“…Our results do not support the concept of risk area for R. typhi infection in this Brazilian region. C. burnetii infection has been reported in serosurveys of more than 30 years ago (Ribeiro-Neto et al 1964, Riemann et al 1974, 1975 but since then, no information of such infection has been available from Brazil. Q fever has been reported Southern (Moreira et al 1989) and Northern Brazil (Tran et al 2002) but for inexplicable reasons little attention has been paid to it, not withstanding the fact that it is supposed to be a worldwide zoonosis presents everywhere (Casolin 1999, CDC 2004.…”

Rickettsial diseases except those belonging to spotted fever group rickettsioses are poorly studied in South America particularly in Brazil where few epidemiological reports have been published. We describe a serosurvey for Rickettsia rickettsii, R. typhi, Coxiella burnetii, Bartonella henselae, B. quintana, and Ehrlichia chaffeensis in 437 healthy people from a Brazilian rural community. The serum samples were tested by indirected micro-immunoflourescence technique and a cutoff titer of 1:64 was used. The seroprevalence rates for R. rickettsii, R. typhi, C. burnetii, B. henselae, B. quintana, and E. chaffeensis were respectively 1.6% (7 samples (WHO 1993, Rozental et al. 2002, Walker 2004a. Until recently the rickettsiales order comprised the genus Rickettsia, Coxiella, Bartonella, Orientia, Anaplasma, and Ehrlichia (Raoult & Roux 1997) and despite of the resulting withdraw of some of them from this order especially due to 16S rRNA studies, they all can be functionally considered rickettsial agents (Raoult & Roux 1997, Walker 2004b.Most of the available publications of Brazilian rickettsial infections have focused on spotted fever group rickettsioses especially R. rickettsii infections (Lemos et al. 1994, Del Guercio et al. 1997, Rozental et al. 2002, Galvão et al. 2003. This issue has been extensively reviewed recently by Galvão (2004). Despite of the fact that new rickettsial agents have been described more recently in Brazil (Oliveira et al. 2002), the whole scenario of rickettsial infections still have black holes reinforcing the nonexistence concept for such infections in this part of the world.The Piau county as well as the southern part of the state of Minas Gerais had been considered free of any rickettsial diseases until 1994 when a family cluster of Brazilian spotted fever was reported (Hallack et al. 1996). Thereafter reports of Brazilian spotted fever have been Given these above mentioned facts and the much-appropriated local ecologic conditions for rickettsial infections we choose this particular region for studying the seroprevalence rates for R. typhi, C. burnetii, B. henselae, B. quintana, and E. chaffeensis as well as R. rickettsii infections among healthy individuals from a Brazilian rural community. MATERIALS AND METHODSSerum samples from 437 healthy individuals of both sexes aged from 5 to 92 years old, living in the county of Piau, state of Minas Gerais, Brazil were tested for the presence of R. rickettsii, R. typhi, C. burnetii phase I and phase II, B. henselae, B. quintana, and E. chaffeensis IgG and IgM antibodies. This county (Fig. 1), located at latitude 21º30'34''S and longitude 43º19'25''W, has 3008 inhabitants, 58% of them living in the small village and the remainders scattered throughout the county, mostly in small farms. The local economics is somehow linked to cattle farming and the entire population has continuous contact with several domestic animals. Tick attack history is widespread affecting roughly 100% of the population. From March to April 2001, health officials offe...

Resumen: Los Médicos Veterinarios están expuestos a peligros físicos, biológicos, químicos y radiaciones. Los objetivos de este trabajo consisten en revisar sus accidentes laborales (AL) y enfermedades profesionales (EP), factores y percepciones de riesgo, uso y disposición de elementos de protección personal (EPP) en América Latina y el Caribe. La frecuencia de profesionales que sufren accidentes, in labore, es muy alta; con la consecuente pérdida de días laborales. Los AL varían según la especie animal. Los más frecuentes son: mordeduras, rasguños, atropellamientos y aprisionamientos por animales, así como heridas por elementos punzocortantes. En clínica de grandes animales, la zoonosis más diagnosticada es la brucelosis; en la práctica con pequeñas especies, dermatofitosis y sarna. Entre las EP de origen ergonómico, se destacan las afecciones músculo esqueléticas (columna y articulaciones). La atención clínica no se percibe como de alto riesgo; aunque la mayor parte de los AL ocurre en dichas instancias. La frecuencia de uso de EPP varía en las distintas actividades profesionales y poblaciones relevadas. Los guantes son los más utilizados; mientras que la falta de uso de protectores oculares o faciales es muy evidente. No hay asociaciones entre percepción del riesgo y uso de EPP. En general, ambas son más frecuentes entre las mujeres y los jóvenes. La disposición final de insumos descartables, muchas veces, es inapropiada. La percepción de riesgos y la adopción de buenas prácticas, in itinere, es mayor en rutas principales que en caminos rurales; sin embargo, los AL son más frecuentes en estos últimos. Los AL y las EP no deben ser asumidos como algo natural, de ocurrencia corriente, que no requiere acción alguna. Es necesario cambiar conductas y actitudes en el ejercicio de la profesión, mejorar las condiciones de trabajo, concientizar las nuevas generaciones de profesionales y cumplir con el deber social de ser agentes de Salud Pública.Palabras clave: salud ocupacional, práctica veterinaria, factores de riesgo, percepción del riesgo, elementos de protección personal.Abstract: Veterinarians are exposed to physical, biological, chemical and radiation hazards. The objective of this study was to review work accidents (WA) and diseases (WD), risk factors and perceptions, use and disposal of personal protective equipment (PPE) in Veterinary Medicine in Latin America and the Caribbean. Frequency of work accidents for veterinarians is very high, with the resulting loss of working days. WAs vary according to animal species. The most frequent WAs were bites, scratches, running over/imprisonment by animals and wounds caused by sharp objects. The most frequently diagnosed zoonosis in large animal clinics was brucellosis, while dermatophytosis and scabies in small animal practices. Injuries of an ergonomic nature include musculoskeletal injuries (spine and joints). Clinical practice was not perceived as a high-risk activity, although most WAs occurred in those instances. Frequency of use of PPE varied depending on the di...

Abstract. Coxiella burnetii, the causative agent of Q fever, is present worldwide. Recent studies have shown that this bacterium is an emerging pathogen in French Guiana and has a high prevalence (24% of community-acquired pneumonia). In this review, we focus on the peculiar epidemiology of Q fever in French Guiana. We place it in the context of the epidemiology of the disease in the surrounding countries of South America. We also review the clinical features of Q fever in this region, which has severe initial presentation but low mortality rates. These characteristics seem to be linked to a unique genotype (genotype 17). Finally, we discuss the issue of the animal reservoir of C. burnetii in French Guiana, which is still unknown. Further studies are necessary to identify this reservoir. Identification of this reservoir will improve the understanding of the Q fever epidemic in French Guiana and will provide new tools to control this public health problem.
