[Septic shock by Vibrio vulnificus at the coast Gulf of Mexico].

Vibrio vulnificus is a Gram-negative bacterium which is found in marine environments and where there is a partly enclosed coastal body of water with one or more rivers or streams flowing into it, and with a free connection to the open sea. The infection by these bacteria can cause primary septicemia by two mechanisms: upon consuming crustaceans, mollusks and some fish (filtering shellfish) raw or barely cooked or by an open injury in contact with seawater. The patients with infections of the primary injury by Vibrio vulnificus developed contaminated painful cellulitis that progresses quickly as well as a marked local inflammation with signs of hemorrhaging.

[Hysteroscopy findings in patients with postmenopausal genital bleeding].

Objective: To describe morphological and histological findings in postmenopausal patients with abnormal uterine bleeding.

Patients And Methods: An open, descriptive, observational, retrospective and cross sectional study was done at Clinica de Histeroscopia at Hospital Dr. Manuel Gea Gonzalez, in Mexico City.

Epidemiologic and ultrasonographic study of echinococcosis in a community in the state of Mexico.

No epidemiologic study for cystic echinococcosis in México has yet been described. The objective of this work was to determine the prevalence and distribution of human echinococcosis in a community of the state of México and its probable risk factors. A cross-sectional study was performed; household census was used to randomly select houses.

Lack of postmortem digestion of tapeworms in Golden hamsters experimentally infected with Taenia solium.

Taenia solium causes human neurocysticercosis, a public health problem in Mexico and other developing countries. Surprisingly, tapeworm carriers are very rarely found and in necropsy studies practically no tapeworms have been reported. In this paper we analyze the possibility that, after the death of the host, tapeworms could easily be destroyed in the intestine.

Laboratory animal models for human Taenia solium.

Human beings are the only hosts of adult Taenia solium; thus, many aspects of the host-parasite relationship are unknown. The development of successful experimental models of taeniasis allows in-depth investigations of the host-parasite relationship. We established experimental models in hamsters, gerbils and chinchillas.

Echinococcus granulosus cattle strain identification in an autochthonous case of cystic echinococcosis in central Mexico.

Echinococcosis is a frequent hepatic parasitic disease in several countries but it is practically absent in Mexico. A cattle strain of Echinococcus granulosus was identified by RAPD, PCR-RFLP and mitochondrial CO1 gene analysis in an autochthonous case. The parasite was obtained after a laparoscopic excision of a liver cyst from a patient that was symptomatic for 6 years but mis-diagnosed before hospitalization.

[Identification and integral management of a case of autochthonous hydatidosis in Mexico].

Objective: To describe a case of hydatid disease in Mexico.

Background: Liver hydatid disease is the most frequent hepatic parasitic disease in developed countries and is considered practically absent in Mexico.

Methods: In this paper we report identification, clinical management, and epidemiologic parasitologic, and molecular biological studies of an autochthonous case of hydatid disease in Mexico.
