Abstract

Toxoplasma gondii is a zoonotic parasite with global distribution capable of infecting homeothermic animals. Transmission of protozoan to humans includes ingestion of water and raw food contaminated with sporulated oocysts, ingestion of raw or undercooked meat with tissue cysts, and tachyzoites' transplacental transmission. Fresh goat milk intake has already been linked to human toxoplasmosis outbreaks, but little is known about the infectious potential of this biological sample. Accordingly, the aim of the present study is to assess the survival and infectivity of T. gondii tachyzoites in fresh goat milk samples through an experimental protocol to detect this parasite via bioassay carried out with a murine model, DNA amplification, and serology. Swiss Webster mice were inoculated with fresh goat milk samples contaminated with different T. gondii RH strain tachyzoite concentrations per milliliter and stored for different refrigeration times. Animals showing clinical signs compatible to toxoplasmosis were euthanized. Milk samples contaminated with high parasitic loads and kept for a shorter refrigeration time were the most lethal ones. No significant differences were observed between mean death rates recorded for different goat milk contamination concentrations (p = 0.1888), and for the refrigeration time, contaminated milk samples were kept under (p = 0.9440). T. gondii DNA was amplified in all contaminated milk samples, but only one of the surviving mice was serologically positive. Results of the present study have shown T. gondii survival and infectivity in fresh goat milk samples, and it highlights its significant risk for public health. Therefore, molecular methods must be the tests of choice when milk samples are used to assess infection caused by protozoan in goats' dairy products. [ABSTRACT FROM AUTHOR]

Abstract

Toxoplasma gondii is a highly prevalent zoonotic parasite in Brazil capable of infecting mammals and birds. The increase in the urban populations of pets and the narrowing of the human–animal relationship can facilitate the transmission of important public health zoonoses, such as toxoplasmosis. This study aimed to evaluate the frequency and spatial distribution of T. gondii infection and its risk factors in domiciled dogs and cats attended at the Jorge Vaitsman Institute, Rio de Janeiro. Serum samples from 400 dogs and 272 cats were evaluated by an indirect fluorescent antibody test (IFAT) for IgG anti-T. gondii antibodies. Epidemiological questionnaires were used to interview the animals’ owners to identify risk factors for infection. Of the total, 34% (136/400) of dogs and 8.1% (22/272) of cats had anti-T. gondii antibodies. Breed (OR: 2.10–95%, CI 1.27–3.46) was a risk factor for dogs, while sex (OR: 3.40–95%, CI 1.10–10.52) and homemade food consumption (OR: 8.49–95%, CI 2.48–29.05) were risk factors for cats. Offal consumption was considered a risk factor for both species evaluated (OR: 2.74–95%, CI 1.38–5.43 for dogs; OR: 7.66–95%, CI 1.24–47.29 for cats). The spatial analysis showed that T. gondii seropositive animals were widely distributed in the metropolitan region of Rio de Janeiro state, with a concentration observed mainly in the west and north zones of Rio de Janeiro city. The results emphasize the importance of adopting prophylactic measures to control T. gondii transmission in domiciled dogs and cats in Rio de Janeiro, contributing positively to public health.

Abstract

Urban canine and feline populations are expanding worldwide, a fact that can boost the transmission of zoonotic parasites. Thus, it is necessary understanding dog and cat owners’ profile, as well as their perceptions about zoonoses, to develop preventive strategies based on the One Health approach. The aim of the current study is to compare the profile of dog and cat owners, whose domestic pets were treated at Jorge Vaitsman Veterinary Medicine Center, Rio de Janeiro, Brazil. Dog and cat owners, whose domestic pets were treated in the routine service of the aforementioned medical clinic, from August 2017 to November 2018, filled a structured questionnaire comprising closed questions in order to collect information about their socioeconomic profile, hygiene habits, animal care and knowledge about parasites. Comparative analysis was applied to data collected from dog and cat owners, based on using Fischer’s Exact Test or Pearson’s Chi-square. In total, 350 individuals - 244 dog owners and 106 cat owners - filled the questionnaire. The comparative analysis of socioeconomic profile, animal care, sanitary practices and knowledge about parasites did not show differences between dog and cat owners (p≥0.05). Animal vaccination and deworming practices were significantly more prevalent among dog owners than among cat owners (p≤0.05). Overall, respondents have shown lack of knowledge about parasitic zoonoses. Results in the current study have evidenced the need of mediating and promoting information about potentially zoonotic parasitic agents among domestic pet owners, as well as the key role played by veterinarians as mediators of primary prevention measures against these agents., As populações urbanas de cães e gatos estão em expansão, o que pode facilitar a transmissão de parasitas zoonóticos. Nesse sentido, é necessário conhecer o perfil dos donos de cães e gatos e suas percepções sobre zoonoses para construir estratégias preventivas em uma abordagem em Saúde Única. Este estudo teve como objetivo comparar o perfil dos donos de cães e gatos atendidos no Centro de Medicina Veterinária Jorge Vaitsman, Rio de Janeiro, Brasil. Entre agosto de 2017 e novembro de 2018, proprietários de cães e gatos atendidos na rotina da clínica médica responderam a um questionário estruturado composto por questões fechadas relacionadas ao seu perfil socioeconômico, hábitos de higiene, cuidados com os animais e conhecimento sobre parasitas. A análise comparativa dos dados obtidos de proprietários de cães e gatos foi realizada por meio do Teste Exato de Fischer ou Qui-quadrado de Pearson. No total, 350 indivíduos responderam ao questionário, sendo 244 donos de cães e 106 donos de gatos. A análise comparativa do perfil socioeconômico, cuidados com os animais, práticas sanitárias e conhecimento sobre parasitos não mostrou diferenças entre proprietários de cães e gatos (p≥0,05). As práticas de vacinação e desparasitação dos animais foram significativamente mais frequentes entre os donos de cães do que entre os donos de gatos (p≤0,05). De maneira geral, foi possível evidenciar entre as respostas recuperadas um desconhecimento sobre zoonoses parasitárias. Os resultados obtidos evidenciam a necessidade de mediação e divulgação de informações sobre agentes parasitários potencialmente zoonóticos para os proprietários, destacando os veterinários, no papel de mediadores das medidas de prevenção primária contra esses agentes.

Abstract

A detecção de Toxoplasma gondii no sangue venoso e na placenta de gestantes pela reação de polimerase em cadeia pode facilitar o diagnóstico pré-natal da toxoplasmose congênita. Foram avaliadas gestantes IgM-reagentes e os seus filhos. Além das dosagens de IgG, IgM, IgA e reação de avidez de IgG (MEIA), foram realizadas a técnica de imunoperoxidase e a inoculação em camundongos. De cada amostra foi efetuada amplificação gênica com primers do gene B1 e novos primers do gene TGR (chamados ABGTg7 C1 e N1). É preciso observar que o tratamento poderia ser responsável por uma diminuição da infecção. Desta forma, o diagnóstico negativo confirmaria a eficiência do tratamento preventivo na replicação parasitária no útero. A reação de polimerase em cadeia mostrou-se sensível e específica; evidenciou a presença de um a dez taquizoítas; pode ser utilizada com segurança e confiabilidade, além de tornar rápido o diagnóstico da toxoplasmose congênita, sendo, assim, ferramenta importante na avaliação pré-natal.

Abstract

The increasingly urban nature of the population has led many people to choose independent pets, such as cats. This situation has also made it possible for these animals to be abandoned, thus increasing the numbers of cats on the streets and in shelters. These animals can act as a source of infection for other hosts. Between 2014 and 2015, the frequency of gastrointestinal parasites in captive and stray cats in the municipality of Rio de Janeiro was analyzed. Ninety-one fecal samples were collected from captive cats and 172 from stray cats. Centrifugal sedimentation and flotation techniques were used. The frequency of parasites among the stray cats was 77.3%, and this was significantly higher than the frequency observed in captive cats (49.5%). Helminths were detected more frequently, and hookworms were the parasites most detected. Toxocara cati, Cystoisospora sp. and Dipylidium caninum were also detected. No statistical difference in the frequency of parasites was observed between the sexes among the captive cats. However, among the stray cats, males (85.5%) presented higher positivity than females (71.8%). The high frequency of hookworms, which are the agent for “cutaneous larva migrans” in humans, shows the need to control parasitic infections among the cats studied. Resumo O aumento da população urbana contribuiu para que muitas pessoas escolhessem um animal de estimação independente, como o gato. Esta situação possibilita o abandono desses animais, aumentando o número de gatos nas ruas e nos abrigos. Esses animais, então, podem servir como fonte de infecção para outros hospedeiros. Entre 2014 a 2015 foi analisada a frequência de parasitos gastrintestinais em gatos cativos e de rua na cidade do Rio de Janeiro. Foram coletadas 91 amostras fecais de gatos cativos e 172 de gatos de rua, sendo essas processadas pelas técnicas de centrífugo sedimentação e flutuação. A frequência de parasitos nos gatos de rua foi 77,3%, sendo esta significativamente maior do que a evidenciada nos cativos, 49,5%. Os helmintos foram mais detectados, sendo ancilostomídeos os parasitos mais evidenciados. Também foram detectados, Toxocara cati, Cystoisospora sp. e Dipylidium caninum. Não foi observada diferença estatística na frequência de parasitos entre o sexo nos gatos cativos, porém nos de rua, os machos (85,5%) apresentaram positividade maior do que as fêmeas (71,8%). A elevada frequência de ancilostomídeos, agente da “Larva Migrans Cutânea” no homem, demonstra a necessidade de controle das infecções parasitárias nos gatos estudados.
