Domination Versus Sisterhoods in the Blood Microbiota of Migrating Birds: Patterns of Within‐ and Between‐Individual Blood Parasite Diversity Revealed Through Metabarcoding

Integrative Zoology, EarlyView.
Avian haemosporidian blood parasites are typically identified through Sanger sequencing of a partial cytochrome b fragment, the MalAvi barcoding region. Next‐generation sequencing is seldom used for avian blood parasite identification; this study demonstrates a higher detection rate of co‐infections via metabarcoding and its possible implications ...

DNA Extraction from Protozoan Oocysts/Cysts in Feces for Diagnostic PCR

The Korean Journal of Parasitology, 2014
PCR detection of intestinal protozoa is often restrained by a poor DNA recovery or by inhibitors present in feces. The need for an extraction protocol that can overcome these obstacles is therefore clear. QIAamp® DNA Stool Mini Kit (Qiagen) was evaluated for its ability to recover DNA from oocysts/cysts directly from feces. Twenty-five Giardia-positive,

Diversity of the Microbiomes in the Larval and Adult Stages of the European Cherry Fruit Fly (Rhagoletis cerasi) and Identification of Potential Biocontrol Candidate Taxa

Entomologia Experimentalis et Applicata, EarlyView.
First comprehensive characterization of the R. cerasi microbiome is reported. Stage‐specific variations in microbial composition are documented. Multiple bacterial entomopathogen taxa are identified as potential biocontrol candidates for R. cerasi.

Two Theileria parva CD8 T cell antigen genes are more variable in buffalo than cattle parasites, but differ in pattern of sequence diversity [PDF]

, 2011
<p><b>Background:</b> Theileria parva causes an acute fatal disease in cattle, but infections are asymptomatic in the African buffalo (Syncerus caffer).

Transgenic selection and underlying mechanisms in apicomplexan parasites

The FEBS Journal, EarlyView.
Transgenic selection markers have driven genetic engineering in apicomplexans, enabling precise, iterative experiments. This review discusses mechanistic details of drug selection markers, strategies for marker recycling, and practical considerations for several clinically relevant parasites.

Cytosolic delivery of bacterial metabolites by riboflavin transporters promotes MR1 antigen presentation and MAIT cell recognition

Immunology &Cell Biology, EarlyView.
VitBAg antigen presentation is promoted through a cytosolic pathway that reaches ligand‐receptive MR1 to present to MAIT cells, like the riboflavin transport pathway. Riboflavin solute carrier transporters can promote this MR1 presentation, but they are not essential for this role, suggesting redundant pathways to uptake VitBAg.

Vectors and Vector‐Borne Diseases: Biology, Epidemiology and Integrated Control Strategies

Journal of Applied Entomology, EarlyView.
ABSTRACT Vector‐Borne Diseases (VBDs), transmitted by arthropods such as mosquitoes, ticks, fleas and sandflies, represent a significant threat to global health. These diseases can be caused by a variety of pathogens, including bacteria, viruses, protozoa, and helminths.

Effects of Sequence Alignment and Structural Domains of Ribosomal DNA on Phylogeny Reconstruction for the Protozoan Family Sarcocystidae [PDF]

Molecular Biology and Evolution, 2000
Finding correct species relationships using phylogeny reconstruction based on molecular data is dependent on several empirical and technical factors. These include the choice of DNA sequence from which phylogeny is to be inferred, the establishment of character homology within a sequence alignment, and the phylogeny algorithm used.
