KLAMATH FALLS, Ore. (Reuters) - Seven employees of an Oregon zoo contracted tuberculosis from three elephants in their care in 2013, the U.S. Centers for Disease Control and Prevention said on Friday.
The staff members at the Oregon Zoo in Portland were infected with a latent form of the respiratory illness and therefore displayed no symptoms and were not contagious, a report published by the CDC said.
The report was issued two days after a U.S. judge ordered the CDC to release documents on tuberculosis in elephants to animal-rights group People for the Ethical Treatment of Animals. Oregon health officials said the timing of the report was unrelated to the lawsuit.
PETA sued the U.S. Department of Health and Human Services, parent of the CDC, last year. It sought release of data because of what it said was a serious risk that elephants could spread the potentially deadly disease to other elephants or to humans.
The CDC report on the outbreak pointed to a lack of research about tuberculosis in elephants. It also called for improved screening to detect the disease because the present method of detection - taking cultures - may miss some cases or result in false positives.
Jennifer Vines, deputy health officer for Multnomah County, whose office worked with the CDC on its report, said the investigation did not conclude that tuberculosis is highly transmissible between elephants and people.
About 5 percent of captive Asian elephants in North America, like the ones in Portland, are believed to have tuberculosis, the CDC said. Human-to-elephant transmission was first identified in 1996 and there have been a handful of cases in recent years in Tennessee and elsewhere.
The outbreak prompted the Portland zoo to say it would conduct more frequent tuberculosis tests of both animals and staff through at least June 2016.
The outbreak was identified in May 2013 when a routine annual check of elephants found that a 20-year-old bull named Rama was infected.
Rama's father, 51-year-old Packy, also tested positive as did Tusko, a 44-year-old former circus performer.
Public health officials do not know the cause of the outbreak. The CDC said it was possible that a zoo volunteer diagnosed with tuberculosis in 2012 may have spread the disease to the elephants.
The zoo's other elephants were not infected, nor were another roughly 100 people who were near the three sickened bull elephants.

KLAMATH FALLS, Ore. (Reuters) - Seven employees of an Oregon zoo contracted tuberculosis from three elephants in their care in 2013, the U.S. Centers for Disease Control and Prevention said on Friday.
The staff members at the Oregon Zoo in Portland were infected with a latent form of the respiratory illness and therefore displayed no symptoms and were not contagious, a report published by the CDC said.
The report was issued two days after a U.S. judge ordered the CDC to release documents on tuberculosis in elephants to animal-rights group People for the Ethical Treatment of Animals. Oregon health officials said the timing of the report was unrelated to the lawsuit.
PETA sued the U.S. Department of Health and Human Services, parent of the CDC, last year. It sought release of data because of what it said was a serious risk that elephants could spread the potentially deadly disease to other elephants or to humans.
The CDC report on the outbreak pointed to a lack of research about tuberculosis in elephants. It also called for improved screening to detect the disease because the present method of detection - taking cultures - may miss some cases or result in false positives.
Jennifer Vines, deputy health officer for Multnomah County, whose office worked with the CDC on its report, said the investigation did not conclude that tuberculosis is highly transmissible between elephants and people.
About 5 percent of captive Asian elephants in North America, like the ones in Portland, are believed to have tuberculosis, the CDC said. Human-to-elephant transmission was first identified in 1996 and there have been a handful of cases in recent years in Tennessee and elsewhere.
The outbreak prompted the Portland zoo to say it would conduct more frequent tuberculosis tests of both animals and staff through at least June 2016.
The outbreak was identified in May 2013 when a routine annual check of elephants found that a 20-year-old bull named Rama was infected.

The zoo's other elephants were not infected, nor were another roughly 100 people who were near the three sickened bull elephants.
The study also revealed that individuals who quit smoking, regardless of age, can achieve a life expectancy similar to non-smokers within approximately 10 years after quitting, and nearly half of this benefit can be noticed within just three years.
Researchers found that a combination of genetics and environmental factors reduces longevity in dementia patients. The same combination may shorten the lives of their siblings even without dementia.
The suicide rates increase substantially when air pollution rises, and the effect was particularly strong in the elderly, with older women 2.5 times more at risk than other groups.
While mental stress is commonly acknowledged in connection with grief, it is crucial to understand that grief can also present physical symptoms, including illnesses, fatigue, pain, and sleep disturbances.
The use of antidepressants, particularly fluoxetine, could affect the development of the prefrontal cortex of the infant's brain, potentially raising the risk of mental health disorders later in their life.
Researchers have developed smart earrings that could continuously monitor a person's earlobe temperature. The innovation known as Thermal Earring could also be potentially used to track signs of ovulation, stress, eating, and exercise.
The researchers made the interesting finding using a trial involving patients with a rare genetic condition called Alpha-1 antitrypsin deficiency (AATD).
People infected with the flu were more likely to need hospital care in the following year for common neurologic conditions than people who had the SARS-CoV2 infection.
Among women with a history of pregnancy complications, those who achieved or maintained high heart health after pregnancy were at a similar risk for heart disease as women without adverse pregnancy outcomes and good cardiovascular health, the study stated.
The study published in the journal BMJ indicated that individuals with hypermobile joints had a 30% higher chance of not fully recovering from COVID-19 and experiencing persistent fatigue associated with long COVID.
The studies showed that COVID antigens lingered in the blood up to 14 months after infection and more than two years in tissue samples of people who had the infection.
Those individuals who receive a COVID-19 vaccine during the first half of their menstrual cycle are more likely to experience cycle length changes than those receiving a vaccine in the latter half.
