Infections involving Echinostoma hortense (E. hortense) are considered to more severe than infections caused by other heterophyids. Although parasite expulsion by host immune responses attenuates the symptoms of infection, the detailed mechanisms of the host immune response need to be determined, especially in local immune responses involving cytokine and immunoglobulin expressions. We infected BALB/c mice with E. hortense and examined recovery rates together with expressions of multiple cytokines and immunoglobulins in the villi and crypts of the small intestine using immunohistochemistry. We observed a close correlation between worm expulsion rates and cytokine/immunoglobulin expressions in E. hortense infected mice. This study contributes to an understanding of the relationship between the immune response and parasite expulsion in hosts.

Bacterial infection after implant installation or bone graft is a serious complication. Bone grafts represent a temporary foreign body lacking vascularisation and are therefore of increased susceptibility to infection, which may be introduced either intraoperatively or postoperatively. Bone graft-associated infections are due to biofilm formation on the surface of the bone graft and often require removal of the infected bone graft with substantial graft failure. In this review, the implant and graft related infection, the role of biofilm and the management will be discussed.

Over 100 million people worldwide are chronic carriers of hepatitis C virus (HCV)(1). Chronic viral infections of the liver can prouess to cirrhosis, which may ultimately lead to hepatic failure or the development of hepatocellular carcinoma. There are a limited number of antiviral drugs on the market approved fur clinical management of chronic HCV infections; interferon-alpha (IFN$\alpha$) and the nucleoside analog ribavirin. However, whether used as monotherapy or in combination, adverse side-effects are associated with each drug and better therapeutic regimens are needed. (omitted)

Herpes virus family is highly infectious to patients, their families and dentists. The diagnosis of herpes infection is based on the characteristic clinical appearance and the location of the lesions. Herpes Simplex Virus(HSV) usually acquired through direct contact with infected lesions or body fluids, and the prevalence of HSV infection increases progressively from childhood. Primary infections provoke herpetic gingivostomatis typically affects the tongue, lips, gingival, buccal mucosa and palate. Recurrent infections give rise to vesiculo-ulcerative lesions at vermilion border of lip(herpes labialis). In the form of chickenpox, Varicella Zoster Virus(VZV) usually is infected in childhood. VZV spreads in the affected primary afferent nerve to the skin and produces a vesicular rash and pain. Epstein-Barr Virus(EBV) infects B cells and cause infectious mononucleosis. Latent EBV infection has also been implicated in Burkitt lymphoma, nasopharyngeal carcinoma. Cytomegalovirus(CMV) is associated with immune-compromised patient such as organ transplantation and AIDS patients.

Cronobacter species have been associated with disease outbreaks and sporadic infections, particularly in premature and immunocompromised infants. Cronobacter species can cause foodborne infections such as neonatal meningitis, septicaemia and necrotising enterocolitis. Accordingly, there is an urgent need to control and monitor the Cronobacter species in food, especially in powdered infant formula (PIF) and other baby foods. Therefore, in this review, the isolation and prevalence of Cronobacter species in infant food including PIF and the recent advance of detection methods are discussed for the better understanding on the current research status of Cronobacter species.

Of many viral causes of human cancer, few are of greater global importance than the hepatitis B virus (HBV). Over 250 million people worldwide are persistently infected with HBV. A significant minority of these develop severe pathologic consequences, including chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC). Earlier epidemiological evidence suggested a link between chronic HBV infection and HCC. Further, the existence of related animal viruses that induce acute and chronic infections of the liver, and eventually HCC, confirms the concept that HBV belongs to one of the few human oncogenic viruses. Although it is clear that chronic HBV infections are major risk factors, relatively little is understood about how the viral factors contribute to hepatocarcinogenesis. This review will introduce molecular aspects of the viral infection, and highlight recent findings on the viral contribution to hepatocarcinogenesis.

Neutrophil gelatinase-associated lipocalin (NGAL) has emerged as one of the most promising biomarkers of renal epithelial injury. Numerous studies have presented the diagnostic and prognostic utility of urinary and plasma NGAL in patients with acute kidney injury, chronic kidney disease, renal injury after kidney transplantation, and other renal diseases. NGAL is a member of the lipocalin family that is abundantly expressed in neutrophils and monocytes/macrophages and is a mediator of the innate immune response. The biological significance of NGAL to hamper bacterial growth by sequestering iron-binding siderophores has been studied in a knock-out mouse model. Besides neutrophils, NGAL is detectable in most tissues normally encountered by microorganisms, and its expression is upregulated in epithelial cells during inflammation. A growing number of studies have supported the clinical utility of NAGL for detecting invasive bacterial infections. Several investigators including our group have reported that measuring NGAL can be used to help predict and manage urinary tract infections and acute pyelonephritis. This article summarizes the biology and pathophysiology of NGAL and reviews studies on the implications of NGAL in various renal diseases from acute kidney injury to acute pyelonephritis.

Mixed infections of Plasmodium falciparum and Plasmodium vivax is high (~ 30%) in some malaria hypoendemic areas where the patients present with P. falciparum malaria diagnosed by microscopy. Conventional treatment of P. falciparum with concurrent chloroquine and 14 days of primaquine for all falciparum malaria patients may be useful in areas where mixed falciparum and vivax infections are high and common and also with mild or moderate G6PD deficiency in the population even with or without subpatent vivax mixed infection. It will be possibly cost-effective to reduce subsequent vivax illness if the patients have mixed vivax infection. Further study to prove this hypothesis may be warranted.
