Florida’s Coral Reefs Face Mysterious Disease

Around the world, coral reefs are facing trouble. Coral bleaching, due in part to rising ocean temperatures, has stressed reefs, leaving them weakened and susceptible to disease. Now, in Florida, scientists are struggling to combat a mysterious disease that’s threatening the future of the world’s third largest coral reef.

In just four years, the so-far unidentified disease has already had a dramatic impact on Florida’s reef tract, which extends some 360 miles down the state’s Atlantic coast.

When corals are affected by the disease, the tissue sloughs off the skeleton. Once a coral is infected, it usually kills the entire coral, sometimes within weeks.

It’s proved especially deadly for species of brain and star coral, which form the foundation for many reefs. In some areas now, almost all of those corals are dead.

Scientists believe ocean currents help spread the disease. Since it was first discovered, it’s moved north, affecting reefs all the way up to the St. Lucie inlet. It’s now moving south, through the Florida Keys.

A large number of researchers are working to tackle the disease on many fronts. Some are using DNA analysis to try to identify the pathogens involved. Others are looking for ways to stop the disease from spreading.

Turtle herpes outbreak at Queensland Island, Australia

Two green sea turtles covered in tumours have washed ashore a bay off Magnetic Island in the past two weeks, victims of a crippling disease spreading through turtle populations.

The turtles were likely part of a larger group surveyed earlier this year just off West Point at Cockle Bay, where half of the green turtle population was found to have large tumours around their heads, eyes and shoulders.

Unpublished results have found the tumours are likely caused by fibropapillomatosis, a disease triggered by a turtle-specific herpesvirus that affects sea turtles across the world likely caused by pollution.

The tumours can grow up to 30 centimetres and while they are benign, they can leave turtles susceptible to other causes of death.



Measles Outbreak in Ireland

Forty suspected cases of measles have been reported to the HSE’s Health Protection Surveillance Centre (HPSC), of which 21 have been confirmed.

The outbreak centres on the south-west of the country but some cases have been reported in Dublin, the mid-west and north-east.

Although public health doctors have traced the origin and spread of the disease, the outbreak has not been contained.


Crow Disease Carriers

Large gatherings of crows, which can congregate in flocks of tens of thousands, may be spreading disease to other species, including humans.

University of California, Davis, researchers found that approximately half of the 6,000 American crows that winter around the campus carry Campylobacter jejuni, which is the leading cause of human gastroenteritis in industrialized countries.

GPS tracking found the birds like to gather around areas with easy access to food, such as dairy barns.

The researchers say this could potentially play a role in spreading the disease to domestic animals, and through them, to humans.


Zika virus infection – Netherlands – Sint Maarten

On 25 February 2016, the National IHR Focal Point for the Netherlands notified WHO of two laboratory-confirmed cases of Zika virus infection in the Island of Sint Maarten. Sint Maarten is an independent state within the Kingdom of the Netherlands. It is one of the Leeward Islands situated in the western part of the Caribbean region, east of Puerto Rico.

Rare Elizabethkingia Bacteria Outbreak – Wisconsin, USA

A deadly bacterial outbreak is being investigated in Wisconsin with at least 44 reported cases, killing 18 people, according to the Wisconsin Department of Health Services.

The rare infection results from a naturally occurring bacteria called Elizabethkingia anophelis, which are found in soil, fresh water and reservoirs, health officials said. Symptoms include fever, shortness of breath, chills or redness on the skin.

The outbreak has primarily affected people over the age of 65 and everyone infected had a history of at least one serious underlying health condition. State and federal health officials said they’re looking to find the source of the outbreak.


Meningitis Outbreak in Niger

The government said Friday that since January the epidemic has killed 129 people out of 1,150 cases as of Wednesday. Just three days earlier on Sunday officials reported 85 deaths and 908 cases.

A couple dozen victims had died of the disease by the end of March, but in April the number of infections accelerated into an epidemic.

Several strains of the infection, which can be highly contagious, have been circulating in the landlocked nation of nearly 18 million in west Africa.

Niger, one of the world’s poorest countries, is prone to such epidemics because of its position in the “meningitis belt” that stretches from Senegal in the west to Ethiopia in the east, according to the World Health Organization (WHO).

Meningitis is an inflammation of membranes protecting the spinal cord and the brain, and the first symptoms include stiffness and severe headaches.


Amazon Tribe Reveals Western Life Is Killing Good Germs

Samples of germs taken from a tribe of once-isolated indigenous people in Venezuela’s Amazon region found that the tribesmen’s seclusion from the outside world until recently has allowed them to keep the highest diversity of bodily bacteria ever observed among humans.

The trillions of mainly beneficial bacteria our body uses for digestion and immunity have come under assault over the past 75 years by the use of antibiotics, and they are also diminished by the sanitary conditions people mainly enjoy in modern life.

Writing in the journal Science Advances, researchers say that comparing bacterial DNA from the Amazon’s Yanomami villagers with samples from U.S. residents reveals that microbes are about 40 percent less diverse in the American population.

The findings support the theory that lower microbial diversity now found in the developed world may be linked to immune and metabolic diseases like allergies, asthma and diabetes.

“The challenge is to determine which are the important bacteria whose function we need to be healthy,” said researcher M. Gloria Dominguez-Bellow of New York University.


Zimbabwe Battles New Cattle Disease Outbreak

AN outbreak of lumpy skin cattle disease in Masvingo Province, Zimbabwe is feared to have left 5 000 cattle affected.

The worst affected areas include Gutu , Masvingo, Zaka, Bikita, Mwenezi and Chiredzi.

The Department of Veterinary Services is currently carrying out vaccinations of all cattle in the province amid reports of shortages of vaccines and veterinaries.

The outbreak of the lumpy skin cattle disease coincided with farmers in Chiredzi and Mwenezi battling to contain the foot and mouth disease.

Movement of cattle in Chiredzi, Mwenezi and parts of Bikita has been suspended due to the disease.

All public cattle auctions have also been suspended in areas were the disease has wrecked havoc.

Last year, there were no cattle on show at the Masvingo Agricultural Show following an outbreak of foot and mouth in Mwenezi and Chiredzi Districts.

These are traditionally cattle ranching areas in the country.

Such setbacks have hampered plans to rebuild the national herd, which was decimated by the drought suffered in 1992.

Plant Virus May Be Behind Massive Honeybee Deaths

Chinese and U.S. researchers say a virus that typically infects plants has been found in honeybees.

The scientists inadvertently found tobacco ringspot virus (TRSV) during routine screening of bees.

“The results of our study provide the first evidence that honeybees exposed to virus-contaminated pollen can also be infected and that the infection becomes widespread in their bodies,” said lead author Ji Lian Li, at the Chinese Academy of Agricultural Science in Beijing.

He added that the honeybees can also spread TRSV as they move from flower to flower and between plants.

TRSV is particularly dangerous since it produces a flood of mutations that infect in different ways.

Bee colonies found with high levels of various viral strains were less successful in surviving harsh months last winter than those with lower levels of infections.

One-third of U.S. honeybee colonies died off during the winter of 2012-13, a 42 percent increase in fatalities from the previous winter.

TRSV infections could be at least one factor behind colony collapse disorder, which has stumped scientists for years.



Middle East respiratory syndrome coronavirus (MERS-CoV) – update

On 20 December 2013, WHO has been informed of an additional laboratory-confirmed case of Middle East Respiratory Syndrome coronavirus (MERS-CoV) in United Arab Emirates (UAE).

Malaria outbreak in Dadeldhura, Nepal.

According to Prasotum Gautam, one of the local experts, the open border with India and the continuous migration of people between the two countries have led to the fresh outbreak of the mosquito-borne disease in the district. No information of how many people were affected was available.


California On Alert For Yellow Fever Carrying Mosquitoes

Californians have been warned to be on lookout for yellow fever-carrying mosquitoes, which are most commonly found in hot tropics of the world, as well as southeastern states of the US.

Aedes aegypti, a type of mosquito that carries the disease, was first found in June in the city of Madera, California. The mosquito bites during the day and are capable of reproducing simply by laying eggs in less than a teaspoon of water.

Despite eradication efforts to warn people of standing water that can allow these insects to lay its eggs, more mosquitoes were soon discovered in Clovis, Fowler, as well as San Mateo County in August. This week, the pest was found in Fresno.

Yellow fever-carrying mosquitoes are also capable of harboring dengue fever; both diseases are viral that can be fatal if not treated appropriately. Yellow fever causes severe flu-like symptoms, at times jaundice as well. Dengue fever causes headaches, body pains, and a rash similar to what patients get when diagnosed with measles.


Bubonic Plague Still Kills Thousands

Bubonic plague, the deadly scourge that wiped out half of Europe during the Middle Ages, still lurks in pockets of the globe, new research suggests.

Although plague is now rare in Europe, it recently sickened more than 10,000 people in Congo over a decade, and cases still occasionally emerge in the Western United States, according to a study published Sept. 16 in the American Journal of Tropical Medicine and Hygiene.

The plague bacteria, Yersinia pestis, had lain dormant in China’s Gobi Desert for centuries. But in the 1300s, it emerged with a vengeance, fanning out via trade routes from Asia to Europe and killing millions of people along the way. The plague was transmitted by fleas harbored by rats, which flourished in the overcrowded, filthy cities of the Middle Ages. By the end of the 1500s, between a third and half of Europe’s population had died from the Black Death. [Pictures of a Killer: Plague Gallery]

Even during the 1900s, the plague still killed millions of people, but since then, the advent of better hygiene in cities and swift treatment with antibiotics has reduced this erstwhile killer into a rare disease.

Still, plague outbreaks still flare up around the world.

According to the new study, which tallied the reported cases of plague around the world between 2000 and 2009, more than 20,000 people became infected during that time. People contracted the disease via rodents, bad camel meat and sick herding dogs, the report said. Cases in Libya and Algeria re-emerged after decades of absence.

The biggest burden was in Africa: in Congo 10,581 people contracted plague, followed by Madagascar with 7,182 cases and Zambia with 1,309 cases.

In the United States during that time period, 56 people contracted the plague and seven died. The cases occurred mainly because plague has become endemic in squirrels and wild rodents in the American West. Two of the fatalities were scientists: one who had conducted an autopsy on a wild mountain lion, and another who worked with plague bacteria in the lab.

Despite being a hotbed of plague in times past, Europe logged very few cases of the disease in the past decade. That may be because European cities keep their rodent populations in check, so the potential hosts for plague aren’t as prevalent, the researchers said.
