First evidence of systemic infection and specific cytotoxic T lymphocyte immune response evoked by oral infection with recombinant Salmonella enterica serovar Albany-Ovalbumin in C57BL/6 mice.

Our group isolated Salmonella enterica serovar Albany from food and feces of wild captive carnivores in a zoo from northwestern Mexico. This serovar was also associated with the death of an ocelot (Leopardus pardalis) in the same zoo. Another group associated S.

The plasmacytoid dendritic cells evoke Salmonella-specific CTL effector response.

Introduction: The immunological role of plasmacytoid dendritic cells (pDC) in bacterial infections such as Salmonella has been poorly documented. Therefore, we analyzed the effector function of these cells by presenting cytotoxic T lymphocytes (CTL) with Salmonella Typhimurium antigens. Objective: To analyze the Salmonella-specific CTL response evoked by pDCs.

First report of autochthonous canine leishmaniasis caused by Leishmania (L.) mexicana in Sinaloa, Mexico.

Leishmaniasis is a neglected tropical disease caused by different species of protozoan parasites of the genus Leishmania. Dogs have been proven as primary hosts of the parasite. Cases of cutaneous leishmaniasis in humans caused by Leishmania mexicana have been reported in Sinaloa; however, the vectors and hosts involved in the epidemiology of the parasite in northwestern Mexico are still unknown.

High frequency of HPV16 European variant E350G among Mexican women from Sinaloa.

Background & Objectives: Human papillomavirus (HPV) infections play a crucial role in the aetiology of cervical cancer (CC), and HPV16 is the primary viral genotype associated with CC. A number of variants of the HPV16 E6 gene are involved in the progression of CC, differing in their prevalence and biological and biochemical properties. This study was designed to determine the frequency of HPV types 16/18 and to identify the presence of HPV16 E6-variants in asymptomatic Mexican women.

Bacteriophage cocktail for biocontrol of Escherichia coli O157:H7: Stability and potential allergenicity study.

Escherichia coli O157:H7 has become a global public health and a food safety problem. Despite the implementation of control strategies that guarantee the safety in various products, outbreaks persist and new alternatives are necessary to reduce this pathogen along the food chain. Recently, our group isolated and characterised lytic bacteriophages against E.

Prevalence of Salmonella enterica serovar Albany in captive zoo wild animals in the Culiacán Zoo in Mexico.

Salmonellosis is an important zoonotic disease but little is known about the role that free-living animals play as carriers of this pathogen. Moreover, the primary route of infection in the wild needs to be elucidated. The aim of this study was to determine the source and the route of transmission of Salmonella enterica serovar Albany (S.

Identification of immunodominant peptides from Gnathostoma binucleatum.

Gnathostomiasis is now recognized as a zoonosis with a worldwide distribution. In the Americas, it is caused by the third-stage larvae of Gnathostoma binucleatum and in Asia mainly by G. spinigerum.

[Reaction of Leishmania (Leishmania) mexicana antigens by sera of patients with cutaneous leishmaniasis from Sinaloa, Mexico].

Objective: To detect Leishmania mexicana antigens reacting with sera of patients with cutaneous leishmaniasis (CL).

Material And Methods: A crude extract of L. mexicana was used as antigen for 2-D Western blot using sera from 5 patients with CL and controls from Sinaloa, Mexico during 2008.

[Cutaneous leishmaniasis caused by Leishmania mexicana in Durango, Mexico: first clinical case report].

Background: Leishmanisis is a parasitic diseases caused by intracellular protozoan of Leishmania genus. These parasites are transmitted by the bite of phlebotomine flies. Leishmanises are classified in different clinic variants: cutaneous localized or diffuse, mucocutaneous and visceral.

[Tissular cestodiasis: role of helper type 1 and 2 t-lymphocytes].

Cysticercosis and hydatidosis are parasitic diseases caused by larvae of Taenia solium and Echinococcus sp., respectively. Parasitic diseases are useful models for in vivo studies of effector functions of T helper cell subsets 1 and 2, (called Th1 and Th2 on the basis of the pattern of cytokines they produce).
