Overview: Streptococcus agalactiae (also known as group-B streptococcus or beta-strep) is a Gram-positive coccus, non-motile, non-spore-forming, catalase-negative, spherical or ovoid, and less than 2 Âµm (micrometres) in diameter; it is usually Î²-haemolytic and can grow in pairs or short chains (Figure 1).his picture shows one of these tests. It is called the CAMP test. S. agalactiae infection is diagnosed using samples collected from blood, urine or spinal fluid.
