13. Translocation of Co and Mo applied in different times in soybeans / Translocação de Co e Mo aplicados em diferentes épocas na cultura da soja
This study evaluated the translocation of Co and Mo applied in different times on the development of soybeans, determining their presence in soybean root nodules, leaves and grains. The assay was done in Fazenda Canadá, located in Uberlândia, MG. The experimental design was randomized blocks with seven treatments and six repetitions. Each experimental unit

15. DOSES, AMBIENTE E FORMA DE INFECÇÃO CAUSADA POR Fusarium solani f.sp. chrysanthemi EM CRISÂNTEMO (Dendranthema grandiflora) cv. CALABRIA E SEU CONTROLE POR Trichoderma virens / DOSES, ENVIRONMENT AND FORMS OF INFECTION OF Fusarium solani f. sp. chrysanthemi IN CHRYSANTHEMUM (Dendranthema grandiflora) cv. CALABRIA AND ITS CONTROL BY Trichoderma virens
Fusarium wilt has been damaging the chrysanthemum crop in the central region of Rio Grande do Sul, especially in those cultivated in greenhouse. Four experiments were done with the objective of studying the effect of doses, environment, and forms of infection of Fusarium solani f. sp. chrysanthemi in chrysanthemum and its control by Trichoderma virens. In th

16. Wide Variations in Herpes Simplex Virus Type 1 Inoculum Dose and Latency-Associated Transcript Expression Phenotype Do Not Alter the Establishment of Latency in the Rabbit Eye Model
The latency-associated transcript (LAT) is required for efficient reactivation of herpes simplex virus type 1 from latent infection in the rabbit eye model, but LAT's mechanism of action is unknown. In addition to reactivation, the LAT region seems to correspond to multiple functions, with some LAT deletion mutants exhibiting increased virulence, increased n

17. Efficacy of orally administered penicillin V for prophylaxis of experimentally induced streptococcal endocarditis.
Four oral penicillin V regimens were compared for the ability to prevent Streptococcus sanguis infection of experimentally induced valvular heart lesions in rabbits. Challenge doses of 10(4), 10(6), and 10(8) CFU of a penicillin-susceptible strain of S. sanguis were used in this study. Measured by recovery of test organisms from endocardial lesions, the lowe

18. Tolerance and efficacy of parenterally administered penicillin-streptomycin and orally administered amoxicillin or penicillin V for prophylaxis of experimentally induced streptococcal endocarditis.
A regimen of a single intramuscular dose of penicillin G-streptomycin was compared with regimens of three oral doses of amoxicillin and two oral doses of penicillin V to prevent Streptococcus sanguis endocarditis in rabbits with experimentally induced valvular heart lesions. Challenge doses of 10(4), 10(6), and 10(8) CFU of a strain of S. sanguis highly tole

19. Determination of the In Vivo Pharmacodynamic Profile of Cefepime against Extended-Spectrum-Beta-Lactamase-Producing Escherichia coli at Various Inocula
Cefepime was evaluated in vivo against two inoculum sizes of four strains of Escherichia coli that produced extended-spectrum beta-lactamases (ESBLs) in a murine neutropenic thigh infection model to characterize the pharmacodynamic activity of cefepime in the presence of ESBL-producing bacteria and to evaluate if differences in lengths of cefepime exposure a

20. Relationship Between Gentamicin Susceptibility Criteria and Therapeutic Serum Levels for Pseudomonas aeruginosa in Mouse Infection Model
In this study estimations of in vivo and in vitro gentamicin susceptibility for a series of strains of Pseudomonas aeruginosa were compared. The series included an extremely susceptible strain, typically susceptible strains by current susceptibility criteria, and strains with enzymatic and permeability-mediated resistance. In vivo testing was done by using a

21. Comparative capacity of orally administered amoxicillin and parenterally administered penicillin-streptomycin to protect rabbits against experimentally induced streptococcal endocarditis.
A single-intramuscular-dose immunization regimen with a penicillin G-streptomycin combination was compared with three oral-dose amoxicillin regimens for the capacity to prevent Streptococcus sanguis infections of experimentally induced valvular heart lesions in rabbits. Challenge doses of 10(4), 10(6), and 10(8) CFU of a strain of S. sanguis equally suscepti

22. Optimal times above MICs of ceftibuten and cefaclor in experimental intra-abdominal infections.
The duration of time that serum drug levels remain above the MIC (time above the MIC) for the pathogen has been shown to be the most significant parameter determining the efficacies of beta-lactam antibiotics. In the described study, we investigated the optimal time above the MIC of ceftibuten and cefaclor using a nonneutropenic mouse model of intra-abdomina

23. Inoculum effect with chloroquine and Plasmodium falciparum.
In the studies reported here, we examined the inoculum effect observed with chloroquine and Plasmodium falciparum. The 50% effective doses observed with both chloroquine-susceptible and -resistant parasites increased five- to sevenfold from their baseline values as the inoculum was increased from 2 X 10(5) to 2 X 10(7) parasitized erythrocytes per ml (parasi

24. Effect of sublethal concentrations of four chemicals on susceptibility of juvenile rainbow trout (Oncorhynchus mykiss) to saprolegniosis.
The effects of sublethal concentrations of a variety of chemicals on the susceptibility of rainbow trout (Oncorhynchus mykiss) juveniles to Saprolegnia parasitica infection was examined. Sublethal concentrations of un-ionized ammonia (0.05 mg/liter) and nitrite (0.12 mg/liter) increased fish susceptibility after 10 days of exposure to the toxin, this increas
