The executive committee of the University of the Free State (UFS) has today resumed the training of its undergraduate students in the School of Clinical Medicine at the Pelonomi Hospital in Bloemfontein with immediate effect.

The decision to suspend the training of undergraduate students at the hospital came after the attempted rape of a medical intern last week, as well as the robbery of a medical officer in the parking area of the hospital over the weekend.

This morning, discussions involving the university management, the Head of the Department of Health (DoH) in the Free State Province, the executive committee of the Pelonomi Hospital, and the South African Police Service (SAPS) took place regarding the security situation at the hospital. The DoH provided the university with a security project plan comprising immediate and medium-term interventions, and a commitment to execute the plan as a matter of urgency. The university’s executive management furthermore met with the management of the Faculty of Health Sciences and, based on a safety risk assessment, the university’s executive management agreed that undergraduate students could again fully access the clinical platform at Pelonomi Hospital.

Interventions in the security project plan include the installation of high-mast lights in the precinct of the hospital, reparation of the perimeter fence, security locks, and limiting access to the hospital and the hospital grounds after 20:00 until 06:00. A Venue Operation Centre (VOC) made up of SAPS, institutional security management, and the Community Policing Forum will also be established at the hospital.

“The main focus and concern for the executive management of the university is the safety of its students and staff. We are satisfied with the security plan and the overall interventions committed to by the DoH and will monitor the implementation of these interventions with the management of the Pelonomi Hospital and the DoH. The security interventions will alleviate the situation at the hospital in order for the university to continue sending its undergraduate students there for training,” said Prof Francis Petersen, UFS Rector and Vice-Chancellor, during a media briefing today.

Prof Petersen also met with undergraduate students in the Schools of Clinical Medicine, Nursing, and Allied Health Professions today to discuss the situation at the hospital. Trauma counselling is provided to undergraduate students and staff and those in need of counselling at the Pelonomi Hospital.

The DoH has furthermore extended its bus service between the clinical platforms in Bloemfontein to students in need of transport of the School of Clinical Medicine according to time slots as from the beginning of the second semester. This service will ultimately be extended to undergraduate students in the Schools of Nursing and Allied Health Professions. “We will also look into further transport solutions for the longer term for our students,” said Prof Petersen.

Undergraduate students from the university’s Schools of Clinical Medicine, Nursing, and Allied Health Professions are trained on the clinical platforms in Bloemfontein – these include the Pelonomi Hospital, Universitas Hospital, National Hospital, the Mangaung University Community Partnership Programme (MUCPP), and the Free State Psychiatric Complex.

Although these clinical training platforms are under the jurisdiction of the DoH in the Free State Province, they form a critical part of the training of undergraduate students in the university’s Faculty of Health Sciences. Staff on the joint establishment of the UFS and the DoH also work at hospitals on the clinical platforms.

Research eradicates bacteria from avocado facility

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
