Babesia/Babesiosis

La babesiosis es una infección causada por un protozoo que pertenece al género Babesia. La Babesia más común que se observa en Estados Unidos es B. microti, que se transmite por la garrapata Ixodes. Los protozoos crecen y se replican dentro de los eritrocitos del húesped. La lisis de los eritrocitos y la respuesta inmunitaria del organismo dan lugar a síntomas clínicos. Los pacientes generalmente presentan una enfermedad similar a la gripe e ictericia. En casos severos, puede ocurrir daño a los órganos. El diagnóstico se confirma por la presencia visual de parásitos dentro de los eritrocitos, que a menudo se observa en una configuración de "Cruz de Malta".

Características Generales de Babesia

Características básicas de Babesia Babesia Babesiosis is an infection caused by a protozoa belonging to the genus, Babesia. The most common Babesia seen in the United States is B. microti, which is transmitted by the Ixodes tick. The protozoa thrive and replicate within host erythrocytes.

  • Ehrlichiosis Ehrlichiosis Ehrlichiosis is a tick-borne bacterial infection. The most common causative species include Ehrlichia chaffeensis, which infect and multiply within monocytes. The clinical presentation can vary widely, but often includes fever, malaise, headache, myalgia, and arthralgias. Ehrlichiosis and Anaplasmosis y anaplasmosis Anaplasmosis Anaplasmosis is a tick-borne bacterial infection. The most common causative species include Anaplasma phagocytophilum, which infect and multiply within granulocytes. The clinical presentation can vary widely, but often includes fever, malaise, headache, myalgia, and arthralgias. Ehrlichiosis and Anaplasmosis: infecciones transmitidas por garrapatas causadas por Ehrlichia chaffeensis Ehrlichia chaffeensis A species of gram-negative bacteria that is the causative agent of human ehrlichiosis. This organism was first discovered at fort chaffee, arkansas, when blood samples from suspected human ehrlichiosis patients were studied. Ehrlichiosis and Anaplasmosis y Anaplasmosis Anaplasmosis Anaplasmosis is a tick-borne bacterial infection.

La coagulación intravascular diseminada, la falla multiorgánica y el coma Coma Coma is defined as a deep state of unarousable unresponsiveness, characterized by a score of 3 points on the GCS. A comatose state can be caused by a multitude of conditions, making the precise epidemiology and prognosis of coma difficult to determine. Coma también pueden ocurrir con la enfermedad grave. El diagnóstico se realiza mediante PCR PCR Polymerase chain reaction (PCR) is a technique that amplifies DNA fragments exponentially for analysis. The process is highly specific, allowing for the targeting of specific genomic sequences, even with minuscule sample amounts. The PCR cycles multiple times through 3 phases: denaturation of the template DNA, annealing of a specific primer to the individual DNA strands, and synthesis/elongation of new DNA molecules. Polymerase Chain Reaction (PCR). El tratamiento de ambas enfermedades es con doxiciclina.
