Abstract

This study determined the seroprevalence, epidemiological factors and geospatial distribution of Brucella infection in indigenous breed of chicken in Yobe State, Nigeria. Random sampling was used in selecting the locations. Blood for serum were collected from 400 chickens in two Live Bird Markets and tested using mRBPT and SAT (EDTA). Coordinates of these markets were taken by a single click using a handheld GPS machine. Seroprevalence of 21.0% (mRBPT) and 18.0% (SAT-EDTA) from mRBPT positive samples were obtained which were not statistically significant based on locations (p>0.05). Seroprevalence by sex was 19.5% and 88.4% for male chickens using mRBPT and SAT-EDTA respectively and 21.8% and 84.6% for female chickens using mRBPT and SAT-EDTA respectively. There was no statistically significant difference in seropositivity by sex and test type (p>0.05). Adult chickens had seroprevalence of 20.5% and 84.5% using mRBPT and SAT-EDTA respectively while 20.8% and 100.0% were obtained in the young using mRBPT and SAT-EDTA respectively. There was no statistically significant difference in the seroprevalence by age (p>0.05). Geospatial map showed a distribution between 0.8% to 3.3% in the sampled areas. The study demonstrated infection by Brucella species in indigenous breed of chickens of both sexes and ages in Yobe state using mRBPT and SAT-EDTA. There is the need to create more awareness for stakeholders in the poultry industry in the State on the mode of transmission and prevention of the disease in order to reduce the menace that can be caused by the disease.

Key words: Seroprevalence, Brucella infection, epidemiological factors, geo-spatial mapping

UJMR News

The Editorial Board of UJMR is glad to have published the Twelfth edition (Volume 7 Number 1, June, 2022). The Journal covers general and Applied Microbiology, Biotechnology, Biological Sciences, Biochemistry, Bioinformatics, Medical, Public Health and Environmental sciences.

This year, UMYU Journal of Microbiology Research (UJMR) has reached its 5th year of publication which started in 2016. Over these years, many changes have been made to the typeface and general formats of the manuscripts, both the print version and online copies, to make the Journal meet the international standard and more visually appealing. From volume 3 (2) onward, all the online copies of UJMR papers on our website have been uploaded with their full colours. In addition, both authors and co-author are issued with e-certificates of publication for their respective published manuscripts.

We are glad that UJMR is gaining wider acceptance within Nigeria and in some foreign countries, and the number of submissions to the Journal is increasing. Despite the increase in manuscripts, UJMR maintained its quality as reflected by the rigorous peer-reviewing process. All articles submitted are accepted for publication based on a fair, objective, and anonymous assessment by our editors backed by the cogent decision by the editorial board. UJMR has thus increased the number of her associate editors by bringing in more people from academia who are experts in various fields within the scope of the Journal to enhance/maintain the speedy review of manuscripts received from various authors. The UJMR website has been upgraded so that UJMR readers and authors could get vital services such as online submission of manuscripts, downloading UJMR archives, author guidelines, etc.

UJMR’s vision is to be an internationally recognised premier journal of Microbiology, to contribute toward high-quality research and dissemination of UJMR to reach a larger audience worldwide. The journal is now indexed with reputable indexing organizations such as Crossref, Index Corpernicus International, International Institute of Organized Research (I2OR), Google Scholar, CiteSeerX, among others. In addition, the Journal has scored a publication impact factor of 2.525 for the year 2020 and Index Corpernicus value (ICV) of 85.02. Moreover, all our published articles are now assigned DOI. We hope that anyone with the expertise would join us and collaborate with our effort to obtain a much higher Impact Factor. We are delighted that UJMR is the first University-based microbiology journal in Nigeria. Therefore, we urge our academic colleagues to join hands with us towards projecting scientific research.

We appreciate the tireless efforts of the editorial board members, our editorial advisers, associate editors, and authors that contributed towards making UJMR a high-quality research journal. The support extended to the Journal by the Vice Chancellor and Umaru Musa Yar’adua University management is highly appreciated.
