[Rectal lesions and liver lesions caused by syphilis].

Background: Syphilis is a sexually transmitted disease, caused by the spirochete Treponema Pallidum. Many different manifestations exist, which can complicate diagnosis.

Case: A 36-year-old man with a known HIV infection, presented himself with rectal blood loss and abdominal pain.

Comparison of the Performance of the PanBio COVID-19 Antigen Test in SARS-CoV-2 B.1.1.7 (Alpha) Variants versus non-B.1.1.7 Variants.

This study evaluates the performance of the PanBio COVID-19 antigen (Ag) test as part of a hospital infection control policy. Hospital staff was encouraged to get tested for COVID-19 when presenting with SARS-CoV-2-related symptoms. In a period of approximately 5 months, a steady decline in the performance of the Ag test was noted, epidemiologically coinciding with the rise of the SARS-CoV-2 B.

From a case-control survey to a diagnostic viral gastroenteritis panel for testing of general practitioners' patients.

Objective: To evaluate the pathogenicity of a broad range of 11 possible gastroenteritis viruses, by means of statistical relationships with cases vs. controls, or Ct-values, in order to establish the most appropriate diagnostic panel for our general practitioner (GP) patients in the Netherlands (2010-2012).

Methods: Archived stool samples from 1340 cases and 1100 controls were retested using internally controlled multiplex real-time PCRs for putative pathogenic gastroenteritis viruses: adenovirus, astrovirus, bocavirus, enterovirus, norovirus GI and GII, human parechovirus, rotavirus, salivirus, sapovirus, and torovirus.

Feasibility of a quantitative polymerase chain reaction assay for diagnosing pneumococcal pneumonia using oropharyngeal swabs.

Streptococcus pneumoniae is the most important pathogen causing community-acquired pneumonia (CAP). The current diagnostic microbial standard detects S. pneumoniae in less than 30% of CAP cases.

Infection of lung cavitations in a young dog owner with Hodgkin's lymphoma caused by , without a dog bite: confirmed zoonotic transmission by tagmentation microbiome analysis.

is a known pathogen in humans, mostly reported after animal bite incidents. Atraumatic infections have been described, especially in immunocompromised patients. A 20-year-old patient with a history of stage IV Hodgkin's lymphoma with cavitating pulmonary lesions presented with a bilateral pneumonia.
