Early Diagnosis and Treatment of Leptospirosis: Optimizing Clinical Outcomes
Introduction Leptospirosis is a globally prevalent cause of acute undifferentiated febrile illness (AUFI) that poses significant diagnostic challenges in its early stages. Based on a comprehensive systematic review of published studies and national databases from 34 countries, Costa et al. estimated that leptospirosis causes approximately 1.03 million cases and 58,900 deaths each year worldwide1.

THE END OF OIL IS IN SIGHT
A PUMPJACK IN L.A.’S WILMINGTON NEIGHBORHOOD. ACROSS CALIFORNIA, MORE THAN 5 MILLION PEOPLE LIVE NEAR AN OIL OR GAS WELL, TWO-THIRDS OF WHOM ARE PEOPLE OF COLOR. PHOTO BY NACHO CORBELLA Los Angeles is the largest urban oil field in the country. There are about 5,000 oil and gas wells in our backyards. Some are actively pumping oil, others are sitting idle, and others yet have been deserted by their operator, but all are emitting toxic pollutants into our air, water and soil.
EARTH DAY: KEEPING IT IN THE GROUND
Los Angeles is home to the Inglewood Oil Field, the largest urban oil field in the country. About 500,000 people in LA County live less than half a mile from an active oil well. We know oil and gas pollution are fueling global climate chaos and a local public health crisis. Unfortunately, we are now learning that those same airborne pollutants increase our risk of complications from COVID-19.

cis-Acting Determinant Limiting Expression of Sphingomyelinase Gene sph2 in Leptospira interrogans, Identified with a gfp Reporter Plasmid
ABSTRACT Many strains of the spirochete Leptospira interrogans serovar Pomona express the osmotically inducible sphingomyelinase gene sph2 at much higher levels than strains from other serovars. We developed a new green fluorescent protein (GFP) reporter plasmid to examine sph2 gene expression determinants. The vector enables the fusion of the test promoter to the ribosome-binding site and coding region of gfp. We fused the sph2 promoters from the L.
Identification of a cis-acting determinant limiting expression of sphingomyelinase gene sph2 in Leptospira interrogans with a gfp reporter plasmid
ABSTRACTMany Pomona strains of the spirochete Leptospira interrogans express the osmotically-inducible sphingomyelinase gene, sph2, at much higher levels than non-Pomona strains. We developed a new green fluorescent protein (GFP) reporter plasmid to examine sph2 gene expression determinants. The vector allows fusion of the test promoter to the ribosome-binding site and coding region of gfp.
