Background: Herbicides are integral to agricultural weed management but can adversely affect non-target organisms, soil health, and microbiome. We investigated the effects of herbicides on the total soil bacterial community composition using 16S rRNA gene amplicon community profiling. Further, we aimed to identify herbicide-tolerant bacteria with plant growth-promoting (PGP) capabilities as a mitigative strategy for these negative effects, thereby promoting sustainable agricultural practices.

Article Synopsis
- Brucellosis, caused by B. abortus and B. melitensis, is a significant health threat, and standard treatments like rifampin and cotrimoxazole are facing rising antibiotic resistance.
- A systematic review analyzed 59 studies from 21 countries, revealing that cotrimoxazole resistance is at 3.4% and rifampin resistance at 4.6%, with trends showing increases over time, especially in B. melitensis.
- The study underscores the need for ongoing monitoring of antibiotic resistance, highlighting variations based on time, geography, and species, to inform treatment guidelines for pediatric brucellosis.
Immunogenic Consideration of a Designed Polypeptide Against Brucellosis Compared to RB51: An Study.

Department of Immunology, School of Medicine, Shahid Beheshti University of Medical Sciences, Tehran, Iran.
Background: Brucellosis in livestock and its transmission to humans through the consumption of contaminated dairy products is an important issue. The introduction of new approaches using immunogenic proteins against and diagnosing brucellosis is a serious issue in human health.
Methods: contains five proteins including: MOXR family ATPase-α2, T9SS C-terminal target domain-containing protein, Cobyric acid synthase, Hypothetical protein, and VirB11 type IV Secretion protein, which were considered and the designed recombinant polypeptide was produced and evaluated.

The deficiency of recombinant protein immune response could be compensated for by using nanoparticle platforms or adding immune enhancers, however existing vaccines or adjuvants struggle to elicit durable cellular immune responses. In this work, a protein nanoscaffold, lumazine synthase isolated from Brucella (BLS) was optimally designed that could facilitate cellular uptake of displayed antigens and the maturation of bone marrow-derived dendritic cells (BMDCs), and enhancing humoral immune responses. To enhance cellular immune response, chitosan hydrochloride-stabilized Pickering emulsion (CHSPE) was evaluated as an adjuvant for the BLS nanoscaffold-based vaccine.

Introduction: Soil bacteria offer a promising approach to bioremediate pesticide contamination in agricultural ecosystems. This study investigated the potential of bacteria isolated from rice paddy soil for bioremediating fipronil and thiobencarb, common agricultural pesticides.
Methods: Bacterial isolates capable of degrading fipronil and thiobencarb were enriched in a mineral salt medium.
