Pemphigus vulgaris (PV) is a potentially fatal autoimmune mucocutaneous blistering disease. Although PV occurs predominantly in adulthood, in the 3rd to 5th decades of life, there have rarely been reports of childhood cases which are often misdiagnosed. It presents as oral blisters that rupture rapidly and progress to painful erosions. Most patients develop cutaneous flaccid blisters that ruptu...

Secondary bacterial infection in humans is one of the pathological conditions requiring clinical attention. In this study, we examined the effect of lipopolysaccharide (LPS) on encephalomyocarditis virus (EMCV) infected mice. All mice inoculated with EMCV at 5 days before LPS challenge died within 24 h. LPS-induced TNF-α mRNA expression was significantly increased in the brain and heart at 5 da...

Necrotizing fasciitis is characterized by a rapidly progressing necrosis of subcutaneous fat and fascia that rarely occurs in head and neck. It can be life threatening in the case of late diagnosis and antibiotic therapy and without surgical intervention. It is caused by group A streptococci or by a synergistic combination of aerobe and anaerobe microorganisms and bacterial synergy is an import...

        Freshwater crayfish (Astacus leptodactylus) is an important economic fisheries resource of Aras reservoir, Iran. The infection of freshwater crayfish by gram negative and gram positive bacteria are common in natural and cultural environments. These bacteria are considered as secondary disease agents or opportunities. This study was conducted to investigate infes...

Influenza A virus infection can predispose to potentially devastating secondary bacterial infections. Invariant natural killer T (iNKT) cells are unconventional, lipid-reactive T lymphocytes that exert potent immunostimulatory functions. Using a mouse model of postinfluenza invasive secondary pneumococcal infection, we sought to establish whether α-galactosylceramide (α-GalCer [a potent iNKT ce...

Bacterial coinfection represents a major cause of morbidity and mortality in epidemics of influenza A virus (IAV). The bacterium Haemophilus influenzae typically colonizes the human upper respiratory tract without causing disease, and yet in individuals infected with IAV, it can cause debilitating or lethal secondary pneumonia. Studies in murine models have detected immune components involved i...

Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as a leading contributor to mortality during recent influenza pandemics. The mechanism for this influenza-induced susceptibility to secondary S. aureus infection is poorly understood. In this study, we show that innate antibacterial immunity was significantly suppressed during the recovery stage of influenza infection, even though M...

The article presents data on the study of viral-bacterial profile in pigs different ages farms Republic Belarus. It has been established that maximum number PRDC pathogens most households is iso-lated at age 60−80 days, bacterial pathology accumulates gradually and, as a rule, secondary infection (with exception IAR).
 viral and depends epizootic situation farm, complete list CRPC (11 out ...

Influenza A virus (IAV) infection represents a global threat causing seasonal outbreaks and pandemics. Additionally, secondary bacterial infections, caused mainly by Streptococcus pneumoniae, are one of the main complications and responsible for the enhanced morbidity and mortality associated with IAV infections. In spite of the significant advances in our knowledge of IAV infections, holistic ...

Two male dogs at the age of 3 and 5 months of Doberman pinscher and German shepherd breeds were referred to the Veterinary Hospital of Ahvaz University with clinical signs of depression, vomiting, haemorrhagic diarrhoea, profound dehydration, fever and anorexia. The affected dogs had not the history of vaccination. Concurrent infection of canine parvovirus and coronavirus was detected in dogs b...
