Seasonal transmission of Leishmania (Leishmania) mexicana in the state of Campeche, Yucatan Peninsula, Mexico

Abstract

In the Yucatan Peninsula, Mexico, localized cutaneous leishmaniasis (LCL)

Comparison of small mammal prevalence of Leishmania (Leishmania) mexicana in five foci of cutaneous leishmaniasis in the State of Campeche, Mexico

“…A strong seasonality in the transmission was demonstrated when the appearance of CL symptoms in both humans and rodents was correlated with the abundance of the antropophilic Lutzomyia cruciata in a Campeche focus 3,11 . In the southern humid forest of the Yucatan Peninsula, transmission of L. (L.) mexicana is limited to the months of November to March, when both high humidity and lower temperatures result in a high abundance of adult sand flies concurrent with the multiplication of parasites in the base of rodent tails 3,17,42,43 .…”

Eco-Epidemiological and Immunological Features of Localized Cutaneous Leishmaniasis in Southeastern Mexico: Thirty Years of Study

“…In the Yucatan Peninsula, a well-defined transmission season has been demonstrated, which is limited to the coolest months of the year, from November to March [35]. Thus, an important step to demonstrate a primary reservoir in an area of seasonal transmission is that the individuals of the reservoir species survive the infection and keep the parasite until the next transmission season, which is more than 7 months.…”

“…Based on this rationale, all the results of previous research were analysed focusing on the timing of transmission of L. (L.) mexicana in the state of Campeche, Peninsula of Yucatan, Mexico [35]. The study included the timing of incidence of LCL in humans during 1993-1994, as well as the rate and time of infection in rodents and sand flies between February 1993 and March 1995.…”

Nitric oxide production by Peromyscus yucatanicus (Rodentia) infected with Leishmania (Leishmania) mexicana

“…108(2): 172-177, April 2013 Cutaneous leishmaniasis (CL) caused by Leishmania (Leishmania) mexicana Biagi, 1953, emend. Garham, 1962, is a seasonal wild zoonosis that is endemic in the Yucatan Peninsula, Mexico (Andrade-Narváez et al 2003). In this area, CL, known as "chiclero's ulcer", produces a single ulcer in 84.5% of patients and is commonly (39.9%) located on the ear lobe (Seidelin 1912, Canto-Lara et al 1998, Andrade-Narváez et al 2001.…”
