Acknowledgements 204 2011 Research Report i ii 2011 Research Report 1 Introduction Prof Cheryl de la Rey Message from the 1.1 Vice-Chancellor and Principal Research and the development of research capacity are defining features of the University of Pretoria’s vision and mission. Therefore, it is pleasing to report that in 2011 the University continued to make a significant contribution to the national research output of South Africa. In addition to the large number of publications reflected in this report, an especially pleasing outcome is that over 200 doctoral degrees were awarded; the highest number for any single South African university. 2 2011 Research Report In a developing country like South Africa, it is perhaps especially important that research activities at universities give focused attention to research training. The year 2011 showed continued growth in the enrolment and graduation of master’s and doctoral students. Close to a third of the University’s almost 45 000 contact students were postgraduates with approximately half of these were graduates of other universities, thus indicating that the University of Pretoria is a university of choice for postgraduate study. Creating an enabling environment for high-quality scholarship is of the utmost importance in the University’s strategy. By the end of 2011, the University had completed a number of major infrastructure developments, including a new Engineering Complex. (Engineering is one of the areas in which the University of Pretoria enjoys national and international prominence.) A new Knowledge Commons and Library Centre, partially funded by a grant from the Carnegie Corporation, was also officially opened in 2011. Almost immediately after opening, it became a hub for the growing numbers of postgraduate students. It is very pleasing to note that many of the University’s academics and postgraduate students distinguished themselves in 2011 by winning several awards and accolades. Notable too, is that there was a marked increased in the number of researchers rated by the National Research Foundation (NRF) and the proportion of high-impact publications increased. The achievements showcased in this report are due to the commitment and hard work of the University’s staff and students and I wish to express my sincere appreciation for their efforts in ensuring that the University of Pretoria continues to be counted among South Africa’s leading universities. On behalf of the entire University community, I also wish to thank Prof Robin Crewe, who was the Vice-Principal responsible for research and postgraduate studies for many years. Prof Crewe continues to provide outstanding leadership at the University as the Vice-Principal responsible for all faculties. Prof Stephanie Burton took office as Vice-Principal for Research and Postgraduate Education from April 2011. She has already demonstrated that she will make a marked contribution to the future success of the University. Thank you too to the many donors, sponsors and agencies who fund the University’s research through postgraduate scholarships, equipment and research grants. New large capital projects were funded in part by grants from the Department of Higher Education and Training and the Carnegie Corporation, and we are most grateful for these grants. Without additional support to complement the annual subsidy allocations from the Department of Higher Education and Training, the research outputs reflected in this report would not have been possible. By the end of 2011, the University Council had approved the University’s new long-term strategy, UP 2025, which will give increased impetus to ensuring that the University of Pretoria builds on its past achievements to make an even greater impact in the future. Prof Cheryl de la Rey Vice-Chancellor and Principal 2011 Research Report 3 Prof Stephanie Burton Message from the 1.2 Vice-Principal: Research and Post- graduate Education In offering an overview of research at the University of Pretoria during 2011, this report demonstrates the achievements of the University’s academic community and elucidates certain new developments. During 2011, the University continued to make a significant contribution to the total national research output and to improve the proportion of its research publications that are cited internationally. 4 2011 Research Report The University’s strategic plan, which has guided research since 2006, concluded at the end of 2011, and much attention was paid to the development of new strategic directions for research, which are aligned with the development of the broader academic plan that will take the University up to the year 2025. Renewed focus is being placed on the importance of research outputs in enhancing the international reputation of the University and on the need to expand its research productivity. The new developments in research at UP are reflected in this report, which highlights, among other features, the University’s progress in following the international trend of interdisciplinary research and addressing global challenges through the initiation of institutional and faculty research themes. These themes link multidisciplinary research groups through collaborative participation. The themes were developed on the basis of recognising and fostering excellence in research, and are led by recognised international leaders. They will contribute to the enhancement of the University’s research reputation by providing an enabling environment for the growth of scholarship among academic staff, postdoctoral fellows and postgraduate students. The University’s research makes excellent, internationally recognised contributions in the fields of veterinary science, agricultural and biological sciences, engineering and social sciences (as reflected in international databases), and its institutional research themes are aligned with these strengths in the focus areas of animal and zoonotic diseases, energy, food and nutrition, and genomics. The faculty research themes are based on specific areas of expertise, and include the control of malaria, molecular medicine, and international law. The University’s current research themes and the progress that has already been made are described in later sections of this report. Research at the University of Pretoria encompasses a very broad range of disciplines across its nine faculties and one business school, and more than 60 research institutes, centres and units. The Deans’ reports give accounts of the research highlights in each faculty,

A pair of oligonucleotide primers were designed according to the nucleotide sequence of the P18 gene of Babesia gibsoni (B. gibsoni), NRCPD strain, and were used to detect parasite DNA from blood samples of B. gibsoni-infected dogs by polymerase chain reaction (PCR). PCR was specific for B. gibsoni since no amplification was detected with DNA from B. canis or normal dog leucocytes. PCR was sensitive enough to detect parasite DNA from 2.5 µl of blood samples with a parasitemia of 0.000002%. PCR detected parasite DNA from 2 to 222 days post-infection in sequential blood samples derived from a dog experimentally infected with B. gibsoni. The detection of B. gibsoni DNA by PCR was much earlier than the detection of antibodies to B. gibsoni in blood samples by the indirect fluorescent antibody test (IFAT) or that of the parasite itself in Giemsa-stained thin blood smear film examined by microscopy. In addi- tion, 28 field samples collected from dogs in Kansai area, Japan, were tested for B. gibsoni infection. Nine samples were positive in blood smears, 9 samples were positive by IFAT and 11 samples were positive for B.

  • Babesia Infection in Dogs
    THE PET HEALTH LIBRARY By Wendy C. Brooks, DVM, DipABVP Educational Director, VeterinaryPartner.com Babesia Infection in Dogs Most people have never heard of Babesia organisms though they have caused red blood cell destruction in their canine hosts all over the world. Babesia organisms are spread by ticks and are of particular significance to racing greyhounds and pit bull terriers. Humans may also become infected. There are over 100 species of Babesia but only a few are found in the U.S. and are transmissible to dogs. Babesia canis, the “large” species of Babesia is one; Babesia gibsoni, a smaller Babesia that affects pit bull Babesia organism inside terriers almost exclusively is another; and a second but unnamed a red blood cell small Babesia has been identified in California. Babesia species continue to be classified and sub-classified worldwide. How Infection Happens and what Happens Next Infection occurs when a Babesia-infected tick bites a dog and releases Babesia sporozoites into the dog’s bloodstream. A tick must feed for two to three days to infect a dog withBabesia. The young Babesia organisms attach to red blood cells, eventually penetrating and making a new home within the cells for themselves. Inside the red blood cell, theBabesia organism divests its outer coating and begins to divide, becoming a new form called a merozoite that a new tick may ingest during a blood meal. Infected pregnant dogs can spread Babesia to their unborn puppies, and dogs can transmit the organism by biting another dog as well. (In fact, for Babesia gibsoni, which is primarily a pit bull terrier infection, ticks are a minor cause of infection and maternal transmission and bite wounds are the chief routes of transmission.) Having a parasite in your red blood cells does not go undetected by your immune system.

CRAVEN* and P VORSTER** Keywords: Namibia, phytogeography, plant endemism ABSTRACT Species richness, endemism and areas that are rich in both species and endemic species were assessed and mapped for Namibia. High species diversity corresponds with zones where species overlap. These are particularly obvious where there are altitudinal variations and in high-lying areas. The endemic flora o f Namibia is rich and diverse. An estimated 16% of the total plant species in Namibia are endemic to the country. Endemics are in a wide variety o f families and sixteen genera are endemic. Factors that increase the likelihood o f endemism are mountains, hot deserts, diversity o f substrates and microclimates. The distribution of plants endemic to Namibia was arranged in three different ways. Firstly, based on a grid count with the phytogeographic value of the species being equal, overall endemism was mapped. Secondly, range restricted plant species were mapped individually and those with congruent distribution patterns were combined. Thirdly, localities that are important for very range-restricted species were identified. The resulting maps of endemism and diversity were compared and found to correspond in many localities. When overall endemism is compared with overall diversity, rich localities may consist o f endemic species with wide ranges. The other methods identify important localities with their own distinctive complement of species. INTRODUCTION (1994). It was based on distributional data per magiste­ rial district following Merxmiiller (1966-1972), as well Species diversity was traditionally measured by count­ as other literature.

  • Canine Babesiosis – a Never-Ending Story
    No.4 July 2009 CVBD® DIGEST www.cvbd.org Canine babesiosis – a never-ending story Cutting-edge information brought to you by the CVBD® World Forum ® No.4 July 2009 CVBD DIGEST Canine babesiosis – a never-ending story Introduction When Bayer HealthCare, Animal Health Division, called for the 1st International CVBD® Symposium in 2006, it was the first and initial step to address the global threat of canine vector-borne diseases (CVBD®). This was based on the belief that vector-borne diseases of the dog should be treated as one topic and dealt with on a global level and in an interdisciplinary way. During the past years, CVBD® have become a global issue and have even sparked public interest. Many of the parasite-transmitted diseases affect humans as well as animals. The dog as man’s best friend plays an important role – as dogs serve as host for some of the zoonotic pathogens and are greatly affected by them. At the first symposium, the participants agreed to form the CVBD® World Forum. Besides gathering knowledge, the main task for this group of inter- national experts has been to raise awareness for the specific regional risks of CVBD® and to foster preventative measures. For this reason, the CVBD® World Forum created a website (www.cvbd.org) to provide the veterinary practitioner with cutting-edge and clinically relevant scientific information on CVBD®. In the CVBD® Digest, relevant findings from CVBD® symposia are presented perio di cally to veterinary practitioners. The Fourth International CVBD® Symposium has taken place, yet again reviving the intense discussion about the current trends and prospects.

  • Babesia Canis
    Q&A Babesia canis 1) What is Babesia canis? Babesia sp. are tick-borne protozoal parasites which infect red blood cells of mammals and can cause in some cases severe anaemia. Babesia canis specifically infects dogs. Other species of Babesia are host-specific and may infect livestock in which it is commonly known as piroplasmosis or red water fever. 2) Does this pose a human health risk? According to Public Health England Babesia canis is not considered to cause human disease and therefore does not present a risk to human health 3) How is the disease transmitted? Babesia parasites are generally spread by ticks although they can be spread by other means such as blood transfusions, contaminated veterinary equipment and possibly between dogs through fighting. Pregnant dogs can give Babesia canis to their unborn puppies (transplacental transmission). 4) How do dogs become infected? i. A dog could acquire the infection when living in, or travelling to, countries where B.canis occurs; ii. A dog could also acquire the infection in the UK from an infected tick that has been inadvertently brought into the UK. The Dermacentor tick species can be carried on other animals, including cattle, horses, sheep and pigs and the immature stages feed on small rodents. Unless the tick is removed by the dog’s owner and then destroyed, the infected tick continues the life cycle, laying eggs which may be infected and can develop into new infectious ticks. There is not direct dog to dog transmission with the same tick feeding on both animals; iii. A dog that has contracted B.
