Streptococcus agalactiae (S agalactiae) is a germ habitually associated with infections in neonates and women during the pregnancy and the immediate puerperiumum. S. agalactiae has also been related with bacteriemias, endocarditis and bone, joint, skin and soft tissues infections in adults with concomitant diseases and even in immunocompetent patients. In the last years more than 70 cases of se...

A study was conducted to determine the role of specific antibodies in immunity to Streptococcus agalactiae. Adult Nile tilapia (Oreochromis niloticus) were injected i.p. with tryptic soy broth as control or with S. agalactiae vaccine. Ninety days later, fish were challenged with 1.5x10(4)CFUS. agalactiae fish(-1). Blood was drawn from all fish 90d after vaccination and 25d after challenge, and ...

Heme is essential for several cellular key functions but is also toxic. Whereas most bacterial pathogens utilize heme as a metabolic cofactor and iron source, the impact of host heme during bacterial infection remains elusive. The opportunist pathogen Streptococcus agalactiae does not synthesize heme but still uses it to activate a respiration metabolism. Concomitantly, heme toxicity is mainly ...

The isolation and characterization of two bacterial species, Streptococcus agalactiae and Lactococcus garvieae, previously unreported in wild marine mammals are described from a freshly dead bottlenose dolphin, Tursiops truncatus, from Kuwait Bay, Kuwait, in September 2001. Conventional and rapid identification systems were used to determine that isolates from muscle and kidney were S. agalacti...

Streptococcus agalactiae (S. agalactiae) is a major cause of invasive disease in neonates and pregnant women, but has also recently been observed among non-pregnant adults, especially elderly persons or persons with underlying chronic disease. S. agalactiae is also a rare cause of infective endocarditis, and most cases require early surgery. We report the case of a 43-year-old previously health...

Streptococcus agalactiae causes a range of clinical syndromes in camels (Camelus dromedarius). We report the genome sequences of two S. agalactiae isolates that induce abscesses in Kenyan camels. These genomes provide novel data on the composition of the S. agalactiae "pan genome" and reveal the presence of multiple genomic islands.

This paper aims to evaluate the efficiency of three inactive vaccines against contagious agalactia prepared with samples of Mycoplasma agalactiae isolated in Brazil and different adjuvants. Vaccine 1 adsorbed with aluminum hydroxide was administered in 23 goats (Gc1) and 13 sheep (Gov1); vaccine 2 containing Montanide IMS-2215-VG was administered in 22 goats (Gc2) and 12 sheep (Gov2) and vaccin...

Streptococcus agalactiae is the leading cause of bacterial sepsis and meningitis in neonates and also the causative agent of different serious infections in immunocompromised adults. The wide range of diseases that are caused by S. agalactiae suggests regulatory mechanisms that control the formation of specific virulence factors in these bacteria. The present study describes a gene from S. agal...

INTRODUCTION Streptococcus agalactiae is frequently an asymptomatic coloniser and a cause of neonatal and puerperal sepsis. Infections in nonpregnant adults are uncommon. The frequency of neurological complications caused by invasive infection with this microorganism in adults remains unknown. Here, we study the frequency and characteristics of central nervous system (CNS) involvement in adults...
