“…Apesar do leite cru não ser a principal via de transmissão da toxoplasmose, ele pode veicular o parasito durante a fase aguda de parasitemia, portanto deve ser ingerido somente após a pasteurização ou fervura (27) . A toxoplasmose pode ser adquirida pela ingestão de alimentos contaminados, em especial carnes cruas ou mal passadas, principalmente de porco e de carneiro contendo cistos, e vegetais que abriguem os oocistos, por terem tido contato com as fezes eliminadas por felídeos contendo oocistos ou material contaminado por elas mesmas (28)(29) .…”

A toxoplasmose é uma zoonose mundialmente distribuída causada por um protozoário intracelular, o Toxoplasma gondii, que é capaz de infectar o homem, aves e mamíferos. A toxoplasmose congênita ocorre quando a gestante adquire a primoinfecção durante a gravidez e transmite via transplacentária ao feto. Assim o presente trabalho teve como objetivo analisar o conhecimento das gestantes frente a este assunto. Foi realizado um estudo descritivo de abordagem quantitativa realizada em uma Unidade Básica de Saúde. A amostra da pesquisa foi do tipo não probabilístico por conveniência, contemplando 40 gestantes em acompanhamento pré-natal. Frente aos resultados analisados, verificou-se que o desconhecimento das gestantes sobre a toxoplasmose está relacionado à falta de orientações e informações dos profissionais de saúde durante as consultas de pré-natal, o que justifica os hábitos de vida e alimentares inadequados favorecendo uma possível infecção. O papel da Enfermagem é de fundamental importância neste aspecto, um pré-natal respaldado evita agravos durante gestação e pós-parto.Descritores: Toxoplasmose congênita, Formas de transmissão, Papel do profissional de enfermagem, Gravidez, Cuidado pré-natal

“…On the other hand, it is not clear whether T. gondii infection might be involved in vaginal infections. Experimental vaginal infection with T. gondii has been demonstrated in goats [ 31 ]; however, it is unknown whether T. gondii can cause vaginal pathology. Further research to determine the role of T. gondii in vaginal infections is needed.…”

Some symptoms of menopause have also been described in patients with toxoplasmosis. Whether Toxoplasma gondii (T. gondii) infection has any influence on clinical manifestations of menopause is yet unknown. We sought to determine whether T. gondii exposure is associated with symptoms and signs of menopause. We performed a cross-sectional study of women attending a public health center in Durango City, Mexico. Participants were examined for the presence of anti-Toxoplasma IgG and IgM antibodies using enzyme-linked immunoassays. A questionnaire including 47 symptoms and signs potentially associated with menopause was applied. Association of seroprevalence for T. gondii with clinical characteristics of women was assessed by bivariate and multivariate analyses. Bivariate analysis showed that bouts of rapid heartbeat, breast pain, electric shock sensation, dizziness, digestive problems, low back pain, and migraine were associated with seropositivity to either IgG anti-T. gondii alone or both IgG and IgM anti-T. gondii. Breast pain was the only variable that was found to be associated with IgG seropositivity to T. gondii by multivariate analysis: (OR = 2.84; 95% CI: 1.35–5.90; P = 0.005). Our results suggest that T. gondii exposure may influence on the clinical manifestations of menopause. Results deserve further research.

“…Moreover, in spite of causing substantial abortion or mortality in certain secondary host species such as sheep and humans, some species, in particular mice and rats, appear to maintain infection through congenital or neonatal transmission [49–51]. Several cases of successful sexual transmission, many with consequent vertical transmission to their progeny, have also been documented in experimental studies involving, but not exclusive to, rats [52], dogs [53], sheep [54,55] and goats [56,57]. Sexual transmission through T. gondii tachyzoites in semen has also been proposed as a potential transmission mode for human toxoplasmosis [58,59], but it remains unknown how prevalent or successful these different modes are under natural conditions.…”

Multi-host infectious agents challenge our abilities to understand, predict and manage disease dynamics. Within this, many infectious agents are also able to use, simultaneously or sequentially, multiple modes of transmission. Furthermore, the relative importance of different host species and modes can itself be dynamic, with potential for switches and shifts in host range and/or transmission mode in response to changing selective pressures, such as those imposed by disease control interventions. The epidemiology of such multi-host, multi-mode infectious agents thereby can involve a multi-faceted community of definitive and intermediate/secondary hosts or vectors, often together with infectious stages in the environment, all of which may represent potential targets, as well as specific challenges, particularly where disease elimination is proposed. Here, we explore, focusing on examples from both human and animal pathogen systems, why and how we should aim to disentangle and quantify the relative importance of multi-host multi-mode infectious agent transmission dynamics under contrasting conditions, and ultimately, how this can be used to help achieve efficient and effective disease control.This article is part of the themed issue ‘Opening the black box: re-examining the ecology and evolution of parasite transmission’.
