In this task, you're given a paragraph from the research paper and your task is to generate a suitable title for the research paper based on the given paper. Under 100 words is a good title length.

Q: Ten strains of avian infectious bronchitis virus (IBV) were titrated as plaqueforming units in primary chick embryo fibroblast cells. In the absence of trypsin, plaques were only formed by Beaudette-42 and Iowa-609 strains. When trypsin was incorporated in the overlay medium of cell monolayers, all the IBV strains tested produced plaques within 4days after inoculation. Incorporation of 20--40 ~xg of trypsin per ml of the overlay medium seemed to be suitable for plaque formation of IBV. A preliminary investigation was made of the mode of action of trypsin.

Q: Diarrhea outbreaks in pig farms have raised major concerns in Europe and USA, as they can lead to dramatic pig losses. During a suspected outbreak in Belgium of porcine epidemic diarrhea virus (PEDV), we performed viral metagenomics to assess other potential viral pathogens. Although PEDV was detected, its low abundance indicated that other viruses were involved in the outbreak. Interestingly, a porcine bocavirus and several enteroviruses were most abundant in the sample. We also observed the presence of a porcine enterovirus genome with a gene insertion, resembling a C28 peptidase gene found in toroviruses, which was confirmed using re-sequencing, bioinformatics, and proteomics approaches. Moreover, the predicted cleavage sites for the insertion suggest that this gene was being expressed as a single protein, rather than a fused protein. Recombination in enteroviruses has been reported as a major mechanism to generate genetic diversity, but gene insertions across viral families are rather uncommon. Although such inter-family recombinations are rare, our finding suggests that these events may significantly contribute to viral evolution.

Q: Small and medium-sized tourism and hospitality enterprises (SMTHEs) are often susceptible to various hazards, which result in risk concerns. Insurance is recognised as one of the risk management strategies, but evidence indicates that insurance uptake among SMTHEs has been low. Yet, researchers have hardly researched into the factors that influence insurance uptake among SMTHEs. Two-hundred and fifty (250) respondents were selected using a multi-stage sampling technique. Confirmatory factor analysis, multivariate logit and probit regression techniques were used to determine factors underlying SMTHEs' insurance uptake. Risk concerns, the firm's characteristics, the perceived benefits of insurance and other informal risk coping mechanisms, as well as insurance service provision concerns were identified as determinants of insurance uptake. This is one of the first papers to offer a holistic understanding of the factors influencing SMTHEs' insurance subscription in a resourcescarce destination of Sub-Saharan Africa. The practical and theoretical implications of the paper are discussed.
