Correlation between climate data and land altitude for Fasciola hepatica infect...
Silva,Ana Elisa Pereira; Freitas,Corina da Costa; Dutra,Luciano Vieira; Molento,Marcelo BeltrãoAbstract Fascioliasis is a food-borne parasitic disease that affects a range of animals, including humans caused by Fasciola hepatica. The present study aimed to determine the spatial distribution of bovine fasciolosis and to assess the correlation between the high Positivity Index (PI) and climate data and land altitude, from 2004 to 2008 and 2010 in Santa Catarina (SC), Brazil. Condemned livers of slaughtered...
South Brazilian farmers’ perceptions concerning sheep tail docking
Stamm,Fabiana de Orte; Molento,Marcelo Beltrão; Molento,Carla Forte MaiolinoABSTRACT: The objective of this study was to better understand farmers’ perceptions regarding sheep welfare and procedures concerning the tail docking of sheep in the state of Parana, Southern Brazil. The study was carried out via telephone interviews or personally with 146 sheep farmers. Twenty-eight farmers (19.2%) did not tail dock; the main reasons given were because they raised short-hair sheep breeds. One...
First reported case of clinical fascioliasis in Santa Catarina, Brazil
Pritsch,Izanara Cristine; Garcia,Raquel Liermann; Douat,Diogo; Schwendler,Ricardo Reis; Buttendorf,Magda Rejane Bordin; Molento,Marcelo BeltrãoAbstract Fascioliasis is a food-borne anthropozoonotic disease caused by Fasciola hepatica that affects multiple hosts, including humans. We herein report the first case of human fascioliasis in the state of Santa Catarina, Brazil. A 57-year-old female patient complaining of abdominal pain was admitted to the hospital for a clinical investigation. The diagnosis of F. hepatica was confirmed by ultrasound and ind...
Fascioliasis in buffaloes: A 5-year forecast analysis of the disease based on a...
Pritsch,Izanara Cristine; Stanula,Emanoelli Cristini Augustinhak; Anjos,Alan dos; Bertot,José Alberto; Molento,Marcelo BeltrãoAbstract In South America, fascioliasis caused by the trematode Fasciola hepatica is an anthropozoonosis disease associated with significant economic losses and poor animal welfare. The objective of this study was to determine the prevalence of F. hepatica in the liver of buffaloes slaughtered from 2003 to 2017 in Brazil, and to perform a forecast analysis of the disease for the next five years using the Autore...
Can the strategies for endoparasite control affect the productivity of lamb pro...
Fernandes,Maria Angela Machado; Salgado,Jordana Andrioli; Peres,Mylena Taborda Piquera; Campos,Karla Francisca Duarte; Molento,Marcelo BeltrãoABSTRACT The objective of this study was to evaluate the productivity and carcass traits of unweaned Suffolk lambs finished on pasture and subjected to three strategies for endoparasite control: prophylactic treatment of all animals every 28 days; treatment of animals with a cut off number of nematode fecal egg count (FEC) ≥ 700; and treatment of animals using the FAMACHA scores ≥ 3. Average daily weight gain (...
Sheep polyclonal antibody to map Haemonchus contortus mimotopes using phage dis...
Buzatti,Andréia; Fernandez,Arnielis Diaz; Arenal,Amilcar; Pereira,Erlán; Monteiro,Alda Lucia Gomes; Molento,Marcelo BeltrãoAbstract The aim of this study was to evaluate phage display technology for mapping Haemonchus contortus mimotopes. We screened the PhD-7 Phage Display Peptide Library Kit with a sheep polyclonal antibody against H. contortus. After four rounds of selection, 50 phage peptide clones were selected by biopanning and sequenced. Two clones displaying peptide mimotopes of H. contortus proteins were chosen for sheep i...
Seroprevalence and seroincidence of Leptospira infection in dogs during a one-y...
Morikawa,Vivien Midori; Bier,Daniele; Pellizzaro,Maysa; Ullmann,Leila Sabrina; Paploski,Igor Adolfo Dexheimer; Kikuti,Mariana; Langoni,HélioINTRODUCTION: Leptospirosis is a zoonosis that affects both humans and animals. Dogs may serve as sentinels and indicators of environmental contamination as well as potential carriers for Leptospira. This study aimed to evaluate the seroprevalence and seroincidence of leptospirosis infection in dogs in an urban low-income community in southern Brazil where human leptospirosis is endemic. METHODS: A prospective ...

Sprenger,Lew Kan; Campestrini,Luciano Henrique; Yamassaki,Fábio Tomio; Buzatti,Andréia; Maurer,Juliana Bello Baron; Baggio,Selma Faria ZawadzkiResumo O objetivo deste estudo foi avaliar a eficácia do extrato hidroalcoólico de Artemisia annua frente a oocistos de Eimeria sp. em camas contaminadas. O extrato foi produzido com 7 dias de percolação a 4°C, sendo posteriormente realizada a marcha fitoquímica; dosagem de fenóis totais, quantificação de artemisinina, ensaio antioxidante e teste de toxicidade. Para testar a atividade anticoccidiana, camas de a...
Nanotechnology: meeting the future of Veterinary Parasitology Research
Cruz,Amilcar Arenal; Molento,Marcelo BeltrãoAbstract: The field of nanotechnology involves an array of different areas of expertize with the application of innovative products in Medicine, Engineering, and to a less extent to Veterinary Medicine. In our opinion, more research is needed, in special to Animal Parasitology, to develop state of the art products to solve old problems. Livestock, pets and wildlife may benefit from products in nanoscale, such a...
Geohelminth contamination of public areas and epidemiological risk factors in C...
Sprenger,Lew Kan; Green,Kerriel Thandile; Molento,Marcelo BeltrãoThis study aimed to investigate the frequency of geohelminthic contamination of public parks and squares in Curitiba, state of Paraná, Brazil, between August and December 2010. A total of 345 samples were collected from 69 sandboxes in different areas and were tested using the Faust, Lutz and Baermann parasitological techniques. Potential risk factors associated with soil contamination were also analyzed. A tot...
