Article Synopsis
- The Lymphogranuloma venereum (LGV) outbreak in Buenos Aires, first identified in 2017, revealed unique strain characteristics that prompted further study.
- Researchers analyzed 88 LGV strains from symptomatic patients between 2017 and 2019, identifying various types including L2b, L1-like, and L2, with notable genetic diversity.
- By employing Multilocus Sequence Typing (MLST), they discovered new strain mutations and sequence types, highlighting the evolving nature of LGV infections in a relatively small geographical area.
Background: (CT) can infect the anorectum producing various signs and symptoms. There is scarce literature regarding the differences between LGV and non-LGV CT anorectal manifestations. We compare the clinical spectrum of LGV and non-LGV infections.

It is unclear whether development and integration of those new neurons are also affected by age. Here, we show that adult-born granule cells (GCs) in aging mice are scarce and exhibit slow development, but they display a remarkable potential for structural plasticity.

We examined the remodeling of dentate gyrus microcircuits in mice in an enriched environment (EE). Short exposure to EE during early development of new GCs accelerated their functional integration.
