Summary: A novel bacterial strain, designated S2(T), belonging to the genus Aquabacterium, was isolated from soil in South Korea. The strain showed low sequence similarity and DNA-DNA hybridization values with phylogenetically related taxa. The genomic analysis revealed the presence of multiple putative biosynthetic gene clusters involved in secondary metabolite production.

Summary: In this study, a polyphasic taxonomic approach was used to characterize a Gram-stain-positive bacterium isolated from soil in a maize field in Taiwan, which was named Aeromicrobium terrae. Analyses based on phylogeny, phenotypic traits, chemotaxonomic characteristics, 16S rRNA gene sequences, and ANI values supported the proposal of this bacterium as a novel species within the genus Aeromicrobium.

Summary: This study identified a novel group of 26 Acinetobacter strains (T24) forming a distinct clade within the genus based on core genome phylogenetic analysis. The strains exhibited differences in carbon source assimilation tests and led to the proposal of two new species, Acinetobacter terrae and Acinetobacter terrestris, associated with terrestrial ecosystems.

Summary: This study determined the presence of diarrhoeagenic Escherichia coli (DEC) and Extended Spectrum Beta-Lactamase-Producing Enterobacteriaceae (ESBL-PE) and their antimicrobial resistance patterns among diarrhoea patients in two healthcare facilities in Ghana. The findings showed that the high prevalence of ESBL-PE strains among stool isolates limits the treatment options for diarrhoeal patients, highlighting the importance of routine laboratory testing and strengthened surveillance systems in healthcare facilities.

It identified 88 cases of CCHF, including 13 fatalities, with the majority concentrated in the Kordofan region. The study calls for the establishment of a genomic-based integrated One Health surveillance and response system.

Summary: This study aimed to investigate integrated One Health studies on foodborne illnesses in the Middle East and determine the prevalence, serovars, and antimicrobial resistance phenotypes and genotypes of Salmonella and Campylobacter strains. The results showed that the One Health approach was not rigorously applied in the Middle East countries, and there was an uneven distribution in the reported data between the countries.

Summary: Pastoralists in the Somali Regional State have a negative attitude towards wildlife, considering them as a threat to livestock. Although they have daily encounters with wildlife, most of them do not believe that wildlife can transmit diseases to livestock. They generally dislike wildlife and do not see any benefits in protecting them. Wildlife populations have decreased in the past decade, which has implications for conservation efforts.

Summary: Agriculture, particularly livestock production, is crucial for livelihoods in sub-Saharan Africa. Lack of control of infectious diseases significantly affects livestock productivity and rural populations. This scoping review found that vaccination is the most effective and profitable method for controlling infectious livestock diseases in the region. However, implementation of vaccination programs must address field challenges such as pathogen surveillance and optimal vaccine delivery tools.

Summary: Resistance to antibiotics is a pressing global public health concern and has significant impacts on health and the economy. Despite joint research efforts, the spread of antimicrobial resistance (AMR) between humans, animals, and the environment remains unclear. This systematic review aims to examine the current understanding of AMR acquisition, diversity, and interspecies spread.

Summary: This study examined the antibacterial effect and mechanism of action of iodinated X-ray contrast agents and complexed lanthanide MRI contrast solutions on six different microorganisms. Bacteria were exposed to media containing contrasting agents at different concentrations and pH levels for varying durations. The antibacterial effect was further tested using agar disk diffusion analysis and the microdilution inhibition method. Bactericidal effects were observed at low concentrations and low pH, specifically for Staphylococcus aureus and Escherichia coli.

Summary: Animal tuberculosis is widespread in Nigeria, but active surveillance and control measures are lacking. This study conducted a comprehensive meta-analysis to assess the distribution of tuberculosis in animals and analyze potential factors in Nigeria. The overall prevalence of tuberculosis was 7% and it was found in cattle, goats, sheep, camels, and wildlife. The occurrence of infection was significantly influenced by publication period, geographical location, sample size, and detection methods.

Summary: This study investigated the microbial quality and antimicrobial resistance of bacteria found in Ready-to-Eat (RTE) food, water, and palm swab samples. The samples were collected from food vending sites in Accra, Ghana, between 2019 and 2020. The results showed the presence of various bacteria species in the samples, with some showing resistance to commonly used antibiotics. The study also highlighted the high levels of bacterial contamination in RTE food and water, indicating their unsafe condition. The findings emphasize the need for continuous surveillance in the food industry and the enforcement of food safety laws in Ghana.
