The practice of vending water in plastic jerry cans for domestic use has become a major source of household drinking water in Zaria due to inadequate pipe-borne water. The unhygienic practice of the water vendors and poor sanitary condition of the jerry cans and the water sources are of public health concern. Accordingly, this research was conducted to examine the bacteriological quality of vended water from jerry cans in Zaria city, Kaduna state, Nigeria. Water samples from five different vendors from twenty different locations were collected and used for isolation and enumeration of bacterial loads. The isolation and biochemical characterizations of the isolates revealed the presence of seven genera represented by eight bacterial species namely: Escherichia coli, Proteus mirabilis, Salmonella typhi, Klebsiella pneumoniae, Corynebacterium sp, Proteus vulgaris, Citrobacter freundi and Bacillus subtilis. Escherichia coli is the most predominant bacterial species among the vended water samples (44.44%) followed by S. typhi (18.52%) while Proteus mirabilis, Corynebacterium sp and Citrobacter freundi are the least prevalent with 3.70%.  Most of the identified bacterial species in the samples were pathogenic. More so, the bacterial loads associated with the jerry cans water ranged between 1.0x106–8.0x106 CFU/mL from the plates count which is above WHO standard limit of ˂1.0x101 CFU/mL. It was therefore inferred that the bacterial counts associated with the jerry cans can pose public health risk. Proper sanitation and orientation on personal hygiene to the vendors are urgently needed.

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.
