Gerns That Infect Both Humans And Pets
Silly question- can down feathers in pillows carry germs/diseases that can live/transmit to humans such as streptococcus pneumoniae?
The filling for: pillows (even down or feathers) goes through a sterilization process before being sold. If you are referring to a used pillow that someone else had been using, it would be potentially possible to transmit infection however in the absence of moisture it is unlikely that bacteria like strep pneumoniae would survive long enough to be transmitted. ...Read more
Personal contact: Research is incomplete, but so far transmission to humans from animals (mostly birds) has been uncommon (happily) and mostly personal contact. Airborne transmission does not seem important at this time, but there is fear this could change if the virus mutates. If so, and if highly transmissible (i.e. infection by only a few virus particles), the world could see major epidemics. Fingers crossed! ...Read more
Will new zoonotic diseases that jump from animal to human cause the extinction of all mankind in the future?
Plague: Anything is possible. You're question may be more entertainingly answered by Michael Crichton, who is a medical doctor, by the way. ...Read more
Are any human diseases transmittable through mosquitos? From human to mosquito then back to human?
If humans evolved from apes.Why human body is not as strong as apes or chimpanzees?How to make our bodies(bones and muscles) stronger?
Apes/chimps: Humans are not apes or chimps! Yes, they are strong but would have little to do with you. At your age I strongly recommend you go to a nearby training program. You will be pleasantly surprised and let many of your friends know how good and straightforward it is. ...Read more
Why does consuming the flesh of another human make us ill and catch kuru but we can still eat other animals?
If a human has been infected with pasteurella multocida from a dog can they pass it onto other humans they're in close contact with?
No: If you were infected with pasteurella, you probably got treated for that infection and you don't even have it in your system anymore. ...Read more
What are some common genera of pathogenic bacteria that have no species found in the human body naturally? Borrelia? Brucella? Yersinia? Mycoplasma?
The Microbiome... : Great thought question. However, you are assuming we know all the community of species of bacteria in the body (aka. The microbiome). Recently, we have discovered thousands of genera in our body through molecular techniques (most don't even have a name yet). Though it's tempting to generalize, the question you pose can't be answered with any reliability with what we know today. ...Read more
Can animals such as cats carry streptococcus pneumoniae and give it to a human causing bacteremia?
Are all bellybuttons proportionally in the same spot across the human species? Can you share some sources?
Apparently.: There are no studies that say differently. There are congenital deformities that may affect location and appearance., some may have increased incidence in certain populations. Good question, but I can find nothing suggesting any differences, based on ethnicity. ...Read more
Rabies infection: The cdc states: all species of mammals are susceptible to rabies virus infection, but only a few are reservoirs for the disease. Distinct strains of rabies have been identified in raccoons, skunks, foxes, coyotes and several species of insectivorous bats. Transmission of rabies begins when infected host saliva is passed to an uninfected animal through a bite or mucous membranes, eyes, or mouth. ...Read moreSee 1 more doctor answer
If cold/flu transmit via "aerosolized", then why do some people not get infected when living with those afflicted in close quarters? Are they immune?
Do doctors believe we humans evolved
from a common ancestor of apes and humans?Will we evolve into other forms in future?
Some do, some don't: Doctors are like other people, in that some believe we evolved from a more primitive species, but others believe we were created as modern humans. In either case, we have been evolving and will continue to evolve, ever since the days of the first humans. Doctors who believe we were created as humans, see that we are evolving, but just into slightly different humans, not into another species. ...Read more
Can you tell me how antibiotics used in animals and agriculture lead spreads of resistant strains to human populations?
Two ways: Giving antibiotics to animals will kill many bacteria, but resistant bacteria will survive and multiply. When the animal is slaughtered and processed, these bacteria can contaminate meat and humans who handle it. Also, bacteria can reach the environment/water and plants via animal feces, which we can then ingest. This way we "inherit" the resistant organism. ...Read more
Maybe, maybe not: It would be hard to definitively document in animals, the same symptoms humans suffer. Diagnosis in humans requires a great deal of communication about complex experiences. Our language and understanding fail us, with animals. Still, seeming anxiety and repetitive behaviors show up in pets and other animals in captivity -- birds pulling out feathers, acral lick dermatitis & granulomas in dogs. ...Read moreSee 1 more doctor answer
