Identification of spp. in Slaughtered Sheep from Spain and Evaluation of Bradyzoite Viability after Freezing.

spp. are complex apicomplexan parasites that cause a substantial economic impact on livestock used for meat production. These parasites are present worldwide.

in meat of adult sheep in Spain.

Toxoplasmosis is a zoonotic disease caused by , an intracellular parasite that presents a worldwide risk. Humans can become infected by ingesting meat infected with , and the consumption of infected sheep and goat meat is a significant public health issue. Antibodies against have been found in sheep in Spain, indicating the presence of the parasite in the country.

Genotypic and phenotypic characterization of a Salmonella Typhimurium strain resistant to pulsed electric fields.

Pulsed Electric Fields (PEF) technology is regarded as one of the most interesting alternatives to current food preservation methods, due to its capability to inactivate vegetative microorganisms while leaving the product's organoleptic and nutritional properties mostly unchanged. However, many aspects regarding the mechanisms of bacterial inactivation by PEF are still not fully understood. The aim of this study was to obtain further insight into the mechanisms responsible for the increased resistance to PEF of a Salmonella Typhimurium SL1344 variant (SL1344-RS, Sagarzazu et al.

Comparative Study of Real-Time PCR (TaqMan Probe and Sybr Green), Serological Techniques (ELISA, IFA and DAT) and Clinical Signs Evaluation, for the Diagnosis of Canine Leishmaniasis in Experimentally Infected Dogs.

Canine leishmaniasis (CanL) diagnosis is not fully resolved. Currently, two specific methodologies are in continuous development, the detection of the parasite DNA or RNA in target organs and the detection of specific antibodies against sp. For a correct diagnosis, it has been shown that the joint use of this type of test is necessary.

Leptospira spp in Rodents from Peridomestic Sites in Endemic Regions of Nicaragua.

Leptospirosis is one of the most important zoonoses in tropical countries, including Nicaragua, where it is considered endemic. The aim of this study was to determine the frequency of Leptospira spp in rodents captured from peridomestic sites in leptospirosis endemic regions of Nicaragua. Using live traps, 191 rodents were captured in 2012 and 2013 between April and December.
