Abstract The article presents data on histopathological studies of the kidneys of cows, which either recovered or died from leptospirosis. Fragments of seven kidneys from slaughtered cows, positive for Leptospira antibodies in the microscopic agglutination test (MAT) (titres of 50 and higher) were used in the study. The MAT was conducted with eight serological groups of Leptospira: Canicola, Grippotyphosa, Hebdomadis, Icterohaemorrhagiae, Pomona, Sejroe, Tarassovi, and Australis. Microscopic changes in all morphological structures of the kidneys were presented. Micromorphological criteria, which can be used for post-mortem diagnosis of leptospirosis were established. They included: serous glomerulonephritis with granular dystrophy of podocytes, necrosis and collapse of the inner layer of Bowman's capsule, partial destruction of capsule and vascular glomeruli, granular and vacuolar degeneration and destruction of tubular epithelial cells, foci of interstitial oedema, and infiltrations predominantly with monocytes and isolated neutrophils. Microscopic changes in the kidneys suggest that the cows died from leptospirosis as a result of toxic shock syndrome.

The study was carried out with 73 human originated samples viz. surgical wound swab, pus, burn ulcer exudates, aural swab and diabetic ulcer exudates collected over a period of 5 months starting from September 2006 to identify and characterize enterotoxins and toxic shock syndrome toxin-1 (TSST-1) producing coagulase-positive S. aureus (CPSA) by Reverse Latex agglutination test, in which 30 (41.10%) were found as CPSA. Among the 30 CPSA isolates, 22 (73.33%), 6 (20%) and 2 (6.67%) were golden-yellow, yellow and whitish pigment producers, respectively and 29 (96.67%) isolates indicated β-hemolysis on blood agar speculating their ability to produce β-hemolysin. A total of 30 CPSA were checked for enterotoxin and TSST-1 production of which 5 (16.67%) and 1 (3.33%) isolates produced enterotoxin-A and TSST-1, respectively. Other produced multiple toxins in which 2 (6.67%) produced both enterotoxin A and enterotoxin B, 2 (6.67%) produced both enterotoxin C and enterotoxin D and 2 (6.67%) produced both enterotoxin C and TSST-1. Antibiotic resistant pattern of the CPSA indicated that 83.33% isolates were resistant to penicillin-G and 70% to sulphamethoxazole. On the other hand, the results demonstrated that gentamicin, spiramicin, ciprofloxacin, oxacillin, oxytetracycline and streptomycin might be used for the treatment of S. aureus infection. Few multiple antibiotic resistant CPSA were also identified. The prevalence of methicillin resistance S. aureus (MRSA) was 23.33%.

Abstract Neonatal toxic shock syndrome (TSS)-like exanthematous disease (NTED) is a syndrome first reported in Japan. Neonates develop systemic exanthema, thrombocytopenia, and fever usually during the first week of life. The disease is distinguished from frank TSS because affected infants are not severely ill and do not meet TSS criteria. Most infants are confirmed to be colonized with TSST-1 producing strains of S. aureus. Suggested diagnostic criteria for NTED include a skin rash with generalized macular erythema and one of the following symptoms: fever >38.0°C, thrombocytopenia <150 x103uL, or low positive C-reactive protein (1-5 mg/dL) in the absence of another known disease process. NTED is common in Japanese NICUs, but outside Japan, only one case has been reported in France. We describe the first case of NTED reported in North America.
