“…Infections in humans in Brazil by Spirometra sp. have been described ( Gomes et al., 1996 , Mentz et al., 2011 ). Massive adult infections by Pseudophyllidea in the small intestine of humans can lead to megaloblastic anemia due to the deficiency caused by vitamin B12 ( Scholz et al., 2009 ) and folic acid consumption by the parasite ( Jimenez et al., 2012 ).…”

An adult free-ranged female maned wolf was rescued from a periurban area subject to anthropogenic disturbances in the Minas Gerais, Brazil. The animal presented poor body condition and anemia. The clinical condition rapidly deteriorated culminating in dead and a necropsy was performed. The main gross lesions were marked anemia and blood content in the intestines accompanied by many types of parasites. The protozoa Rangelia vitalii was identified by histopathological analysis predominantly within the cytoplasm of endothelial cells of capillaries of the small intestine. The lymph nodes, spleen, bone marrow, dermis, lungs and kidney had similar protozoal forms but with mild or moderate intensity. Rangelia vitalii was confirmed by molecular assays. Hepatozoon sp., Leishmania sp., and Entamoeba spp., apparently not related to the clinical signs were also detected. The myriad parasites found in the intestines included nematodes (Ancylostoma caninum, A. braziliensis,, Molineus sp., Pterygodermatites sp., and Trichuris sp.), cestodes (Spirometra sp.) and (acanthocephalans. To our knowledge, R. vitalii was identified in C. brachyurus for the first time. These findings emphasize the fragility of Brazilian ecosystems, especially in disturbed areas, reinforcing the necessity of efforts to preserve these areas and wild carnivores, some of which are threatened with extinction, such as the maned wolf.

“…Sparganosis in humans usually appears as subcutaneous nodules all over the body and can involve the eye, brain, and spinal cord, being characterized as an important zoonotic disease (CHUNG et al, 2012). So far, only four cases of sparganosis have been described in Brazil (states of Rio Grande do Sul, São Paulo and Santa Catarina) (MENTZ et al, 2011), which leads to believe in the risk of occurrence of this zoonosis in Midwestern Brazil. Bowman et al (2002) described three genera of acanthocephalans occurring in cats (Oncicola, Moniliformis and Centrorhynchus) as causes of intestinal disorders.…”

Besides presenting zoonotic potential, helminths of cats are responsible for gastrointestinal, hepatic, and pulmonary diseases. In order to identify the helminthic fauna, prevalence, mean intensity of parasitism (MIP), and mean abundance population (MAP), 146 cats from the metropolitan area of Cuiabá, Midwestern Brazil, were necropsied. In 98 these animals, 12 species of helminths were identified, comprising (species, prevalence, MIP, and MAP, respectively): nematodes (Ancylostoma braziliense [50,68% -53,64 -27,18], Ancylostoma tubaeforme [10,27% -3,6 -0,37], Toxocara cati [4,11% -28,33 -1,16] . Ancylostoma spp., and P. fastosum were the most prevalent with the highest MIP and MAP. We observed the presence of species of helminths with zoonotic potential. This is the first time cats parasitized with Centrorhynchus erraticus are reported in the Americas. That genus is commonly observed in wild animals.Keywords: Identification, quantification, parasitism, Centrorhynchus, zoonosis, prevalence. ResumoHelmintos de gatos são causadores de doenças gastrintestinais, hepáticas e pulmonares, além de apresentarem potencial zoonótico. Com objetivo de identificar a helmintofauna, prevalência, intensidade média de parasitismo (IMP) e abundância média populacional (AMP) foram necropsiados 146 gatos da região metropolitana de Cuiabá, centro-oeste do Brasil. Foram identificadas em 98 animais 12 espécies de helmintos compreendendo (respectivamente espécie, prevalência, IMP e AMP): nematódeos (Ancylostoma braziliense [50,68% -53,64 -27,18], Ancylostoma tubaeforme [10,27% -3,6 -0,37], Toxocara cati [4,11% -28,33 -1,16], Physaloptera praeputialis [2,05% -6,67 -0,14], Capillaria feliscati [3,42% -7,4 -0,25]

“…Recently, a human ocular sparganosis was reported in southern Brazil. 9 It usually manifests as a migrating subcutaneous nodule and can result in blindness, paralysis, and even death. However, cases where there is invasion in the lung or pleura are rare.…”

Multiple pulmonary nodules ParasitesPleural effusion A B S T R A C T Sparganosis in humans is an incidental infection and is known to be associated with eating insufficiently cooked meat of frogs and snakes or drinking unboiled stream water.Although it can involve various internal organs, pulmonary and pleural involvement due to sparganum is rare. Because we recently experienced two cases involving lung parenchyma and pleura that were misdiagnosed as bacterial pneumonia and lung cancer, we herein intend to present them in detail.
