Neisseria weaveri is a commensal organism of the canine oral cavity and an occasional opportunistic human pathogen which is associated with dog bite wounds. Here we report the first complete genomic sequence of the N. weaveri NCTC13585 (CCUG30381) strain, which was originally isolated from a patient with a canine bite wound.

Under intensive aquaculture conditions, fish are exposed to many pathogens, due to that strengthening their immune system is an alternative significant way to reduce mortality rate and disease-related complications. Probiotics are valuable oral nutrition supplements for this purpose. In the present investigation, there were used Koi fish (n=120) with the characteristics of 10±3 Cm in length and...

A dietary deficiency in polyunsaturated fatty acids (PUFAs) and/or sterols can severely constrain growth and reproduction of invertebrate consumers. Single nutrients are potentially assigned to different physiological processes, for example to support defence mechanisms; therefore, lipid requirements of healthy and pathogen-challenged consumers might differ. In an oral exposure experiment, we e...

Abstract Background Enterocytozoon hepatopenaei (EHP) is an enteric pathogen that affects Penaeus vannamei and monodon shrimp in many SE Asian countries. In the western hemisphere, EHP was reported for first time 2016 farmed P. Venezuela. Anecdotal evidence suggests more prevalent grow-out ponds where salinity high (> 15 parts per thousand (ppt)) compared to with low salinities (< 5 ppt)....

the genus teucrium (germander) belongs to the family lamiaceae, within the subfamily ajugoideae .teucrium polium l. (labiatae) has long been recognized in folk medicine in the treatment of many pathophysiological implications, such as gastrointestinal disorders, inflammations, diabetes and rheumatism. in this study antimicrobial activity of two crude extracts obtained from teucrium polium l. wa...

colletotrichum species are associated with citrus plants as pathogens, saprobes and endophytes. according to the most recent multigene phylogenetic analysis, a lot of changes were happened in the taxonomy and species delimitation in the genus colletotrichum. in this investigation, 292 colletotrichum isolates were obtained from leaves, fruits and stems of citrus species at golestan, mazandaran, ...

The worldwide emergence of bacterial superbugs, and the limited number of effective antibiotic against them, has become an unresolved public catastrophe. According to a report from the World Health Organization in 2014, the resistance rate in a common bacterial pathogen such as Escherichia coli is high enough to limit the efficacy of currently available oral treatment options for patients with ...

Candida albicans and streptococci of the mitis group colonize the oral cavities of the majority of healthy humans. While C. albicans is considered an opportunistic pathogen, streptococci of this group are broadly considered avirulent or even beneficial organisms. However, recent evidence suggests that multi-species biofilms with these organisms may play detrimental roles in host homeostasis and...

Immune specificity is the degree to which a host's immune system discriminates among various pathogens or antigenic variants. Vertebrate immune memory is highly specific due to antibody responses. On the other hand, some invertebrates show immune priming, i.e. improved survival after secondary exposure to a previously encountered pathogen. Until now, specificity of priming has only been demonst...

Staphylococcus aureus is a major pathogen of varieties of oral mucous infection. Prostaglandin E2 (PGE2) is a pro-inflammatory factor and Cyclooxygenase 2 (COX-2) is a critical enzyme of PGE2 biosynthesis. The purpose of this study is to investigate whether Staphylococcus aureus can increase PGE2 production of oral epithelial cells and how PGE2 functions in the growth and adherence of Staphyloc...
