Human toxoplasmosis, a protozoonosis caused by Toxoplasma gondii, has been described as worldwide foodborne disease with important public health impact. Despite infection reportedly varied due to differences in alimentary, cultural and hygienic habits geographic region, social vulnerability influence on toxoplasmosis distribution remains be fully established. Accordingly, the present study aimed assess T. gondii seroprevalence factors associated for households of Ivaiporã, southern Brazil,...
Canine monocytic ehrlichiosis caused primarily by Ehrlichia canis and canine thrombocytic anaplasmosis induced Anaplasma platys are important emerging zoonotic tick-borne diseases of dogs. There is evidence that these pathogens can also affect humans. This study evaluated the presence E. A. in blood samples collected from 256 domiciled dogs municipality Jataizinho, located north region State Parana, Brazil, PCR assay. The occurrence was 16.4% (42/256) 19.4% (49/256), respectively; while...
Leptospirosis, toxoplasmosis and brucellosis are diseases with worldwide distribution. Among stray dogs, these zoonoses facilitated by direct contact other animal species, the habit of scavenging garbage hunting in search food, drinking standing water, smelling animals' urine, licking female genitalia sexual act itself. The objective this study was to detect antibodies anti-Toxoplasma gondii, anti-Leptospira spp., anti-Brucella canis abortus dogs housed shelters at Umuarama city, Paraná,...
Toxoplasmosis, caused by Toxoplasma gondii, has traditionally been considered an important water and foodborne protozoonosis with public health considerations. Although felids play a well-established role as definitive hosts, canine epidemiological involvement in the parasite's life cycle remains questionable controversial. The increasing closeness of human-dog bond, particularly seen urban settings, recognized historically unprecedented worldwide movement. Sharing daily lives same...
Although leptospirosis has been considered a major concern in urban areas, no study to date spatially and simultaneously compared both owner dog serology households of cities. Accordingly, the aim present was assess seroprevalence Leptospira antibodies, evaluate associated risk factors conduct spatial analyses 565 randomly selected households, which included 597 owners 729 dogs Londrina, Southern Brazil. Seropositivity by MAT were detected 11/597 (1.84%) 155/729 (21.26%) dogs. The evaluated...
The aim of this study was to investigate the presence DNA Borrelia burgdorferi sensu lato (s.l.) in ticks that feed on horses used for animal traction rural Jataizinho, Parana, Brazil. Between February and June 2008, a total 224 collected which 75% were identified as Dermacentor nitens 25% Amblyomma cajenense. To amplify B. s.l. DNA, intergenic space region (ISR) between 5S (rrf) 23S (rrl) rRNA genes targets nested-PCR. Two D. species positive Both showed fragment 184 bp, but sequencing...
The aim of this study was to conduct a serological survey for Lyme diseases, brucellosis, leptospirosis and toxoplasmosis identify the risk variables related these zoonoses in humans living rural area Jataizinho, state Parana, Brazil. A total 63 properties were surveyed. Additionally, 207 serum samples collected from inhabitants tested indirect immunofluorescence (IFI) western blots (WB) performed detect Borrelia burgdorferi (sensu lato); tamponated acidified antigen test (AAT)...
A proximidade da relação homem-animal tem aumentado o risco de transmissão doenças caráter zoonótico. O objetivo desse trabalho foi determinar a prevalência anticorpos IgG anti-Toxoplasma gondii, anti- Leishmania spp. e Leptospira nos cães gatos atendidos pelo Projeto Controle Natalidade (PCN) anos 2004 2012 verificar significância estatística variáveis ambientais população estudo à presença dos agentes infecciosos. Amostras sangue 271 415 foram colhidas por venopunção jugular ou cefálica...
Abstract Toxoplasmosis is a worldwide zoonosis with important public health implications. The aims of this study were to determine and identify factors associated the seroprevalence anti-Toxoplasma gondii antibodies in humans dogs from Jataizinho, Parana State, Brazil. Serum samples 280 766 dogs, rural urban areas, tested by indirect immunofluorescent antibody test. Positive dilutions ≥ 1:16. Epidemiological informations obtained through an individual questionnaire data tabulation was...
This study examined the seropositivity of
ABSTRACT: The present study aimed to investigate an abortion outbreak in a dairy goat herd the municipality of Arapoti, Parana, Brazil. At beginning outbreak, blood samples were collected from 33 goats with clinical signs; later, whole herd, two cats and dogs. Milk 78 lactating goats. Four environmental soil four feed residue feeders too. Immunofluorescence antibody test (IFA) was used for serodiagnosis, molecular analysis conducted by means polymerase chain reaction (PCR), isolation...
INTRODUCTION: Canine visceral leishmaniasis (CVL) is a public health problem, and its prevalence associated with the coexistence of vectors reservoirs. CVL protozoonosis caused by Leishmania infantum that endemic in southeast region Brazil. Thus, vector canine reservoir control strategies are needed to reduce burden. This study aimed verify seroprevalence epidemiology municipality Southeast Brazil initiate disease strategies. METHODS: A total 833 dogs were subjected Dual Path Platform (DPP)...
The aim of this study was to demonstrate the Leptospirosis occurrence in stray dogs found campus Universidade Estadual de Londrina – PR., from July September 2007. MAT (Microscopic Agglutination Test) made as diagnostic serological test 33 serum samples and direct dark-field microscopy (DFM) 10 urine samples. In MAT, seven (21,21%) reacted antibodies against serovars Canicola, Pyrogenes Castellonis were detected with titles 200 400. DFM, visualized typical Leptospira spp. morphology motility...
O estudo da prevalencia de caes domiciliados em areas urbanas com anticorpos antileptospiras e variaveis associadas ao risco infeccao, pode auxiliar na identificacao dos sorovares presentes regiao sugerir os reservatorios envolvidos nesta importante zoonose. objetivo deste trabalho foi determinar a 653 369 domicilios distribuidos area urbana do municipio Jataizinho, PR, estudar infeccao por leptospiras nesses animais.

As enteroparasitoses causadas por helmintos e protozoários infectam humanos animais no mundo todo, sua prevalência está relacionada à falta de hábitos higiene pessoal em consequência do seu ciclo oral-fecal. No Brasil, como não são doenças notificação obrigatória, é possível que esteja subnotificada.

The presence of DNA and anti-Leishmania spp. antibodies in the serum 112 healthy horses was investigated by evaluating physical examination, from a rural society located north central region Paraná. antigens Leishmania amazonensis, braziliensis, infantum were used to perform indirect enzyme-linked immunosorbent assay, where it possible detect reaction 27.67% samples. These also subjected real-time quantitative PCR, which confirmed 67.34% tested results show that animals previously exposed...
Intestinal parasites inhabit the intestinal tract of humans and animals, causing damages whose severity depends on several factors related to parasite host. Immunocompromised individuals are more likely develop severe forms parasitic infestation. The diagnosis gastrointestinal parasitosis is mainly performed by examination feces, which consists direct visualization identification eliminated through feces. These tests generally low sensitive microscope slides contain a large number...
