RESUMEN
Background: Brucellosis is one of the most important zoonotic diseases caused by Gram-negative bacteria belonging to the genus Brucella. Detection of Brucella species in different countries is of utmost importance. Aims: This study aimed to detect Brucella abortus and Brucella melitensis in domestic ruminant blood samples and their ticks in western Iran. Methods: Sampling was conducted on ruminants from August to September 2020 in four different counties of Kurdistan Province, including Divandareh, Marivan, Baneh, and Sanandaj. Totally, 250 blood samples were collected from 250 small ruminants. There were no ticks on the skin of six (2.4%) ruminants, and 244 ticks were isolated from 244 animals. After genomic DNA extraction from all the collected samples, quantitative polymerase chain reaction (qPCR) was performed to detect IS711 gene. Results: Based on qPCR results, Brucella genus was detected in two blood samples (0.8%) from female sheep and four ticks (1.6%) from male sheep, including three Dermacentor marginatus (1.22%) and one Rhipicephalus turanicus (0.4%). Although B. melitensis was not detected in any tick or blood sample, one tick sample (D. marginatus) was positive for B. abortus. Conclusion: Considering the positivity of ticks for brucellosis in this study, there is a possibility of Brucella transmission from infected ticks to humans and animals through tick bites, nevertheless, in order to identify the Brucella transmission relationship between ticks and animals, serological tests should be used in future studies.
RESUMEN
Authority, in learning situations, has been widely defined as the role of teacher, or parents, ignoring the person by whom knowledge is delivered. This research was carried out to examine the influence of this type of authority on the relations between students' beliefs and their judgments of content. 160 Iranian college students were randomly divided into two equal groups. Then, both groups were assessed for their beliefs about sources of values. In the next step, two scenarios of the same content were distributed to the two groups; one scenario was attributed to a highly respected religious person in Islam and another to a famous nonreligious psychoanalyst. College students then were asked to judge the ideas proposed in the content. Analysis showed that the relations between students' beliefs and their judgments were different for the two groups. Pending confirmation by further study, some educational recommendations may be offered.
