Circadian pattern of Bothrops moojeni in captivity (Serpentes: Viperidae)
Provedor de dados: 80
Autores: Stuginski,DR; Sant'Anna,SS; Fernandes,W; Abe,AS.
Members of the subfamily Crotalinae are considered to be essentially nocturnal and most of the data about these snakes have been collected from the field. Information on how nutritional status affects the movement rate and activity patterns is a key point to elucidating the ecophysiology of snakes. In this study, we distributed 28 lancehead Bothrops moojeni into three groups under distinct feeding regimens after a month of fasting. Groups were divided as follows: ingestion of meals weighing (A) 40%, (B) 20%, or (C) 10% of the snake body mass. Groups were monitored for five days before and after food intake and the activity periods and movement rates were recorded. Our results show that B. moojeni is prevalently nocturnal, and the activity peak occurs in...

Provedor de dados: 80
Autores: Barbosa,PSF; Martins,AMC; Toyama,MH; Joazeiro,PP; Beriam,LOS; Fonteles,MC; Monteiro,HSA.
Snake venom proteins from the C-type lectin family have very distinct biological activities despite their highly conserved primary structure, which is homologous to the carbohydrate recognition region of true C-type lectins. We purified a lectin-like protein (BmLec) from Bothrops moojeni venom and investigated its effect on platelet aggregation, insulin secretion, antibacterial activity, and isolated kidney cells. The BmLec was purified using two chromatographic steps: affinity chromatography and reverse phase high performance liquid chromatography (HPLC). BmLec showed a dose-dependent platelet aggregation and significantly decreased the bacterial growth rate in approximately 15%. During scanning electron microscopy, the profile of Xanthomonas axonopodis...

Histological characterization of Sticholecitha serpentis Prudhoe, 1949 (digenea, bieriidae, sticholecithinae), parasite of Bothrops moojeni Hoge, 1966 (serpentes, viperidae)
Provedor de dados: 80
Autores: Silva,TB.; Rossellini,M.; Dal Pai Silva,M.; Silva,RJ.
The aim of this study was to evaluate the morphology of the species Sticholecitha serpentis Prudhoe, 1949 by means of histological procedures. Helminths were previously fixed in Railliet &amp;amp; Henry solution, uncompressed and were included in 2-hydroxyethyl-methacrylate. Longitudinal and transverse serial sections with a 4-mum thickness were performed in a microtome (Leica RM 2165), stained with haematoxylin-eosin and then analyzed in a computerized image analysis system (Qwin Lite 2.5, Leica). Structures of systematic value, such as oral sucker, acetabulum, prepharynx, pharynx, esophagus, intestinal caeca, vitelline glands, ovary, uterus, cirrus pouch and testicles were described. Structures that were poorly visible in total preparations were also...

Biological characterization of a myotoxin phosphoplipase A2 homologue purified from the venom of the snake Bothrops moojeni
Provedor de dados: 80
Autores: Queiroz,MR; Mamede,CC; Fonseca,KC; Canabrava,LCMN; França,LV; Silva,MC; Stanziola,L; Beletti,ME; Canabrava,HAN; Oliveira,F.
A myotoxin phospholipase A2 homologue, BmooMtx, was isolated from the venom of Bothrops moojeni by a combination of ion-exchange chromatography on DEAE-Sephacel column and gel filtration on Sephadex G-75. SDS-PAGE showed the enzyme to be a monomer with a molecular weight of 16,500. BmooMtx induced release of creatine kinase and morphological analyses indicated that it provoked an intense myonecrosis, with visible leukocyte infiltrate and damaged muscle cells 24 hours after injection. Anti-BmooMTx antibodies partially neutralized the myotoxic activity of BmooMtx and crude B. moojeni venom, as judged by determination of plasma creatine kinase levels and histological evaluation of skeletal muscle in mice. Anti-BmooMTx antibodies were effective in reducing the...

Cytotoxic and pro-apoptotic action of MjTX-I, a phospholipase A2 isolated from Bothrops moojeni snake venom, towards leukemic cells
Provedor de dados: 80

Abstract  Background: Chronic myeloid leukemia (CML) is a BCR-ABL1+ myeloproliferative neoplasm marked by increased myeloproliferation and presence of leukemic cells resistant to apoptosis. The current first-line therapy for CML is administration of the tyrosine kinase inhibitors imatinib mesylate, dasatinib or nilotinib. Although effective to treat CML, some patients have become resistant to this therapy, leading to disease progression and death. Thus, the discovery of new compounds to improve CML therapy is still challenging. Here we addressed whether MjTX-I, a phospholipase A2 isolated from Bothrops moojeni snake venom, affects the viability of imatinib mesylate-resistant Bcr-Abl+ cell lines.  Methods: We examined the cytotoxic and pro-apoptotic effect...

Comparação da eficiência de duas técnicas de coloração na detecção de cryptosporidi um em amostras fecais de duas espécies de jararacas mantidas em cativeiro
Provedor de dados: 195
Autores: Nascimento, Fernanda Gatti de Oliveira; Barbosa, Fernando Cristino; Rodrigues, Renata Dias; Pereira, Heloisa Castro; Gomes, Lara Reis; de Souza, Rafael Rocha.
Foi comparada a eficiência de duas técnicas de coloração, Ziehl-Neelsen modificado e Safranina modificada, para Cryptosporidium sp. em amostras fecais de duas espécies de Jararacas criadas em cativeiro. Cryptosporidium é um protozoário de carácter cosmopolita, oportunista, que acomete varias espécies, classificado dentro do filo Apicomplexa, e suas espécies parasitam as microvilosidades das células epiteliais do trato gastrointestinal. A localização desse protozoário caracteriza-se por ser intracelular, porém extracitoplasmático. Diferentemente de outros organismos, nos quais as infecções por Cryptosporidium são autolimitantes em indivíduos imunocompetentes, a criptosporidiose em répteis é frequentemente crônica e pode ser letal para serpentes. A...

The occurrence of Crepidobothrium sp. (Cestoda, Proteocephalidae) in Bothrops moojeni (Hoge) (Serpentes, Viperidae)
Provedor de dados: 104
Autores: Silva,Reinaldo José da; Karasawa,Andrea Satie Matsubara; Cherubini,André Luis; Barrella,Thomaz Henrique; Lopes,Carlos Alberto de Magalhães; Amarante,Alessandro Francisco Talamini.
The occurrence of Crepidobothrium sp.(Cestoda, Proteocephalidae) in the intestine of Bothrops moojeni (Hoge,1965)(Serpentes, Viperidae) is reported. The host snake was rescued from the fauna in Porto Primavera dam, Mato Grosso do Sul State, Brazil. The snake died in captivity on July 13,1999. At necropsy, 28 tapeworms were found in the snake intestine. The analysis of specimens morphology allowed the conclusion that they belong to the Crepidobothrium (Monticelli, 1900) genus. It was not possible to determine the Crepidobothrium species due to the lack of the gravid proglottids. This is the first report of B. moojeni as a host of cestodes.

Provedor de dados: 3
Autores: Canhas, Isabela Nascimento; Heneine, Luiz Guilherme Dias; Fraga, Thaís; Assis, Débora Cristina Sampaio de; Borges, Márcia Helena; Chartone-Souza, Edmar; Nascimento, Andréa Maria Amaral.
Toxins and venoms produced by living organisms have exhibited a variety of biological activities against microorganisms. In this study, we tested seven snake venoms from the family Viperidae for antibacterial activity and the activities of reversal of antibiotic resistance and inhibition of biofilm formation against 22 clinical isolates of Staphylococcus aureus. Bothrops moojeni venom exhibited anti staphylococcal activity with the lowest mean value of minimum inhibitory concentration (MIC). Moreover, reversal of antibiotic resistance was observed for combinations of B. moojeni venom (½ x MIC) and norfloxacin or ampicillin (both ½ x MIC) for 86.4% and 50% of the isolates, respectively. B. moojeni venom alone at ½ MIC inhibited 90% of biofilm formation,...

Digenetic trematodes infection in a Bothrops moojeni (Viperidae) population from a fauna rescue in Porto Primavera, São Paulo State
Provedor de dados: 45
Autores: Barrella,T.H.; Silva,R.J.
No presente estudo é descrita a infecção por trematódeos digenéticos parasitas da cavidade oral e esôfago em uma população de serpentes Bothrops moojeni provenientes de resgate de fauna em Porto Primavera, Estado de São Paulo. Foi observada prevalência de infecção de 68%. O grau de infecção (número de trematódeos por serpente) variou de 2 a 51 helmintos. Os trematódeos encontrados foram Ophisthogonimus spp. e Sticholecitha serpentis. A alta prevalência de infecção foi associada com a drástica alteração ambiental e o estresse multi-fatorial aos quais os animais foram submetidos, que poderiam ter favorecido o ciclo dos parasitas.
