IntroductionDiseases are classified into transferable (or irresistible) and nontransferable forms, each of which has its own distinct causes and is transmitted in unexpected ways. One of the main contrasts between these two types of diseases is that communicable diseases can be passed from one individual to another, although in the case of non-transferable diseases, they do not infect the next individual. Another significant contrast is the vehicles of transmission in which vectors play a vital role in disease transmission, while neighborhood condition, dietary habits and lifestyle are also important in the origin of non-communicable diseases .

Around 20 types of Leishmania have been recorded to have influenced more than 12 million individuals worldwide. Skin lesions have been reported to be the most common. The parasite requires specific receptors on macrophages. The most considered receptors for Leishmania phagocytosis are the third supplement receptor (CR3). The first supplement receptor (CR1) is the mannose receptor (MR), Fc receptor (FcR), and fibronectin receptors (FnR). In all cases, understanding these receptors is important to understand the characteristics of the contamination. Leishmania are intracellular protozoan parasites transmitted by the sandfly vector and taken up by phagocytes for their intracellular replication. A special receptor is formed on the host macrophage, which effectively contributes to its attachment. The most studied receptors for Leishmania phagocytosis are the third supplement receptor (CR3), the first supplement receptor (CR1), the mannose receptor (MR), the Fc receptors (FcR), and the fibronectin receptors ( FnR). The role of these receptors is not fully understood nor their link to parasite survival. Leishmania parasites have their place in the kingdom Protists, class Kinetoplastea, subclass Metakinetoplastina, family Trypanosomatidae, subfamily Leishmania and genus Leishmania. A wide range of leishmaniases are transmitted by parasitic female sandflies, Phlebotominae. Around 700 species of sand flies have been represented and grouped into six genera. Three of these genera were found in the New World (Warileya, Lutzomyia and Brumptomyia) and three (Phlebotomus, Chinius and Sergentomyia) in the Old World. Among these six genera, Lutzomyiah and Phlebotomus are responsible for the transmission of Leishmania. Leishmania can be transmitted without these genera, for example by incidental contamination of a laboratory or by blood transfusion. As reported by Killick-Kendrick (1990) and Young and Arias (1991), 88 Lutzomyiah and 39 Phlebotomus types have been confirmed as transmitters of Leishmania vectors. Sandflies are found in dry and semi-dry territories. Thus, sandflies can be found in dry and semi-dried areas (e.g. dividers and rat tunnels) and in tropical forests (e.g. in the openings of tree trunks or in the litter of leaves). Sandflies are 1.3 to 3.5 mm long with dark to dark color shades. They are described by their thick hairy wings which are held in an upright V shape on the body. Male and female sandflies can be recognized by visible pairingclasps towards the end of the male's intestines, while in the female the mouthparts are modified to cut the vertebrate's skin. Sandflies breed in dark, damp areas, for example in rat tunnels and leaf litter. The female sandfly is the primary transmitter of the Leishmania parasite, as it feeds on the blood of vertebrates for egg progression, as well as plant juices, sap, and honeydew. The male sandfly feeds on plant juices, sap and honeydew, but not blood. Sandflies jump instead of fly. Female sandflies have been found more than males, perhaps due to their larger appearance. Female sandflies have been discovered in areas such as rodent tunnels, dividers, and creature shelters. Such situations provide the necessary warmth and viscosity to the progressing stages of sandfly eggs. The development of sandflies can be characterized in four main stages: egg, hatchlings, pupae and adult. Female sandflies lay 80 to 100 normal-sized eggs of 0.3 to 0.4 mm on different surfaces. Newborns feed for about two weeks. Therefore, sandflies move into the pupa stage and begin to transform into a caterpillar with developed wings and eyes. After about five to ten days, the adult sandfly stands up and is ready to snack. Adult female sandflies are most dynamic at sunset. Low humidity, high temperatures and ocean conditions encourage hatchlings to be born. Female sandflies breed in areas with high relative humidity, for example along stream banks or near water reservoirs. Conducted an examination in Bihar, India and found that the banks of waterways provided the best natural environment for sandflies to rest and breed and found large quantities of hatchlings. studied 79 water wells in Greece and found that 37 of them were home to sandflies. Similarly, we examined possible environments for sandflies in the state of Bahia, Brazil. Their results showed that the highest thickness of sandflies was collected in areas near water reservoirs. Leishmaniases are vector contaminations caused by Leishmania, affecting different warm-blooded animals, mainly carnivores. Patent clinical disease is generally simple to analyze by finding the parasite in clinical samples. In subclinical cases, recognition of the parasite is done using delicate methods. Various atomistic strategies have been produced and evaluated, including multilocus compound electrophoresis, polymerase chain response (PCR)-based assays, real-time quantitative PCR, and rearranged PCR techniques. Around thirty species of Leishmania have been discovered, 20 of which are considered infectious to humans. The ability to recognize Leishmania species is essential for the separation of different types of conditions (instinctive, cutaneous, mucocutaneous). The Leishmania parasite exchanges between crawling and vertebrate hosts, with interspecific transmission occurring through female sandfly nibbling. It is either zoonotic or anthroponotic, depending on the types of Leishmania parasites involved. Generally, there are no less than twenty types of Leishmania parasites that infect humans with unique parasites. There are four basic types of Leishmaniasis caused by Leishmania parasites which are: Visceral (VL), Cutaneous (CL), Diffuse Cutaneous (DCL). and MCL mucocutaneous leishmaniasis. The LV is considered to bethe most extreme form of leishmaniasis if not treated quickly and effectively. It has a great impact on many parts of the body and the actual side effects are enlargement of the spleen and liver, sensational weight loss, change in skin color, pancytopenia. This problem is found in dry areas of the Mediterranean and South America, East Africa, China, the Indian subcontinent and some parts of the Middle East. CL causes a change in skin color and pancytopenia. CL is the most common leishmaniasis, causing injuries to exposed parts of the body. It is cured and the contamination frequently disappears within a few months, leaving permanent scars. It is clear that leishmaniasis is a widespread infection that affects a large number of countries, mainly in tropical and subtropical areas. The life cycle of Leishmania involves crawling (sandfly) and vertebrate stages. The life cycle begins when the female sandfly sucks blood and infuses the promastigote into the body, which attacks selected host cells, mainly macrophages. Promastigotes transform into amastigotes inside macrophages. The amastigotes duplicate in cells and attack distinctive tissues, the sand fly sucks the blood and thus ingests the amastigotes. In the midgut of the sandfly, the parasites transform into promastigotes. These promastigotes move towards the tube and the cycle begins again. Leishmaniasis is a global infection, known to affect 88 countries. According to WHO (2013c) and El-Beshbishy (2013), 90% of CL cases occur in Afghanistan, Algeria, Brazil, Iran, Peru and Saudi Arabia, while 90% of VL cases occur in Bangladesh, India, Nepal, Sudan and Brazil. Although sandflies are primarily found in warm climate zones around the world, their dispersal extends from north to southwest Canada. The main causative agents are anthroponotic cutaneous leishmaniasis (ACL) and zoonotic cutaneous leishmaniasis (ZCL). CL disease is endemic in Khorasan Razavi Territory and other nearby urban communities. Amid (2014) reported 68,958 CL cases in Mashhad city. ACL emerged as the most imperative endemic contamination. Species identification is fundamental to choose the best possible treatment for different types of contamination and to control the disease in an area. The coordination strategy is the most important system used for patients related to Leishmanial injuries. Many distinct PCR targets, including coding and non-coding intergenic areas of the gp63 locus, exon (SLME), and SSU rRNA, have been used for parasite recognition. PCR is considered the most effective technique for diagnosing leishmaniasis. There are methods of treating cutaneous leishmaniasis, including physical strategies, for example using infrared, solidification or electrotherapy. Medications that may be used include antimony mixtures and hypertonic NaCl. Topical aids are also used for treatment. These treatment strategies are used in cases of wounds. The fundamental treatment of cutaneous leishmaniasis is demonstrated in the presence of various wounds. There is no effective treatment for CL. Regardless, these medications are costly and may be associated with a variety of real-life reactions. Ketoconazole, a broad-spectrum antifungal, has been shown to be viable in CL. However, these medications are expensive and may be associated with a variety of real symptoms. Ketoconazole, a broad-spectrum antifungal, has been used inCL. Treatment sometimes results in potential hepatotoxicity. Scratching is significantly less demanding and less gruesome for the patient. After the wounds are cleaned with water, 1% lidocaine anesthesia is administered and the tissue is scraped for a skin test. Scraping is done to obtain enough exudate for testing. The dermal tissue is then fixed on a slide. Biopsy is the primary strategy for distinguishing conditions other than leishmaniasis from non-ulcerative skin wounds. For luiopsia, a surgical blade is used to evacuate some tissue from the edge of the wound, the tissue is then spread over the blade. These slides are stained with Giemsa and viewed under a microscope. Biopsy tissue should be taken from the edge of the ulcer to incorporate both necrotic and appropriate tissue. Tissues may also be stained with hematoxylin and eosin, which in many examples is sufficient to show amastigotes. All slides should be analyzed using the oil immersion objective. Most amastigotes are round to oval and measure 2 to 3 µm in most measurements. Amastigotes contain a thin cell layer, cytoplasm, nucleus, and a pole-molded kinetoplast. To distinguish an amastigote, each of these 4 structures must be present. Preventing people from interacting with sandflies' living spaces is relatively inconceivable. This is primarily due to the great diversity of sandflies' environments and, furthermore, the great flexibility of sandflies towards other new territories. What makes maintaining a strategic distance from sandflies even more difficult is the lack of awareness of the closeness of humans and sandflies. Sandflies are found to exist in human settlements, urban areas and inside homes. Colonies and urban development may attack some normal sandfly living spaces, providing more opportunities for sandflies in endemic territories. Given the challenges of controlling sandflies and the lack of prophylactic antibodies against any type of leishmaniasis, vector control remains the best method of combating the disease. These control measures should be implemented by controlling vectors (sandflies) and rodents. Chloroquine is an antiprotozoal drug used in intestinal diseases that causes significantly fewer reactions when used with antimony mixtures. In a pilot investigation of 10 patients, intralesional chloroquine. Chloroquine has been used in the treatment of cutaneous leishmenosis. Zinc sulfate suppresses the development of promastigotes of L. major and L. tropica in vitor. Zinc sulfate helps improve cutaneous leishmenosis sores. The viability of zinc against promastigotes and amastigotes of both types of cutaneous leishmaniasis was studied and the immunomodulatory impacts of zinc may also represent the prophylactic part of zinc against cutaneous leishmenosis. The pentavalent antimonials, meglumine antimoniate (Glucantime) and sodium stibogluconate (Pentostam) are the main line of therapy used to treat leishmaniasis. It is wise to treat the sores because they may persist for some time, leaving unattractive scars. Although antimony is the main treatment, it is a mildly fatal drug. This has led many specialists to try different medications, such as hypertonic sodium chloride system, zinc sulfate, and metronidazole. Excellent results have been obtained with ciprofloxacin and some topical medications have also been..
