This study presents a Brazilian goat herd with reproductive failure over 2009-2010, in which there were abortions (22/50; 44%), embryonic resorption (6/50; 12%) and neonatal deaths (2/50; 4%). A diagnosis of leptospirosis was made, based on serology (microscopic agglutination test - MAT), bacterial culture, and polymerase chain reaction (PCR). Antibiotic(More)
The aim of the present study was to consider the wide usage of urinary PCR as an increasingly useful tool for an accurate diagnosis of leptospirosis in livestock. A total of 512 adult animals (300 cattle, 138 horses, 59 goats and 15 pigs), from herds/flocks with reproductive problems in Rio de Janeiro, Brazil was studied by serology and urinary PCR. From(More)
The effect of incident electrons on acetic acid clusters is explored for the first time. The acetic acid clusters are formed inside liquid helium nanodroplets and both cationic and anionic products ejected into the gas phase are detected by mass spectrometry. The cation chemistry (induced by electron ionization at 100 eV) is dominated by production of(More)
All over the world, leptospirosis has been reported as one of the major causes of reproductive failure in cattle and other ruminants, determining abortions, stillbirth, weak newborns and decrease in their growth rate and milk production. Nevertheless, despite its importance, it is still a challenging disease, from what scarce information about epidemiology,(More)
