The highly pathogenic avian influenza (HPAI) H5N1 viruses continue to cause major problems in poultry and can, although rarely, cause human infection. Being enzootic in domestic poultry, Egyptian isolates are continuously evolving, and novel clades vary in their pathogenicity in avian hosts. Considering the importance of domestic ducks as natural hosts of HPAI H5N1 viruses and their likelihood of physical contact with other avian hosts and humans, it is of utmost importance to characterize the pathogenicity of newly emerged HPAI strains in the domestic duck...

BACKGROUND: Enterovirus (EV) infection has been a serious health issue in Asia-Pacific region. It has been indicated that the occurrence of fatal hand foot and mouth disease (HFMD) cases following EV71 infection is mainly attributed to pulmonary edema. However, the development of pulmonary disorders after EV71 infection remains largely unknown. To establish an EV71-infected animal model and further explore the underlying association of central nervous system (CNS) invasion with pulmonary edema, we isolated a clinical source EV71 strain (ZZ1350) from a severe case in Henan Province...

BACKGROUND: As the quest to eradicate malaria continues, there remains a need to gain further understanding of the disease, particularly with regard to pathogenesis. This is facilitated, apart from in vitro and clinical studies, mainly via in vivo mouse model studies. However, there are few studies that have used gerbils (Meriones unguiculatus) as animal models. Thus, this study is aimed at characterizing the effects of Plasmodium berghei ANKA (PbA) infection in gerbils, as well as the underlying pathogenesis...

Cysticercosis is a systemic parasitic infestation caused by ingesting the eggs of the pork tapeworm, Taenia solium. The central nervous system (CNS) is the most important primary site of infection and disease can present with solitary or multiple space-occupying lesion. Other organs like subcutaneous tissues, muscles, heart, liver, lungs, and peritoneum are more frequently affected but maxillofacial region involvement is rare. The diagnosis of cysticercose is evoked on US examination and CT scan, but confirmation is only possible by Fine needle aspiration cytology [FNAC] or histological examination in case of surgical removal of the oral lesion which can identify the Taenia solium larva...

Neurologic complications are common after hematopoietic stem cell transplantation (HSCT) and solid organ transplantation (SOT) and affect 30-60% of transplant recipients. The aim of this article is to provide a practical imaging approach based on the timeline and etiology of CNS abnormalities, and neurologic complications related to transplantation of specific organs. The lesions will be classified based upon the interval from HSCT procedure: pre-engraftment period <30 days, early post-engraftment period 30-100 days, late post-engraftment period >100 days, and the interval from SOT procedure: postoperative phase 1-4 weeks, early posttransplant syndromes 1-6 months, late posttransplant syndromes >6 months...

BACKGROUND: Health-care-associated infections characterised by antibiotic drug resistance are a global medical challenge that claims billions of dollars of health-care expenditure. Bacterial adhesion and subsequent formation of biofilms on catheters and tubes are the primary mechanisms through which these infections are initiated and propagated. We tested the efficacy and safety for clinical treatment of a coating based on natural protein, in which immunogenicity was eliminated through physical plasticising, applied to the surfaces of medical devices to inhibit bacterial adhesion...

Recent Zika virus (ZIKV) outbreaks have been associated with an increased incidence of neonatal microcephaly. Subsequently, tropism for the brain was established in human fetal brain tissue. We present the first congenital ZIKV infection in the United States, confirmed by high ZIKV immunoglobulin M antibody titers in serum and cerebrospinal fluid. The phenotypic characteristics of the patient fall within fetal brain disruption sequence, suggesting impaired brain development in the second half of gestation. Brain imaging revealed an almost agyric brain with diffuse parenchymal calcifications, hydrocephalus ex vacuo, and cerebellar hypoplasia...

Toxocarosis is an important parasitic zoonosis which is mainly caused by the infective larvae of Toxocara canis. To identify whether there are correlations among the infectious dose, the larval migrans and immune modulation in inbred Chinese Kun Ming (KM) mice, experimental infections were carried out with a range of dosages of 100, 500, 1000, 2000, and 3000 embryonated eggs (EE). Pathogenic reactions were observed in terms of physical and central nervous symptoms. Distributions of T. canis larvae in liver, lung, kidney, heart and brain organs were respectively detected by scanning tissue sections...

Four doves (Nos. 1-4 birds) affected with neurological signs (ataxia, circling and torticollis) were investigated pathologically and microbiologically. Viral isolation was tried from the tracheal and cloacal swabs of all 4 birds and from liver, spleen, kidney, heart, lung and brain of Nos. 1 and 2 birds. No viruses were isolated from 4 birds, but they had high serum antibody titers against avian paramyxovirus 1 (APMV-1). Histologically, they had the characteristic histological changes of pigeon APMV-1 infection; nonpurulent encephalitis and interstitial nephritis...

Acute ruminal acidosis is a metabolic status defined by decreased blood pH and bicarbonate, caused by overproduction of ruminal D-lactate. It will appear when animals ingest excessive amount of nonstructural carbohydrates with low neutral detergent fiber. Animals will show ruminal hypotony/atony with hydrorumen and a typical parakeratosis-rumenitis liver abscess complex, associated with a plethora of systemic manifestations such as diarrhea and dehydration, liver abscesses, infections of the lung, the heart, and/or the kidney, and laminitis, as well as neurologic symptoms due to both cerebrocortical necrosis and the direct effect of D-lactate on neurons...

The present study evaluated the pathogenicity of Baylisascaris potosis, a newly described ascarid nematode, in Mongolian gerbils. Gerbils were infected with varying doses of either B. potosis or Baylisascaris transfuga embryonated eggs (100, 1,000, and 4,000) for 30 days postinfection (pi). Baylisascaris potosis-infected gerbils showed no clinical signs of disease; however, gerbils exposed to 1,000 and 4,000 B. transfuga eggs showed severe neurologic signs at 22-29 days and 14-15 days pi, respectively. Histopathologic examination revealed larvae and lesions in the intestine, lung, liver, and muscles of B...

A reliable disease model mimicking Enterovirus 71 (EV71) infection in humans is essential for understanding pathogenesis and for developing a safe and effective vaccine. Commonly used rodent models including mouse or rat models are not suitable for vaccine evaluation because the rodents are resistant to EV71 infection after they reach the age of 6 days. In this study, 21-day-old gerbils inoculated intraperitoneally (IP) with a non mouse-adapted EV71 strain developed neurological lesion-related signs including hind limb paralysis, slowness, ataxia and lethargy similar to those of central nervous system (CNS) infection of EV71 in humans...

Since April 2010, a novel contagious disease in ducks and geese, with egg drop, feed uptake decline and neurological signs, caused by a newly emerged virus has spread around Eastern China. Dissection conducted on the dead geese demonstrated hemorrhage in brain, lung, liver, heart, ovary, and enlarged and necrotic spleen. A new virus, named Goose/Jiangsu/804/2010 (JS804) virus, was isolated in Jiangsu area from geese. Then the virus was re-isolated from the affected geese and replicated well in duck embryo fibroblasts and Vero cells, causing the cytopathic effect...

Cytomegalovirus (CMV) is the most prevalent infectious agent causing neurological dysfunction in the developing brain. This study analysed the different patterns of tissue damage, particularly in the brain, of fetuses with documented CMV infection. We studied 45 fetuses at 20-21 weeks of gestation with congenital CMV infection documented by invasive positive prenatal diagnosis. At the time of amniocentesis, abnormal ultrasound findings had been recorded for 13 of the 45 fetuses (29%). Histological and immunohistochemical characterization was performed on the placenta, brain, heart, lung, liver, kidney, and pancreas...

The pathogenesis and kinetics of oral infection by equine herpesvirus (EHV)-9 were studied in mice and hamsters. After oral inoculation of 10(5) plaque-forming units (PFU) of virus, 1-week-old suckling hamsters showed varying severity of neurological disease from 72 hours post inoculation (hpi) and all of these animals had died by 96 hpi. Four-week-old ICR mice inoculated orally with 4 × 10(4)PFU of virus showed no clinical signs, but they developed erosive and ulcerative gastritis from 36 hpi. Varying degrees of encephalitis were seen in infected mice and hamsters, and the hamsters also developed myelitis by 96 hpi...
