BackgroundThe prevalence of bovine tuberculosis (BTB) in dairy cattle in the three major milk producing regions of Eritrea was assessed by subjecting 15,354 dairy cattle, 50 % of Eritrea’s dairy cattle population, to the single intradermal comparative tuberculin test (SICTT). Skin test results were interpreted according to guidelines of the World Organization for Animal Health (OIE) with >4 mm as cutoff in skin thickness increase. In addition, we studied the relation between ‘physiological’ variables related to pregnancy and lactation, and the variable ‘region’ on the probability to be skin test positive.ResultsThe BTB prevalences at animal and herd levels were: 21.5 % and 40.9 % in Maekel, 7.3 % and 10 % in Debub, and 0.2 % and 1.6 % in the Anseba region, respectively. Overall, in the regions included, prevalence was 11.3 % (confidence interval (CI) 95 % CI, 11.29 – 11.31 %) and 17.3 % (95 % CI, 17.27–17.33 %), at animal and herd level, respectively. Considering positive herds only, the animal BTB prevalence was 36.8 %, 30.1 %, and 1.8 %, in Maekel, Debub and Anseba, respectively, and the overall animal prevalence within these herds was 32 %. In adult dairy cattle the probability of positive reactivity in the SICTT test was highest in pregnant animals as compared to the other categories.ConclusionThis study reports persistent prevalence of BTB as defined by positive SICTT in the dairy sector of Eritrea, especially in the regions of Maekel and Debub that are located in the central highlands of the country. To our understanding this is the first report that has encompassed all the major dairy farms in Eritrea and it will be instrumental in advocating future BTB control programs in the dairy sector.Electronic supplementary materialThe online version of this article (doi:10.1186/s12917-016-0705-9) contains supplementary material, which is available to authorized users.

Background There is limited information about the psychosocial sub-determinants regarding the use of HIV Testing and Counselling (HTC) services among suspected Tuberculosis (TB) patients in Sudan. This study aimed to assess the association between psychosocial beliefs and the intention to use HTC services and to establish the relevance of these beliefs for developing behaviour change interventions among suspected TB patients. Methods Suspected TB patients (N = 383) from four separate TB facilities completed a cross-sectional questionnaire which was based on the Reasoned Action Approach theory. Eligibility criteria included attending Tuberculosis Management Units in Kassala State as suspected TB patients and aged 18–64 years. A Confidence Interval Based Estimation of Relevance (CIBER) analysis approach was employed to investigate the association of the beliefs with the intention to use HTC services and to establish their relevance to be targeted in behaviour change interventions. Results The CIBER results showed the beliefs included in the study accounted for 59 to 70% of the variance in intention to use HTC services. The belief “My friends think I have to use HTC services” was positively associated with the intent to use HTC, and it is highly relevant for intervention development. The belief “I would fear to be stigmatized if I get a HIV positive result” was negatively related to the intention to use HTC services and was considered a highly relevant belief. The belief “If I use HTC services, health care providers will keep my HIV test result confidential” was strongly associated with the intention to use HTC services. However, the relevance of this belief as a target for future interventions development was relatively low. Past experience with HTC services was weakly associated with the intention to use HTC services. Conclusion The intention to use HTC was a function of psychosocial beliefs. The beliefs investigated varied in their relevance for interventions designed to encourage the use of HTC services. Interventions to promote intention to use HIV testing and counselling services should address the most relevant beliefs (sub-determinants). Further study is needed to establish the relevance of sub-determinants of the intention to use HTC services for interventions development.

Background: There is limited information about the psychosocial (sub-) determinants regarding the use of HIV Testing and Counselling (HTC) services among Tuberculosis(TB) suspected patients in Sudan. This study aimed to assess the psychosocial beliefs related to the intention to use HTC services among TB suspected patients and to establish the relevance of these beliefs for developing behaviour change interventions. Methods: TB suspected patients (N= 383) completed a cross-sectional questionnaire from four separate TB facilities. The questionnaire was based on the Reasoned Action Approach theory. Eligibility criteria included attending Tuberculosis Management Units in Kassala State as suspected TB patients and aged 18-64 years. A Confidence Interval Based Estimation of Relevance (CIBER) analysis approach was employed to investigate the effects of the beliefs on the intention to use the HTC services and to establish their relevance to be targeted in behaviour change interventions. Results: The CIBER results showed the beliefs included in the study accounted for 59% to 70% of the variance in intention to use HTC services. The belief "My friends think I have to use the HTC services" was positively associated with the intent to use HTC, and it is highly relevant for interventions. The belief “If I would fear to be stigmatized if I get HIV positive result" was negatively related to the intention to use the HTC services and highly relevant belief. The belief “If I use HTC services, the health care providers will keep my HIV test result confidential" was strongly associated with the intention to use HTC services. However, it was not a very low relevant belief. Past experience with HTC services was weakly associated with the intention to use HTC services. Conclusion: The intention to use HTC was a function of psychosocial beliefs. The belief investigated varied in their relevance for interventions designed to encourage the use of HTC services. Interventions to intention to use HIV testing and counselling services should address the most relevant beliefs (sub-determinants). Further study is needed to establish the relevance of sub-determinants of the intention to use HTC services.
