The role of zoos in conservation programmes has increased significantly last decades, and the health captive animals is essential to guarantee success such programmes. However, zoo birds suffer from parasitic infections, which often are caused by malaria parasites related haemosporidians. Studies determining occurrence diversity these parasites, aiming better understanding infection influence on fitness birds, limited. In 2011–2015, prevalence Plasmodium spp. Haemoproteus was examined blood...
Plasmodium (Novyella) nucleophilum was identified using microscopy and PCR, in an Egyptian Goose (Alopochen aegyptiacus) that died São Paulo Zoo, Brazil. This parasite is characterized by elongated gametocytes, small meronts with scant cytoplasm, less than eight merozoites mainly for having all the stages appressed to nuclei of infected erythrocytes. Additionally, (Haemamoeba) sp. same blood sample. The latter lacks nucleophilic large roundish trophozoites, each a prominent centrally...
Chagas disease (ChD) is a neglected tropical caused by Trypanosoma cruzi, endemic in 21 countries across the Americas, with increasing cases globally. In São Paulo, Brazil, vector control has focused on Triatoma infestans, but secondary triatomine species continue to pose transmission risks. This study aimed investigate prevalence of T. cruzi feces and characterize its genetic diversity using molecular techniques. Fecal samples were collected from 570 triatomines 25 municipalities followed...
Determining the prevalence and local transmission dynamics of parasitic organisms are necessary to understand ability parasites persist in host populations disperse across regions, yet dynamics, diversity, distribution haemosporidian remain poorly understood. We studied prevalence, distributions avian genera
Non-human primates (NHPs) have been shown to be infected by parasites of the genus Plasmodium, etiological agent malaria in humans, creating potential risks zoonotic transmission. Plasmodium brasilianum, a parasite species similar P. malariae described NHPs from Central and South America, including Brazil. The merozoite surface protein 1 (MSP1), besides being vaccine candidate, is highly immunogenic. Due such properties, we tested this for diagnosis infection. We used recombinant proteins...
Avian malaria parasites are widespread transmitted by Culicidae insects belonging to different genera. Even though several studies have been conducted recently, there is still a lack of information about potential vectors Plasmodium parasites, especially in Neotropical regions. Former with free-living and captive animals São Paulo Zoo showed the presence Haemoproteus species. In 2015, pilot study was at zoo collect mosquitoes order find out (i) which species present area, (ii) what their...
Blood parasites of the Haemosporida order, such as Plasmodium spp. responsible for malaria, have become focus many studies in evolutionary biology. However, there is a lack molecular investigation haemosporidian wildlife, genus Polychromophilus. Species this neglected exclusively been described bats, mainly Europe, Asia, and Africa, but little known about its presence genetic diversity on American continent. Here, we investigated 406 bats from sites inserted remnant fragments Atlantic Forest...
The identification of mosquito species is necessary for determining the entomological components disease transmission. However, can be difficult in that are morphologically similar. cytochrome c oxidase subunit I (COI) DNA barcode region considered a valuable and reliable diagnostic tool recognition, including those belong to complexes. Mansonia mosquitoes found forests near swampy areas. They nocturnal highly attracted light. Hematophagous adult females exhibit aggressive biting behavior...
Plasmodium malariae is the third most prevalent human malaria-causing species and has a patchy, but ample distribution in world. Humans can host parasite for years without presenting significant symptoms, turning its diagnosis control into difficult task. Here, we investigated immunogenicity of recombinant proteins P. MSP1.Five regions PmMSP1 were expressed Escherichia coli as GST-fusion immunized BALB/c mice. The specificity, subtyping, affinity raised antibodies evaluated by enzyme-linked...
Plasmodium malariae has a wide geographic distribution, but mainly at very low parasitemias and in co-infections, leading to an underestimated prevalence of this species. Studies for the detection antibodies against recombinant proteins are increasingly used map geographical distributions, seroprevalence transmission intensities malaria infection. However, no seroepidemiological survey using P. been conducted Brazil. This work evaluated antibody response serum samples individuals from...
