To determine whether batch solar disinfection (SODIS) can be used to inactivate oocysts of Cryptosporidium parvum and cysts Giardia muris in experimentally contaminated water.Suspensions were exposed simulated global irradiation 830 W m(-2) for different exposure times at a constant temperature 40 degrees C. Infectivity tests carried out using CD-1 suckling mice the experiments newly weaned experiments. Exposure > or =10 h (total optical dose c. 30 kJ) rendered noninfective. completely...
This work studies the influence of Neospora caninum intra-species diversity on abortion outcome, infection dynamics in terms parasite dissemination and peripheral-local immune responses pregnant cattle. Animals were intravenously inoculated at day 70 pregnancy with 10⁷ tachyzoites two isolates showing marked differences virulence vitro mouse models: Nc-Spain7, a high isolate, Nc-Spain8, low-to-moderate isolate. After inoculation, was monitored, dams culled when foetal death detected. Foetal...
Neospora caninum has been detected only sporadically in cases of ovine abortion, and it therefore traditionally considered as an unimportant parasite small ruminants. This study was carried out with the aim identifying pathogen causing serious reproductive problems on a commercial sheep farm. Sera from all rams ewes tested negative for antibodies against Border disease virus, Schmallenberg virus Coxiella burnetii, infections by these agents were ruled out. Nevertheless, seropositivity to N....
Endogenous transplacental transmission, which occurs during pregnancy as the result of reactivation a latent infection in dam, is main mechanism propagation Neospora caninum within cattle herds. However, importance this has not yet been evaluated relation to ovine neosporosis. In study, involving three generations ewes naturally infected by N. caninum, we demonstrated that endogenous transmission may also be highly efficient host since occurred 96.6% gestations and congenital rate ranged...
During the kidding season between January and April 2003, 10 farms were selected divided into two groups of five. The in group A had serious diarrhoeal illness losses neonatal kids previous year, there Cryptosporidium parvum infections associated with diarrhoea during survey. On B, was no history disease year neither C oocysts nor detected Faecal samples collected once from adult goats aged one seven years on each farm. To assess more accurately pattern output cysts Giardia duodenalis by...
Paramphistomosis caused by Calicophoron daubneyi and fasciolosis Fasciola hepatica are common parasitic diseases of livestock animals. Transmission the depends on presence intermediate hosts, i.e. freshwater gastropods such as lymnaeids. We carried out a 2-year-long study dynamics snail population acting host for these parasites, considering structure in terms size/age infection status. In addition, we determined kinetics trematode egg excretion grazing cows. Generalized Additive Models...
ABSTRACT The results of batch-process solar disinfection (SODIS) Cryptosporidium parvum oocysts in water are reported. Oocyst suspensions were exposed to simulated sunlight (830 W m −2 ) at 40°C. Viability assays (4′,6′-diamidino-2-phenylindole [DAPI]/propidium iodide and excystation) infectivity tests (Swiss CD-1 suckling mice) performed. SODIS exposures 6 12 h reduced oocyst from 100% 7.5% (standard deviation = 2.3) 0% 0.0), respectively.
Summary Faecal samples were collected from 734 cattle selected at random 60 dairy farms in Galicia (NW Spain). The animals studied classified into 12 age groups: <1 month (53); 1–5 months (30); 6–11 (31); 12–16 (72); 17–20 (64); 21–24 (96); 3 years (94); 4 (74); 5 (67); 6 7–8 (63) and 9–13 (23). Oocysts of Cryptosporidium spp. identified 104 (14.2%) distributed throughout all the groups 40 different (66.7%). percentage infected ranged between 58.5% calves 7.9% 7 to 8‐year‐old cows, i.e....
