A Low Number of Baselines γδ T Cells Increases the Risk of SARS-CoV-2 Post-Vaccination Infection.

The COVID-19 pandemic is the biggest global health problem in the last hundred years. The efficacy of the vaccine to protect against severe disease is estimated to be 70-95% according to the studies carried out, although there are aspects of the immune response to the vaccine that remain unclear. Humoral and cellular immunity after the administration of three doses of the Pfizer-BioNTech and Oxford AstraZeneca vaccines against SARS-CoV-2 over one year and the appearance of post-vaccination COVID-19 were studied.

Missing Cases of Herpes Simplex Virus (HSV) Infection of the Central Nervous System When the Reller Criteria Are Applied for HSV PCR Testing: a Multicenter Study.

Previous studies suggested that herpes simplex virus (HSV) PCR testing can be safely deferred in patients with normal cerebrospinal fluid (CSF) white blood cell (WBC) counts and protein levels as long as they are older than 2 years of age and are not immunocompromised, the so-called Reller criteria. In this multicenter study, we retrospectively assessed the validity of these screening criteria in our setting. A total of 4,404 CSF specimens submitted for HSV PCR testing to the respective microbiology laboratories at the participating hospitals between 2012 and 2018 were included.

[Invasive listeriosis in Valencian community, Spain, during the period 2008-2010].

Background: Listeria monocytogenes is an uncommon cause of disease, although in certain age groups (infants, elderly, pregnant women and immunocompromised) may be an important cause of meningoencephalitis, and bacteremia. The aim of this study was to detect the incidence of invasive listeriosis cases found in Valencia during a period of 3 years.

Methods: A retrospective study of invasive listeriosis detected in the period 2008-2010 was carried out.

Occurrence and genotypes of Giardia isolated from lambs in Spain.

Three hundred and eighty six faecal specimens were randomly collected from 1- to 3-month-old lambs from 16 farms in Spain to investigate the presence of different genotypes of Giardia duodenalis. Individual specimens were examined by IFA (Immunofluorescence assay) and beta-giardin PCR polymerase chain reaction. Cysts of G.
