Pulmonary infection by Lophomonas spp. and Aspergillus spp. in a B-cell acute lymphocytic leukemia patient from Chile.

The flagellated protozoan Lophomonas spp. is a commensal microorganism found in the intestinal tracts of cockroaches, termites, mites, and certain birds. It is the causative agent of a rare infection in humans called lophomoniasis, primarily affecting the lungs and mainly immunocompromised individuals.

Molecular Study of in Respiratory Samples of HIV Patients in Chile.

is an opportunistic fungus that causes potentially fatal pneumonia (PCP) in immunocompromised patients. The objective of this study was to determine the prevalence of in HIV patients through phenotypic and molecular study, to investigate the genetic polymorphisms of at the mitochondrial gene mtLSU and at the nuclear dihydropteroate synthase gene (), and by analysis of molecular docking to study the effect of mutations on the enzymatic affinity for sulfamethoxazole. A PCP prevalence of 28.

[Features of patients admitted for COVID-19 at a regional hospital in the Chilean Araucania Region].

Background: The Araucania region in Chile had the greatest COVID-19 incidence and lethality in Chile Aim: To describe the clinical characteristics and evolution of patients admitted for COVID-19 in a high complexity Hospital in the region of La Araucanía-Chile.

Material And Methods: Review of medical records of the first 169 patients aged 55 ± 17 years (50% women) admitted for COVID-19 between march and may, 2020 at a regional hospital in Temuco Chile.

Results: The most common comorbidities of these patients were hypertension, diabetes, and obesity.

High prevalence of CTX-M-1 group in ESBL-producing enterobacteriaceae infection in intensive care units in southern Chile.

Enterobacteria-producing extended-spectrum β-lactamases (ESBL) play an important role in healthcare infections, increasing hospitalization time, morbidity and mortality rates. Among several ESBLs that emerge from these pathogens, CTX-M-type enzymes had the most successful global spread in different epidemiological settings. Latin America presents high prevalence of CTX-M-2 in ESBL-producing enterobacterial infections with local emergence of the CTX-M-1 group.

[Cardiobacterium hominis pericarditis: an unusual case].

The case of a male patient under hemodialytic therapy, who developed right heart failure is presented. Echocardiography revealed pericardial effusion, constrictive pattem in the right cavities, septation, without valvular damage and preserved systolic and diastolic function. Pericardial drainage and extensive pericardiectomy was performed obtaining cultures of pericardial tissue positive for an HACEK group organism, Cardiobacterium hominis, with repeatedly negative blood cultures.
