Abstract:

The aim of this thesis was to provide a picture of the trypanosomosis and drug resistance prevalence in Eastern Province of Zambia, to understand the underlying factors of drug resistance (drug use habits), to improve the diagnosis of trypanosomosis in livestock and finally, to improve the diagnosis of isometamidium resistance in T.congolense. After an introductory part where available trypanosomosis and trypanocide resistance diagnostic methods are described and discussed, the body of the thesis is divided in two main sections. In the first section are presented the results of a cross-section

Abstract:

The rise of antimicrobial resistance (AMR) has culminated in the most pressing problem in modern medicine. The situation is most acute with regards to the management of multi- drug resistant Gram-negative infections (MDRGNB) with common infections increasingly untreatable due to rapidly dwindling therapeutic options. A solution to the problem of AMR is unlikely to be easily found, but revisiting and re-purposing existing antimicrobials is a viable approach in the medium term. This study investigated the use of unorthodox antimicrobial combination therapies for the treatment of MDRGNB, with par

Abstract:

Resistance of human viral pathogens to various antiviral drugs is a serious medical problem. Two modes of drug resistance in cytomegalovirus infections have been observed, the first being altered (decreased) drug metabolism by the infected cells, and the second reduced sensitivity of the viral deoxyribonucleic acid polymerase enzyme to the active form of the drug. Mice infected with the murine cytomegalovirus have been used extensively as an animal model for the human cytomegalovirus, and drug-resistant strains in this model have been identified.

Clostridium difficile (C. difficile) is a gram positive, anaerobic, spore forming bacterium. C. difficile infections are triggered by dysbiosis of the intestinal microbiome linked to age, immune status, and medication; particularly use of antibiotics and proton pump inhibitors (PPI). The spore forming nature of the bacteria gives it the ability to persist in the environment for long periods of time and makes it impervious to many commonly-used hospital cleaning and disinfection products.

Mutations allowing for survival under antibiotic may not be beneficial when presented with the host environment or with a drug-free environment.

Abstract:

Emerging multidrug-resistant tuberculosis (MDR/XDR-TB) has become a major public health problem, placing millions at risk. Further, nosocomial transmission of MDR/XDR-TB places both patients and healthcare workers at an even higher risk. Effective tuberculosis (TB) infection prevention and control (IPC) policies in high-risk settings must use evidence-based science and should be customized to the setting. However, the growing incidence of MDR/XDR-TB in some global settings raises questions about whether adequate healthcare-related TB IPC policies are in place and whether they are implemented e

Abstract:

Mycobacterium tuberculosis (MTB) is an airborne pathogen that is easily transmitted from person to person. An intact immune system prevents the organism from causing disease in most individuals. In South Africa, the prevalence of human immunodeficiency virus (HIV) has reached astronomical levels and is now fuelling the tuberculosis (TB) epidemic. Drug resistant MTB strains combined with a weakened host immune system is a lethal combination. Multi-drug resistant (MDR) including extensively drug resistant (XDR) tuberculosis is on the increase, with Tugela Ferry in KwaZulu-Natal South Africa, rep

Abstract:

A total of 842 single patient isolates of Salmonella spp. from the New Territories East Cluster hospitals, Hong Kong, were collected during 2002 and 2004. The most common Salmonella enterica serotype isolated was S. Enteritidis (29.7%, 250 of 842) followed by S. Typhimurium (13.7%, 115 of 842). The remaining 29.6% (249 of 842) belonged to 44 serotypes and 27.1% (228 of 842) were non-typeable. The majority of isolates were from patients aged two years or younger and were isolated during June to October of each of the three years.

It is an opportunistic pathogen and often infects hospitalized patients who are severely ill or debilitated in intensive care units. It causes nosocomial infections, including pneumonia, meningitis, endocarditis, peritonitis, urinary tract infections, and bacteremia. The treatment for A. baumannii infections in the hospital is still based on antibiotics or in combination with a variety of antibiotics. However, in recent years drug-resistant A. b

The frequent misuse of antibiotics is one of the reasons behind the development of resistance in pathogenic strains of bacteria. Emergence of multidrug-resistant (MDR) strains of the Gram-negative gastric pathogen Helicobacter pylori (H. pylori) is a global health concern. H. pylori infection is highly prevalent, and has a strong association with various gastric diseases, including gastritis, digestive ulcers, and gastric cancer. Current
