BackgroundBovine tuberculosis (bTB) is an important bacterial infectious disease in Albania of concern to animal and human health; its prevalence is poorly documented.MethodsIn this longitudinal study, we tested by ELISA 2661 serum samples, from 154 herds, with the aim of establishing the suitability of this approach to screen the bovine population for bTB. In a follow-on survey of 87 animals in three villages, we assessed the usefulness of the Mycobacterium bovis IDEXX ELISA (IDEXX M. bovis Antibody (Ab) Test. IDEXX Europe B.V P.O. Box 1334, 2130 EK Hoofddorp, The Netherlands) assay by comparing IDEXX results with the results of the single intradermal cervical skin test. Skin tests were performed either after or at the time of collection of blood samples, and therefore cattle were not sensitized by tuberculin before serological testing.ResultsThe proportion of herds in which serologically positive cattle were found was 18.2 % (95 % CI, 1.9–25.8 %) and the prevalence of seropositive cattle was 1.4 % (95 % CI, 0.8–2.1 %). In the follow-up study, two of the 87 animals reacted positively to the skin test and two produced inconclusive reactions. No overlap was found between the four animals with positive IDEXX ELISA results and the four animals with non-negative skin test results.ConclusionThe lack of agreement between the results of the two tests may reflect different elements of the immune response (humoral and cell-mediated immunity). In future, cattle should be sensitized by the intradermal injection of tuberculin 14 days prior to the collection of blood samples, which would then be tested by the Mycobacterium bovis IDEXX ELISA Test in order to determine more accurately the prevalence of infection.

The current research goal is to identify the degree of crystallized intelligence, to identify personality traits (responsibility, emotional balance, Self-Discipline, sociality) among students in the preparatory stage, the significance of the differences in the variables of the research is accordingly to the gender and specialization variable, and to identify the strength and direction of the relationship between crystallized intelligence and personality traits. The sample was of 400 students (males and females). The researchers used two tools: Test of crystallized intelligence for Dr.Kamal Ibrahim Morsi 2001 and personal traits measurement, Prepared by the researchers, The appropriate statistical tools available in the statistical package (Spss) were used. Several results found in this study:1. weakness in the crystalized intelligence of the preparatory stage students with statistical significance by (0.5) As for gender and specialization variables, there were statistically significant differences between the variable of specialization and the scientific interest, while there were no differences in the gender variable.
