Of 106 African patients undergoing appendicectomy, 56 patients had stump invagination and 50 had simple ligation. The two groups were similar with respect to age, duration of symptoms, incision, degree of appendix inflammation and post-operative antibiosis. Patients whose wounds were drained were excluded. The frequency of wound infection was 8.9% in stump invagination and 6% in simple ligation...

The antagonistic activities of five biocontrol agents: Trichoderma harzianum, Gliocladium roseum, Bacillus subtilis, Streptomyces noursei and Streptomyces natalensis, were tested in vitro against Colletotrichum acutatum and Colletotrichum gloeosporioides, the causal agents of anthracnose disease in fruit crops. The microbial antagonists inhibited mycelial growth in the dual culture assay and co...

Curcuma Kwangsiensis S. G. Lee et C. F. Liang originates from the rhizome of the Curcuma Genus which is commonly used in traditional Chinese medicine. Pharmacological studies showed that curzerenone [1], curcumol, curdione, β-elemene, germacrone were the active ingredients of volatile oil from rhizoma curcuma. In addition, they had the effect of anti-inflammation, antibiosis [2], antivirus [3],...

Fungi that occur inside asymptomatic plant tissues are known as fungal endophytes. Different genera of fungal entomopathogens have been reported as naturally occurring fungal endophytes, and it has been shown that it is possible to inoculate plants with fungal entomopathogens, making them endophytic. Their mode of action against insects appears to be due to antibiosis or feeding deterrence. Res...

Numerous plants of medicinal value grow on Hainan Island (China). Given the lack knowledge phytochemical and pharmacological properties Michelia shiluensis Chun Y. F. Wu (M. shiluensis), application natural antioxidants antimicrobials in food industry has attracted increasing interest. This study aimed to compare chemical composition, free-radical-scavenging capacity, antibiosis aqueous extract...

Fermentation extracts from fungi isolated from vineyard ecosystems were tested for antimicrobial activities against a set of test microorganisms, including five food-borne pathogens (Staphylococcus aureus EP167, Acinetobacter baumannii (clinically isolated), Pseudomonas aeruginosa PAO1, Escherichia coli O157:H7 (CECT 5947) and Candida albicans MY1055) and two probiotic bacteria (Lactobacillus p...

A macromolecular polyanionic antibiotic produced by a marine bacterium belonging to the genus Alteromonas causes a large modification in bacterial respiration when added to the culture of several bacterial species in their early stage of growth. This antibiotic induces an increase of oxygen uptake and the production of hydrogen peroxide. The latter fact explains the high sensitivity of bacteria...

Microbial communities that are associated with plant roots are highly diverse and harbor tens of thousands of species. This so-called microbiome controls plant health through several mechanisms including the suppression of infectious diseases, which is especially prominent in disease suppressive soils. The mechanisms implicated in disease suppression include competition for nutrients, antibiosi...
