Bartonellae are emerging vector-borne pathogens infecting erythrocytes and endothelial cells of various domestic wild mammals. Blood samples were collected from canids in Iraq under the United States Army zoonotic disease surveillance program. Serology was performed using an indirect immunofluorescent antibody test for B. henselae, clarridgeiae, vinsonii subsp. berkhoffii bovis. Overall seroprevalence 47.4% dogs (n = 97), 40.4% jackals 57) 12.8% red foxes 39). Bartonella species DNA...
We detected Bartonella in 11 of 109 insectivorous bats from France and 1 26 Spain. These genetic variants are closely related to bat-associated described Finland the United Kingdom B. mayotimonensis, agent a human endocarditis case States.
The coronavirus disease 2019 (COVID-19) pandemic has highlighted the vulnerability of residents and staff members in long-term care facilities (LTCFs) (1).Although skilled nursing (SNFs) certified by Centers for Medicare & Medicaid Services (CMS) have federal COVID-19 reporting requirements, national surveillance data are less readily available other types LTCFs, such as assisted living (ALFs) those providing similar residential care.However, many state territorial health departments...
Abstract Objective: Resilience of the healthcare system has been described as ability to absorb, adapt, and respond stress while maintaining provision safe patient care. We quantified impact that stressors associated with COVID-19 pandemic had on safety, measured by central line-associated bloodstream infections (CLABSIs) reported Centers for Disease Control Prevention’s National Healthcare Safety Network. Design: Acute care hospitals were mandated report markers resource availability...
We examined the association between influenza vaccination policies at acute care hospitals and coverage among healthcare personnel for 2021-22 season. Mandatory masking unvaccinated were associated with increased odds of vaccination. Hospital employees had higher than licensed independent practitioners.
Blood-feeding arthropods play a major role in the transmission of several flaviviruses, which represent an important problem for human health. Currently, dengue is one most arboviral emerging diseases worldwide. Furthermore, some previous studies have reported presence viral nucleic acids and antibodies against virus (DENV) wild animals. Our knowledge played by wildlife reservoirs sylvatic maintenance DENV remains limited. objective was to screen blood-feeding ectoparasites (bat flies) their...
Although emerging nonviral pathogens remain relatively understudied in bat populations, there is an increasing focus on identifying bat-associated bartonellae around the world. Many novel Bartonella strains have been described from both bats and their arthropod ectoparasites, including mayotimonensis, a zoonotic agent of human endocarditis. This cross-sectional study was designed to describe isolated sampled Mexico evaluate factors potentially associated with infection. A total 238 belonging...
The Advisory Committee on Immunization Practices recommends that health care personnel (HCP) receive an annual influenza vaccine and everyone aged ≥6 months stay up to date with recommended COVID-19 vaccination.

Abstract Alpine environments underwent dramatic transformation during glacial–interglacial cycles, with the consequence that geographical, ecological and demographic changes of alpine populations provided opportunity for formation neoendemic species. Several biogeographical models have been proposed to account unique history populations, different expectations genetic divergence speciation. The expanding archipelago model proposes expand spatially demographically glacial events, dispersing...
Bartonella infection among cats from shelters can pose a health risk to adopters. henselae is the most common species, with B. clarridgeiae and koehlerae being less common. The lower rates of by latter species may reflect their rarity or an inefficiency culture techniques.

Because COVID-19 case data do not capture most SARS-CoV-2 infections, the actual risk of severe disease and death per infection is unknown. Integrating sociodemographic into analysis can show consequential health disparities.
Because of overpopulation, stray/feral cats were captured on military bases in Iraq as part the US Army Zoonotic Disease Surveillance Program. Blood samples collected from 207 cats, mainly Baghdad but also North and West Iraq, to determine prevalence Bartonella Toxoplasma infections. Nine (4.3%) all Baghdad, bacteremic with B. henselae type I. Seroprevalence was 30.4% for T. gondii, 15% henselae, 12.6% clarridgeiae. Differences by location statistically significant, because most seropositive...
Infection prevention and control (IPC) in health care facilities is essential to protecting patients, visitors, personnel from the spread of infectious diseases, including Ebola virus disease (Ebola). Patients with suspected are typically referred specialized treatment units (ETUs), which have strict isolation IPC protocols, for testing (1,2). However, settings where contact tracing inadequate, patients might first seek at general facilities, often insufficient capacity (3-6). Before...
