Summary: Clinical salmonellosis has been increasing significantly in Brazil, with a majority of strains demonstrating high rates of multi-drug resistance. The identification of a major Choleraesuis clonal group in several Brazilian states suggests closely related strains. This highlights the endemic nature of salmonellosis in key pig-producing regions in Brazil.

Summary: This study examined the effectiveness of vermicompost in controlling tomato bacterial canker and wilt disease. The addition of vermicompost in pot experiments reduced disease severity by 53.4% to 90.8%. In field experiments, vermicompost application led to a 66.6% reduction in disease severity. The findings suggest that vermicompost can be an important component in integrated pest and disease management.

Summary: This study evaluated the virulence factors and molecular characteristics of S. flexneri isolated from calves with diarrhea. Analysis showed that the isolates possessed typical biochemical characteristics of Shigella and were discriminated into different types using MLVA, PFGE, and MLST methods. The findings contribute to our understanding of S. flexneri and will aid in addressing clinical and epidemiological issues related to shigellosis.

Summary: In this study, a tomato BW detection model based on optimal spectral features was proposed. The results showed that infected and healthy tomatoes exhibit different spectral characteristics, with the spectral features of stems providing better accuracy for early detection of BW. The GA-SVM model achieved the best performance and its reliability was verified in a subsequent experiment.

Summary: Bacterial canker caused by Clavibacter michiganensis is a major vascular disease in tomato which currently lacks commercially available resistant cultivars. Through QTL-seq, a genomic region associated with bacterial canker resistance (Rcm6) was identified on chromosome 6 in the resistant cultivar Solanum lycopersicum Hawaii 7998. Further analysis revealed the Rcm6-9 genotype as an effective resistance allele with potential candidate genes for bacterial canker resistance.

Summary: In this study, a bacteria strain with high biocontrol potential, Bacillus velezensis (RC116), was identified and characterized for its ability to control tomato bacterial wilt and tomato Fusarium wilt. RC116 exhibited multiple biocontrol traits, including the production of enzymes, secretion of anti-microbial substances, and ability to degrade organophosphorus compounds. Pot experiments showed that RC116 had a biocontrol efficacy of 81% against tomato bacterial wilt.

Summary: This study elucidates that wilt-resistant tomatoes activate defense and growth processes simultaneously, while wilt-susceptible tomatoes undergo root senescence and reduction in root surface area following Ralstonia inoculation. Wilt-resistant tomatoes invest resources to promote both growth and defense, while wilt-susceptible tomatoes fail to grow during defense and ultimately succumb to infection.

Summary: Studies have shown that whole genome sequencing (WGS) has the highest resolution in distinguishing Salmonella enterica serovar Schwarzengrund strains compared to traditional methods like pulsed-field gel electrophoresis (PFGE), clustered regular interspaced short palindromic repeats (CRISPR), and multilocus sequence typing (MLST).

Summary: Bacteriophages have the potential to be promising alternative pesticides against bacterial diseases in crops. This study found that RpT1 and RpY2 phages effectively controlled bacterial wilt in tomato plants. The density, timing, and use of adjuvants of phages can influence their biocontrol efficacy.

Summary: The study found that co-infection with Ralstonia solanacearum and Fusarium oxysporum can reduce the severity of bacterial wilt disease in tomato plants, with bikaverin synthesis by Fusarium contributing to this effect. The arrival time of each microbe at the infection court also impacts the severity of wilt disease. Additionally, analysis of the root secretome in co-infection revealed previously uncharacterized secreted metabolites that inhibit the growth of R. solanacearum and provide protection against bacterial wilt disease in tomato seedlings.

Summary: In this study, the effect of Bacillus velezensis YYC on tomato plant growth and its ability to control bacterial wilt were investigated. Results showed that YYC promoted the growth of tomato plants and reduced the occurrence of bacterial wilt. It enhanced plant immunity by increasing the activity of defense-related enzymes and induced the expression of genes involved in plant resistance to pathogens. This study provides insights into the mechanisms of growth promotion in tomato plants and suggests the potential use of B. velezensis YYC as a biological fertilizer.

Summary: This study evaluated the effects of wheat straw biochar on disease development, plant physiology, and proteomic expression in tomato plants infected with Ralstonia solanacearum. The results showed that biochar application improved plant growth, reduced disease severity, and decreased the colonization of R. solanacearum in tomato stems. Physiological analysis revealed that biochar treatment increased peroxidase and lipoxygenase activities, as well as the content of total soluble phenolics and lignin-like phenolic polymers in tomato leaves. Proteomic analysis showed that biochar treatment upregulated genes involved in lignin synthesis, anion channel and sulfur metabolism, and downregulated genes involved in microtubule and cytoskeleton organization, as well as UDP-glucose metabolism.

Summary: This study isolated six Streptomyces-like strains with high antagonistic activities against Ralstonia solanacearum, and found that the mixed strain (NEAU-D18 + NEAU-88) showed better control efficacy for tomato bacterial wilt than single strains. The mixed strain was demonstrated to be a potential biocontrol agent for reducing disease incidence and yield loss.

Summary: Soil microbial communities play a crucial role in ecosystem functions, but understanding the complex nature of the microbial world and leveraging positive interactions for environmental benefits remains challenging. In this study, we investigated soil bacterial communities in healthy and diseased tomatoes and found that disease samples had higher abundance of a pathogen and lower bacterial diversity. Healthy tomato rhizosphere harbored more plant-beneficial microbes and had a more complicated co-occurrence network, suggesting better adaptability to soil-borne pathogen invasion. Community assembly analysis showed that the healthy rhizosphere communities were less phylogenetically clustered and mainly driven by dispersal limitation, while the diseased rhizosphere communities were primarily shaped by homogeneous selection. These findings highlight the importance of soil bacterial community composition and assembly in responding to soil-borne pathogen invasion.

Summary: Xanthomonas citri subsp. citri is a major plant pathogen that causes bacterial citrus canker, resulting in substantial economic losses to the citrus industry. Genomic sequencing has provided insights into the evolutionary relationships and distinct pathotypes of X. citri subsp. citri. The core-genome multilocus sequence typing (cgMLST) scheme described in this study will be a valuable resource for studying the epidemiology and evolution of this plant-pathogenic bacteria.

Summary: Adverse storage conditions can lead to the deterioration of grain quality by promoting the growth and spread of fungi. Antifungal biopreparations, such as Lactobacillus species, show potential in preserving grain quality and inhibiting the growth of pathogenic fungi. Further research is needed to understand the efficacy of LAB in different storage conditions and against various phytopathogenic fungi.
