ABSTRACT

A doença da arranhadura do gato é uma zoonose causada por bactérias do gênero Bartonella. O gato atua como reservatório de Bartonella henselae e a transmissão ao humano ocorre através da arranhadura ou mordedura. A esporotricose, causada por fungos do complexo Sporothrix, é transmitida aos humanos através da implantação traumática deste microrganismo no tecido subcutâneo. Os gatos com esporotricose apresentam lesões cutâneas ulceradas com elevada carga parasitária e têm importante papel na transmissão. Nos últimos 14 anos foram diagnosticados mais de 3.000 casos de esporotricose felina no IPEC/FIOCRUZ. Com o objetivo de estudar a soroprevalência de infecção por Bartonella spp. em gatos com esporotricose, 112 amostras de soro foram submetidas ao teste de imunofluorescência indireta utilizando o kit B. henselae IFA IgG (Bion®, USA). Além disso, foi realizada a pesquisa de anticorpos anti-vírus da leucemia felina (FeLV) e antígenos do vírus da imunodeficiência felina (FIV) utilizando kit comercial Snap Combo FIV-FeLV (Idexx®, USA). Um grupo composto por 77 amostras de soro de gatos sem lesões cutâneas aparentes também foi incluído no estudo. No grupo de gatos com esporotricose, 93 eram machos, a idade mediana foi 22 meses e oito (7,1 por cento) foram positivos para FIV e 15 (13,4 por cento) para FeLVNo grupo sem lesões cutâneas, 36 eram machos, a idade mediana foi 48 meses, e dez (13,0 por cento) gatos foram positivos para FIV e oito (10,4 por cento) para FeLV. Dos 112 gatos com esporotricose e dos 77 sem leões cutâneas, 72 (64,3 por cento) e 35 (45,5 por cento), respectivamente, foram reativos ao teste de imunofluorescência para Bartonella spp. Não houve associação entre as variáveis faixa etária, sexo, status sorológico para FIV/FeLV e a presença de anticorpos anti-Bartonella spp. Os resultados obtidos sugerem que a população de gatos com esporotricose deste estudo pode ser considerada uma potencial fonte de infecção humana também para Bartonella spp...


Cat scratch disease is a zoonosis caused by species of genus Bartonella. Cats are the mainreservoir of Bartonella henselae. Transmission of these bacteria to humans occurs throughbites or scratches of infected cats. Sporotrichosis, caused by fungus of Sporothrix complex,is transmitted by traumatic inoculation of soil, plants and organic matter contaminated withthe fungus. Cats are important in zoonotic transmission because of the large amount ofyeast cells in the lesions. In the last 14 years were diagnosed more than 3.000 cases offeline sporotrichosis in IPEC/FIOCRUZ. The main objective of this study was toinvestigate the prevalence of infection by Bartonella spp. in cats with sporotrichosis. Serumsamples from 112 domestic cats were analyzed by indirect immunofluorescence test assay(IFA) using the commercial kit B. henselae IFA IgG (Bion®, USA). In addition, it wasdetected the presence of antibodies to feline leukemia vírus (FeLV) and antigens of felineimmunodeficiency virus (FIV) using the commercial kit Snap Combo FIV-FeLV (Idexx®,USA). One group of 77 serum samples from cats with no apparent skin lesions was alsoincluded in the study. In the group of animals with sporotrichosis, 93 were males, medianage was 22 months, and eight (7.1 percent) were positive for FIV, 15 (13.4 percent) were positive forFeLV. In the group of animals without skin lesions 36 were males, median age was 48months, and ten (13.0 percent) were positive for FIV, eight (10.4 percent) were positive for FeLV. Ofthe 112 cats with sporotrichosis and 77 cats without skin lesions, 72 (64.3 percent) e 35 (45.5 percent),respectively, were reactive to IFA. There was no association between age, sex, FIV/FeLVand the presence of antibodies to Bartonella spp. The results suggest that the studypopulation can be considered a potential source of human infection by both zoonosis...

ABSTRACT

The human bartonelloses are a group of diseases with a rapidly increasing clinical spectrum. Well known manifestations such as Carrion's disease, trench fever, cat-scratch disease, and bacillary angiomatosis are examples of Bartonella spp. infection. Along with these diseases, recurrent bacteremia, endocarditis, septicemia, erythema nodosum, erythema multiforme, trombocytopenic purpura and other syndromes have been reported having been caused by bacteria of this genus. The infectious process and the pathogenesis of these microorganisms are poorly understood. The bartonelloses may have a benign and self-limited evolution in a host, or a potentially fatal one. These bacteria can provoke a granulomatous or an angioproliferative histopathologic response. As these diseases are not yet well defined, we have reviewed the four main human bartonelloses and have examined unclear points about these emergent diseases

ABSTRACT

La angiomatosis bacilar es una nueva entidad, descrita en sujetos inmunodeprimidos, debida a un agente bacteriáceo oportunista de la familia de las Rickettsias, denominado Rochalimaea henselae que tiene estrecha relación con los agentes causantes de la fiebre de las trincheras, de la enfermedad por rasguño de gato y la fiebre de Oroya y verruga peruana. Histopatológicamente la angiomatosis bacilar se caracteriza por lesiones compuestas por proliferación capilar, infiltrado celular a base de polimorfonucleares y un material amorfo granular. Clínicamente la afección se traduce por síntomas generales; manifestaciones cutáneas entre las que destacan las nodulares y compromiso visceral sistémico. El diagnóstico se basa en la existencia de inmunodepresión, biopsia de piel y tinción de Warthin-Starry que permite demostrar el agente causal. La eritromicina administrada entre 6 semanas y 3 meses es el tratamiento de elección que permite la regresión total de las lesiones, las que suelen recurrir.
