Antibacterial Effects of Black Cumin Seed Oil on Oral Microcosm Biofilms.
Microorganisms
October 2024
Interest in natural extracts for managing oral biofilms is increasing, with black cumin seed oil (BCSO) demonstrating efficacy against . The effectiveness of antibacterial agents should be evaluated using multi-species oral biofilm models that closely mimic actual conditions. This study aimed to compare the antibacterial effects of BCSO and chlorhexidine gluconate (CHX) on oral microcosm biofilms.

- Cadmium (Cd) is a harmful trace element that negatively impacts fish health, particularly through changes in their blood and plasma parameters.
- Key hematological parameters like red blood cell count and hemoglobin concentration are sensitive indicators of Cd toxicity, often leading to anemia and reduced oxygen delivery in fish.
- The review highlights various plasma biochemical markers that reflect organ health and metabolic function, while also exploring potential strategies, like dietary antioxidants, to alleviate the toxic effects of Cd exposure.
Article Synopsis
- This study investigated the effects of polyamide (PA) exposure on juvenile crucian carp, focusing on neurotoxicity, stress responses, and immune system effects.
- Crucian carp were exposed to various concentrations of PA for two weeks, showing significant inhibition of acetylcholinesterase (AChE) in key organs and increased levels of stress indicators like cortisol and HSP70.
- The findings highlight the toxic impact of microplastics, revealing adverse effects on the fish's neurochemical and immune functions.
Cadmium (Cd) in aquatic environments can cause environmental toxicity to fish and induce oxidative stress owing to an excessive production of reactive oxygen species in fish bodies. Fish have developed various antioxidant systems to protect themselves from reactive oxygen species; thus, a change in antioxidant responses in fish can be a criterion for evaluating oxidative stress resulting from Cd exposure. Because Cd exposure may be recognized as an exogenous substance by a fish body, it may lead to the stimulation or suppression of its immune system.

BFT is considered an innovative alternative for solving the problems of traditional aquaculture (for example, environmental pollution, high maintenance costs, and low productivity). Extensive research is being conducted to apply BFT to breed and raise many aquatic animal species.

There has been a recent increase in biofloc addition to fish culture, and this review examines changes this causes to the survival and growth rate of fish and its economic feasibility. Physiological activity and disease resistance of biofloc-fed fish is being extensively studied.

- Shrimp is a highly valuable aquaculture species and the most traded seafood worldwide, contributing significantly to economic growth in developing countries.
- Global shrimp production reached around 6.5 million tons in 2019, leading to a large-scale aquaculture industry.
- However, the industry faces challenges from viral diseases that cause significant production losses, prompting a review of shrimp viral diseases and recent trends by the World Organization for Animal Health.
