Survey of anti-Toxoplasma gondii antibodies in wild mammals captured from Atlan...
Brito Junior,Pedro de Alcântara; Rocha,Josiane Moreira; Silva,Caroline Araújo da; Oliveira,Priscylla Marcelly Vilanova; Correia,Joelande EsquivelAbstract The objective of this study was to investigate the frequency of antibodies to Toxoplasma gondii present in wild mammals that were trap captured in forest fragments in the State of Bahia, northeastern Brazil. A total of 368 individuals (246 rodents, 104 marsupials and 18 bats) were captured using live catch traps. Serum samples were tested using the modified agglutination test, with a cut-off point at 1...
Unusual caudal vena cava thrombosis in a cow, secondary to Trueperella (Arcanob...
Motta,Rodrigo Garcia; Motta,Igor Garcia; Martinez,Antonio Campanha; Silva,Aristeu Vieira da; Paes,Antonio Carlos; Martins,Lorrayne Souza AraujoAbstract: The caudal vena cava thrombosis, or pulmonary thromboembolism, in cattle is correlated with lactic acidosis, caused by diets rich in grains and highly fermentable, associated or not to septic situations, used in feedlots of beef or high-producing dairy cattle. This paper reports an unusual caudal vena cava thrombosis in a cow, secondary to Trueperella (Arcanobacterium) pyogenes infection, resulting in...
Risk factors and presence of antibodies to Toxoplasma gondii in dogs from the c...
Silva,Rodrigo Costa da; Souza,Luiz Carlos de; Langoni,Hélio; Tanaka,Erika Maemi; Lima,Vanessa Yuri de; Silva,Aristeu Vieira daToxoplasmosis is caused by the obligate intracellular protozoan parasite Toxoplasma gondii and affects warm-blooded vertebrates, including pets and man. Dogs are epidemio-logically important since they act as sentinels for the infection in humans. The present study aimed to determine the presence of antibodies to T. gondii in 205 serum samples from dogs in Ubatuba, Sao Paulo state, Brazil, through indirect immu...
Effects of infection with Toxoplasma gondii oocysts on the intestinal wall and ...
Bonapaz,Rubia dos Santos; Hermes-Uliana,Catchia; Santos,Franciele do Nascimento; Silva,Aristeu Vieira da; Araújo,Eduardo José de AlmeidaThis paper aims to analyze the effects of the Toxoplasma gondii infection in the intestinal wall and myenteric plexus of chicken (Gallus gallus). Ten 36-day-old chickens were separated into two groups: control and experimental, orally inoculated with oocysts of the T. gondii strain M7741 genotype III. After 60 days the birds were submitted to euthanasia and had their duodenum removed. Part of the intestinal seg...
Efeitos da infecção crônica por Toxoplasma gondii sobre a parede intestinal de ...
Silva,Juliana Maria da; Silva,Aristeu Vieira da; Araújo,Eduardo José de Almeida; Sant'Ana,Débora de Mello GonçalesO objetivo deste trabalho foi analisar os efeitos da infecção causada pelo Toxoplasma gondii sobre a parede do duodeno de gatos. Foram utilizados seis gatos (Felis catus), com cerca de três meses de vida, distribuídos aleatoriamente em Grupo controle (G1; n = 3) e Grupo infectado (G2; n = 3). Os animais do G2 receberam, por via oral, 200 cistos teciduais da cepa ME49 (tipo II) do T. gondii. Após 40 dias, os ani...
Prevalence and risk factors for Toxoplasma gondii infection in certified and no...
Franciele Rossandra,Piassa; Araújo,Jacqueline Baptista de; Rosa,Ronaldo César da; Mattei,Rodrigo José; Silva,Rodrigo Costa da; Langoni,HelioToxoplasma gondii infection has been diagnosed in pigs all over the world. Economical losses are generally related to reproductive disorders. Toxoplasma infection is also a matter of public health because tissue cysts of the parasite may remain in pork and pork products, and become sources of human infection. The objective of this study was to evaluate the frequency and risk factors associated with Toxoplasma i...
Análise morfométrica da parede intestinal e dinâmica de mucinas secretadas no í...
Shiraishi,Celina Sayuri; Azevedo,Jorge Fernandes de; Silva,Aristeu Vieira da; Sant'Ana,Débora de Mello Gonçales; Araújo,Eduardo José de AlmeidaObjetivou-se analisar os efeitos da toxoplasmose sobre a morfometria da parede intestinal e a dinâmica de mucinas secretadas no íleo de frangos. Foram utilizados 16 frangos de corte machos (Gallus gallus) da linhagem Cobb, com 26 dias de idade. As aves foram divididas aleatoriamente em três grupos (G1, G2 e G3). O G1 não recebeu nenhum inóculo caracterizando o grupo controle, o G2 foi inoculado com cistos tecid...
Antineoplasic activity of Agaricus brasiliensis basidiocarps on different matur...
Mourão,Francielly; Linde,Giani Andrea; Messa,Valdeci; Cunha Júnior,Paulo Luiz da; Silva,Aristeu Vieira da; Eira,Augusto Ferreira daThe fungus Agaricus brasiliensis is a Basidiomycete studied because of its immunomodulation and/or antitumor substances. The objective of this study was to verify the Agaricus brasiliensis antineoplasic activity in vivo on different basidiocarp maturation phases on Sarcoma 180 cells implanted in mice. Sarcoma cells were implanted in mice and after seven days mice were divided in three groups. The first group wa...
Alterations of the myenteric plexus of the ileum and the descending colon cause...
Sugauara,Elaine Yae Yamashita; Sant'Ana,Débora de Mello Gonçales; Almeida,Elton Carlos de; Reis,Anderson Brunetti; Silva,Aristeu Vieira daAlterations caused by a genotype III strain of Toxoplasma gondii were assessed with respect to the number and the morphometry of the myenteric neurons in the terminal ileum and the descending colon. Eighteen rats were divided into four groups: Acute Control Group (ACG, n=4); Acute Experimental Group (AEG, n=4); Chronic Control Group (CCG, n=5) and Chronic Experimental Group (CEG, n=5). NaCl solution was adminis...
Toxoplasmose em ovinos e caprinos: estudo soroepidemiológico em duas regiões do...
Silva,Aristeu Vieira da; Cunha,Eva Laurice Pereira; Meireles,Luciana R.; Gottschalk,Susana; Mota,Rinaldo Aparecido; Langoni,HelioCom o objetivo de comparar variáveis epidemiológicas na toxoplasmose em ovinos e caprinos, amostras de soro de animais de propriedades localizadas em duas regiões do Estado de Pernambuco, Brasil, foram testadas pela reação de imunofluorescência indireta (RIFI) para detecção de anticorpos anti-Toxoplasma gondii. Dos 173 soros ovinos testados, em 35,3% foram encontrados resultados positivos, enquanto 40,4% dos 21...
