Colonic epithelial nodular hyperplasia associated with strongyloidiasis in cats in the Amazon region, Pará State, Brazil Ciência Rural
Moura,Márcio Alan Oliveira; Jorge,Ediene Moura; Nascimento,Kelly Karoline Gomes do; Riet-Correa,Gabriela; Abel,Isis; Cavalcante,Gustavo Goes; Oliveira,Carlos Alberto de; Bezerra Júnior,Pedro Soares.
ABSTRACT: Strongyloides spp. are intestinal parasites that affect several animal species. Four species of the genus have been reported in domestic cats: S. felis, S. planiceps, S.stercoralis and S. tumefaciens . Reports describing infection by these nematodes in domestic cats in Brazil are scarce. This study aimed to describe the pathological features of Strongyloides spp. parasitism in two cats in the Amazon region, state of Pará, Brazil. During the necropsy of the two cats, numerous whitish nodules approximately 0.2cm in diameter were observed in the wall of the large intestine. The nodules were conspicuous in the colonic mucosa and exhibited a punctate aperture facing the center of the lumen. Microscopically, these nodules were formed by projections...

Cross-disciplinary approaches for measuring parasitic helminth viability and phenotype Anais da ABC (AABC)
Peak,Emily; Hoffmann,Karl F.
Parasitic worms (helminths) within the Phyla Nematoda and Platyhelminthes are responsible for some of the most debilitating and chronic infectious diseases of human and animal populations across the globe. As no subunit vaccine for any parasitic helminth is close to being developed, the frontline strategy for intervention is administration of therapeutic, anthelmintic drugs. Worryingly, and unsurprising due to co-evolutionary mechanisms, many of these worms are developing resistance to the limited compound classes currently being used. This unfortunate reality has led to a renaissance in next generation anthelmintic discovery within both academic and industrial sectors. However, a major bottleneck in this process is the lack of quantitative methods for...

Efficacy of Ocimum gratissimum essential oil against the monogenean Cichlidogyrus tilapiae gill parasite of Nile tilapia Arq. Bras. Med. Vet. Zootec.
Meneses,J.O.; Couto,M.V.S. do; Sousa,N.C.; Cunha,F. dos S.; Abe,H.A.; Ramos,F.M.; Chagas,E.C.; Chaves,F.C.M.; Martins,M.L.; Maria,A.N.; Carneiro,P.C F.; Fujimoto,R.Y..
ABSTRACT The phythotherapy is an alternative to use of chemotherapeutical agents against monogenean infection. This study evaluated the anthelmintic activity of essential oil Ocimum gratissimum against monogenean Cichlidogyrus tilapiae as well as its acute toxicity in tilapia juveniles. The mean lethal concentration (LC50) and different concentrations of the essential oil, both in vitro and in vivo assays (short and long-term baths) were assessed. The LC50 was 40.70mg.L-1 and in the in vitro assay this concentration showed 80% efficacy at the last two hours and in the in vivo assay 65.87% efficacy in long-term bath. However, it provoked morphological alterations on the gills such as hyperplasia and edema. The parasites exposure at the highest concentration...

Epidemiologia da helmintose bovina no Pantanal Mato-Grossense: 2.sub-regiao da Nhecolandia, 1978/1979. Infoteca-e
CATTO, J. B.; FURLONG, J..
O Pantanal Mato-Grossense, uma extensa planicie aluvial de aproximadamente 140.000 km2, divide-se em diversas sub-regioes de acordo com suas caracteristicas e tem como principal atividade economica a criacao de bovinos de corte. A sub-regiao da Nhecolandia se caracteriza por solos extremamente arenosos, topografia plana e presenca de muitas lagoas. A precipitacao pluviometrica media anual no local de estudo, obtida de dados coletados nos ultimos quatro anos, e de 1210 mm, sendo que 75% ocorrem de outubro a marco. A temperatura media mensal oscila entre 20 o e 30 oC. Com o objetivo de estudar a epidemiologia das nematodioses gastrintestinais dos bovinos, a UEPAE de Corumba, a partir de 1976, vem realizando necropsias mensais em bovinos para identificar as...

First record of Philometra katsuwoni (Nematoda, Philometridae), a parasite of skipjack tuna Katsuwonus pelamis (Perciformes, Scombridae), off South American Atlantic Coast Biota Neotropica
Cárdenas,Melissa Querido; Moravec,František; Kohn,Anna.
The nematode Philometra katsuwoni Petter & Baudin-Laurencin, 1986, a gonad-infecting parasite of Katsuwonus pelamis (Linneaus 1758), originally described from the Gulf of Guinea, is reported for the first time from the coastal zone of Rio de Janeiro State, Brazil. As compared with the original description, the males of the Brazilian material are generally somewhat larger and their right spicule and the gubernaculum are longer. The subgravid female is described for the first time. It is characterized by the anterior inflation of the esophagus and by the presence of two distinct caudal lobes.

First report of multiple anthelmintic resistance in nematodes of sheep in Colombia Anais da ABC (AABC)
Gárcia,Carlos M.B.; Sprenger,Lew K.; Ortiz,Efraín B.; Molento,Marcelo B..
This study aimed to report the presence of parasites resistant to the most used anthelmintic drugs in sheep in Colombia. Four farms (denominated farm 1, 2, 3 and 4) were selected where the animals were not treated with anthelmintics for two months before the trial. Animals with faecal egg count (FEC) above 150 and of different ages were allocated into six groups, each consisting of at least 5 animals. The drugs and dosages used were: ivermectin 1% (0.2 mg/kg), albendazole 25% (5 mg/kg), fenbendazole 10% (5 mg/kg), levamisole 10% (5 mg/kg), and moxidectin 1% (0.2 mg/kg). Anthelmintic efficacy was determined by the FEC reduction test (FECRT) with a second sampling 14 days post-treatment. The efficacy of albendazole and fenbendazole at farm 1 was above 95%,...

Involvement of nitric oxide and its up/down stream molecules in the immunity against parasitic infections BJID
Nahrevanian,Hossein.
Nitric oxide (NO) is a potent mediator with diverse roles in regulating cellular functions and signaling pathways. The NO synthase (NOS) enzyme family consists of three major isoforms, which convey variety of messages between cells, including signals for vasorelaxation, neurotransmission and cytotoxicity. This family of enzymes are generally classified as neuronal NOS (nNOS), endothelial NOS (eNOS) and inducible NOS (iNOS). Increased levels of NO are induced from iNOS during infection; while eNOS and nNOS may be produced at the baseline in normal conditions. An association of some key cytokines appears to be essential for NOS gene regulation in the immunity of infections. Accumulating evidence indicates that parasitic diseases are commonly associated with...

Occurrence of Aelurostrongylus abstrusus (Railliet, 1898) larvae (Nematoda: Metastrongylidae) infecting Achatina (Lissachatina) fulica Bowdich, 1822 (Mollusca: Gastropoda) in the Amazon region Acta Amazonica
Andrade-Porto,Sanny Maria de; Souza,Kelly Cristina Pereira de; Cárdenas,Melissa Querido; Roque,Rosemary A.; Pimpão,Daniel Mansur; Araújo,Cleusa Suzana; Malta,José Celso de Oliveira.
Achatina fulica or "giant African snail" is an exotic species, considered to be one of the world's hundred most invasive species, causing serious environmental damages. In the present study we report, for the first time, the occurrence of Aelurostrongylus abstrusus infecting A.fulica in the Amazon region. This nematode is described parasitizing mainly the pulmonary system of felines, which causes "aelurostrongilose", also known as feline cardio-pulmonary strongyloidosis. New morphometric data of third stage larvae are presented herein. The present study demonstrated that 40% of all the snails were infected by A. abstrusus. Achatina fulica specimens were collected from three different areas in Manaus namely: rural; east and west areas. The east area...

PARASITIC HELMINTHS INFECTING Eucinostomus melanopterus AND Eugerres plumieri (PERCIFORMES: GERREIDAE), FROM BOCA DEL RIO, VERACRUZ, MÉXICO Acta biol.Colomb.
MONTOYA-MENDOZA,Jesús; MUÑOZ-NIETO,Gilberto; CHÁZARO-OLVERA,Sergio; MENDOZA-FRANCO,Edgar F; LANGO-REYNOSO,Fabiola; CASTAÑEDA-CHÁVEZ,María del Refugio.
ABSTRACT A helminthological examination was carried out on 14 specimens of Eucinostomus melanopterus (flagfin mojarra) and 19 Eugerres plumieri (striped mojarra), of which a total of 461 helminths were collected. As a result, and 12 taxa were registered (five species, five genus and tow family), as follows: four monogeneans, five digeneans (four adults, one metacercaria), one cestode (larva) and tow nematodes (larvae). The highest prevalence was for Neodiplectanum mexicanum (29 %) infecting E. melanopterus and Aristocleidus hastatus (37 %) infecting E. plumieri. Both hosts shared 50 % of recorded species, and none of the identified helminthes represents a zoonotic risk.
