Consensus for the diagnosis, prognosis and treatment of canine mammary tumors

Brazilian Journal of Veterinary Pathology (2011)

Geovanni Dantas Cassali Gleidice Eunice Lavalle Ênio Ferreira Alessandra Estrela‐Lima Andrígo Barboza De Nardi

Mammary neoplasms are described as the third most common type of feline tumor, after haematopoietic and skin tumors, and present a challenge for clinicians because the prognosis for feline mammary tumors ranges from guarded to poor. Thus, it is necessary to define new therapeutic approaches and establish more in-depth knowledge about this disease in felines. The main aspects of the diagnosis, prognosis and treatment of feline mammary neoplasia were discussed, aiming to standardize the criteria and to serve as a guide for pathologists and veterinary clinicians.

B-mode ultrasonography and gray scale histogram for evaluation of the nuchal ligament in Quarter horse

Pesquisa Veterinária Brasileira (2019)

Wildemberto A. Santos Michel de Campos Vettorato Jéssica Leite Fogaça N.M.G. Mazzante Fernanda Gabriela de Oliveira

ABSTRACT: The gray scale histogram (GSH) makes it possible to measure the amount and distribution of gray shade frequencies, providing quantitative information on both echogenicity and echotexture of tissues. There is a need to diminish the subjectivity of the ultrasound images of the nuchal ligament (NL). This work proposes to evaluate the NL by ultrasound B-mode GSH images in different ages of Quarter horses. It used 15 healthy Quarter horses, which were classified by age into three different groups: “baby” (1), “sobreano” (2) and “adult” (3). The animals were submitted to chemical restraint for the ultrasound examination. Subsequently, the GSH tool was used in each image for statistical analysis. There was a significant difference between Mean and Mode between groups. Group 1 differed significantly when compared to Group 2 and 3. Group 2 presented superior echogenicity to Group 1 and 3. The height of the NL did not vary considerably between groups. GSH indicated that the echogenicity of NL in Quarter horses varies with age.

Eosinophilic inflammation in lymph nodes of dogs with visceral leishmaniasis

Parasite Immunology (2018)

Sidnei Ferro Costa Gabriel Franco Trivellato Gabriela Torres Rebech Marilene Oliveira dos Santos Maciel Larissa Martins Melo

Eosinophils are traditionally associated with the immune response against helminth parasites. However, several studies have demonstrated that these cells have a role regarding protective immunity in leishmaniasis. Here, we examined the relationship between the presence of eosinophils and parasite load in biopsy samples from dogs, obtained through fine needle puncture and aspiration of lymph nodes. Histological slides containing biopsy material from lymph nodes of dogs with canine visceral leishmaniasis and healthy dogs were used to obtain baseline eosinophil counts. Subsequently, scrapings were taken from slides for DNA extraction and determination of parasite load, using real-time PCR (qRT-PCR). Additionally, production of nitric oxide (NO) and reactive oxygen species (ROS) levels by eosinophils in the peripheral blood of dogs with canine visceral leishmaniasis and healthy dogs was measured. The eosinophil percentage were higher in lymph nodes of infected group, and the parasite load showed a significant negative correlation with the eosinophil count. The production of NO and ROS by eosinophils in the peripheral blood was higher in the dogs with canine visceral leishmaniasis. All the results together suggest that eosinophils may participate in antileishmanial immunity in canine visceral leishmaniasis.

Detection of Turkey Astrovirus in Young Poults Affected with Poult Enteritis Complex in Brazil

Journal of Veterinary Medical Science (2008)

S.E.L. da Silva Ana Maria Bonetti A. Petrocelli Heitor F. Ferrari Maria Cecília Rui Luvizotto

Reverse transcription polymerase chain reaction (RT-PCR) of turkey astrovirus (TAstV) capsid and polymerase genes was applied to the bursa of Fabricius (BF), thymus (TH), spleen (SP) and cloacal swabs (CS) of young poults with "Poult enteritis complex" (PEC). The histological lesions included atrophy, lymphoid depletion, cellular infiltration and necrosis of the BF, TH and SP, respectively. The RT-PCR reactions were positive for the polymerase gene of TAstV-2 in all 100 CSs, 7 out of 10 of BFs and 10 out of 20 THs and SPs, respectively. Five out of 10 THs and SPs samples, considered to be negative by RT-PCR, were positive when specific primers designed for the TAstV-2 capsid gene were applied. This is the first description of turkey astrovirus infection presenting PEC in Latin America.

Congenital Toxoplasmosis in Chronically Infected and Subsequently Challenged Ewes

PLoS ONE (2016)

Thaís Rabelo dos Santos Gabriela Faria Bruna Martins Guerreiro Nathália Helena Pereira da Silva Dal Pietro Welber Daniel Zanetti Lopes

This experiment studied congenital transmission in sheep experimentally infected with oocysts of Toxoplasma gondii and reinfected at one of three stages of pregnancy. Twenty ewes were experimentally infected with T. gondii strain ME49 (day 0). After the T. gondii infection became chronic (IFAT≤512), the ewes were allocated with rams for coverage. After the diagnosis of pregnancy, these ewes were allocated into four experimental groups (n = 5): I-reinfected with T. gondii on the 40th day of gestation (DG); II-reinfected on DG 80; III-reinfected on DG 120; and IV-saline solution on DG 120 (not reinfected). Five ewes (IFAT<64) were kept as negative controls (uninfected, group V), therefore in groups I-III were infected prior to pregnancy and re-infected during pregnancy, group IV was only infected prior to pregnancy, and group V was not infected. Parasitism by T. gondii was investigated (histopathology, immunohistochemistry, mouse bioassay and PCR) in mothers and lambs tissue. All ewes produced lambs serologically positive for T. gondii. The results of the mouse bioassay, immunohistochemistry and PCR assays revealed the presence of T. gondii in all 20 sheep and their lambs. The congenital transmission of T. gondii was associated with fetal loss and abnormalities in persistently infected sheep and in ewes infected and subsequently reinfected by this protozoan. Therefore, congenital T. gondii infection was common when ewes were chronically infected prior to pregnancy, with or without reinfection during at various stages of gestation.

RESUMO As leishmanioses tegumentar (LTA) e visceral americana (LVA), em caninos e humanos, encontram-se em crescente expansao no Estado de Sao Paulo. Para a vigilância epidemiologica dessas endemias, e fundamental o conhecimento da distribuicao e ecologia das diferentes especies vetoras de flebotomineos e, para a LVA, o conhecimento da prevalencia da enfermidade no cao, seu principal reservatorio. Objetivou-se assim verificar a abundância e distribuicao de flebotomineos e pesquisar a presenca de anticorpos anti- Leishmania em uma amostra da populacao canina do municipio de Monte Mor, SP, visando identificar possiveis caes infectados. Nas capturas de flebotomineos utilizaram-se armadilhas automaticas luminosas do tipo CDC em 16 pontos diferentes do municipio, no periodo noturno (18h as 8h), de abril de 2006 a abril de 2008, com posterior processamento e identificacao dos especimes. Um total de 319 amostras de soro canino foi processado pelas tecnicas de ELISA e RIFI com utilizacao de Leishmania major como antigeno. Em 14 dos 16 locais avaliados encontraram-se flebotomineos, num total de 86 exemplares, com identificacao de sete especies: Nyssomyia neivai , N. whitmani , Pintomyia monticola , P. pessoai , Migonemyia migonei , Brumptomyia brumpti e Evandromyia termitophila . N. neivai , considerada a principal especie vetora de LTA no Estado de Sao Paulo, mostrou-se a mais abundante com 48,84% do total capturado e presente em dez dos 14 locais com flebotomineos. Todas as 319 amostras caninas apresentaram-se negativas para anticorpos anti- Leishmania . A abundância de N. neivai, aliada a presenca de especies vetoras secundarias como N. whitmani , M. migonei e P. pessoai , ilustra risco de transmissao da LTA no municipio. A ausencia de Lutzomyia longipalpis e de caes reagentes para leishmaniose, indicam ate o momento ausencia da LVA canina, com baixo risco de estabelecimento desta doenca no municipio. Ressalta-se, porem, a necessidade da manutencao das acoes de vigilância epidemiologica, ampliando-se os pontos de captura de flebotomineos, bem como se mantendo a avaliacao clinica e laboratorial periodica da populacao canina, visando-se assim impedir a introducao e estabelecimento desta grave enfermidade no municipio.

LEISHMANIASIS EPIDEMIOLOGICAL SURVEILLANCE IN MONTE MOR CITY, sao PAULO STATE, BRAZIL ABSTRACT Cutaneous (LTA) and Visceral (LVA) American Leishmaniasis incidences are increasing in human and canine, especially LVA, which is expanding its range through Sao Paulo State. Distribution and ecology knowledge of different sand fly species, and in case of LVA, the prevalence of Leishmania infection in dogs, its main reservoir, are essential for leishmaniasis epidemiology vigilance. Considering this, it was studied sand flies abundance and distribution, and also the presence of anti- Leishmania IgG antibodies in dogs, from different areas of Monte Mor county, Sao Paulo State. Sand flies were trapped in urban and rural areas between April 2006 and April 2008. CDC automatic light traps were used from 18h to 8h, during 16 nights. 319 canine sera samples were processed by ELISA and RIFI techniques, using Leishmania major as antigen. 86 phlebotomines were found in 14 out of 16 evaluated places, resulting in seven different sand fly species identified: Nyssomyia neivai, Pintomyia monticola, P. pessoai, N. whitmani, Migonemyia migonei, Brumptomyia brumpti and Evandromyia termitophila . N. neivai , pointed out as the main LTA vector in Sao Paulo State, was the most abundant species (48.84% of the total captured), being found in 10 out of 14 places where sand flies were captured. All 319 canine sera were negative in serological tests. The finding of N. neivai and also the presence of secondary vector species as N. whitmani , M. migonei and P. pessoai , indicates the risk of LTA transmission in different places of Monte Mor county. The absence of Lutzomyia longipalpis sand fly species and also the absence of dogs with anti- Leishmania IgG antibodies indicates, in the moment no occurrence of canine LVA in the city, with low risk of establishment of this disease in the studied area. Due to the high importance of leishmaniasis in the public health context, epidemiological vigilance actions must be continuously performed. Key words: Leishmania, sandfly, epidemiology, Campinas metropolitan region, serology, canine leishmaniasis. VIGILANCIA EPIDEMIOLOGICA DE LAS LEISHMANIOSIS EN el municipio DE MONTE MOR, ESTADO DE SAO PAULO, BRASIL RESUMEN La incidencia de las leishmaniosis tegumentaria (LTA) y visceral americanas (LVA) en hospederos caninos y humanos se encuentra en creciente expansion en el estado de Sao Paulo, Brasil. Para la vigilancia epidemiologica de tales endemias, es fundamental el conocimiento de la predominancia y ecologia de las diferentes especies vectores de flebotomos y, para la LVA, el conocimiento de la prevalencia de la enfermedad en el perro, su principal reservorio. Se busco verifica la abundancia y distribucion de flebotomos y pesquisar la presencia de anticuerpos IgG anti- Leishmania en sueros de una muestra de la poblacion de perros, para el eventual encuentro de perros infectados, en la ciudad de Monte Mor, estado de Sao Paulo. Para las capturas de los insectos se utilizaron trampas automaticas luminosas del tipo CDC, en 16 puntos diferentes de la ciudad, en el periodo nocturno (18h a las 8h), desde abril de 2006 hasta abril de 2008, con posterior procesamiento e identificacion de los flebotomos hacia el nivel de especie. El total de 319 muestras de sueros fueron procesados por las tecnicas de ELISA y RIFI con utilizacion de Leishmania major como antigeno. En 14 de 16 locales evaluados se encontro flebotomos, totalizando 86 ejemplares, con identificacion de siete especies: Nyssomyia neivai , Pintomyia monticola , P. pessoai , N. whitmani , Migonemyia migonei , Brumptomyia brumpti y Evandromyia termitophila . N. neivai , considerada el principal vector de la LTA en el estado de Sao Paulo, fue la especie mas abundante con 48,84% del total capturado y presente en 10 de 14 locales con flebotomos. Todas las 318 muestras de sueros caninos se presentaron negativas para anticuerpos IgG anti- Leishmania . La abundancia de N. neivai junto a la presencia de especies vectores secundarios de leishmaniosis como N. whitmani , M. migonei y P. pessoai , ensena el riesgo de transmision de la LTA en el municipio. La ausencia de Lutzomyia longipalpis y de perros portadores de anticuerpos anti- Leishmania , indican hasta el presente momento la ausencia de la LVA canina, con bajo riesgo de establecimiento de esta enfermedad en el municipio. Todavia, las acciones de vigilancia epidemiologica deben de ser continuamente adoptadas, siendo de extrema importancia desde el punto de vista de la salud publica regional.
