Three methods were used for the recovery of mycobacteria from blood specimens obtained from acquired immunodeficiency syndrome patients: (i) inoculation of 7H11 agar plates with a concentrated specimen, (ii) inoculation of 7H12 BACTEC vials with a concentrated specimen, and (iii) inoculation of 7H13 BACTEC vials with a nonconcentrated specimen. In this study, we examined 255 specimens and obtai...
Decontamination studies investigating the effectiveness of products and processes for the inactivation of Bacillus species spores have traditionally utilized metering viable spores in a liquid suspension onto test materials (coupons). The current study addresses the representativeness of studies using this type of inoculation method compared to when coupons are dosed with a metered amount of ae...
By ultracentrifugation of 30 ml of highly dilute suspensions of herpes simplex virus (HSV) directly onto monolayer cultures grown in centrifuge tubes, infectivity was significantly greater than without centrifugation. Ultracentrifugation at 20,000 to 25,000 rpm (28,000 to 45,000 X g) for 1.5 to 2.3 h was utilized with good preservation of cultures. With low-speed centrifugation at 3,000 rpm (1,...
Inoculation theory, a theory of conferring resistance to persuasive influence, has established efficacy as a messaging strategy in the health domain. In fact, the earliest research on the theory in the 1960s involved health issues to build empirical support for tenets in the inoculation framework. Over the ensuing decades, scholars have further examined the effectiveness of inoculation-based me...
1. Titration and neutralization of the Western strain of equine encephalomyelitis virus can be carried out in vitro by means of tissue culture. 2. The in vitro titration test as presented is a more sensitive method than animal inoculation. 3. Tissue culture may be better than animal inoculation for the detection of small amounts of virus. 4. The neutralization obtained in tissue culture is 100 ...
Closed Circuit Television (CCTV) operators are responsible for maintaining security in various applied settings. However, research has largely ignored human factors that may contribute to CCTV operator error. One important source of error is inattentional blindness--the failure to detect unexpected but clearly visible stimuli when attending to a scene. We compared inattentional blindness rates ...
We investigated the fungal entomopathogens Beauveria bassiana and Metarhizium anisopliae to determine if endophytic colonization could be achieved in cassava. An inoculation method based on drenching the soil around cassava stem cuttings using conidial suspensions resulted in endophytic colonization of cassava roots by both entomopathogens, though neither was found in the leaves or stems of the...
—Field inoculation trials are an important component of screening American elms (Ulmus americana) for levels of resistance to Dutch elm disease. A major concern in screening is variability in disease ratings from year to year. Previous studies have demonstrated that timing of inoculation can have a significant impact on disease susceptibility. In this study, trees were inoculated in the main st...
