Aspergillosis is a major cause of morbidity and mortality in penguins, with triazole antifungal drugs being commonly used for prophylaxis and treatment. This report describes 15 cases of fatal hemolysis associated with liquid itraconazole and voriconazole formulations administered to African penguins () from four institutions. All penguins underwent stressful events (e.

- 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.
Lactococcus petauri is an important emergent aquaculture pathogen in the USA. To better understand environmental conditions conducive to piscine lactococcosis and the susceptibility of fish species, laboratory-controlled challenges were used as models of infection. Rainbow trout Oncorhynchus mykiss maintained at 13 or 18°C were challenged by intracoelomic (ICe) injection with 101, 103 or 105 colony-forming units per fish (CFU fish-1) and monitored for 21 d.

The purpose of this study was to evaluate the protection conferred to rainbow trout () against by formalin-killed vaccines in immersion and injectable forms, as well as the enhanced protection afforded by booster vaccination. In the first challenge, fish were immunized via intracoelomic injection (IC) or immersion (Imm) routes alone.

Animals: 180 koi fish.
Procedures: Forty fish (shedders) were immersed in a 0.
Lactococcus garvieae is an emergent bacterial pathogen of salmonid fish in North America that causes acute infections particularly at water temperatures above 15°C. During 2020, L. garvieae was detected in rainbow trout, Onchorhyncus mykiss, cultured in Southern California and the Eastern Sierras.

- The study examines how gut bacteria may lead to urinary tract infections (UTIs) in kidney transplant recipients by analyzing fecal and urine samples.
- Findings indicate that a 1% abundance of the gut bacteria Escherichia and Enterococcus significantly increases the risk of bacteriuria and UTIs.
- The research suggests a direct connection between gut microbiota and UTI development, implying that changing gut bacteria could be a new approach to prevent these infections.
