Assessing knowledge and willingness to use genetically modified crops in Uganda

Background: There has been a lot of debate on genetically modified (GM) crops both globally and locally in Uganda. Whereas some of the debates have been informed by scientific research, many are not. The level of acceptance and attitudes of people towards GM crops is a function of their knowledge. However, there is a paucity of studies on the knowledge and attitudes of Ugandans on GM crops. This study aimed to assess the level of knowledge of GM crops in Uganda. Methods: We carried out a mixed methods study in September 2021 in Bushenyi, Jinja and Wakiso districts. We conducted 18 focus group discussions (FGDs), 13 key informant interviews (KIIs) and 698 quantitative interviews. The quantitative interviews were conducted using structured questionnaires. The FGD and KI interviews were audio recorded and transcribed verbatim. The qualitative data were analyzed using framework analysis and the quantitative data were analyzed using modified Poisson regression to identify factors associated with the level of knowledge of GM crops in STATA 15. Results: Out of the 698 respondents interviewed, only 273 (39.1%) had ever heard of GM crops. About 204 (74.7%) of the 273 respondents reported having a moderate–high understanding of GM crops and 62.3% (170) of the respondents further reported that GM crops are harmful to their health and environment, despite some of their intrinsic benefits, such as high productivity, improved income and resilience to pests and diseases. In addition, Out of the 698 respondents interviewed, only 37.7% were wary of the possibility of the emergence of super pests due to the development of resistance to some GM crops. Conclusions: Most of the community members do not have adequate knowledge about GM crops, hence, there is need for sensitization and legislation on GM crops before their release to the public

Human herpesviruses in the cornea

AIMS—To determine the sensitivity and specificity of culture, immunohistochemistry (IHC), the polymerase chain reaction (PCR), and in situ hybridisation (ISH) for detecting herpes simplex virus (HSV-1) in the cornea of patients undergoing penetrating keratoplasty. To compare the incidence of HSV-1 in the cornea with that of varicella zoster virus (VZV), cytomegalovirus (CMV), and Epstein-Barr virus (EBV).
METHODS—The corneas of 110 patients, 52 with a documented history of herpes keratitis (HSK) and 58 with non-herpetic corneal disease, were investigated using IHC, PCR, ISH, and culture.
RESULTS—HSV-1 DNA and antigen were detected in 82% and 74% respectively, of corneas of patients with HSK and in 22% and 15% of corneas of patients with no history of HSK. The sensitivity of PCR and IHC was 82% and 74% with a specificity of 78% and 85%, respectively. HSV-1 DNA and antigen were found more frequently and in increased amounts in corneas of patients with a short interval between their last attack of HSK and surgery. There was a good correlation between PCR and IHC in 71%. HSV-1 was isolated by culture in 2%. Latency associated transcripts were not detected using ISH. Evidence of VZV DNA or antigen was found significantly more frequently in the corneas of patients with a history of HSK (p<0.001). No evidence of EBV or CMV was found in any cornea.
CONCLUSIONS—PCR and IHC are both sensitive for the detection of HSV-1 in the cornea. A combination of PCR and IHC increases the specificity for the diagnosis of HSK to 97%. HSV-1 appears to be slowly removed from the cornea. VZV and HSV-1 may co-infect the cornea.
