Being able to tell the difference between, say, a fleabite, a bed bug bite, and a mosquito bite can mean the difference between an infestation (fleas, bed bugs) and figuring out whether the ...
Both fleas and bed bugs can bite and snack on your blood, causing severe itching and raising your risk for an infection or allergic reaction. Knowing the difference between bed bug bites and ...
There are more than 2,000 species of tiny (0.04 to 0.15 inches), wingless, blood-sucking fleas that live on the body of the host they infest. Although fleas cannot fly, they have developed ...
It is caused by the bacterium Rickettsia typhi, and is transmitted by the fleas that infest rats. While rat fleas are the most common vectors, cat fleas and mouse fleas are less common modes of transmission. These fleas are not affected by the infection. Human infection occurs because of flea-fecal contamination of the bites on human skin.
The exposure to a flea bite from an infected flea may cause bubonic plague in humans that could develop into the septicemic plague. Cats and dogs were also susceptible to bites from infected fleas. These cats and dogs could then expose humans to the plague when the animal brings those infected fleas around people. [4]
By stage 2 (day 1–2), penetration is complete and the flea has burrowed most of its body into the skin. Only the anus, the copulatory organs, and four rear air holes in fleas called stigmata remain on the outside of the epidermis. The anus will excrete feces that is thought to attract male fleas for mating, described in a later section.
A flea's mouth has two functions: one for squirting saliva or partly digested blood into the bite, and one for sucking up blood from the host. This process mechanically transmits pathogens that may cause diseases it might carry. Fleas smell exhaled carbon dioxide from humans and animals and jump rapidly to the source to feed on the newly found ...
