Trypanosoma cruzi (Chagas disease) PCR for dogs

VRL announces that we now have T. cruzi PCR available for testing canine samples: T.cruzi PCR    Test Code 8540    Specimen Requirements: 1.0 ml-2.0 ml EDTA whole blood Chagas disease is a parasitic infection caused by T. curzi, which is transmitted by triatomid insect vectors to vertebrate hosts. Natural T.cruzi infection has been reported in humans, primates, live stocks, pets, rodents, etc.  Chagas disease is endemic in South America, Central America, U.S. and Mexico. Seroprevalence of T. cruzi in dogs is about 7.5-8.8% in Texas, U.S. The infection of T. cruzi in dogs causes nonspecific clinical signs, such as depression, lethargy, exercise intolerance, and increased heart rate. Some dogs may be asymptomatic and progressively develop heart failure in years.  The [...]

Fatal atypical O:3 Yersinia pseudotuberculosis infection in cynomolgus macaques.

Zao CL, Tomanek L, Hurtado-McClure G, Cooke A, Berger R, Boulineau TM, Turner OC, Covington DE.  Abstract Fatal Yersinia pseudotuberculosis infection in cynomolgus macaques was diagnosed based upon pathology, microbiology and PCR for this study. Pathological findings included acute, erosive to ulcerative, necrohemorrhagic enterocolitis. Genotyping by PCR showed an O:3 pattern (gmd-fcl(+), ddhC-prt(+), manB(+), ddhA-B(+)), but an additional gene, wbyK, was detected. This is the second report to identify wbyK+ O:3 genotype as the cause of fatal yersiniosis. The first case was reported in 2008, and involved farm deer in the U.S. As the frequency of wbyK+ O:3 genotype is found more often in different carriers, O:3 genotype [...]

Trypanosoma cruzi (Chagas disease) ELISA and PCR Available

VRL annouces that we now have T. cruzi ELISA and PCR available for our clients. cruzi ELISA (Order code L154): Specimen requirements: 0.5 – 1.0 ml serum cruzi PCR (Order code 8540): Specimen requirements: 1.0 – 2.0 ml EDTA whole blood Chagas disease is a parasitic infection caused by T. curzi, which is transmitted by triatomid insect vectors to vertebrate hosts. Natural T.cruzi infection has been reported in many non-human primates, including Macaca sp., a baboon, great apes, squirrel monkeys, owl monkeys, marmosets, tamarins, spider monkeys, woolly monkeys, cebus monkeys and uakaris. T. cruzi is commonly spread between monkeys in the wild by reduviid bugs, but it also can be spread in captive monkey [...]

Characterization of SRV-4 infected cynomolgus monkeys” is published in Arch Virol 2011; 156 (11): 2053-6

Virological and serological characterization of SRV-4 infection in cynomolgus macaques Zao CL, Ward JA, Tomanek L, Cooke A, Berger R, Armstrong K. The nature of SRV-4 infection in cynomolgus macaques remains unclear to date. Here, we report the monitoring of 24 cynomolgus monkeys that were naturally infected with SRV-4 for virus isolation, proviral load and antibody. The results indicated that the SRV-4 antibody status was statistically correlated to environmental temperature.

SRV-4 complete genome is published in Virology 2010; 405 (2): 390-6.

The complete Genome and Genetic Characteristics of SRV-4 Isolated from Cynomolgus Monkeys (Macaca fascicularis) Zao CL, Armstrong K, Tomanek L, Cooke A, Berger R, Estep JS, Marx PA, Trask JS, Smith DG, Yee JL, Lerche NW. At least 5 serotypes of exogenous simian retrovirus type D (SRV/D) have been found in nonhuman primates, but only SRV-1, 2 and 3 have been completely sequenced. SRV-4 was recovered once from cynomolgus macaques in California in 1984, but its genome sequences are unknown. Here we report the second identification of SRV-4 and its complete genome from infected cynomolgus macaques with Indochinese and Indonesian/Indochinese mixed ancestry. Phylogenetic analysis demonstrated that SRV-4 was [...]

SVV IgG Antibody Multiple Methodologies Available

VRL announces that we now have 3 methodologies available for our clients, for the detection of SVV (Simian Varicella Virus) IgG antibodies: SVV ELISA (Test code: L111; Specimen requirements: 0.5 – 1.0 ml serum) SVV IFA (Test code: F111; Specimen requirements: 0.5 – 1.0 ml serum) SVV DIA (Test code: 111; Specimen requirements: 0.5 – 1.0 ml serum) Simian varicella virus (SVV) causes an erythematous varicella-like disease in Old World monkeys.  SVV is closely related to varicella-zoster virus (VZV), which causes human varicella (chickenpox) in the primary infection and herpes zoster (shingles) in the reactivation stage. SVV is highly contagious and the transmission is through inhalation of aerosols [...]
