Bovine parvovirus and bovine enterovirus in mixed infections
… the events occurring when DNA and RNA viruses mixedly infect single cells. The objectives of this research were threefold. First, to determine the effects of single infection of synchronized bovine fetal spleen cells by bovine parvovirus and bovine enterovirus on cellular macromolecular …

Mixed infections of maize dwarf mosaic virus and cucumber mosaic virus in maize
… mosaic (MDMV) and cucumber mosaic virus (CMV). A mixed infection of these two viruses could be maintained in maize plants grown under laboratory conditions. The possibility of synergism or of an interference mechanism between MDMV and CMV in dual infections was investigated and it was found that …

Developing a single dressing containing both antifungal and antibacterial drugs for treating mixed infections in diabetic foot ulcers
… for the National Health Service and are prone to infections. Mixed bacterial-fungal infections are more complicated than single microbe infections with enhanced severity of DFUs. Moreover, recently developed medicated dressings target only either bacterial or fungal infection. This study therefore …

Detection of mixed Mycobacterium tuberculosis infections in South African TB Patients
… heightened immune protection against subsequent infections, has been revised. Epidemiological studies and the advances in molecular genotyping techniques have highlighted the rapidly frequent isolation of several different M. tuberculosis strain lineages in single disease episodes, often with …

Molecular characterization of trypanosomes commonly found in cattle, wild animals and tsetse flies in Kwazulu-Natal, South Africa, 2005-2007
… The two species were found as single and as mixed infections in cattle. There are two genotypic groups of T. congolense in KZN; the Savannah- and the Kilifi-type. The two genotypic groups were found as mixed infections in cattle and in tsetse flies. Lastly, there are at least five “genomic …

Geographic distributions and vertebrate host specificity of genetic lineages of Borrelia burgdorferi
… in vertebrate hosts. In fact, B. burgdorferi infections that disseminate across host tissues in humans are associated with only a subset of ospC alleles. Delaware has a high incidence of Lyme disease, but the diversity of ospC in B. burgdorferi in the state has not been evaluated. We used PCR …

Genes and structural proteins of the phage SYN5 of the marine cyanobacteria, Synechococcus
… gene transfer, mediated through lysogeny, mixed infections, pseudolysogeny, and transduction.

Evolutionary studies of wheat streak mosaic-associated viruses and characterization of the wheat virome
… WSM, TriMV and HPWMoV have also been reported in mixed infections. While resistant varieties are utilized to minimize the effects of the disease, genetic variation in associated viruses increases the emergence of potential resistance-breaking isolates. Currently, little is known about the genetic …

Analysis of two hypervariable human cytomegalovirus genes, UL146 and UL139
… other forms of post translational modification. Mixed infections of HCMV strains in immunocompromised individuals, such as transplant recipients, have been associated with enhanced pathogenesis and increased risk of transplant rejection. The presence of mixed infections also further complicates …

Mixed Strain Identification of Porcine Reproductive and Respiratory Syndrome Virus in Multiplexed Samples using Nanopore Sequencing
… pair and sequencing technique have distinguished mixed infections within individual animals and may be used to determine vaccination status. This new approach will help producers and veterinarians make better-informed decisions about co-mingling of animals and vaccination strategies, thus reducing …

Characterization of influenza A virus evolution in laboratory hosts
… in ECEs and MDCKs, and during ten serial infections in ECEs. The results from these experiments indicate that there is a wide range in the number of sequence differences between pre- and post-passaged viruses, and that sequencing viruses prior to passage results in better identification of …

Plant virus detection and diversity in a mixed tree fruit orchard determined through metagenomic-based analysis of honeybee (Apis mellifera) collected samples
… accumulate various viruses, leading to complex mixed infections. Furthermore, emerging viruses can create epidemics causing significant losses. Effective monitoring approaches can reduce these impacts through management practices. Pollination is an essential aspect of fruit production, and …

Differential diagnosis of nematode ova in cattle
… reported with increasing frequency parasitic infections in cattle in the State of Virginia. Hence, the Animal Husbandry Department in conjunction with the Animal Pathology Department of the Virginia Polytechnic Institute initiated in the Autumn and Spring of 1953-1954 a survey in the State to …

Prevalence and risk factors associated with Trypanosomosis in Cattle Herds in Kilwa District of Lindi Region of Tanzania
… CI: 12.3-29.7). Most of the cattle herds had mixed infections of these parasites. According to LAMP, Miteja and Matandu villages both had the highest AAT prevalence of 57% (95% CI: 20.3-93.7) while Mavuji had the lowest prevalence of 14% (95% CI: 0-39.7). Data from the present study suggest …

Molecular diagnostics, genetic diversity and generating infectious clones for cassava brown streak viruses
… and ideal for resource-poor laboratories. Mixed infections of cassava mosaic begomoviruses (CMBs) that cause cassava mosaic disease (CMD), CBSV and CBSUV have become more common with the recent spread of CBSD at mid-altitudes. A multiplex PCR for the simultaneous detection of viruses that …

The Effect of Within-host Virus Population Growth and Interspecific Competition on Aphid Transmission and Population Structure of Barley Yellow Dwarf Virus
… of competitive interactions between species in mixed infections. In singly infected plants, PAS population size was 20% greater than that of PAV at 8 days post inoculation (DPI), but by 33 DPI the population size of PAV was 10% greater than that of PAS. In doubly infected plants, by 33 DPI the …

Genetic characterisation and phylogenetic analysis of bovine astroviruses and kobuviruses
… of one single KoV detected among possible mixed infections. Upon assembly of the genome sequences, some animals were found to be co-infected with multiple KoVs. The main region of diversity, the VP1 (capsid) region, was amplified from multiple samples to determine the diversity of KoV in …
