Article Synopsis
- The study aimed to identify the presence of Lactococcus petauri, L. garvieae, and L. formosensis in fish and environmental samples near a fish farm outbreak in California during 2020, and compare their virulence in different fish species.
- Researchers isolated Lactococcus spp. using bacterial culture methods and detected their DNA through quantitative PCR in various fish tissues and environmental samples from four lakes.
- Results showed Lactococcus garvieae in Largemouth Bass and indicated that Rainbow Trout infected with L. petauri had high mortality rates, while Largemouth Bass did not show infection symptoms, highlighting the use of qPCR for monitoring and variances in bacterial virulence.
Piscine lactococcosis is an emergent bacterial disease that is associated with high economic losses in many farmed and wild aquatic species worldwide. Early and accurate detection of the causative agent of piscine lactococcosis is essential for management of the disease in fish farms. In this study, a TaqMan quantitative polymerase chain reaction (qPCR) targeting the 16S-23S rRNA internal transcribed spacer region was developed and validated.

Case Presentation: We report a case of a 51-year-old Chinese woman who was evacuated from Wuhan, China and diagnosed with coronavirus disease 2019 infection at a Southern California quarantine facility. Her clinical course was notable for high fevers, night sweats, productive cough, transient leukopenia, lymphopenia, thrombocytopenia, and transaminitis.
