This study was a retrospective analysis of 41 patients with late prosthetic graft infections (> 30 days after operation) from six hospitals in the south-west of England. The 41 patients had a median age of 66 years and generally accepted risk factors for infection were documented in 19 patients preoperatively. Thirteen patients had postoperative wound complications and three had early reoperation at the site of subsequent infection. The median time between index operation and symptoms of infection was 10 (range 1–224) months. Abscess (46%) was the most common presentation followed by false

Abstract:
Postpartum uterine infections such as metritis, endometritis and mastitis have been considered as underlying causes for ovarian dysfunction in mammals. Almost all mammals, particularly dairy animals are susceptible to postpartum uterine infections, resulting in impaired fertility and economic loss. One of the factors for low fertility in females is ovarian dysfunction, which is exhibited as impaired growth and function of ovarian follicles by the postpartum infection. Immune system of mammals provides a host defence mechanism against pathogenic microbes through the recognition of pathogen-asso

Abstract:
Acinetobacter baumannii is a bacterium that is commonly causes of nosocomial infections, the most common site of infection and colonization is the lower respiratory tract. Although it is present more often in immunocompromised patients, the defense mechanism against infection with Acinetobacter baumanii remains incomplete elucidated. Among the virulence factors involved in infection with Acinetobacter baumanii are production and release of exopolysaccharide, and ability to biofilm formation in tissues. Understanding of virulence mechanisms is important for early initiation of treatment.

Abstract Persistent viral infections are associated with dysfunctional B cell responses including polyclonal B cell activation, non-virus-specific hypergammaglobulinemia, and ultimately the inability to control infection. Using the lymphocytic choriomeningitis virus (LCMV) system of murine infection, we addressed whether similar to other antiviral mechanisms, the suppressive immune environment generated during persistent infection impacted antibody effector function. We demonstrate that high levels of circulating antibodies generated during persistent infection (termed hypergammaglobulinemia)

The co-infection of Mycobacterium tuberculosis (MTB) and HIV continues to pose a major challenge to healthcare systems. Currently, the effects of HIV infection on tuberculous granulomas are not fully understood.

The co-infection results in atypical granulomas with weakened immune defenses, which facilitate the dissemination of MTB and accelerate the progression of tuberculosis. Additionally, thi

Abstract Hepatitis viral infection can cause severe complications, even mortality in pregnant women and their offspring. Multiple studies have shown that vertical transmission can cause viral hepatitis infections in newborns, especially in hepatitis B, C, and E. Screening for hepatitis viral infection in pregnant women is essential. Once infected, pregnant women should be given timely antiviral treatments, which could effectively alleviate the disease progression and reduce adverse outcomes. Besides, the mechanism of viral hepatitis mediating adverse pregnancy outcomes has been a hot topic. He

Since their 'discovery' at the turn of the 21st century, giant viruses of the amoeba have captured the fascination of virologists. They have raised a plethora of questions regarding their evolution and ecological significance and have greatly defied a century's old definition of viruses. By now, it is understood that a handful of giant viruses enter the amoeba via the phagosomal pathway. This thesis chooses to focus on the giant Melbournevirus (MelV) regarding its entry and uncoating pathway.

Although over 200 types of HPV have been identified which can infect humans, only around 15 high-risk (HR) types have been shown to be responsible for the development of cancer. HPV-16 is the most abundant HR-HPV type being responsible for almost 70% of cervical cancers. HPV-16 consists of 8 genes, the early genes (E1, E2, E4, E5 and the potential oncogenes E6 and E7) responsible for the infection, amplification and proliferation and the late genes (L1 and L2) responsible for the packaging and

This thesis describes an investigation of the mechanisms by which DC-SIGN mediates enhancement of HIV-1 infection.

DC-SIGN mediates both productive infection of DCs and trans-infection of CD4+ T cells that occurs in the absence of replication.

Abstract:
The Israeli isolate of Tomato yellow leaf curl geminivirus (TYLCV-Is) is a major tomato pathogen, causing extensive (up to 100%) crop losses in Israel and in the south-eastern U.S. (e.g., Georgia, Florida). Surprisingly, however, little is known about the molecular mechanisms of TYLCV-Is interactions with tomato cells. In the current BARD project, we have identified a TYLCV-Is protein, V2, which acts as a suppressor of RNA silencing, and showed that V2 interacts with the tomato (L. esculentum) member of the SGS3 (LeSGS3) protein family known to be involved in RNA silencing.

Abstract:
Tomato yellow leaf curl virus (TYLCV) is a major pathogen of tomato that causes extensive crop loss worldwide, including the US and Israel. Genetic resistance in the host plant is considered highly effective in the defense against viral infection in the field. Thus, the best way to reduce yield losses due to TYLCV is by breeding tomatoes resistant or tolerant to the virus. To date, only six major TYLCV-resistance loci, termed Ty-1 to Ty-6, have been characterized and mapped to the tomato genome. Among tomato TYLCV-resistant lines containing these loci, we have identified a major recessive quan

Abstract:
Orobanche is an important parasitic weed. For developing novel methods for its control, a thorough understanding of crucial stages of its development is needed. Therefore, the objectives of this project were characterization of Orobanche germination stimulants, analysis of mechanisms of haustorial penetration, and characterization and isolation of penetration enzymes. The first highly potent natural germination stimulant for Orobanche was isolated from sunflower and identified by high-field 1D (1H and 13C), 2D (1H-1H COSY, HMQC, HMBC)-NMR, GC.FT-IR, and GC.MS as costuslactone, a guaiane type s

Abstract:
Mycoplasma bovis and M. agalactiae are two phylogenetically related mycoplasmas which cause economically significant diseases in their respective bovine or small ruminant hosts. These organisms cause persistent asymptomatic infections that can result in severe outbreaks upon introduction of carrier animals into susceptible herds. Little is known about the mechanisms underlying mycoplasma-host interaction, variation in virulence, or of the factors enabling avoidance of the host immune system. In recent years it has become apparent that the ability of pathogenic microorganisms to rapidly alter s

Abstract:
The mechanisms underlying the development of symptoms in response to virus infection remain to be discovered in plants. Insight into symptoms induced by potyviruses comes from evidence implicating the potyviral HC-Pro protein in symptom development. In particular, recent studies link the development of symptoms in infected plants to HC-Pro's ability to interfere with small RNA metabolism and function in plant hosts. Moreover, mutation of the highly conserved FRNK amino acid motif to FINK in the HC-Pro of Zucchini yellow mosaic virus (ZYMV) converts a severe strain into an asymptomatic strain,

In this study, we investigated neuroinfectious capacity of H5N1 (A/Thailand/NK165/2005) isolated from plasma of infected individual during the third wave of Thailand outbreaks using human neuroblastoma SH-SY5Y cells. This was due to lack of information regarding neuroinfectivity of this variant. Results demonstrated that H5N1/NK165 induced servere CPEs in these neuronal cells. H5N1-specific hemagglutinin was found in the cytoplasm of the infected cells as early as 12 h post-infection. By 24 h post-infection, all cells in the cultures were infected. These findings coincided with time course of

Abstract:
RNA silencing is a defense mechanism that functions against virus infection and involves sequence-specific degradation of viral RNA. Diverse RNA and DNA viruses of plants encode RNA silencing suppressors (RSSs), which, in addition to their role in viral counterdefense, were implicated in the efficient accumulation of viral RNAs, virus transport, pathogenesis, and determination of the virus host range. Despite rapidly growing understanding of the mechanisms of RNA silencing suppression, systematic analysis of the roles played by diverse RSSs in virus biology and pathology is yet to be completed
