Microbial biofilms have raised significant concerns within the healthcare, medical, and food industries due to their inherent resistance to conventional antibiotics and cleaning methods, as well as their ability to firmly attach to surfaces, leading to enduring contamination concerns. A biofilm constitute a structural community of microorganisms, encased in a framework of extracellular polymeric substances. Biofilms pose a substantial challenge in the management of bacterial infections and stand as primary factors contribute to the enduring nature of these infections. Depending on their community microbiological makeup and the surrounding conditions, bacteria can create different types of single and multispecies biofilms. Over the past 20 years, interest in the study of bacterial biofilm formation has increased due to the exquisite intricacy of these multicellular communities and their role in infectious illnesses. Biofilms can form on almost any surface and can be advantageous or harmful, depending on the surface and how the community uses it. Extensive researchers have tackled the progressions in comprehending structural and functional variations, along with the roles that biofilms perform in illness and host–pathogen relationships.","PeriodicalId":8978,"journal":{"name":"Biologia","volume":"56 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142196928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 22 mangrove species, belonging to 12 families were documented wherein the most abundant was Sonneratia alba, followed by Nypa fruticans, then by Avicennia rumphiana. It was found that the diversity (Shannon-Wiener) of riverine mangroves (0.94 ± 0.07; 1.20 ± 0.04) was significantly higher than the fringe at the middleward and seaward/along the water (p < 0.001). In the fringe mangrove forests, the mangrove species Aegiceras corniculatum was associated with the middleward zone, and Camptostemon philippinensis, Aegiceras floridum, Rhizophora mucronata, Sonneratia alba, and Lumnitzera littorea were associated with the seaward zone, whereas landward zone of fringe and all the zones in riverine were generally associated by species with low to optimum salt tolerances such as Nypa fruticans, and Avicennia rumphiana as the most abundant. As well, a total of 14 mangroves have been identified as indicator species. Lastly, mangrove species can be generally classified as riverine and fringing based on the environmental factors explaining their distributions, and it has been found that soil porosity, water content, soil salinity, and distance from the sea or river’s edge were the most significant environmental factors that determine diversity patterns.","PeriodicalId":8978,"journal":{"name":"Biologia","volume":"79 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142196930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cellular defense mechanisms such as morphological changes (size or appearance), production of photo-protectant compounds, and enhancement of antioxidant activities, all of which may contribute to the suppression of ROS and significantly increase survival rates under UV radiation. In this study, five UVB-resistant plant growth-promoting methylotrophs (Methylorubrum thiocyanatum (SD2), Rhodococcus kroppenstedtii (UK3), Methylorubrum populi (KD5), and Methylobacterium brachiatum (KD1 and SD3)) were investigated as adaptive strategies against UVB radiation. Exposure to UVB radiation revealed that methylotrophs changed their morphology to club or dumbbell shapes, and formed biofilm-like structures. Furthermore, Fourier transform-infrared spectroscopy (FTIR) and Gas chromatography-mass spectroscopy (GC–MS) analyses of the methanol-based intracellular extracts of methylotrophs revealed the presence of carotenoids, flavonoids, fatty acids, and antioxidants. Additionally, methylotrophs showed enhanced antioxidant activities such as superoxide dismutase, peroxidase, phenylalanine ammonia-lyase, and proline content with increased UVB exposure (1 -4 h). These findings demonstrate the ability and various adaptation strategies of methylotrophs to survive UVB exposure. These adaptive strategies may be one reason for the promotion of plant growth by methylotrophs under UVB radiation.\u0000","PeriodicalId":8978,"journal":{"name":"Biologia","volume":"54 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142196929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the aim of the current study is to identify and isolate a new antimicrobial agent from Streptomyces sp. effective against several pathogenic microbes, including multidrug resistant (MDR) pathogens, using agriculture waste. Streptomyces isolate strain from the Egyptian soil was isolated, identified and grown on a local agricultural waste. The antimicrobial activity of the fermentation medium was tested against several pathogens using the well diffusion method. The most suitable fermentation and environmental factors for the maximum production of the antimicrobial bioactive compound was determined. Finally, the bioactive compound was purified, and characterized using several chromatographic and instrumental analyses. We identified Streptomyces bingchenggensis FHM200 isolate strain grown on peanut shells wastes. The maximum antimicrobial activity was attained by incubation with 2% (v/v) of the isolated strain (105 spores / mL) at temperature range of 28–30℃ and pH range of 7.5 to 8 for 5 days, supplemented with potassium nitrate 0.2% (w/v) and dipotassium hydrogen phosphate (1 g/L). Finally, we managed to isolate and purify a novel bioactive compound; hexyl (2-hydroxyhexyl) phthalate, that possessed a promising antimicrobial activity against all tested pathogens with MIC of 70 µg/mL for Bacillus cereus ATCC 33018, 150 µg/mL for Aspergillus niger NRRL 326, and for MDR pathogens; 2500 µg/mL for methicillin resistance Staphylococcus aureus (MRSA) ATCC 43300, and 3000 µg/mL for both Escherichia coli 797, and Candida albicans 210.

Cytotoxic effects of plant extract were determined. The protective action of plant extract against DNA damage was shown in the study, as well. The amoebicidial activity of H. perforatum ethanolic extracts was set on using in vitro ethanolic extraction (in quantities from 5, 10, 15, 20, 25, and 30 mg/ml). Different concentrations of H. perforatum ethanolic extracts and trophozoites were merged to determine the amoebicidial activity of the plant extract. Cytotoxicity was evaluated using a modified 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2 H-tetrazolium bromide (MTT) assay. The effect of plant extract on hydroxyl radical-induced DNA damage was determined by electrophoresis on agarose gel. The growth of trophozoites terminated in H. perforatum ethanolic extracts with 50% inhibitory concentrations (IC50)/24 h for 30 mg/ml. The same extract solution had more vigorous amoebicidial activity on the trophozoites with IC50/72 h. Hypericum perforatum showed more substantial inhibitory effects on human cervical carcinoma cell lines (HELA) at concentrations of 5, 2.5, and 1.25 mg/mL at 72 h. The ethanolic extract of H. perforatum was more effective against Acanthamoeba and showed DNA protective activity. Hypericum perforatum extract has amoebicidial potential against A. castellani trophozoites, the causative agent of acanthamoebiasis.

The most common parasites were Myxobolus spp. and Henneguya spp., and freshwater fish were about four times more parasitized than saltwater ones. Thus, the knowledge of myxosporean diversity in South America seems to be shaped more by the presence of research groups in each country than by the continent’s biogeographical conditions.

Unfortunately, very little is known about the extent, causes, and frequency of this phenomenon. Therefore, in this paper, we investigate a scale of vandalism in studies using nest-boxes in Poland. Data from published papers (n = 256) indicated that researchers are aware of the devastation and destruction of nest-boxes, but often lacking detailed reports. We further validated this data through emails or phone calls to the authors. Surprisingly, only 14 (5.5%) papers mentioned vandalism, and during interviews, we found that vandalism occurred in 51.7% of studies. In response to vandalism, researchers have taken measures to reduce the scale of damages, such as hanging boxes far from paths and roads, placing them above 3 m from the ground, or, more recently, using security cameras. Although vandalism was quite common, its scale was rather marginal, with some local exceptions. For a better understanding of this phenomenon, we suggest including more detailed information on vandalism in future papers, which could aid in the interpretation of scientific data, as well as in nature conservation.","PeriodicalId":8978,"journal":{"name":"Biologia","volume":"4 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142196932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is important to understand how their evolution and demographic parameters have changed throughout time. Since salinity is a relevant condition in the soils around the World and particularly in Mexico, the major goal of the current research is to understand the life cycle strategies of two springtail species from saline soils in Mexico. The studied species are Clavisotoma filifera and Brachystomella gabrielae, both widely distributed in Mexico, but their development or life history strategies are unknown. We found from laboratory cultures that C. filifera had a shorter life cycle and a faster reproduction rate than B. gabrielae. Nevertheless, both species show the same number of developmental stages, but there are interspecific differences in their duration. Although both species continuously reproduce throughout the year, the reproductive rate is lower in the months that are associated with the dry season at the source site. Additionally, we discovered variations in both the size and number of eggs in each species. It was found that the species under study had various life strategies for growth in the same environment. Clavisotoma filifera shows a more r-focused strategy (high fecundity, numerous offspring, shorter gestation and faster maturity), B. gabrielae shows an opposite strategy, closer to q strategy, with a lower fecundity, larger eggs, fewer reproductive events and slower maturity.","PeriodicalId":8978,"journal":{"name":"Biologia","volume":"204 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142196964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
