Helicobacter (H.) pylori infection is an important risk factor for gastric cancer that causes gastric inflammation. Inflammatory chemokines such as interleukin (IL)-8 and regulated on activation normal T cell expressed and secreted (RANTES) are elevated in the gastric mucosa by H. pylori. This study aimed to investigate the effects of Lactobacillus paracasei strain 06TCa19, a probiotic strain, on IL-8 and RANTES expression and production induced by H. pylori using human gastric epithelial cell lines. Strain 06TCa19 was shown to suppress H...

Transmission of infectious agents might be associated with iatrogenic actions of charitable help in health care. An example is the vaccination against yellow fever in USA that transmitted hepatitis B virus. Another example is injections of praziquantel for treatment and cure of schistosomiasis in Central and Northern Africa, with a focus in Egypt that has spread hepatitis C virus. There is no indication that human T-lymphotropic virus type 1 was spread by injection treatment for African trypanosomiasis, syphilis and treponematosis, but these treatments might have contributed to the early spread of human immunodeficiency virus type 1 (HIV-1) in Central Africa...

The proper management of pregnant women infected with hepatitis B virus (HBV) is necessary to prevent maternal and fetal morbidity and mortality and to protect the baby from HBV infection. In the majority of cases, vertical transmission can be prevented with a universal screening program, HBV vaccine immunoprophylaxis, and administration of hepatitis B immunoglobulin (HBIg) for babies born to mothers with HBV. However, in mothers with a high viral load (>200,000 or >1,000,000 IU/ml, depending on the guideline), the chance of immunoprophylaxis failure remains high...

Salmonid alphavirus (SAV) infection has led to the spread of salmon pancreas disease (PD) and sleeping disease (SD) to salmonids in several countries in Europe, resulting in tremendous economic losses to the fish farming industry. Recently, with increases in the fish import trade, many countries in which SAV has been unreported, such as China, may be seriously threatened by these diseases. It is therefore necessary to develop efficient detection methods for the prevention and diagnosis of SAV infection. In this study, a rapid and sensitive TaqMan real-time PCR method was established and assessed for this purpose...

In this study, pacu (Piaractus mesopotamicus) were fed with diets containing Aloe vera for 10 days prior to transport stress and infection with heat killed Aeromonas hydrophila. A. vera is popular around the world due to its medicinal properties, including immunostimulatory effects which was observed in this study. The results show that transport causes immunosuppression, an effect that was prevented by A. vera. Specifically, A. vera prevented reductions of both leukocyte respiratory burst and hemolytic activity of complement system caused by transport...

Maternal immunisation has the potential to substantially reduce morbidity and mortality from infectious diseases after birth. The success of tetanus, influenza, and pertussis immunisation during pregnancy has led to consideration of additional maternal immunisation strategies to prevent group B streptococcus and respiratory syncytial virus infections, among others. However, many gaps in knowledge regarding the immunobiology of maternal immunisation prevent the optimal design and application of this successful public health intervention...

BACKGROUND: The diagnosis of toxoplasmosis in pregnant women during the early first trimester of pregnancy is very important for preventing congenital infection of the fetus; it will not only prevent the risk of transmitting the infection to the fetus but it will also enable to give these women a preventive treatment. In this study, the avidity test was performed on pregnant women during their first prenatal visit at the National Institute of Hygiene in Rabat, Morocco. FINDINGS: One hundred and twenty-eight sera samples were collected from 128 pregnant women between august 2015 and June 2016; these women were chosen retrospectively and were in their first 4 months of pregnancy...

Echinococcosis is a parasitic zoonosis that is considered as a neglected disease by the World Health Organization. The species Echinococcus oligarthrus is one of the causative agents of Neotropical echinococcosis, which is a poorly understood disease that requires a complex medical examination, may threaten human life, and is frequently associated with a low socioeconomic status. Morphological and genetic diversity in E. oligarthrus remains unknown. The aim of this work is to identify and characterize E. oligarthrus infections in sylvatic animals from the Upper Paraná Atlantic Forest in the province of Misiones, Argentina, by following an integrative approach that links morphological, genetic and ecological aspects...

Wilson disease leads to symptomatic impairment of liver function or liver cirrhosis. Strict adherence to decoppering agents is essential in these patients. Secondary prevention of additional hepatic damage by avoidance of other toxic substances (e.g., alcohol, drugs) and sufficient calorie intake is recommended. Routine examinations in cirrhotic patients include screening for signs of portal hypertension (esophagus varices), development of ascites, and hepatic encephalopathy. Where varices are present, primary or secondary preventive interventions may include treatment with nonselective beta-blockers or variceal ligation, similar to the approach in patients with liver cirrhosis due to other etiologies...

Rotavirus is the leading worldwide cause of gastroenteritis in children under five years of age. Even though there are some available vaccines to prevent the disease, there are limited strategies for challenging diarrhea induced by rotavirus infection. For this reason, researchers are constantly searching for other approaches to control diarrhea by means of probiotics. In order to demonstrate the ability of some probiotic bacteria to interfere with the in vitro rotavirus infection in MA104 cells, strains of Lactobacillus sp...

Ocular infection and inflammation are common and are associated with myriad ocular conditions ranging from mild disease to blinding conditions. There are numerous anti-invectives with spectra against inciting pathogens. Given the potential for ocular infections to rapidly progress initial broad spectrum therapy is usually required, with therapy tailored as microbiological identification and sensitivities become available. The emergence of antibiotic resistance has become a major health problem. Anti-inflammatory therapy can be institutes to prevent ocular symptoms and end-organ damage...

The reliance of the immune system on constitutive microbial stimulation support the idea that both responsiveness to vaccines and vaccine design need to be considered in the context of host-microbiota interactions. Manipulation of microbe function or composition via diet alteration or microbiota engraftment may soon become a viable approach to control immunity and, as such, vaccine responses. Learning from our endogenous original adjuvants could be critical in overcoming the enormous hurdle of vaccine design against the numerous pathogens that cause chronic infection...

Acute hepatopancreatic necrosis disease (AHPND) is a newly emerging shrimp disease that has severely damaged the global shrimp industry. AHPND is caused by toxic strains of Vibrio parahaemolyticus (V. parahaemolyticus) that have acquired a "selfish plasmid" encoding the deadly binary toxins PirA(vp)/PirB(vp) To better understand the repertoire of virulence factors in AHPND-causing V. parahaemolyticus, we conducted a comparative analysis using genome sequences of the clinical strain RIMD2210633, environmental non-AHPND and toxic AHPND isolates of V...
