Transmission dynamics study of tuberculosis isolates with whole genome sequencing in southern Sweden.

Epidemiological contact tracing complemented with genotyping of clinical Mycobacterium tuberculosis isolates is important for understanding disease transmission. In Sweden, tuberculosis (TB) is mostly reported in migrant and homeless where epidemiologic contact tracing could pose a problem. This study compared epidemiologic linking with genotyping in a low burden country.

Infection with Panton-Valentine leukocidin-positive methicillin-resistant Staphylococcus aureus t034.

Panton-Valentine leukocidin (PVL)-positive methicillin-resistant Staphylococcus aureus (MRSA), sequence type 398 is believed to be of animal origin. We report 2 cases of infection due to PVL-positive MRSA, spa type t034, in patients in Sweden who had had no animal contact.
