Many environmental and phenological changes have recently modified their geographic patterns in many countries; thus, this study has updated the distribution of and in dog populations of selected regions of Central and Southern Italy. Also, collateral data on other endoparasites affecting the study population have been collected.

A 13-y-old, spayed female dog had regenerative anemia, lymphopenia, hypoalbuminemia, and elevated hepatic biochemical parameters. Liver biopsy revealed hepatic peliosis (hepatic sinusoidal angiectasis), frequently associated with perisinusoidal fibrosis. The dog was seroreactive to antigens by indirect fluorescent antibody assays, and quantitative PCR from blood identified subsp.

More than one-hundred species that affect animals and humans have been described, eight of which have been associated with emerging and underdiagnosed zoonoses. Most diagnostic studies in humans have used serology or molecular assays based on the 18S rRNA gene. Because the 18S rRNA gene is highly conserved, obtaining an accurate diagnosis at the species level is difficult, particularly when the amplified DNA fragment is small.

Aryl-chlorides and -fluorides are common building blocks, but their use in synthesis is limited by the high stability of their Ar-X bonds. The generation of aryl radicals via activation of strong Ar-X bonds is possible through the irradiation of tailor-made organic anions, which become reductants stronger than lithium metal. We report that the combination of visible light with the cheap diphenylacetic acid dianion is an even better tool, showing excellent activity across a variety of complex substrates and providing opportunities for late-stage drug modification.

Introduction/objectives: Risk factors for severe disease in boxer dogs with arrhythmogenic right ventricular cardiomyopathy (ARVC) are not well understood. This study's objective was to determine whether Striatin genotype or canine vector-borne pathogen (CVBP) exposure/infection in boxer dogs with ARVC was associated with disease severity or survival.

Animals: Sixty-four client-owned, adult boxer dogs with ARVC were included in the study.

Article Synopsis
  • Bartonella species are intracellular bacteria linked to various human diseases, often transmitted through infected bodily fluids or vectors, but infections have been reported without clear contact to animals or insects.
  • These bacteria are associated with neurological conditions, including neuroretinitis and encephalitis, primarily linked to species like Bartonella henselae and B. quintana, and can also cause peripheral neuropathies.
  • Recent studies have detected Bartonella DNA more frequently in patients with neuropsychiatric disorders, suggesting a potential connection between these infections and conditions such as schizophrenia and psychoses.

Article Synopsis
  • Bartonella spp. are bacteria that can cause infections in animals and humans, and they are spread by vectors like sand flies.
  • A study analyzed 634 sand fly specimens in Brazil from 2017-2021 and found that 8.7% contained Bartonella DNA using specific PCR techniques.
  • Phylogenetic analysis indicated some sequences of Bartonella were related to known species, suggesting that sand flies might play a role in the transmission of these bacteria.

Article Synopsis
  • Vitamin B12 deficiency can lead to serious health issues like megaloblastic anemia and neurological damage, often caused by malabsorption or dietary restrictions.
  • The study investigates the impact of specific MTHFR gene polymorphisms (C677T and A1298C) on anemia and gastritis in Italian patients with B12 deficiency, revealing significant correlations between these genetic variants and hematological issues.
  • The findings indicate that reduced MTHFR enzyme activity may worsen the symptoms of vitamin B12 deficiency and increase the risk of developing atrophic gastritis.

  • Mild Cognitive Impairment (MCI) is a condition that falls between normal cognitive decline and dementia, with unclear roles of infections in its development.
  • A study examined the link between Bartonella spp. infection and cognitive decline in older adults, finding no significant difference in infection rates between those with and without MCI.
  • Though a high prevalence of Bartonella spp. infection was noted in participants without MCI, the small sample size limits the conclusions about its influence on MCI.

This study aimed to determine the sequence type (ST) of Bartonella henselae infecting small Indian mongooses from Saint Kitts via multi-locus sequence typing (MLST). This investigation used stored EDTA blood (n = 22) samples from mongooses previously identified as positive for B. henselae.

Dispersion interactions are ubiquitous weak interactions that can play a role in many chemical events. Tailor-made catalysts and additives can lead to more selective reactions by properly exploiting dispersion interactions. Although radical-π dispersion interactions are known to have an important stabilizing role, this concept has been so far overlooked in synthetic photochemistry.

  • Babesia and Bartonella co-infections are increasingly recognized in patients with chronic illnesses, challenging traditional views on infectious diseases.
  • This study uses advanced molecular diagnostics to confirm Babesia odocoilei infections in humans, revealing a higher occurrence than previously thought.
  • Six out of seven infected individuals also had co-infections with different Bartonella species, highlighting the need for more awareness and understanding of these pathogen dynamics.

Introduction: The potential role of pathogens, particularly vector-transmitted infectious agents, as a cause of psychosis has not been intensively investigated. We have reported a potential link between spp. bacteremia and neuropsychiatric symptoms, including pediatric acute onset neuropsychiatric syndrome and schizophrenia.

Bartonellosis refers to disease caused by the Bartonella genus of bacteria. The breadth of disease manifestations associated with Bartonella is currently expanding and includes regional lymphadenopathy, rheumatic, ocular, and neurological disorders. The dearth of knowledge regarding diagnosis, treatment and pathogenesis of this disease can be partially attributed to the lack of a reliable small animal model for the disease.

Aims: Systolic blood pressure (SBP) drops recorded by 24-h ambulatory blood pressure (BP) monitoring (ABPM) identify patients with susceptibility to reflex syncope and orthostatic intolerance. We tested the hypothesis that treatments aimed to increase BP (reassurance, education, and lifestyle measures plus pharmacological strategies) can reduce SBP drops.

Methods And Results: This was a multicentre, observational proof-of-concept study performed in patients with reflex syncope and/or orthostatic intolerance and with SBP drops on a screening ABPM.

Case Summary: A 10-year-old domestic shorthair cat presented for lethargy, anorexia and labored breathing. Significant pleural and pericardial effusions prompted thoracocentesis and pericardiocentesis. Cytologic evaluation of the pericardial effusion revealed a highly cellular hemorrhagic, eosinophilic (12%) effusion, with many markedly atypical suspected mesothelial cells, interpreted as concerning for neoplasia.

Background: The worldwide increase in Crohn's disease (CD) has accelerated alongside rising urbanization and accompanying decline in air quality. Air pollution affects epithelial cell function, modulates immune responses, and changes the gut microbiome composition. In epidemiologic studies, ambient air pollution has a demonstrated relationship with incident CD and hospitalizations.

Pathogen environmental stability is an often-neglected research priority for pathogens that are known to be vector-transmitted. , the etiologic agent of Cat Scratch Disease, has become a "pathogen of interest" in several serious human illnesses, which include neoplastic, cardiovascular, neurocognitive, and rheumatologic conditions. Survival in the flea gut and feces as well as the association with a biofilm in culture-negative endocarditis provides insight into this organism's ability to adjust to environmental extremes.

Bacteria of the genus , a member of the , are fastidious, Gram-negative, aerobic bacilli that comprise numerous species, subspecies, and genotypes. Bartonella henselae, with a worldwide distribution, infects cats, dogs, horses, humans, and other mammals. Diagnostically, direct detection of Bartonella henselae in patient blood specimens by culture or molecular methods is required to confirm infection with this bacterium.
