Aedes albopictus infection by the native bacterium Elizabethkingia anophelis in Southern Mexico.

Objective: To evaluate the presence of Elizabethkingia anophelis infection in Aedes albopictus wild populations of Southern Mexico.

Materials And Methods: Eight sites were selected to collect Aedes albopictus in the Soconusco region, Chiapas, females were analyzed to amplify the Gyrase B gene by PCR, the minimum infection rate of E. anopheliswas calculated and its species was determined by sequencing and phylogeny.

[Detection of Rickettsia typhi in Rhipicephalus sanguineus s.l. and Amblyomma mixtum in South of Mexico].

Objective: To determine the presence of Rickettsia typhi in Rhipicephalus sanguineus s.l. and Amblyomma mixtum in southern Mexico.

Infection of Aedes mosquitoes by native Wolbachia in urban cemeteries of Southern Mexico.

Objective: To evaluate the prevalence of Wolbachia infections in Aedes spp. field populations from cemeteries of Southern Mexico.

Materials And Methods: Six cemeteries were selected to be sampled in the central part of the Soconusco region, Chiapas.

Protein phosphorylation during Plasmodium berghei gametogenesis.

Plasmodium gametogenesis within the mosquito midgut is a complex differentiation process involving signaling mediated by phosphorylation, which modulate metabolic routes and protein synthesis required to complete this development. However, the mechanisms leading to gametogenesis activation are poorly understood. We analyzed protein phosphorylation during Plasmodium berghei gametogenesis in vitro in serum-free medium using bidimensional electrophoresis (2-DE) combined with immunoblotting (IB) and antibodies specific to phosphorylated serine, threonine and tyrosine.

[Malaria's seroepidemiology in a group of migrants in transit (Chiapas, 2008)].

Objective: To know the prevalence of malaria and the factors associated with the infection in migrants in the southern border of Mexico, during 2008.

Materials And Methods: In 706 migrants, active malaria infection was investigated using a rapid diagnostic test and PCR and past infection using serology. A questionnaire was applied to investigate the conditions associated to infection.
