Spatial and temporal epidemiology of bovine trichomoniasis and bovine genital campylobacteriosis in La Pampa province (Argentina).
The venereal diseases bovine trichomoniasis (BT) and bovine genital campylobacteriosis (BCG) cause economic losses in endemic areas like La Pampa province in Argentina, where beef cattle are usually managed extensively. This study used data compiled under a Provincial Programme for the Control and Eradication of BT and BGC (PCE) to determine the spatio-temporal distribution of these diseases an...
متن کاملPresence of antibodies against Leptospira serovars in Chaetophractus villosus (Mammalia, Dasypodidae), La Pampa province, Argentina.
Leptospirosis is a zoonosis of worldwide distribution. The aim of this study was to examine the presence of antibodies against 21 Leptospira reactive serovars in Chaetophractus villosus in La Pampa province, Argentina, using the microscopic agglutination test (MAT). Pathologic changes compatible with leptospirosis and in situ detection of the agent by immunohistochemistry were studied in 24 and...
متن کاملPrevalence and spatial distribution of bovine brucellosis in San Luis and La Pampa, Argentina
BACKGROUND Bovine brucellosis (BB) is a zoonotic disease caused by Brucella abortus. BB is endemic in Argentina, where vaccination with Brucella abortus strain 19 is compulsory for 3-to-8 month-old heifers.

متن کاملArsenic contamination of natural waters in San Juan and La Pampa, Argentina.
Arsenic (As) speciation in surface and groundwater from two provinces in Argentina (San Juan and La Pampa) was investigated using solid phase extraction (SPE) cartridge methodology with comparison to total arsenic concentrations. A third province, Río Negro, was used as a control to the study. Strong cation exchange (SCX) and strong anion exchange (SAX) cartridges were utilised in series for th...
متن کاملVegetation disturbance by fire affects plant reproductive phenology in a shrubland community in northwestern Patagonia, Argentina
Reproductive phenology is likely to vary spatially with environmental conditions that alter microclimate, in particular temperature. We hypothesized that within the same plant community type, environmental changes produced by recent burning would alter plant phenological patterns and temporal structure of the plant community. Specifically, we predicted accelerated flowering and fruiting dates i...
