Astroviruses are one of the leading causes of pediatric gastroenteritis worldwide and are clinically importantly pathogens in the elderly and immunocompromised populations. Although the use of cell culture systems and small animal models have enhanced our understanding of astrovirus infection and pathogenesis, little is known about the immune response to astrovirus infection. Studies from human...
objective (s): scar formation in injured peripheral nerve bed causes several consequences which impede the process of nerve regeneration. several animal models are used for scar induction in preclinical studies which target prevention and/or suppression of perineural scar. this study evaluates the translational capacity of four of physical injury models to induce scar formation around the sciat...
Periprosthetic joint infections are devastating complications for patients and for our health system. With growing demand for arthroplasty, the incidence of these infections is projected to increase exponentially. This paper is a review of existing animal models to study periprosthetic infection aimed at providing scientists with a succinct presentation of strengths and weaknesses of available ...
Vibrio vulnificus is an opportunistic pathogen of humans that has the capability of causing rare, yet devastating disease. The bacteria are naturally present in estuarine environments and frequently contaminate seafoods. Within days of consuming uncooked, contaminated seafood, predisposed individuals can succumb to sepsis. Additionally, in otherwise healthy people, V. vulnificus causes wound in...
Staphylococcus aureus is one of the most common causes of nosocomial pneumonia contributing to significant morbidity and mortality. Therapeutic options for patients with methicillin-resistant S. aureus (MRSA) infection are limited. In addition, little is known about the S. aureus virulence factors that may influence the presentation and prognosis of severe lower respiratory tract infections. An...
in this research, 6517 records, collected by khojir sheep breeding station (tehran, iran), during 1991 to 2011 were used to estimate genetic parameters of lamb survival in zandi sheep. genetic parameters were estimated using 16 different models of animal model, sire and threshold models using reml procedures. the aic criterion was used to evaluate the models. the effects in the most suitable an...
In August 2000, the US Food and Drug Administration (FDA) approved ciprofloxacin hydrochloride (Cipro; Bayer) for management of postexposure inhalational anthrax. This was the first antimicrobial drug approved by the FDA for use in treating an infection due to a biological agent used intentionally. The terrorist attacks of 2001 involving anthrax underscore the imperative that safe and effective...
The use of animal models has been essential in understanding the pathogenesis of and hosts immune response to tuberculosis, as well as testing potential antimicrobial compounds and vaccines. Experimental animals have also been used to study infections due to non-tuberculous mycobacteria (NTM). Because there are many different species of NTM capable of causing disease and they have varying degre...
Recurrence of Clostridium difficile-associated diarrhea and pseudomembranous colitis occurs in up to 20% of patients after standard therapy. In these patients, subsequent recurrences are even more frequent. Saccharomyces boulardii, a nonpathogenic yeast, was found to be effective in preventing clindamycin cecitis recurrence in an animal model. We performed an open trial of S. boulardii to evalu...
The etiology of sudden infant death syndrome (SIDS) is unknown but thought to be multifactorial. Several animal models have been developed that induce death without pre-existing symptoms and with pathology similar to that seen in SIDS infants; however, the relevance of these animal models to the events leading to SIDS remains elusive, in part because animal models are as varied as the potential...
