Study of cutaneous leishmaniasis in the State of Campeche Yucatan PeninsulaMexico, over a period of two years. To study cutaneous leishmaniasis CLin the Calakmul municipality of the Campeche State, during two years. Individuals with skin lesions were evaluated.
Aspirates taken from the lesions were cultured, PCR was performed to diagnose the Leishmania species. CL is an important public health concern in Calakmul, and the parasite causing it belongs to Leishmania mexicana and Leishmania braziliensis complexes. American cutaneous leishmaniasis; Campeche, Mexico. Leishmaniasis is caused by the protozoa Leishmania sp. The World Health Organization WHO estimates the worldwide prevalence of leishmaniasis to be approximately 12 million cases, with annual mortality reaching 20 Leishmaniasis has a worldwide distribution and is present on four continents in 88 countries, where the size of the population at risk is about million.
An estimated to new cases of VL occur worldwide each year. Cutaneous leishmaniasis CL is the most widespread clinical form of the disease. It is presented as a spectrum of clinical manifestations, such as primary localized skin lesions with frequent findings of amastigotes LCL that can self-heal usually in individuals with an effective immune response. However amastigotes parasites can disseminate from the skin lesions to the nasopharyngeal leishmaniadis and cause secondary wounds with progressive destruction of mucosal and submucosal tissues, with rare findings of amastigotes typical lesions of mucocutaneous leishmaniasis MCLor disseminate to the entire body as nodular lesions usually cuutanea of parasites DCL.
In endemic regions, multiple species of Leishmania may co-exist. In Mexico, CL is the most wide spread form of leishmaniasis. It is distributed in several states, with the main endemic areas located in the southeast of the country.
LCL, also known as “chiclero’s ulcer” in southeastern Mexico, was described by Seidelin in the sylvatic region of the Yucatan peninsula. Therefore, early differential diagnosis of CL and the identification of the Leishmania strains are important for monitoring clinical outcome and adequately targeting treatment. Furthermore, diseases with other causes but with a clinical manifestation similar to that of leishmaniasis e.
Molecular diagnosis for cutaneous leishmaniasis has been extensively developed, essentially by PCR-based methods. PCR also has leishmsniasis to be a very successful tool in molecular diagnostics leishmaniasus the field e.
In this study parasitological diagnosis procedures, such as medium cultures as well as DNA analysis using PCR, were used to establish the accurate diagnosis of CL and identification of Leishmania species over a period of two years in Calakmul leishaniasis, Campeche state, Mexico.
The study area was the forest of the state of Campeche, Mexico. LC is endemic to this area. Calakmul, the largest municipality located in the state of Campeche, is situated in the most southern part of the Yucatan Peninsula, bordering with Guatemala and Belize. Calakmul is located within the Peten biogeographic province, which also comprises northern Guatemala and Belize.
Informed consent was obtained from all the adults who participated in the study. Consent for inclusion of young children was obtained from parents or guardians. The study was registered in the “Libro de Actas del Cabildo” with date May 24, One hundred and forty-six individuals with skin lesions suggestive of Leishmania infection were studied.
Leishmania reference strains and culture conditions. The following cutanfa were used as positive controls: PCR amplifications were performed in a solution of 0. A total of CL diagnosed patients accepted treatment with meglumine antimoniate Glucantime.
Glucantime is marketed ccutanea 5-ml ampules containing 1. Treatment consisted in one ampule by intramuscular injection per day until healing.
DNA from eight 7. A complete response to treatment was defined as a complete re-epithelization of all lesions with no residual erythema and no relapses during the monthly follow-ups for a period of two years.
Leishmaniasis is considered by many experts to be cutannea emergent disease in some areas and in others as a re-emergent disease because over the last 20 years the number of cases of all forms of leishmaniasis throughout the world has soared.
This result agrees with those found for Kumar 11 in Cutane where This result could stem from several factors: From this part of Calakmul in Union 20 de Junio locally referred to as La Mancolona cases infected with each of these strains of Leishmania were found cutanfa I. In southern Calakmul Regarding skin lesions, in most of the patients they were rounded and ulcerated, with elevated borders and necrotic center.
There were no leisgmaniasis metastases and neither lymphatic involvement nor mucosal involvement was observed in any of the cases figures 1a1b and 1c. The village most severely affected with CL was Dos Lagunas Sur, located in the southern part of Calakmul, close to the border of Belize, with People in this village farm chili crops around their houses, which are located very close to the forest, and the population affected includes all of its sectors: In central Calakmul, La Guadalupe village had the highest prevalence rate 2.
In northern Calakmul the most affected communities were La Mancolona with a 6.
La Virgen, with 3. These villages are located km away from the crops and are more urbanized due to deforestation figure 2a. The doses needed to obtain complete healing of lesions varied in children from 2 to 20 and in adults from 2 to 67 ampules table III. Two patients, one child from Narciso Mendoza 14 years old and one adult from Dos Naciones 30 years old were cured spontaneously.
No statistically significant difference was observed among patients infected with L. Among the conditions that have been reported as risk factors by several authors, that explain the permanent presence, spread, and increase of CL cases in Calakmul, Campeche and the presence of L.
Furthermore Canto-Lara 29 identified L.

Moreover it has been demonstrated that reservoir mammals of several orders can be infected with the same Leishmania species. In conclusion, zoonotic cutaneous leishmaniasis ZCL caused by L. Leishmaniais it was stablished by Desjeux 31 these factors are making ZCL a growing public health concern for many countries of the American continent.
The findings in the present study showed that CL is still an important public health concern in the Municipality of Calakmul, Campeche, Mexico.
This is due maybe to ecological, social and educational conditions favorable to peishmaniasis permanence and transmission of LC. Hernandez Rivera was fellow of Conacyt Mexico.
