Do mosquitoes infect infectious bacteria, and are mosquitoes the source of infectious diseases?

Being bitten by a mosquito is not just a pimple, more than 80 diseases such as malaria and dengue fever are transmitted by mosquitoes.

At present, AIDS is said to be definitely not, and there is no relevant research to prove that AIDS can be transmitted through mosquito bites, and some other diseases should be possible, but I think as long as it is not bitten by mosquitoes, it should not be so easy to be infected, or there will be a seasonal onset of disease early, and mosquitoes generally suck enough blood once, and they will not suck blood again for 3 or 5 days, and some mosquitoes even end their lifespan, so there is generally no major problem.

Mosquitoes are intermediate hosts for Japanese encephalitis, haemofilariasis, and malaria and are contagious. Other diseases don't.

Mosquitoes are common in three genera: Anopheles mosquitoes, Aedes mosquitoes and Culex mosquitoes, and the common ones in Wuxi are Culex pale mosquitoes, Culex tribal mosquitoes, Aedes albopictus, Anopheles sinensis, etc., with Anopheles pale mosquitoes as the main ones (accounting for 61%), followed by Anopheles sinensis. The adult mosquitoes of Culex pale are medium in size, light brown in color, and the larvae breed in sewage pits, clear water manure pits and stagnant water in depressions, and the adult mosquitoes are blood-suckers, and this mosquito species is the vector of Japanese encephalitis and filariasis. Anopheles sinensis is the dominant mosquito species in rice-producing areas and an important vector of malaria and filariasis.

The adult mosquitoes of Aedes albopictus are small, black, with white spots, commonly known as "flower mosquitoes", and the larvae breed in bamboo tubes, tree holes, stone holes, clay pots and other water containers, and the adult mosquitoes suck blood during the day, which is an important vector for spreading Japanese encephalitis and dengue fever. The discovery and presence of these mosquito species does not necessarily mean that there will be transmission of related diseases, but there is a possibility of disease transmission when infectious patients and vector mosquitoes are present at the same time.

Bacteria cannot produce mosquitoes, but mosquitoes can carry bacteria to spread diseases to humans.

Mosquitoes are mainly produced in clean water that does not flow.

Mosquitoes are male and female, male mosquitoes have filamentous antennae, antennal hair is generally thicker than that of female mosquitoes, and their food is nectar and plant juice. The mouthparts of the male good potato mosquito are degraded, and the female mosquito needs to bite the animal to suck blood in order to promote the maturation of her eggs before breeding. There is a substance in mosquito saliva that relaxes blood vessels and anticoagulates blood, making it easier for blood to collect at the bite site.

After being bitten by a mosquito, the bite** often has acne and itching symptoms. Almost everyone has the unpleasant thing of being bitten by a mosquito. In fact, it should be said that they were "bitten" by mosquitoes.

Mosquitoes can't open their mouths, so they don't take a bite on them, in fact they pierce people with six needle-like structures, and these short needles are the center of the mouthparts that mosquitoes use to feed. These short needles suck human blood like the needles used to draw blood; Mosquitoes also release saliva containing anticoagulants to prevent blood from clotting so that they can calmly feast on a good meal.

Newborn mosquitoes can only take off if their wings are stiff, and within 24 hours of emergence, all males turn 180 degrees after the eighth abdominal segment to complete the mating position. The act of mating varies from species to species, with some forming swarms of dancing mosquito poles in an open field or meadow at dusk. Mosquito poles are not necessarily made from a single male mosquito, but are usually made from a cluster of several different mosquitoes.

At this time, the female mosquito sees the group dancing, so she flies to the vicinity of the mosquito outpost, mates with the male mosquito of the same species, and leaves.

Mosquitoes can carry germs and can also spread germs, but bacteria cannot produce mosquitoes.

Mosquitoes are the route of transmission. A source of infection is a person or animal capable of transmitting a pathogen, i.e. he himself contains the virus; Mosquitoes play a role in a way, which is the way for pathogens to leave the source of infection to feast on humans or animals, and it itself can not be infected with the disease, but can only be transmitted to other people through the bloodstream, which is a biological vector. AIDS (HIV) cannot be transmitted through it.

But in some biology exercises, it is grouped into two categories.

Pathogens of mosquitoes are not only a route of transmission but also a source of infection!

Let me first clarify the concept of the source of infection and cutting off the route of transmission:

Infectious agent: refers to a person or a grinder animal whose body has a pathogen that grows, multiplies, and is able to excrete the pathogen. This includes sick people, pathogen carriers, and infected animals.

Mode of transmission: The process in which the pathogen is excreted from the body from the source of infection, and through a certain mode of transmission, reaches and invades the new susceptible person, which is called the transmission route.

Pathogen-carrying mosquitoes are both animals that excrete pathogens and pathways that can be transmitted to new susceptible people, so pathogen-carrying mosquitoes are not only a route of transmission but also a source of infection.

It's one of the other sources of infection.

Mosquitoes have certain benefits for humans, but the benefits are very small, and mosquitoes play a relatively large role in the ecological balance of nature. <>

Many people hate mosquitoes very much in their lives, because especially in summer, mosquito bites will make people feel very itchy and painful, especially when sleeping, mosquitoes will also make a slight noise.

But mosquitoes have some benefits for humans, but these benefits are very small. We all know that the world we exist in has a complete ecological chain, and if one link in the ecological chain is destroyed, there will be a chain reaction of dominoes in the entire ecological chain. Writing is also a link in our ecological chain, and its existence is beneficial to people.

First of all, the presence of mosquitoes can spread diseases and thus control the population of some animals, which is somewhat unrealistic, but it does exist in some tropical areas, especially in tropical rainforest areas. Creatures in the tropics are very ferocious, including mosquitoes. <>

Similarly, if mosquitoes can prey on other animals, then there are also animals that hunt mosquitoes for a living, such as some frogs, fish, and birds all live by eating mosquitoes, in fact, bats and sail gecko spiders in our daily life are all dependent on eating some flying insects and animals to survive.

The presence of mosquitoes can maintain the balance of the biosphere, and for humans, although mosquitoes feed on human blood, the body will also resist when humans are sucked. To put it simply, after being bitten by a mosquito, the body's immunity will continue to increase, and when the mosquito bites, a small amount of germs will be brought into the human body, and the human immune system will respond at this time and produce antibodies to fight the bacteria. Even if the same germ is present next time, there will be no major disease when it enters the human body.

Thankfully, mosquitoes only appear in the summer, at least in the winter.
