Lutzomyia Wellcomei

Article on the topic: "Lutzomyia wellcomei: a mosquito species transmitting the causative agent of cutaneous leshmaniasis in South America"

Greetings to all nature lovers! In our article today, we will tell you about an unusual and important species of insect, which is a carrier of one of the most dangerous human diseases caused by parasitic tapeworms - leishmania. This species of mosquito is known as Lutzomyia wellecomei and lives in some regions of South America.

Lutzomyia welkcomei is a member of the family Phlebotomeidae, a group of insects that includes other mosquito species and enjoys significant epidemic consequences. They play the role of the main carriers of parasites in mammals, including some species of rodents, reptiles, birds and other animals in tropical and subtropical regions of the planet.

The transmission of Lutzomyias wellecomes in many parts of the world is a major public health and agricultural concern. In South America, these insects carry skin parasites that can be fatal to humans. One of the most common types of parasites of this nature is Leishmania dermatosis, an infectious disease caused by a parasite called Leishmania. It can cause skin rashes, redness, itching, lymph nodes, ulcers, and even failure due to the body losing too much fluid and nutrients.

The first clinical signs of the disease are usually observed within a few weeks after the bite of the L. wellecomes mosquito or

The mosquito of the genus Lutzomyius was previously classified as a species and caucasian of the genus Trinervion and was morphologically close to the species caucasica, caviae and sub-equatorialis. These were the so-called flat mosquitoes from the family Phlebotomiidae. These have been associated with Leshmania cutaneous signs. It was identified as the first host or agent of Leishmania disease (Leishmania braziliensis) (2).

In addition, it has also been associated with tryponosomal symptoms of leprosy (M. leprae) and human piumatosis (P. falciparum) (see Fig. 2). Subsequent molecular genetic studies of the mosquito, as well as analysis of data on the entire genus Lutzomyias, showed that the species L. wellcomei, braz (L. serrana) and serrania (L. serricans) form three subgenera. The definition of subgenera is currently carried out mainly through the morphology of adults and eggs, comparative analysis of the mitochondrial genome and the study of eight multigene primer markers found on the X chromosome. Of the eight primers, at least three markers matched the L. cavalliense cavalier goose (L. cavalliense) or the L. longipal flathead crocodile.
