piranhas at the Daveron beach on the Paraguay river, where the aggressive fish began schooling about two weeks ago.

‘People have got to be very careful. If they’re bitten, they’ve got to get out of the water rapidly and not allow the blood to spread,’ firefighter Raul Castro de Oliveira told Globo TV’s G1 website yesterday.

Elson de Campos Pinto, 22, was bitten on Sunday.

‘I took a dip in the river and when I stood up, I felt pain in my foot,’ Pinto told G1.

‘I saw that I had lost the tip of my toe. I took off running out of the river, afraid that I would be further attacked because of the blood. I’m not going back in for a long time.’

City officials said the beach will remain open because it’s an important draw for tourists in Brazil’s Pantanal region, known for its ecotourism…

‘Everyone knows there are piranhas in the region and have always taken the necessary precautions,’ he said.

‘What is different this time is that they’ve appeared where they never appeared before.'” Read more.

Australia: Mystery Disease Killing An ‘Unprecedented Number’ of Fish and Other Marine Life in Gladstone Waters

11/09/2011 Leave a comment

“An unprecedented number of fish with red spots, lesions and parasites, as well as dead dugongs and turtles, have been found this year.

Fishermen and conservationists blame the state of the marine life on dredging to widen Gladstone Harbour to accommodate carrier ships servicing the booming liquefied natural gas and coal seam gas industries.

But the Gladstone Port Corporation does not believe the dredging is causing the disease in fish, and authorities say last year’s wet summer may be a factor in the poor health of the harbour.

Water testing shows a number of sites within the harbour exceeded national guidelines for aluminium, copper and chromium. Experts say the levels pose a minimal risk to marine life; however, the Queensland Government has appointed an independent scientific panel to conduct more research.

Far North’s green sea turtles too hungry to breed – “Seagrass meadows from Mission Beach south to Townsville were devastated by cyclone Yasi in February and in the following months, reports of dead and sick turtles were highlighted right up the coast. Nine months after the monster storm, traditional turtle spots such as Cowley Beach are without nests and Mark Hamann from James Cook University’s School of Earth and Environmental Sciences said it was because the species failed to fatten up before the breeding season – leaving many with no extra energy for mating. ‘The turtles we are seeing are not in the best condition,’ he said. ‘Their shells have sunken in and in the lead-up to breeding season they would have been very hungry, so I will not be surprised if many traditional nesting spots don’t turn up any turtles this year.'” Read more.

 

Cantaloupe Listeria Becomes Deadliest Ever Food Outbreak as Death Toll Reaches 29

11/04/2011 Leave a comment

“The death toll from the listeria outbreak that’s been traced back to Colorado cantaloupes has now climbed to 29, making it the deadliest food-bourne illness outbreak ever recorded in the United States.

The Centers for Disease Control and Prevention (CDC) reported the increase in the total number of deaths earlier this week, and noted that the number of people infected has gone up to 139 in 28 states.

On Wednesday night, a CDC official confirmed that this latest food-borne illness outbreak was the deadliest on record, surpassing the one linked to listeria-tainted cheese that killed 28 people in Mexico in 1985.

‘There were 28 deaths (adults as well as infants) and 20 miscarriages and still-borns from Jalisco,’ the official said in an email.

‘No other outbreak in recent times, since we began collecting/recording data in 1973 comes close. Of course the system for collecting and tracking food-bourne disease is much more precise now.’

The outbreak began in August and stemmed from Rocky Ford-brand cantaloupes sold by Jensen Farms near Holly, Colorado.

The cantaloupes were recalled Sept. 14, and no melons under the recall are still on store shelves.” Read more.

New York: Swarms Of Blood-Thirsty Underground Insects Invading, Terrorizing New York City Homeowners

11/04/2011 Leave a comment

“NEW YORK (CBS 2) — An insect invasion is terrorizing New York City homeowners, making life miserable, even dangerous, for many families. Parents have been forced to take extreme measures to protect their children and their homes.

CBS 2’s Dave Carlin investigates the growing Upper West Side mosquito mystery.

These rare mosquitoes are extra blood-thirsty and active year-round. Carlin saw some of them in a lab after they were collected in the unlikeliest of places, Bernard Lagan’s home on West 84th Street.

‘They trapped 150 mosquitoes in the basement in a 24-hour period coming from underground and into the basement and up in to the house through the air vents and it’s the same story as the other brownstones on this block,’ Lagan told Carlin.

It’s an invasion that has almost every resident of 84th Street between Riverside and West End Avenue slapping, scratching and suffering.

‘They’re hungry. They’re hungry,’ said resident Susan Nicholson.

‘Three on this ear; one on his cheek; one on his neck,’ another woman said, illustrating the bites on one of her children. ‘And there are some on his arms going up his arm.’

Frustrated neighbors said after numerous complaints to the city and no concrete action, they feel abandoned. So like busy bees, they’re taking matters in to their own hands: covering cracks, vents and drains, both inside and out.” Read more.

Texas: Red Tide Kills Another 1.2 Million Fish Along Coast in Less Than Two Weeks

11/04/2011 Leave a comment

“AUSTIN, Texas (AP)  The algae bloom known as red tide has killed 1.2 million more fish along the Texas coast in less than two weeks.

The Texas Parks and Wildlife Department reported Monday that about 4.2 million fish have died since the red tide outbreak began in September. The agency on Oct. 20 estimated 3 million fish had been killed.

State health officials last week banned, until further notice, commercial and recreational harvesting of oysters, clams and mussels due to red tide. Tuesday would have been opening day for public harvest of oysters through April.

Experts say red tide, often present in the fall, is worse this year because of the Texas drought and recent excessive heat. The algae thrive in warm, salty water.

Red tide can cause respiratory problems in people.” Source – WTAW NewsTalk.

UK: Britain on Alert for Strain of Killer Flu, ‘One of the Biggest Biological Threats of Our Time’

11/03/2011 2 comments

By Jo Willey – “A NEW strain of killer flu which could spread to ­Britain within 24 hours is ‘one of the biggest biological threats of our time’, experts warned.

The alert comes after people started to fall victim to seasonal flu and the more virulent swine flu at the same time.

Such a rare incidence creates the risk of a lethal mutation, leading to an ‘ominous’ super-flu virus for which humans have almost no immunity, said medical scientists.

Dr Peter Hotez, a world-renowned infectious disease expert, warned: ‘Highly infectious strains of the virus against which humans have little defence can spread from one continent to another within 24 hours.’ He said the fact scientists had detected the rare double-flu infection highlighted the need for extreme vigilance against new killer strains around the world.

Dr Hotez, president of the American Society of Tropical Medicine and Hygiene, praised the scientists who had made the discovery.

But he warned: ‘We are required to remain vigilant against one of the biggest biological threats of our time.’

This comes as Britain’s winter flu season gets underway, amid fears it could be one of the worst outbreaks of the disease in years.

Last year more than 600 people died from winter flu in the UK, with hospitals so overwhelmed they were forced to cancel routine ­operations.

The severity of the outbreak in late 2010 took experts by surprise as it was far more virulent than had been predicted.

But many Britons still have little immunity to the virus strain because of low uptake of the vaccine that fights it.

The true nature of this year’s virus won’t be known until the weather gets colder and people spend more time indoors, which leads to the quick transmission of the disease.” Read more.

India: Outbreak of Deadly Diseases Including ‘Mystery Illness’ Hits Children in Rayalaseema Region

10/28/2011 Leave a comment

“An outbreak of diseases, one of these being described as a mystery illness, has taken a heavy toll on children in Andhra Pradesh’s Rayalaseema region. At least 500 children, aged between two and five, have been admitted to the Kurnool Government General Hospital with symptoms of dengue, chikungunya and ‘strange viral fevers’, doctors say.

Since October 12, the hospital has seen the death of 22 children. Just how many of them died due to viral fever is not clear. Resident medical officer Dr Gopal Raj said the high death count is due to the large number of children admitted to the neo-natal ICU following complications at birth. Kurnool Government Hospital is the largest referral hospital in Rayalaseema, especially for newborns.

The state government ordered an inquiry on Tuesday after being criticised by the National Commission for Protection of Child Rights (NCPCR) the previous day. A team of health department, sanitation and Pollution Control Board officials has been sent to Kurnool and Kadapa districts to assess the situation.” Source – Indian Express.

Mysterious disease kills 28 children in India – “In India’s Bihar state, at least 28 children have died in the past week from an unidentified illness. Officials said that all of the children were between two and eight years. They died in Muzaffarpur town, 80kms (50 miles) from the state capital, Patna. Bihar Health Minister Ashwani Choubey told that a team of doctors from Delhi is visiting Muzaffarpur on Tuesday to diagnose the disease. The children died after reporting high fever followed by bouts of unconsciousness and convulsions.” Read more.

Haiti: Cholera Outbreak Worsens with More Than 6,500 Dead and Hundreds of Thousands Sickened

10/22/2011 Leave a comment

By MARK DUNPHY – “The Haitian government has reported more than 6,500 deaths as a result of the ongoing cholera outbreak in Haiti, health officials said on Saturday. Hundreds of thousands more have been sickened.

According to the United Nations (UN) World Health Organization (WHO), Haiti has recorded nearly 470,000 cases of cholera, including 6,595 deaths, since an epidemic of the disease erupted approximately one year ago.

WHO spokesperson Tarek Jasarevic said the disease could infect another 75,000 people by the end of the year if the current trend continues. Of the nearly 470,000 patients, some 250,000 people have been hospitalized.

If the rate does continue, the number of total victims could reach more than half a million in a country of approximately 9.7 million.

After a decline in weekly cholera cases in August, the number of cases rose again in September. Areas such as the South and Nippes departments, Nord, Centre and the capital of Port-au-Prince all saw significant increases.” Read more.

First Ebola-Like Virus Native to Europe Discovered

10/21/2011 Leave a comment

“A team of international researchers has discovered a new Ebola-like virus – Lloviu virus — in bats from northern Spain. Lloviu virus is the first known filovirus native to Europe, they report in a study published in the journal PLOS Pathogens on Octobr 20th.

The study was a collaboration among scientists at the Center for Infection and Immunity (CII) at Columbia University’s Mailman School of Public Health, the Instituto de Salud Carlos III (ISCIII) in Spain, Roche Life Sciences, Centro de Investigación Príncipe Felipe, Grupo Asturiano para el Estudio y Conservación de los Murciélagos, Consejo Suerior de Investigaciones Científicas and the Complutense University in Spain.

Filoviruses, which include well-known viruses like Ebola and Marburg, are among the deadliest pathogens in humans and non-human primates, and are generally found in East Africa and the Philippines. The findings thus expand the natural geographical distribution of filoviruses.

‘The study is an opportunity to advance the knowledge of filoviruses’ natural cycle,’ said Ana Negredo, one of the first authors of the study.

Scientists at ISCIII analyzed lung, liver, spleen, throat, brain and rectal samples from 34 bats found in caves in Asturias and Cantabria, Spain, following bat die-offs in France, Spain and Portugal in 2002 affecting mainly one bat species.

They screened these samples for a wide range of viruses using the polymerase chain reaction, a molecular technique that allows scientists to amplify genetic material, and. detected a filovirus. Filoviruses include ebolaviruses and marburgviruses, two viruses associated with severe disease in humans and other primates.” Read more.

British Columbia: Red Tide Alert for Waters Around Nanaimo

10/21/2011 Leave a comment

By Jenn McGarrigle – “Fisheries officials closed areas around Nanaimo for shellfish harvesting due to unacceptable marine biotoxin results Wednesday.

Some areas south of Nanaimo are closed to harvesting all bivalve shellfish (oysters, clams, scallops, mussels and geoducks). Other areas in and around Nanaimo are closed to harvest of all bivalve shellfish except manila clams, littleneck clams, oysters and mussels; or are open except for harvesting of butter clams and scallops.

A complete list of the closures, as well as a map of the sub-areas around Nanaimo, is available at http://www.pac.dfo-mpo.gc.ca/psp. This information is also available by calling toll-free 1-866-431-3474.

Red Tide (Paralytic Shellfish Poisoning contamination) is caused by microscopic marine organisms that product toxins that can accumulate in bivalve shellfish because these animals filter feed.

Eating shellfish in a red tide zone can result in serious illness or death.” Read more.

New Zealand: Measles Outbreak Hits Waiheke Island

10/20/2011 Leave a comment

“The measles outbreak which has infected more than 200 Aucklanders has now spread to Waiheke Island.

A 17-year-old resident on the island recently tested positive for the disease, Dawn Rigby, Manager of the Waiheke Trust says.

It is not known where the teenager contracted measles but because of the school holidays his contact with others has been limited.

There are no other suspected cases on Waiheke.

Since the measles outbreak began in May there have been 229 confirmed cases of the disease in Auckland.

Health officials are urging anyone who has not been immunised against the disease to be vaccinated.

The Ministry of Health is working with the three Auckland district health boards to ensure there is a sufficient supply of the measles vaccine, as the disease continues to spread.

Officials will administer the measles, mumps and rubella (MMR) vaccine for anyone who is not immunised free of charge.

The best protection against the disease is to have two doses of the MMR vaccine.

It is vital people born after January 1, 1969 check their immunisation status and if they are not vaccinated or have only received one dose of the vaccination, they should arrange an MMR vaccination.” Read more.

Antibiotics: Killing Off Beneficial Bacteria … for Good?

10/18/2011 Leave a comment

By Maryn McKenna – “It’s an accepted concept by now that taking antibiotics in order to quell an infection disrupts the personal microbiome, the population of microorganisms that we all carry around in our guts, and which vastly outnumbers the cells that make up our bodies. That recognition supports our understanding of Clostridium difficile disease — killing the beneficial bacteria allows C. diff room to surge and produce an overload of toxins — as well as the intense interest in establishing a research program that could demonstrate experimentally whether the vast industry producing probiotic products is doing what it purports to do.

But implicit in that concept is the expectation that, after a while — after a course of antibiotics ends — the gut flora repopulate and their natural balance returns.

What if that expectation were wrong?

In a provocative editorial published this week in Nature, Martin Blaser of New York University’s Langone Medical Center argues that antibiotics’ impact on gut bacteria is permanent — and so serious in its long-term consequences that medicine should consider whether to restrict antibiotic prescribing to pregnant women and young children.

Early evidence from my lab and others hints that, sometimes, our friendly flora never fully recover. These long-term changes to the beneficial bacteria within people’s bodies may even increase our susceptibility to infections and disease. Overuse of antibiotics could be fuelling the dramatic increase in conditions such as obesity, type 1 diabetes, inflammatory bowel disease, allergies and asthma, which have more than doubled in many populations.

Among the findings he cites in support: The population-level observation that the incidence of infection with H. pylori, the bacterial cause of gastric ulcers, has declined over decades just as the incidence of esophageal cancer has risen. In addition, he offers his own research group’s observation that children who don’t acquire H. pylori are at greater risk of developing allergy and asthma, and their findings that eradicating H. pylori affects the production of the two hormones, ghrelin and leptin, that play a role in weight gain.” Read more.
