Scrub typhus is a potentially fatal rickettsial infection
. Usually, it presents as acute febrile illness, and multiorgan involvement can be seen.
in the wildlife and human communities is rapidly spreading in tropical regions (Parola, et al.
Initially, all the tick samples were screened for rickettsial infection
through testing them individually with a PCR protocol using the primers CS-78 (forward) and CS-323 (reverse) targeting a 401-bp fragment of the rickettsial citrate synthase gene (gltA) (LABRUNA et al., 2004b), which is relatively conserved in all Rickettsia species (RAOULT & ROUX, 1997).
This would help us know if the lower rate of rickettsial infection
in the rural population of Yucatan could be due to a lower presence of Rickettsia species in rural areas or to practices and habits of the rural population that inhibit the life cycle of Rickettsia sp.
Serum from a patient previously proven to have a rickettsial infection
with high antibody titres in IFA (IgG 1 : 128) was used as the positive control.
in Amblyomma nodosum ticks (Acari: Ixodidae) from Brazil.
Doxycycline is the recommended treatment for all patients with a tickborne rickettsial infection
, including R.
Sterile, round glass cover slips were placed in some of the wells for evaluation of the rickettsial infection
. Duplicate wells were used for each treatment in a given experiment.
in Dermacentor variabilis (Acari: Ixodidae) inhibits transovarial transmission of a second Rickettsia.
Noncardiogenic pulmonary edema results from rickettsial infection
of the pulmonary microcirculation, vascular injury, and consequently increased vascular permeability.
Here, we report a case of PF in a child secondary to rickettsial infection
, who was managed efficiently with timely intervention.
A serious strategy to update the curriculum to include rickettsial infection
as a health problem in Mexico and possibly other countries.
