Item type:Publication, Molecular survey of infectious bronchitis virus in commercial flocks in Macedonia reveals presence of different genotypes(COST - European Cooperation in science and technology, 2016-06); ; ; Introduction: Preliminary testing of commercial flocks using molecular and phylogenetic analysis revealed presence of genotypes QX and 4/91 in poultry farms with clinical signs and in poultry farms without clinical signs. Poultry farms are performing different vaccination programs without the knowledge of the genotype of the circulating strains. The purpose of this study was to detect presence of IBV in commercial flocks in Macedonia by molecular methods and to genotype the detected strains thus to establish a map of circulating genotypes in the country. Methods: Molecular survey was performed in 35 poultry farms representative for the whole territory of the country without clinical signs at different production age as part of active surveillance for avian influenza. From each farm 30 cloacal swabs were taken totalling 1050 samples. Samples were pooled by five in the laboratory. Additionally, samples (oropharyngeal swabs, affected organs) were taken from 15 farms with clinically signs (respiratory signs, drop in egg production, altered eqq quality) and post-mortem (respiratory, ovary and kidney lesions) findings associated to IBV. A real-time RT-PCR was performed targeting UTR region on all samples. A two-step nested RT-PCR was performed on all positive samples with primers targeting the S1 gene. Genotyping and subsequent phylogenetic analysis was performed by partial sequencing of the S1 gene region. Results: Results of the present study revealed presence of following genotypes of IBV’s circulating in commercial poultry in Macedonia: 4/91, Italy-02, QX, Mass, D274. This is first report of detection of Italy-02 in Macedonia. Conclusions: Establishing a map of circulating IBV genotypes will help towards better optimisation of vaccination protocol of poultry farms and will contribute towards better understanding of epidemiological situation on a country and regional level. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Application of Fluorescence Based Molecular Assays for Improved Detection and Typing of Brucella Strains in Clinical Samples(Faculty of Veterinary Medicine - Skopje, 2015-10-01); ; ; <jats:title>Abstract</jats:title> <jats:p> Bacteria from the genus Brucella are causative agents of brucellosis - a zoonotic disease which affects many wild and domestic animal species and humans. Taking into account the significant socio-economic and public health impact of brucellosis, its control is of great importance for endemic areas. The chosen control strategy could be successful only if adapted to the current epidemiological situation. This implies that a choice of appropriate diagnostic procedures for detection and typing of Brucella spp. strains are of essential importance. Significant advancement of molecular techniques and their advantages compared to classical methods, give strong arguments in promotion of these techniques as a powerful tool for comprehensive diagnostics of brucellosis. Considering this, the major tasks of the study were to select and implement molecular tests for detection and genotyping Brucella spp. and evaluate their performances using DNA from cultivated brucellae (islolates) and limited number of tissue samples from seropositive animals. The obtained results confirmed that implemented real time PCR for Brucella spp. detection, as well as MLVA-16 used for genotyping, have excellent analytical sensitivity (4.2 fg of Brucella DNA were successfully detected and genotyped). Furthermore, compared to bacteriological cultivation of Brucella spp., real time PCR and MLVA-16 protocols showed superior diagnostic sensitivity and detected Brucella DNA in tissues from which Brucella could not be cultivated. Based on the summarized study results, we propose a diagnostic algorithm for detection and genotyping of Brucella spp. bacteria. Routine use of proposed diagnostic algorithm will improve the effectiveness of infection confirmation and help for accurate evaluation of epidemiological situation.</jats:p> - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Molecular Detection of <i>Ehrlichia canis</i> in the Pet-Dog Population in R. N. Macedonia(Walter de Gruyter GmbH, 2021-06-01); ; Djadjovski, Igor<jats:title>Abstract</jats:title> <jats:p>Canine monocytic ehrlichiosis (CME) is a widespread, tick-borne, canine disease, caused by an obligate intracellular bacterium, <jats:italic>Ehrlichia canis</jats:italic>. The main vector, a brown-dog tick, <jats:italic>Rhipicephalus sanguineus</jats:italic>, is widely distributed, especially in areas with tropic, subtropic, or Mediterranean climates (Central and South America, Eastern and Western Asia, Africa, Australia and Southern Europe). The study performed in 2012, by Stefanovska et al., determined a seroprevalence of 18.7% of <jats:italic>E. canis</jats:italic> among the Macedonian dog population. Up to date, the presence of <jats:italic>E. canis</jats:italic>, using molecular diagnostic methods, has not been investigated in Macedonia. Therefore, this study aimed to confirm the presence of <jats:italic>E. canis</jats:italic>, in the pet-dog population on the territory of the city of Skopje, North Macedonia, using a highly sensitive multiplex Real-Time PCR method (qPCR). Whole blood samples from 80 dogs of different breeds and ages, with clinical symptoms of CME and positive serology result for the presence of antibodies against <jats:italic>E.canis</jats:italic>, were collected for analyses. Out of 80 dogs, 36 (45%) were found as positive. The present work reports the first molecular detection of <jats:italic>E. canis</jats:italic> in pet dogs on the territory of the city of Skopje, Macedonia.</jats:p> - Some of the metrics are blocked by yourconsent settings
