Behavior of Bradyrhizobium japonicum strains under different herbicide concentrations
Provedor de dados: 87
Autores: Arruda,J.S.; Lopes,N.F.; Moura,A.B.
The Bradyrhizobium japonicun strains SEMIA 5073, SEMIA 5074, SEMIA 5079 and SEMIA 5080 were grown in vitro using Vincent medium combined with different rates of the herbicides imazaquin (0, 0.04, 0.12, 0.24, 0.36 mg a.i. g-1), clomazone (0, 0.4, 0.8, 1.6 and 3.2 mg a.i. g-1) and sulfentrazone (0, 0.2, 0.4, 0.8 and 1.6 mg a.i. g-1) to evaluate the strains tolerance to herbicides. The three herbicides drastically inhibited all the rhizobium strains tested, showing a significant decrease of the CFU number as a function of herbicide rates. The rhizobium strains presented a differentiated tolerance to the herbicides. The herbicide rates that reduced 50% (I50) of the growth or survival of the rhizobium strains were below the recommended sprayed rates for weed...

Avaliação da eficácia do fipronil em Rhipicephalus (Boophilus) microplus em tratamentos consecutivos
Provedor de dados: 45
Autores: Souza,A.P.; Paim,F.; Bellato,V.; Sartor,A.A.; Moura,A.B.; Rosa,L.D.; Miquelluti,D.J.
A realização deste trabalho teve como objetivo avaliar a eficácia do fipronil em Rhipicephalus (Boophilus) microplus, durante e após 14 tratamentos, no período de dezembro de 2006 a abril de 2009. O experimento foi realizado em uma propriedade rural do município de Lages, SC, utilizando-se 20 bovinos mestiços charolês mantidos em campo nativo, naturalmente infestados com R. (B.) microplus. A cada 14 dias, foram realizadas contagens das fêmeas de carrapato, maior ou igual a 4,5mm. Os animais foram tratados com fipronil 1mg/kg via pour on, quando a média do número de carrapatos foi igual ou superior a 40 fêmeas. Ao final do experimento, para análise da eficácia do fipronil 1%, foi realizado o teste de estábulo, utilizando 10 animais infestados com larvas...

Toxoplasma gondii in milk of naturally infected dairy ewes on west mesoregion of Santa Catarina state, Brazil
Provedor de dados: 45
Autores: Ossani,R.A.; Borges,H.A.T.; Souza,A.P.; Sartor,A.A.; Miletti,L.C.; Federle,M.; Moura,A.B.
ABSTRACT This study aimed to detect Toxoplasma gondii in the milk of dairy sheep in the Western mesorregion of state of Santa Catarina by bioassay (22 milk samples from eight ewes seropositive; IFA ≥256) and PCR [for the detection of agent in the brains of mice inoculated on bioassay and directly from milk (108 samples from 42 seropositive ewes (IFA, ≥64) in different lactation periods)]. T. gondii DNA was detected in mice brains inoculated with milk from eight sheep (a sample of the 45th day of lactation and seven in the collection of 90th day) and directly from the milk in samples of the second collection (90 days) in five animals. Taking into account both assays, from a total of 42 ewes in lactation and seropositive for T. gondii, 30.95% (13/42) of the...

Genotyping of Toxoplasma gondii isolates from naturally infected Gallus domesticus in Santa Catarina state, Brazil
Provedor de dados: 45
Autores: Trevisani,N.; Barros,L.D.; Vieira-Neto,A.; Sartor,A.A.; Souza,A.P.; Garcia,J.L.; Moura,A.B.
ABSTRACT Toxoplasmosis is a widespread zoonosis that can infect warm-blooded animals including birds and humans, and chickens are considered to be indicators of environmental contamination. In Brazil, Toxoplasma gondii has a non-clonal population structure composed of three lineages (I, II, and III), presenting high recombination, and resulting in wide genetic diversity. This study aimed to genetically characterize T. gondii isolates from naturally infected chickens (Gallus domesticus) in Santa Catarina state, southern Brazil region. Sera from 133 free-range chickens were analyzed by an immunofluorescence assay (IFA) to detect IgG antibodies against T. gondii. Brain and heart from 30 positive animals, based on IFA (≥ 1:64), were used to isolate the...

Antibodies against rickettsiae from spotted fever groups in horses from two mesoregions in the state of Santa Catarina, Brazil
Provedor de dados: 45

Bacteria of the Rickettsia genus are agents of Brazilian Spotted Fever (BSF), a zoonotic disease which is difficult to diagnose, evolves quickly and can result in death. Antibodies against Rickettsia spp. in horses were studied, by means of Indirect Immunofluorescence Assay (IFAT ≥64), in 150 blood samples taken from animals in two Santa Catarina mesoregions (Planalto Serrano and Vale do Itajaí). The overall occurrence of Rickettsia spp. antibodies in horses was 18.66%, with cross-reactivity occurring in all positive samples for at least two of the species tested. Separately, according to the species, 25 (16.66%) samples were positive for R. rickettsii, 15 (10%) for R. parkeri, 22 (14.66%) for R. amblyommii, 23 (15.33%) for R. rhipicephali, 16 (10.66%) for...
