Population and herbarium genomics provide a comprehensive framework for a revision of Microcoleus (Cyanobacteria)

Journal of Phycology, EarlyView.
Abstract Microcoleus is a cosmopolitan, filamentous cyanobacterium and a key component of biological soil crusts—complex microbial communities essential for primary production in diverse terrestrial environments. Here, we performed a taxonomic revision of several species of Microcoleus based on a large population genomic dataset.

Health-Based Cyanotoxin Guideline Values Allow for Cyanotoxin-Based Monitoring and Efficient Public Health Response to Cyanobacterial Blooms

Toxins, 2015
Human health risks from cyanobacterial blooms are primarily related to cyanotoxins that some cyanobacteria produce. Not all species of cyanobacteria can produce toxins.

Cyanotoxins Occurrence in Portugal: A New Report on Their Recent Multiplication

Toxins, 2020
Historical reports show that in Portugal, cyanotoxins reports were mainly in the Center (cylindrospermopsins) and South (cylindrospermopsins, saxitoxins) regions of the country apart from the well distributed microcystins.

Effects of cyanobacterial extracts containing anatoxin-a and of pure anatoxin-a on early developmental stages of carp

Ecotoxicology and Environmental Safety, 2009
This study compares the effects of pure anatoxin-a and cyanobacterial extracts of an anatoxin-a producing strain on early stages of development of carp. Carp eggs were exposed from 2:30 h to 4 days post-fertilization to different ecologically relevant concentrations of anatoxin-a, provided as pure toxin or contained in the cyanobacterial extracts.

Determination of microcystins, nodularin, anatoxin-a, cylindrospermopsin, and saxitoxin in water and fish tissue using isotope dilution liquid chromatography tandem mass spectrometry.

Journal of Chromatography A, 2019
Cyanobacteria can form dense blooms under specific environmental conditions, and some species produce secondary metabolites known as cyanotoxins, which present significant risks to public health and the environment.

Co‐Coverage of Essential Interventions Across the Health System Continuum of Care for Improving Child Nutrition in Ethiopia

Maternal &Child Nutrition, EarlyView.
ABSTRACT This study aimed to assess the coverage of essential nutrition interventions delivered through the health system and explored the relationship between co‐coverage and child‐ and maternal‐level factors, household‐level factors, and access to healthcare facilities.

Identification of harmful cyanobacteria in the Sacramento-San Joaquin Delta and Clear Lake, California by DNA barcoding. [PDF]

, 2013
Accurate identification of cyanobacteria using traditional morphological taxonomy is challenging due to the magnitude of phenotypic plasticity among natural algal assemblages.

Impact of CD19 CAR T‐Cell Therapy on Pathogen‐Specific Antibody Titers in Lymphoma Patients

Transplant Infectious Disease, EarlyView.
Patients with lymphoma undergoing CD19 CAR T‐cell therapy experience prolonged hypogammaglobulinemia and B‐cell aplasia. We investigate its impact on immunity against measles virus (MeV), mumps virus (MuV), rubella virus (RuV), varicella‐zoster virus (VZV), pneumococcal capsular polysaccharide, Haemophilus influenzae type B (Hib), and tetanus toxoid ...
