“…Proteus is mainly used as diagnostic test for Rickettsia because a cross-reaction exists. Rickettsia has been reported in raccoons from the US and Japan (Alexander et al 1972, Baba et al 2013 and in humans from the northern and southeastern regions of Mexico (Zavala-Castro et al 2006). Rickettsial infections were associated with tick bites, but in the present study antibodies against Proteus were not detected.…”

Rickettsioses in Latin America, Caribbean, Spain and Portugal

Data on genus and infectious by Rickettsia were retrospectively compiled from the critical review literature regarding all countries in Latin America, Caribbean islands, Portugal and Spain. We considered all Rickettsia records reported for human and/or animal hosts, and/or invertebrate hosts considered being the vector. In a few cases, when no direct detection of a given Rickettsia group or species was available for a given country, the serologic method was considered. A total of 13 Rickettsia species have been recorded in Latin America and the Caribbean. The species with the largest number of country confirmed records were Rickettsia felis (9 countries), R. prowazekii (7 countries), R. typhi (6 countries), R. rickettsii (6 countries), R. amblyommii (5 countries), and R. parkeri (4 countries). The rickettsial records for the Caribbean islands (West Indies) were grouped in only one geographical area. Both R. bellii, R. akari, and Candidatus ‘R. andeane’ have been recorded in only 2 countries each, whereas R. massiliae, R. rhipicephali, R.monteiroi, and R. africae have each been recorded in a single country (in this case, R. africae has been recorded in nine Caribbean Islands). For El Salvador, Honduras, and Nicaragua, no specific Rickettsia has been reported so far, but there have been serological evidence of human or/and animal infection. The following countries remain without any rickettsial records: Belize, Venezuela, Guyana, Surinam, and Paraguay. In addition, except for a few islands, many Caribbean islands remain without records. A total of 12 Rickettsia species have been reported in Spain and Portugal: R. conorii, R. helvetica, R. monacensis, R. felis, R. slovaca, R. raoultii, R. sibirica, R. aeschlimannii, R. rioja, R. massiliae, R. typhi, and R. prowazekii. Amongst these Rickettsia species reported in Spain and Portugal, only R. prowazekii, R. typhi, R. felis, and R. massiliae have also been reported in Latin America. This study summarizes the current state of art on the rickettsial distribution in Latin America, Caribbean, Spain and Portugal. The data obtained allow a better understanding on rickettsial epidemiology and distribution of vector ecology.Key words: Acari, epidemiology, rocky mountain spotted fever, vector control.

“…The fi rst fatal R. rickettsii infection in southwest Mexico was diagnosed recently [22]. However, despite reports in Argentina and Peru, the incidence and distribution of RMSF in Latin America are undoubtedly underestimated and await the collaborative efforts of physicians, rickettsiologists, entomologists, and epidemiologists to characterize the magnitude and public health impact of such infections in these regions [17,[23][24][25].…”

During most of the 20th century, Rickettsia rickettsii, the agent of Rocky Mountain spotted fever, was considered the only tick-borne rickettsia associated with human diseases in the Americas. This dogma suggested that the other characterized and noncharacterized rickettsiae isolated from ticks were not pathogenic to humans. This concept has been modified extensively in the past 10 years with the identification of at least three additional rickettsial species that cause human tick-borne rickettsioses and that are prevalent in the Americas, including Rickettsia parkeri, Rickettsia massiliae, and Rickettsia africae. Moreover, the genetic variability of R. rickettsii and the milder forms of Rocky Mountain spotted fever reactivate the hypothesis that some circulating genotypes of R. rickettsii may be more virulent than others and may explain the wide variations in fatality rates of the disease.
