by Seiichiro Nakamura, Junya Yumioka, Seishu Kachi, Yasunori Baba, Shigeyuki Kawai Some macroalgae drift on the ocean and are stranded on coasts, and these stranded brown macroalgae are regarded to be degraded by organisms. Alginate is a major component of brown macroalgae. An uncovering of how carbon is cycled through brown macroalgae is needed to deeply understand coastal ecosystems.

by Eamon Gibbons, Mehbooba Tamanna, Bobby J. Cherayil Salmonella enterica serovars Typhimurium and Typhi are enteropathogens that differ in host range and the diseases that they cause. We found that exposure to a combination of hypotonicity and the detergent Triton X-100 significantly reduced the viability of the S. Typhi strain Ty2 but had no effect on the S. Typhimurium strain SL1344.

by Zheng Bian, Wenbo Liu, Junhua Jin, Yanling Hao, Linshu Jiang, Yuanhong Xie, Hongxing Zhang Shigella spp. and enteroinvasive Escherichia coli (EIEC) are widely distributed and can cause serious food-borne diseases for humans such as dysentery. Therefore, an efficient detection platform is needed to detect Shigella and EIEC quickly and sensitively.

Infantis) is a non-typhoid, zoonotic and foodborne serovar with worldwide distribution, and often associated with increasing antimicrobial resistance. Efflux pumps are antimicrobial resistance mechanisms able to promote and increase resistance levels to multiple distinct drug classes.

In the current investigation, rDNA-ITS (Internal transcribed spacer) and TEF (Transcriptional Elongation Factor) sequencing were used for molecular identification of six Beauveria bassiana strains.

by Anil K. Persad, Gireesh Rajashekara, Jeffrey T. LeJeune Shiga toxin-producing Escherichia coli (STEC) is estimated to cause over two million cases of human disease annually. Trinidad and Tobago is one of the largest livestock producer and consumer of sheep and goat meat in the Caribbean, however, the potential role of these animals in the epidemiology of STEC infections has not been previously described.

by Thankhoe A. Rants’o, Divan G. van Greunen, C. Johan van der Westhuizen, Darren L. Riley, Jenny-Lee Panayides, Lizette L. Koekemoer, Robyn L. van Zyl Current studies on Anopheles anticholinesterase insecticides are focusing on identifying agents with high selectivity towards Anopheles over mammalian targets. Acetylcholinesterase (AChE) from electric eel is often used as the bioequivalent enzyme to study ligands designed for activity and inhibition in human.

by Yan-Jun Li, Yun-Fan Yang, Yi-Jing Zhou, Rong-Hua Zhang, Cheng-Wei Liu, Hong Liu, Xiu-Gui Li, Wen Chen, Yan Chen, Yong-Ning Wu To estimate the incidence of foodborne gastroenteritis caused by nontyphoidal Salmonella enterica, Shigella, and Vibrio parahaemolyticus in China, population surveys and sentinel hospital surveillance were implemented in six provinces from July 2010 to July 2011, and a multiplier calculation model for the burden of disease was constru

by Durre Shahwar, Mohammad Yunus Khalil Ansari, Younghoon Park Lens culinaris is a proteinaceous food crop that is consumed worldwide for protein requirements. Mutation breeding has been used to improve protein content, yield, and related traits, as well as to select highly desirable mutants that are economically significant.

by Motuma Debelo, Nezif Mohammed, Abebaw Tiruneh, Tadele Tolosa Thermophilic Campylobacter species are common cause of animal and human bacterial diseases with growing resistance to antimicrobials. The aim of this study was to determine the prevalence and antimicrobial susceptibility pattern of Campylobacter species from bovine, knives and personnel in Jimma Town, Ethiopia.

by Marilou P. Sison-Mangus, Michael W. Kempnich, Monica Appiano, Sanjin Mehic, Terril Yazzie Auxospore production is a sexual reproductive strategy by diatoms to re-attain normal size after the size-reducing effect of clonal reproduction. Aside from the minimum size threshold used as a sex clock by diatoms, the environmental or chemical triggers that can induce sex in diatoms are still not well understood.

by Nehal A. Erfan, Mohamed S. Mahmoud, Hak Yong Kim, Nasser A. M. Barakat Nanofibrous morphology and the doping technique can overcome the problem of electron/hole fast recombination and improve the activity of titanium oxide-based photocatalysts. In this study, nanoparticulate and nanofibrous forms of CdTiO3-incorporated TiO2 were synthesized with different cadmium contents; the morphology and composition were determined by SEM, TEM, EDX, and XRD techniques.

by Anna-Delia Knipper, Narges Ghoreishi, Tasja Crease The consumption of raw milk from dairy cows has caused multiple food-borne outbreaks of campylobacteriosis in the European Union (EU) since 2011. Cross-contamination of raw milk through faeces is an important vehicle for transmission of Campylobacter to consumers. This systematic review and meta-analysis, aimed to summarize data on the prevalence and concentration of Campylobacter in faeces of dairy cows.

by Michael Anger, Christian Wendelborn, Eva C. Winkler, Christoph Schickhardt Background Data Sharing is widely recognised as crucial for accelerating scientific research and improving its quality. However, data sharing is still not a common practice. Funding agencies tend to facilitate the sharing of research data by both providing incentives and requiring data sharing as part of their policies and conditions for awarding grants.

by Tahmina Islam, M. K. Reddy Non-essential toxic heavy metal like cadmium (Cd2+) interferes with the plant growth and development in many ways. Cd2+ travels via plant transportation system, specifically through xylem and may integrate into the food chain causing unfavorable condition in human health. Therefore, strategies to develop Cd2+ tolerance and less accumulation in the plant system require urgent attention.
