Summary: Bacterial keratitis is a common type of infectious keratitis, and the spectrum of pathogenic bacteria and their drug susceptibility varies among different regions. A meta-analysis was conducted to review the global culture rate, distribution, trends, and drug susceptibility of bacterial isolates from bacterial keratitis over the past 20 years. The most common bacteria were Staphylococcus spp., Pseudomonas spp., Streptococcus spp., Corynebacterium spp., and Moraxella spp. The analysis also revealed differences in antibiotic susceptibility among different bacteria types.

Summary: A label-free sensing method has been developed to identify hazardous pathogens based on their intrinsic properties. By performing a thermal curve analysis with terahertz metamaterials, a label-free identification tool for bacteria and yeasts has been created. The unique fingerprint obtained from the temperature-dependent resonance can provide information about the bacterial phases, such as growth and DNA denaturation. The method can also distinguish between gram-negative and gram-positive bacteria based on the temperature range of cell wall destruction.

Summary: Wild rice, with its unique ability to resist biotic and abiotic stress, has different microbial community structures compared to cultivated rice. Screening of bacteria from the rhizosphere and phyllosphere of different wild rice varieties revealed strains with inhibitory effects on rice blast and the ability to dissolve nutrients. Potted experiments showed that certain bacterial strains had positive effects on the growth of cultivated rice and improved its resistance to rice blast.

Summary: In recent years, there has been increasing interest in immobilizing plant growth-regulating microorganisms using various carriers. Among these carriers, polymeric materials, particularly those based on alginate, have been widely studied. This review provides an overview of research on matrix selection for effective encapsulation of microorganisms. The most favorable matrix formulation for high microbial survival and controlled release in the soil environment was identified, with the concentration of sodium alginate and the crosslinking agent CaCl2 being the most commonly used parameters. Additives such as starch, bentonite, and gelatin were found to have positive effects on structure changes, survival rate, biodegradation rate, and porosity. The encapsulation of microorganisms showed positive effects on plant growth parameters such as shoot and roots length and colonization rate. The review also discusses the state-of-the-art in immobilization parameters, alginate matrix components, encapsulation efficiency, physicochemical analysis of hydrogel capsules, and efficacy testing on plants.

Summary: Bacteria have been applied to crops to increase their productivity, with constantly changing formulations in liquid and solid-based products. Natural isolates are mainly selected as inoculants, as they exhibit various strategies in the rhizosphere to promote plant growth. Plants, on the other hand, have mechanisms to maintain beneficial microorganisms through the secretion of chemoattractants and signaling pathways. Transcriptomic approaches are useful in studying plant-microorganism interactions.

Summary: Microorganisms are crucial for the health and resilience of cnidarians. However, comparing cnidarian microbiomes across studies is challenging due to the variety of protocols used. In this study, researchers analyzed 12,010 cnidarian microbiome samples, along with samples from other organisms, to identify the factors influencing cnidarian microbiomes. They found a wide diversity of archaeal and bacterial phyla associated with cnidarians and identified key bacteria influenced by host characteristics, sampling depth, and ocean location. This systematic review provides a framework for understanding cnidarian microbiomes and their response to stress.

Summary: Trained immunity is a biological concept that has been demonstrated across different animal species, including humans, and has shown promise in providing protection against diseases in domestic animals. Recent breakthroughs in mice and humans have revealed that trained immunity can be induced through mucosal routes in addition to parenteral routes. However, there are differences between trained immunity in domestic animals compared to mice and humans, which pose new questions and challenges.

Summary: This study investigated the effect of Debaryomyces hansenii CBS 8339 on innate immune responses in mice. The results showed that oral delivery of D. hansenii for 7 days enhanced phagocytosis, respiratory burst activity, and nitric oxide production in mice before and after bacterial challenge. It also upregulated the expression of pro-inflammatory cytokines on day 7, but downregulated them on day 15. Furthermore, D. hansenii increased serum IgG and IgA titers in mice. Overall, short-term oral delivery of D. hansenii improved immune innate response in mice.

Summary: The development of alternative plant protein sources in aquaculture is a major challenge due to the high cost and continued shortage of animal protein sources. In this study, the effects of Tithonia diversifolia on the growth performance, feed efficiency, and metabolic biochemistry of Oreochromis mossambicus x Oreochromis niloticus juveniles were investigated. The results showed that T. diversifolia flour has an appropriate chemical composition and amino acid balance, without causing negative effects on the growth performance and metabolic biochemistry of the fish.
