Abstract: The automated teller machine (ATM) has been an important device in the banking sector and other financial institutions. The aim of this study was to isolate and identify Bacteria on the keypads of selected Automated Teller Machines (ATMs) in Makurdi metropolis. Swab sticks soaked with sterile normal saline were used to collect specimens from the keypads of the ATMs. The swab sticks were immediately transferred to the laboratory of Microbiology in the Department of Biological Science, Benue State University Makurdi. The collected samples were pooled into different tubes containing sterile normal saline and was agitated for 5minutes. This was further inoculated using the spread plate technique. The keypads of fifty (50) ATMs from five different locations in Makurdi were examined for bacterial contamination. The bacteria isolated from this study were, Staphylococcus aureus with a prevalence of (41.6%), Escherichia coli (34.4%) and Klebsiella pneumoniae (24.0%) on the keypads of the ATMs. There was a statistically significant relationship between the bacterial isolates and the respective locations (X2=72.96; df=8; p=0.000). This result gives the impression that ATMs could be a potential “pathogen city”. Therefore, adequate personal hygiene and regular routine cleaning of these machines bythe bank’s authorities is recommended.

Abstract: The technology based on the use of micro-organisms, in this case bacteria isolated from sites contaminated by industries, represents an alternative option for the treatment of wastewater before discharge into the environment. To this end, we carried out research in the city of Douala on the isolation, selection and identification of indigenous bacteria, potential for the bio-purification of effluents from a paint manufacturing industry located in the Logbaba industrial zone (Douala Cameroon). The bacteria were isolated from soils contaminated by effluents from the said industry. A programme of three selection tests in mineral saline liquid medium was implemented for the choice of isolates. The selection criterion was based on the growth of the isolates as assessed by OD measurement with a spectrophotometer (BIOBASE) at 600 nm. At the end of the selection process, 05 isolates (IS10, IS20, IS25, IS35 and IS41) were considered to be the best potential candidates for effluent bio-purification. On the basis of a pre-test identification completed by the API20E system, they were identified as Stenotrophomonas maltophilia (IS41); Pseudomonas luteola (IS20 and IS35); Pseudomonas fluorescens/putida (IS25) and Yersinia pseudotuberculosis (IS10) Exploiting the bio-purification capacities of these bacteria in the context of biological treatment of these polluting aqueous discharges could contribute to the preservation of the environment and human health. In the course of our further work, the bio-purification potential of these isolates will be evaluated.

Abstract: Root-knot nematodes (Meloidogyne spp.) are one of the most common vegetable diseases. In warm moist sandy soil, they are the most problematic and damaging. With about 5500 plant hosts, it is an economically important obligatory plant parasite. They have a significant impact on important crops around the world, such as vegetables, fruits, and cereal harvests. In most cases, nematode damage to crops is not easily visible, and it is often obscured by the many other factors that limit plant growth. Much of the harm produced by nematodes remains unnoticed or is mistaken for other reasons such fungal infection, water stress, or other physiological diseases, and by the time the disease is discovered, the damage to crops has already been done. A key hindrance to the preservation of vegetable crops is a lack of understanding among farmers about the challenges created by root knot nematodes, as well as ineffective management measures to tackle the threat. Except for a few investors, almost all Ethiopian farmers are unaware of the relevance of plant parasitic nematodes (PPNs). Plant parasitic nematodes not only have a direct impact on agricultural crops, but they also have an indirect impact by exposing the host plant to secondary infection and causing disease complexity in the affected plants. As a result, when compared to other infections, root knot nematode control is extremely challenging. As a result, farmers should receive training and awareness of PPN signs and assaults from the relevant body.
