GENETIC DIVERSITY OF BOVINE DIARRHEA AND MUCOSAL DISEASE VIRUS

frame flanked by two untranslated regions (5’UTR and 3’UTR). The polyprotein is proteolytically cleaved by viral and host proteases resulting in the formation of mature viral proteins. It is well established that BVDV strains show considerable genetic diversity. BVD viruses are classified as two species: BVDV-1 and BVDV-2. Quite recently, a new putative species, BVDV-3, was detected. The viruses exist as one of two biotypes: cytopathic or non-cytopathic, based on their activity in cell

diversity, whereas MRSA outbreaks are usually caused by only a few different MRSA clones (Goering et al. 2008). Therefore, analyzing the genetic relatedness of colonizing MSSA strains in nursing homes might result in a better understanding of S. aureus epidemiology. We aimed at determining the genetic diversity and relatedness of MSSA and MRSA strains colonizing the upper respiratory tract of nursing home residents and staff using the MLVF (multiple-locus variable-number tandem-repeat fingerprinting

Genetic intraspecific diversity of Meloidogyne javanica parasitizing vegetables in southern Iran

methods for the identification species of RKNs are considerably time consuming and there is a lot of ambiguity, using species-specific primers could be a rapid method for detection (these primers listed in Cunha et al., 2018). The genetic diversity among M. javanica populations has been inferred by different markers (reviewed in Blok and Powers, 2009; Mokaram Hesar et al., 2011). Statistical analysis of the morphological characters and RAPD markers demonstrated 86 and 93% similarity among 21

Human platelet antigen allelic diversity in Peninsular Malaysia

) that inhabit Peninsular Malaysia. Combined with previous HPA data collected for Malay subethnic groups, Malays, Chinese, and Indians, our analyses showed high genetic diversity in Peninsular Malaysia, which is consistent with multiple settlements of the region by several founding ancestors (Semang, Senoi, and Proto-Malays) in the last 50,000 years. The gene pools of these ancient populations were then further shaped by various evolutionary pressures such as repeated founder effects, natural

Soil samples were submitted to one of us (JF), who extracted the nematode cysts and sent them to the USDA-ARS, Mycology and Nematology Genetic Diversity and Biology Laboratory (MNGDBL), Beltsville, MD for morphological and molecular identification. Cysts and second-stage juveniles (J2) conformed morphologically and morphometrically to V. zeaphila. We report here the first occurrence of this species in Indiana, thus representing the third state after Tennessee, and Kentucky in the United

of this species on grapevines in California, thus representing the second report of this nematode in North America. Materials and methods Two soil samples and grapevine roots were sent to the Mycology and Nematology Genetic Diversity and Biology Laboratory, Beltsville, MD in 2019. The origin of the soil samples was a vineyard from Mosca, Alamosa County, Co. Nematodes were extracted from soil using sugar centrifugal flotation and Baermann funnel methods. Nematodes were fixed in 3% formaldehyde

PARECHOVIRUSES – UNDERESTIMATED RISK

different types of HPeV (intertype recombination). Recombination contributes to the creation of new variants of the virus, and thus to the increase in the pace of evolution, it leads to the acquisition of genetic differences conditioning the change in virulence. European HPeV-1 isolates recombine on average every 1–3 years [42]. HPeV-3 rarely comes into contact with other parechoviruses in the same cell, hence the limited recombination and lower genetic diversity in comparison to HPeV-1 [10, 40, 98
