Maize lethal necrosis (MLN), caused by co-infection of maize chlorotic mottle virus and sugarcane mosaic virus, can lead up to 100% yield loss. Identification and validation of genomic regions can facilitate marker assisted breeding for resistance to MLN. Our objectives were to identify marker-trait associations using genome wide association study and assess the potential of genomic prediction for MLN resistance in a large panel of diverse maize lines.

We evaluated the performance of a fourth-generation antigen/antibody (Ag/Ab) assay for detecting HIV-1 infection on dried blood spots (DBS) both in a conventional laboratory environment and in an epidemiological survey corresponding to a real-life situation. Although a 2-log loss of sensitivity compared to that with plasma was observed when using DBS in an analytical analysis, the median delay of positivity between DBS and crude serum during the early phase postacute infection was 7 days.

Influenza is a major global public health threat as a result of its highly pathogenic variants, large zoonotic reservoir, and pandemic potential. Metagenomic viral sequencing offers the potential for a diagnostic test for influenza virus which also provides insights on transmission, evolution, and drug resistance and simultaneously detects other viruses. We therefore set out to apply the Oxford Nanopore Technologies sequencing method to metagenomic sequencing of respiratory samples.

Background In animal agriculture, antimicrobials (AM) are used to control infectious diseases whose incidence and severity vary across production systems, but may contribute to select AM resistant bacteria, potentially disseminating in humans. Antimicrobial resistance (AMR) represents a public threat, leading policymakers to implement measures to reduce antimicrobial use (AMU).

A detailed study on two Nepeta species. The essential oils of two Nepeta species might be used as Germacrene D source. The Nepeta heliotropifolia and N. congesta subsp. cryptantha flowers being rich in rosmarinic acid and having antioxidant potential, and their essential oils could be source for nutraceutical, food and drug industries. Abstract In the present study, the essential oil and aroma compositions of Nepeta heliotropifolia (NH) and N. congesta subsp.

In this study, the ability of H. illucens larvae (black soldier fly (BSF)) to metabolise different semisolid biowastes (e.g. kitchen waste, animal manure) has been applied to the treatment of landfill leachate.

Nowadays, fertilization and pest control are carried out using chemical compounds that contaminate soil and deteriorate human health. Plant growth promoting bacteria endophytes (PGPBEs), are a well-studied group of bacteria that offers benefits to the host plant, such as phytostimulation, biofertilization, and protection against other microorganisms.

Environmental exposure to arsenic (As) and fluoride (F) in the recent year has been increased because of excessive use of naturally contaminated ground water. Surface water is also regularly contaminated with these elements in various industrial areas. Arsenicosis and fluorosis upon individual exposure of As and F are reported in many studies. A syndrome of endemic As poisoning and fluorosis occurs during concurrent exposure of As and F.

An enzyme immunoassay (EIA) was developed based on a generic and highly sensitive monoclonal antibody (mAb) enabling simultaneous detection of all fluoroquinolone/quinolone antibiotics (FQs) approved for the treatment of food-producing animals. To generate the group-specific antibody, norfloxacin was conjugated to glucose oxidase (GlcOX) by one-step carbodiimide method and used as immunogen.

Vibrioparahaemolyticus is a leading seafood-borne pathogen that causes gastroenteritis, septicemia, and serious wound infections due to the actions of virulence-associated proteins. We compared the extracellular proteins of nonvirulent JHY20 and virulent ATCC 33847 V. parahaemolyticus reference strains.

Community-onset bloodstream infections (CO-BSI) are major causes of severe febrile illness and death worldwide. In light of new data and the growing problem of antimicrobial resistance (AMR) among pathogens causing BSI, we undertook a systematic review of hospital-based studies of CO-BSI among patients hospitalized with fever.
