Mitochondrial Genome Reduction and Accelerated Evolution in Planktonic Foraminiferans

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
The mitochondrial genomes of the eukaryotic lineage Retaria (Foraminifera and Radiolaria) show reductions in multiple gene categories, including complex I, transfer RNAs (tRNAs), ribosomal proteins, and ribosomal RNAs. In planktonic foraminifera, this reduction is even more pronounced, with the potential loss of atp and other genes.

Lower Respiratory Microbiome Dysbiosis Is Associated With Poor Prognosis in Acute Severe Lower Respiratory Tract Infection

MedComm, Volume 7, Issue 8, August 2026.
Acute severe lower respiratory tract infection (asLRTI) present lower alpha‐diversity in lower respiratory tract microbiome (LRTM). Five clusters (C1–C5) were grouped, and cluster C3 was strongly associated with poor prognosis and reduced survival.

Expression of EhRAD54, EhRAD51, and EhBLM proteins during DNA repair by homologous recombination in Entamoeba histolytica

Parasite, 2014
Entamoeba histolytica, the protozoan responsible for human amoebiasis, exhibits a great genome plasticity that is probably related to homologous recombination events.

Unusual MRI features in a case of presumed canine tick‐borne meningoencephalomyelitis

Veterinary Record Case Reports, Volume 14, Issue 3, August 2026.
Abstract A 7‐year‐old, standard, wire‐haired dachshund presented with quickly progressive multifocal central nervous system signs, which localised to the brainstem and cervical myelopathy, including reduced cervical and thoracic limb muscle tone and withdrawal reflexes. Magnetic resonance imaging revealed bilateral, approximately symmetric, T2‐weighted

Probable sepsis‐associated encephalopathy as a component of multiple organ dysfunction syndrome in a cat with pyothorax

Australian Veterinary Journal, Volume 104, Issue 8, Page 523-531, August 2026.
A 2‐year‐old male neutered domestic shorthair cat with bacterial pyothorax was referred to a tertiary hospital for treatment of sepsis. He met criteria for multiple organ dysfunction syndrome and developed new‐onset neurological dysfunction subsequent to the development of sepsis.

Chemokines in Alzheimer's Disease: Early Defence, Late Damage and the Impact of Sex and Infection

Basic &Clinical Pharmacology &Toxicology, Volume 139, Issue 2, August 2026.
ABSTRACT Chemokines constitute a versatile signalling network maintaining homeostasis and glia–neuron communication in the healthy brain but become progressively dysregulated during aging and Alzheimer's disease (AD). This review examines how chemokine systems transition from tightly regulated homeostatic signals to drivers of chronic neuroinflammation

Identification of a Benzenesulfonylpiperazine Derivative With In Vivo Efficacy Against Visceral Leishmaniasis

Chemical Biology &Drug Design, Volume 108, Issue 2, August 2026.
This work highlights the satisfactory pharmacokinetic profile of two benzenesulfonylpiperazine lead candidates, followed by in vivo assessment in a murine model of visceral leishmaniasis. This assessment identified compound 2 as moderately active at a lower dose, but its efficacy increased at higher doses, though with concerns regarding safety.

Tetraspanin-enriched microdomains play an important role in pathogenesis in the protozoan parasite Entamoeba histolytica.

PLoS Pathogens
Tetraspanins (TSPANs) are a family of highly conserved proteins present in a wide variety of eukaryotes. Although protein-protein interactions of TSPANs have been well established in eukaryotes including parasitic protists, the role they play in ...

Toxoplasma gondii‐Derived Soluble Factors Induce G2/M Phase Accumulation and p53‐Associated Mitochondrial Apoptosis in Human Umbilical Cord Mesenchymal Stem Cells

Journal of Cellular and Molecular Medicine, Volume 30, Issue 16, August 2026.
ABSTRACT Toxoplasma gondii infection poses potential risks to stem cell‐based therapeutic applications; however, the effects of parasite‐derived soluble factors on mesenchymal stem cells remain unclear. Here, we investigated the impact of T. gondii‐derived soluble factors (Tg‐SFs) on human umbilical cord‐derived mesenchymal stem cells (hUC‐MSCs).

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

Journal of Applied Entomology, Volume 150, Issue 7, Page 990-1015, August 2026.
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.
