The study of the parasitic fungus Sphaeropsis sapinea life cycle shows that the conidia disseminate most massively during the period April-May, i. e. during the critical time of infection, but also during the period June-August. Infection can occur through the buds in the spring, before their flushing, but also in the summer of the year of their development. Infection occurs most frequently through the bark of the young shoots, because of which they die while needle infections mostly lead to the so-called localized infections. Both male and female flowers can be infected, as well as the current-year and second-year cones. In some cases this fungus can behave as a latent parasite, i. e. endophyte.

Abstract During 2017-2019, leaves and stems with dark brown lesions containing hypophyllous telia surrounded by chlorotic halos were collected from Sphaeralcea angustifolia plants located in Axapusco, State of Mexico. Based on the morphological characteristics of pycnia, aecia and telia observed by light microscopy and scanning electron microscopy, the fungus Puccinia sherardiana was identified. Uredial stage was not present during the observation period. Identity verification was carried out by phylogenetic analysis with sequences of part of the 28S gene from ribosomal DNA. In addition, pathogenicity tests were done on S. angustifolia leaves by inoculating teliospores. The inoculated plants developed symptoms 15 days after inoculation, the signs beginning with the presence of aecia in the epidermis of the host and later telia were formed, completing the Koch Postulates. Puccinia sherardiana was previously described as a rust with a microcyclic life cycle on species of the genera Alcea, Malvastrum, Sidalcea and Sphaeralcea , belonging to the Malvaceae family, however, this study revealed that this plant pathogenic fungus has a demicyclic life cycle.

Toxoplasma Gondii Infection

Toxoplasma gondii (T. gondii) is a protozoan parasitizing all warm-blooded mammals, including humans. The main source of infection is contact with the feces of infected animals, particularly housecats, – the definitive hosts, in which T. gondii completes its life cycle. Alternative sources of infection are contact with and consumption of contaminated meat (particularly pork), transmission from mother to fetus, and infection by oocytes present in the soil or in polluted water. T. gondii is geographically ubiquitous; its level of seroprevalence is estimated to range from about 3% in South Korea to 76% in Costa Rica. Despite great efforts and considerable progress, toxoplasmosis remains a serious health threat worldwide. There is currently no available vaccine, and anti-toxoplasmosis drugs have substantial side effects and are not very effective. Furthermore, studies show that the parasite is able to develop resistance to them. Many recent studies have focused on how T. gondii is linked to psychiatric diseases and neurocognitive processes. Research has shown a correlation between T. gondii infection and schizophrenia.
