Elimination of Salmonella Senftenberg W775 bacteria in the cultivation of some agricultural crops

Badania prowadzono w latach 2005-2006 na terenie Stacji Badawczej w Mochełku, należącej do Uniwersytetu Technologiczno-Przyrodniczego w Bydgoszczy. Ich celem było określenie stopnia przeżywalności oraz tempa inaktywacji bakterii wskaźnikowych Salmonella Senftenberg W775 w glebie w zależności od uprawy wybranych roślin rolniczych. W eksperymencie rolę nośnika pałeczek Salmonella Senftenberg W775 pełnił kompost z odpadów komunalnych, który wprowadzono do środowiska glebowego na poletkach doświadczalnych w uprawach rolniczych owsa, mieszanki owsa z łubinem żółtym, żyta jarego oraz mieszanki żyta jarego z łubinem żółtym. Przeprowadzone badania wykazały, że tygodniowe tempo eliminacji Salmonella Senftenberg W775 w glebie, w zależności od poszczególnych upraw polowych, przyjmowało wartość od 0,33 do 0,46 log, natomiast maksymalny czas przeżycia wykrywanych drobnoustrojów wynosił od 18 do 24 tygodni.The aim of the present research was to determine the survival rate and the rate of inactivation of indicator bacteria Salmonella Senftenberg W775 in soil, depending on the cultivation of selected agricultural crops. The research was carried out over 2005-2006 at the UTP Experimental Station at Mochełek. In the experiment the role of the carrier of Salmonella Senftenberg W775 bacilli was played by communal waste compost introduced into the soil environment, on experimental plots with agricultural plantation of oat, mixture of oat with yellow lupine, spring rye and a mixture of spring rye with yellow lupine. The present research demonstrated that the weekly elimination rate of Salmonella Senftenberg W775 in soil, depending on respective field crops, ranged from 0.33 to 0.46 log, while the maximum survival time of detectable microorganisms – from 18 to 24 weeks

The scales most commonly used by the therapeutic team for assessment of a patient with traumatic brain injury (TBI) include deficit scales, functional scales, and scales assessing quality of life. The purpose of this study was to establish the relationships between the particular scales used for assessment of patients with TBI.Methods: This multicenter study included 159 patients with TBI. The direct observation technique was used. Two measurements were made (at hospital admission and discharge) using standardized assessment scales, ie, the Glasgow Coma Scale (GCS), the Functional Capacity Scale (FCS), the Functional Index “Repty” (FIR), and the Glasgow Outcome Scale.Results: Patients with mild impairment of consciousness were most numerous in the examined group at both admission and discharge, ie, 118 (78.8%) and 134 patients (89.3%), respectively. The mean score for functional capacity measured with the FCS was 34.41 points (71.7%) on the day of admission and 41.87 points (87.2%) on the day of discharge from hospital. A significant correlation was found between results obtained using the GCS and results on the FIR, on both the day of admission [R t(n-2) =7.612=0.530; P=0.00] and the day of discharge [R t(n-2) =8.998=0.595; P=0.00]. Further, a high correlation was found between the FCS and the FIR (rs= -0.854 on day of admission and rs= -0.840 on day of discharge).Conclusion: The majority of examined patients had mild impairment of consciousness. A moderate correlation was found between the GCS and the scales assessing activities of daily living. A high correlation was found between FCS and FIR, which may result from the similarities between the analyzed tools in the scope of their construction and application.Keywords: head trauma, assessment tools, numeric scale
