Clinical case definitions for Argentine hemorrhagic fever. (1/248)

Argentine hemorrhagic fever (AHF) is a potentially lethal infection in Argentina. The case-fatality ratio is >15%, but treatment reduces the mortality rate to <1%. Diagnosis is based on clinical and laboratory criteria, but no case definition has been validated. A chart review was conducted for patients hospitalized with suspected AHF. Individuals with a fourfold rise in antibody titer were classified as cases. The combination of a platelet count of <100,000/mm3 and a white blood cell (WBC) count of <2,500/mm3 had a sensitivity and specificity of 87% and 88%, respectively, thus suggesting that the use of these criteria in a case definition would be helpful for epidemiological studies of AHF. The combination of a platelet count of <100,000/mm3 and a WBC count of <4,000/mm3 had a sensitivity of 100% and a specificity of 71%; the use of these criteria in a case definition should be helpful for screening patients for therapy with immune plasma in the region where AHF is endemic.  (+info)

Lassa and Mopeia virus replication in human monocytes/macrophages and in endothelial cells: different effects on IL-8 and TNF-alpha gene expression. (2/248)

Cells of the mononuclear and endothelial lineages are targets for viruses which cause hemorrhagic fevers (HF) such as the filoviruses Marburg and Ebola, and the arenaviruses Lassa and Junin. A recent model of Marburg HF pathogenesis proposes that virus directly causes endothelial cell damage and macrophage release of TNF-alpha which increases the permeability of endothelial monolayers [Feldmann et al. , 1996]. We show that Lassa virus replicates in human monocytes/macrophages and endothelial cells without damaging them. Human endothelial cells (HUVEC) are highly susceptible to infection by both Lassa and Mopeia (a non-pathogenic Lassa-related arenavirus). Whereas monocytes must differentiate into macrophages before supporting even low level production of these viruses, the virus yields in the culture medium of infected HUVEC cells reach more than 7 log10 PFU/ml without cellular damage. In contrast to filovirus, Lassa virus replication in monocytes/macrophages fails to stimulate TNF-alpha gene expression and even down-regulates LPS-stimulated TNF-alpha mRNA synthesis. The expression of IL-8, a prototypic proinflammatory CXC chemokine, was also suppressed in Lassa virus infected monocytes/macrophages and HUVEC on both the protein and mRNA levels. This contrasts with Mopeia virus infection of HUVEC in which neither IL-8 mRNA nor protein are reduced. The cumulative down-regulation of TNF-alpha and IL-8 expression could explain the absence of inflammatory and effective immune responses in severe cases of Lassa HF.  (+info)

Fatal illnesses associated with a new world arenavirus--California, 1999-2000. (3/248)

Arenavirus antibody in rodents indigenous to coastal southern California. (4/248)

The purpose of this study was to extend our knowledge on the geographic and natural rodent host ranges of New World arenaviruses in California. Sera from 1,094 sigmodontine and 112 murine rodents were tested for antibody against Whitewater Arroyo and Amapari viruses. Antibody was found in 55 (4.6%) of the 1,206 rodents: 4 from northwestern San Diego County, 3 from Los Angeles County, and 48 from Orange County. The antibody-positive rodents included 8 (7.8%) of 103 Neotoma fuscipes, 1 (0.6%) of 180 Neotoma lepida, 1 (3.1%) of 32 Peromyscus boylii, 8 (11.0%) of 73 Peromyscus californicus, 1 (1.2%) of 85 Peromyscus eremicus, 30 (8.5%) of 353 Peromyscus maniculatus, and 6 (2.2%) of 268 Reithrodontomys megalotis. This study provides the first evidence that New World arenaviruses occur in Los Angeles and Orange counties and northwestern San Diego County, and the first evidence that Peromyscus and Reithrodontomys species are naturally infected with New World arenaviruses.  (+info)

Experimental infection of Neotoma albigula (Muridae) with Whitewater Arroyo virus (Arenaviridae). (5/248)

The Whitewater Arroyo virus (WWA) is a newly described North American arenavirus. The purpose of this study was to elucidate the biology of this virus in its natural rodent host, Neotoma albigula (white-throated woodrat). Thirteen adult, 7 juvenile, and 8 newborn woodrats each were inoculated subcutaneously with 1,000 cell culture infectious dose50 of the WWA virus prototype strain AV 9310135. All 28 animals became infected (as measured by the recovery of infectious virus and/or seroconversion) and no overt illness was associated with infection. Infection and virus shedding in the adult animals were transient (less than 59 days) whereas virus shedding in animals inoculated at birth persisted through 164 days of age. These results indicate that the duration of WWA virus infection in N. albigula is dependent upon the animal's age at the onset of infection and that neonatal infection can result in chronic (perhaps lifelong) virus shedding.  (+info)

Distinct CD8 T cell functions mediate susceptibility to histoplasmosis during chronic viral infection. (6/248)

It has long been recognized that some viral infections result in generalized immune suppression. In acute infections, this period of suppressed immunity is relatively short. However, chronic infections associated with a prolonged period of immune suppression present far greater risks. Here, we examined the role of CD8 T cell responses following viral infection in immunity to systemic histoplasmosis. Although wild-type mice with systemic histoplasmosis were able to control the infection, those simultaneously infected with lymphocytic choriomeningitis virus clone 13 showed reduced immunity with greater fungal burden and high mortality. The immune suppression was associated with loss of CD4 T cells and B cells, generalized splenic atrophy, and inability to mount a granulomatous response. Removing the anti-viral CD8 T cells in the coinfected mice enabled them to reduce the fungal burden and survive the infection. Their lymphoid organs were replenished with CD4 T and B cells. In contrast to wild-type mice, perforin-deficient mice infected with lymphocytic choriomeningitis virus clone 13 and Histoplasma showed an absence of immunopathology, but the animals still died. These results show that CD8 T cells can suppress immunity through different mechanisms; although immunopathology is perforin-dependent, lethality is perforin-independent.  (+info)

Molecular analysis of the interaction of LCMV with its cellular receptor [alpha]-dystroglycan. (7/248)

alpha-Dystroglycan (DG) has been identified as the cellular receptor for lymphocytic choriomeningitis virus (LCMV) and Lassa fever virus (LFV). This subunit of DG is a highly versatile cell surface molecule that provides a molecular link between the extracellular matrix (ECM) and a beta-DG transmembrane component, which interacts with the actin-based cytoskeleton. In addition, DG exhibits a complex pattern of interaction with a wide variety of ECM and cellular proteins. In the present study, we characterized the binding of LCMV to alpha-DG and addressed the role of alpha-DG-associated host-derived proteins in virus infection. We found that the COOH-terminal region of alpha-DG's first globular domain and the NH2-terminal region of the mucin-related structures of alpha-DG together form the binding site for LCMV. The virus-alpha-DG binding unlike ECM alpha-DG interactions was not dependent on divalent cations. Despite such differences in binding, LCMV and laminin-1 use, in part, an overlapping binding site on alpha-DG, and the ability of an LCMV isolate to compete with laminin-1 for receptor binding is determined by its binding affinity to alpha-DG. This competition of the virus with ECM molecules for receptor binding likely explains the recently found correlation between the affinity of LCMV binding to alpha-DG, tissue tropism, and pathological potential. LCMV strains and variants with high binding affinity to alpha-DG but not low affinity binders are able to infect CD11c+ dendritic cells, which express alpha-DG at their surface. Infection followed by dysfunction of these antigen-presenting cells contributes to immunosuppression and persistent viral infection in vivo.  (+info)

Role of CD28-B7 interactions in generation and maintenance of CD8 T cell memory. (8/248)

Although the role of CD28-B7 interaction in the activation of naive T cells is well established, its importance in the generation and maintenance of T cell memory is not well understood. In this study, we examined the requirement for CD28-B7 interactions in primary T cell activation and immune memory. Ag-specific CD8 T cell responses were compared between wild-type (+/+) and CD28-deficient (CD28(-/-)) mice following an acute infection with lymphocytic choriomeningitis virus (LCMV). During the primary response, there was a substantial activation and expansion of LCMV-specific CD8 T cells in both +/+ and CD28(-/-) mice. However, the magnitude of the primary CD8 T cell response to both dominant and subdominant LCMV CTL epitopes was approximately 2- to 3-fold lower in CD28(-/-) mice compared with +/+ mice; the lack of CD28-mediated costimulation did not lead to preferential suppression of CD8 T cell responses to the weaker subdominant epitopes. As seen in CD28(-/-) mice, blockade of B7-mediated costimulation by CTLA4-Ig treatment of +/+ mice also resulted in a 2-fold reduction in the anti-LCMV CD8 T cell responses. Loss of CD28/B7 interactions did not significantly affect the generation and maintenance of CD8 T cell memory; the magnitude of CD8 T cell memory was approximately 2-fold lower in CD28(-/-) mice as compared with +/+ mice. Further, in CD28(-/-) mice, LCMV-specific memory CD8 T cells showed normal homeostatic proliferation in vivo and also conferred protective immunity. Therefore, CD28 signaling is not necessary for the proliferative renewal and maintenance of memory CD8 T cells.  (+info)

Looking for online definition of Arenaviridae infections in the Medical Dictionary? Arenaviridae infections explanation free. What is Arenaviridae infections? Meaning of Arenaviridae infections medical term. What does Arenaviridae infections mean?
Arenaviruses are enveloped, bipartite negative single-stranded RNA viruses that can cause a wide spectrum of disease in humans and experimental animals including hemorrhagic fever. The majority of these viruses are rodent-borne and the arenavirus family can be divided into two groups: the Lassa-Lymphocytic choriomeningitis serocomplex and the Tacaribe serocomplex. Arenavirus-induced disease may include characteristic symptoms ranging from fever, malaise, body aches, petechiae, dehydration, hemorrhage, organ failure, shock, and in severe cases death. Currently, there are few prophylactic and therapeutic treatments available for arenavirus-induced symptoms. Supportive care and ribavirin remain the predominant strategies for treating most of the arenavirus-induced diseases. Therefore, efficacy testing of novel therapeutic and prophylactic strategies in relevant animal models is necessary. Because of the potential for person-to-person spread, the ability to cause lethal or debilitating disease in humans,
Persistent viral infections can interfere with FcγR-mediated antibody effector functions by excessive immune complex (IC) formation, resulting in resistance to therapeutic FcγR-dependent antibodies. We and others have previously demonstrated that mice persistently infected with lymphocytic choriomeningitis virus (LCMV) are resistant to a wide range of depleting antibodies due to excessive IC formation. Here, we dissect the mechanisms by which two depleting antibodies overcome the obstacle of endogenous ICs and achieve efficient target cell depletion in persistently infected mice. Efficient antibody-mediated depletion during persistent LCMV infection required increased levels of antibody bound to target cells or use of afucosylated antibodies with increased affinity for FcγRs. Antibodies targeting the highly expressed CD90 antigen or overexpressed human CD20 efficiently depleted their target cells in naïve and persistently infected mice, whereas antibodies directed against less abundant ...
Lymphocytic Choriomeningitis (LCM) Lymphocytic choriomeningitis, or LCM, is a rodent-borne viral infectious disease caused by lymphocytic choriomeningitis virus (LCMV), a member of the family Arenaviridae that was initially isolated in 1933. The primary host of LCMV is the common house mouse, Mus musculus. Infection in house mouse populations may vary by geographic location, though it is estimated that 5% of house mice throughout the United States carry LCMV and are able to transmit virus for the duration of their lives without showing any sign of illness. Other types of rodents, such as hamsters, are not the natural reservoirs but can become infected with LCMV from wild mice at the breeder, in the pet store, or home environment. Humans are more likely to contract LCMV from house mice, but infections from pet rodents have also been reported.. LCMV infections have been reported in Europe, the Americas, Australia, and Japan, and may occur wherever infected rodent hosts of the virus are found. The ...

A small mouse stock in which lymphocytic choriomeningitis is endemic has been observed over a period of 4 years. The disease has persisted during that time, but it has become so mild that it can no longer be recognized by clinical observation. In spite of this fact, all of the stock mice tested, both young and old, carried considerable amounts of virus in their organs and blood. The females readily transmit the infection to their offspring. Intrauterine infection has become the only mode of transmission of the disease in contrast to the situation in 1935 when a certain number of mice were born virus-free and became infected by contact shortly after birth.. The present mildness of the disease appears to be due to two factors, namely, the change in its mode of transmission just mentioned, and a shift in the severity of the disease with regard to the age of the host at the time of infection. This shift has occurred gradually since 1935 when the mice infected in utero were the only ones to become ...

Several viruses in the Arenaviridae family infect humans and cause severe hemorrhagic fevers which lead to high case fatality rates. Due to their pathogenicity and geographic tropisms, these viruses remain very understudied. As a result, an effective vaccine or therapy is urgently needed. Here, we describe efforts to produce cross-reactive monoclonal antibodies that bind to both New and Old World arenaviruses. All of our MAbs seem to be nonneutralizing and nonprotective and target subunit 2 of the glycoprotein. Due to the lack of reagents such as recombinant glycoproteins and antibodies for rapid detection assays, our MAbs could be beneficial as analytic and diagnostic tools.

Michael B.A. Oldstone is a Professor in the Department of Immunology & Microbial Science at The Scripps Research Institute where he heads the Viral-Immunobiology Laboratory. He focuses on viral-host interactions, especially how viruses cause disease. His work studying the prototype arenavirus lymphocytic choriomeningitis virus dissected the biologic and molecular parameters of how virus infection leads to the submission or the enhancement of the immune response. Submission or subversion leads to viral persistence and enhancement to autoimmunity and immunopathology. Using experimental animal model systems, his findings, especially with virus-specific cytotoxic T cells, with molecules that negatively regulate such cytotoxic T cells and with formation and consequences of viral antibody immune complexes, have been extended to infectious diseases of humans. These paradigm observations, coupled with his work on viral variants and dendritic cell interactions have led to his election to the National ...
Isolates of lymphocytic choriomeningitis virus (LCMV) that elicit a cytotoxic T-lymphocyte response (CTL+) have been compared with isolates that suppress the CTL response (CTL-) in an effort to map this phenotype. A single amino acid change in the glycoprotein of the LCMV Armstrong (ARM) strain is consistently associated with the CTL- trait and the ability of the virus to persist (P+). The CTL+ P- parental strain spontaneously gives rise to CTL- P+ variants within lymphoid tissues of mice persistently infected from birth. To map the structural basis of the phenotype, the complete RNA sequence of LCMV ARM 53b (CTL+) was compared with that of its variant ARM clone 13 (CTL-). Differences in 5 of 10,600 nucleotides were found. Three changes are noted in the large L RNA segment, and two are noted in the small S RNA segment. Only two of the changes distinguishing CTL+ from CTL- isolates affect amino acid coding: lysine to glutamine at amino acid 1079 of the polymerase protein, and phenylalanine to ...
Persistent infection of C3H/St mice with certain strains of lymphocytic choriomeningitis virus (LCMV) causes a growth hormone (GH) deficiency syndrome (GHDS) manifested as growth retardation and hypoglycemia. Infected mice show high levels of viral replication in the GH-producing cells in the anterior pituitary leading to decreased synthesis of GH mRNA and protein despite the absence of detectable virus-induced cell structural damage. Virus clones isolated from the GHDS-negative LCMV WE strain can cause the disease, while others cannot. The genetic basis of this phenotypic difference is a nucleotide substitution resulting in a single amino acid difference in the viral glycoprotein. Reassortant studies indicate that the single amino acid substitution (Ser-153 to Phe) is sufficient to allow infection of the GH-producing cells and cause GHDS. These results show that a single change in the genome can affect viral pathogenicity by altering the tropism of the virus.
THE interaction of lymphocytic choriomeningitis (LCM) virus with mouse tissues has been discussed recently1-5. The fulminating disease, which occurs in adult mice after intracerebral inoculation with LCM virus, can be ameliorated by several treatments known to impair the immune response of the host, such as X-rays6, amethopterin7, thymectomy8 and anti-lymphocyte serum9. The pathology of the disease10 supports the current view that an immune reaction by the host against the virus or a virus product, located in or on infected cells, plays an essential part in its pathogenesis. A similar mechanism may be important in the chronic autoimmune-like disease in virus carrier mice2,5. Further elucidation of this disease mechanism depends on understanding the nature of the immune response and its target. A question of considerable interest is what the consequences might be for virus infected cells in the event of an immune response against the virus or a virus product. Here we report preliminary experiments

Lymphocytic choriomeningitis (LCM) is a rodent-borne viral infectious disease that presents as aseptic meningitis, encephalitis or meningoencephalitis. Its causative agent is the lymphocytic choriomeningitis virus (LCMV), a member of the family Arenaviridae. The name was coined by Charles Armstrong in 1934. The Gale Encyclopedia of Medicine defines lymphocytic choriomeningitis (LCM) as "a viral infection of the membranes surrounding the brain and spinal cord and of the cerebrospinal fluid". The name is based on the tendency of an individual to have abnormally high levels of lymphocytes during infection. Choriomeningitis is "cerebral meningitis in which there is marked cellular infiltration of the meninges, often with a lymphocytic infiltration of the choroid plexuses". There are several strains of LCM virus, among which the most widely used are LCMV Armstrong and LCMV Clone 13. Armstrong is the original virus strain which was isolated from the brain by Charles Armstrong in 1934. It triggers a ...

Los síndromes infecciosos asociados a arenavirus en América del sur son cuatro: síndrome febril de origen viral; fiebres hemorrágicas con o sin compromiso neurológico; meningitis asépticas y meningo-encefalitis. Entre los Arenavirus del nuevo mundo, está el complejo Tacaribe donde se encuentran los virus: Junín (Argentina), Guanarito (Venezuela), Machupo (Bolivia) y Sabiá (Brasil), que se caracterizan por causar fiebres hemorrágicas. En Colombia fue aislado el arenavirus Pichindé en 1965, del roedor Oryzomys albigularis, en el valle de Pichindé (Valle del Cauca). Este arenavirus produce una infección persistente en su hospedero y no es patógeno para el hombre. Hay evidencias de la circulación del virus Guanarito en roedores de Córdoba, pero no existen casos diagnosticados en humanos; en Sincelejo (Colombia) se detectó el genoma del virus coriomeningitis linfocítica en cerebros de roedores Mus musculus. El diagnóstico se basa en el conocimiento de la epidemiología local y la sospecha

Three patients who received visceral-organ transplants from a single donor on the same day died of a febrile illness 4 to 6 weeks after transplantation. Culture, polymerase-chain-reaction (PCR) and serologic assays, and oligonucleotide microarray analysis for a wide range of infectious agents were not informative.,We evaluated RNA obtained from the liver and kidney transplant recipients. Unbiased high-throughput sequencing was used to identify microbial sequences not found by means of other methods. The specificity of sequences for a new candidate pathogen was confirmed by means of culture and by means of PCR, immunohistochemical, and serologic analyses.,High-throughput sequencing yielded 103,632 sequences, of which 14 represented an Old World arenavirus. Additional sequence analysis showed that this new arenavirus was related to lymphocytic choriomeningitis viruses. Specific PCR assays based on a unique sequence confirmed the presence of the virus in the kidneys, liver, blood, and cerebrospinal ...
Viral hemorrhagic fevers (VHFs) caused by arenaviruses are acute diseases characterized by fever, headache, general malaise, impaired cellular immunity, eventual neurologic involvement, and hemostatic alterations that may ultimately lead to shock and death. The causes of the bleeding are still poorly understood. However, it is generally accepted that these causes are associated to some degree with impaired hemostasis, endothelial cell dysfunction and low platelet counts or function. In this article, we present the current knowledge about the hematological alterations present in VHF induced by arenaviruses, including new aspects on the underlying pathogenic mechanisms.

N2 - Previous studies have identified the inhibitory role that the programmed death 1 (PD-1) pathway plays during chronic infection. Blockade of this pathway results in rescue of viral-specific CD8 T cells, as well as reduction of viral loads in mice chronically infected with lymphocytic choriomeningitis virus (LCMV). We tested the effect of combining PD ligand 1 (PD-L1) blockade with an agonistic regimen that induces 4-1BB costimulation during chronic LCMV infection. There is a boosting effect in the rescue of LCMV-specific CD8 T cell responses after dual treatment with PD-L1 blockade and 4-1BB agonistic Abs when the amount and timing ...

A Ohio woman who went whitewater rafting in North Carolina has died of an infection after being exposed to an amoeba that is naturally present in warm, fresh water.
In a mouse colony in which lymphocytic choriomeningitis is endemic infection takes place either in utero or shortly after birth. Virus is discharged from infected mice with the nasal secretions and urine. In some mice the infection lasts for several months, and such carriers can transmit the disease to healthy mice by contact. The portal of entry appears to be the nasal mucosa rather than the gastrointestinal tract. Mice infected by contact show no definite symptoms while those infected in utero often do. The disease has persisted in the colony for at least 15 months without change in its character. Mouse stocks differ in their susceptibility to contact infection and the findings given in the paper could be reproduced only with a very susceptible stock. Wild mice (Mus musculus) can be infected by contact, although less easily than our white mice.. The source of the infection in the colony has not been determined. The fact that the serum of the caretaker neutralizes the virus indicates that he ...

In ICF whitewater slalom paddlers negotiate their way down a 300 m (980 ft) of whitewater rapids, through a series of up to 25 gates (pairs of hanging poles.) The colour of the poles indicates the direction in which the paddlers must pass through; time penalties are assessed for striking poles or missing gates. Categories are C1 (solo) and C2 (tandem), the latter for two men, and C2M (mixed) for one woman and one man.[39] C1 boats must have a minimum weight and width of 10 kg (22 lb) and 0.65 m (2 ft 2 in) and be not more than 3.5 m (11 ft) long. C2s must have a minimum weight and width of 15 kg (33 lb) and 0.75 m (2 ft 6 in), and be not more that 4.1 m (13 ft). Rudders are prohibited. Canoes are decked and propelled by single-bladed paddles, and the competitor must kneel.[40].

Pichinde virus (PIC) is a reticuloendothelial arenavirus of the New World tropics. A guinea pig passage-adapted strain of this virus (adPIC) is uniformly lethal for inbred guinea pigs, while the related, prototype strain (PIC3739) has attenuated virulence. The abilities of adPIC and PIC3739 to induce tumor necrosis factor (TNF) in vivo and in cultured macrophages were compared. Infection with adPIC, but not PIC3739, was associated with detectable serum TNF that peaked in week 2 of infection. Tumor necrosis factor was found in the spleens of adPIC- and PIC3739-infected animals in week 1 of infection ; TNFα mRNA levels in spleens and livers of adPIC infected animals increased and remained high throughout infection, whereas PIC3739-infected organs showed down regulation of TNFα mRNA late in infection. Peritoneal macrophages explanted from adPIC-infected animals showed enhanced lipopolysaccharide-inducible TNF production. Altered regulation of TNF production may play a role in the pathogenesis of guinea

TY - JOUR. T1 - Effect of Chronic Viral Infection on Epitope Selection, Cytokine Production, and Surface Phenotype of CD8 T Cells and the Role of IFN-γ Receptor in Immune Regulation. AU - Tewari, Kavita. AU - Sacha, Jonah. AU - Gao, Xiaoyan. AU - Suresh, M.. PY - 2004/2/1. Y1 - 2004/2/1. N2 - Regulation of CD8 T cell responses in chronic viral infections is not well understood. In this study, we have compared the CD8 T cell responses to immunodominant and subdominant epitopes during an acute and a chronic lymphocytic choriomeningitis virus (LCMV) infection in mice. The epitope hierarchy of the primary CD8 T cell response was similar in acute and chronic LCMV infections. However, strikingly, the epitope hierarchy of the primary CD8 T cell response was conserved in the T cell memory only in an acute but not in a chronic LCMV infection. Interestingly, in an acute infection, increasing the viral dose caused significant changes in the epitope hierarchy of the LCMV-specific memory CD8 T cell pool, ...

Classical microparasite evolution theory predicts a trade-off between virulence and transmission [1-3]. This trade-off balances virulence and within-host reproduction so that transmission is maximized over the lifetime of infection. Microparasites expressing intermediate levels of virulence are favoured under those conditions, as seen in several empirical examples of viruses with high transmission success (e.g. infections of myxoma virus in rabbits, HIV in humans, and cauliflower mosaic virus in Brassica rapa) [4-6]. However, not all studies found evidence for evolution towards intermediate virulence, but instead suggested evolution towards high or low virulence [7, 8].. Host population density is a key factor in determining whether low or high virulence will be optimal [9-11]. This mechanism can be understood in the framework of a trade-off between a microparasites competitive ability and its persistence. When transmission rates are lower at low host densities, a strain that can maintain a ...
Three clusters of organ transplant-associated lymphocytic choriomeningitis virus (LCMV) transmissions have been identified in the United States; 9 of 10 recipients died. In February 2011, we identified a fourth cluster of organ transplant-associated LCMV infections. Diabetic ketoacidosis developed in the organ donor in December 2010; she died with generalized brain edema after a short hospitalization. Both kidneys, liver, and lung were transplanted to 4 recipients; in all 4, severe posttransplant illness developed; 2 recipients died. Through multiple diagnostic methods, we identified LCMV infection in all persons, including in at least 1 sample from the donor and 4 recipients by reverse transcription PCR, and sequences of a 396-bp fragment of the large segment of the virus from all 5 persons were identical. In this cluster, all recipients developed severe illness, but 2 survived. LCMV infection should be considered as a possible cause of severe posttransplant illness ...
Boid inclusion body disease (BIBD) is a viral disease of boid snakes believed to be caused by reptarenavirus belonging to the family Arenaviridae. Unlike most mammalian arenaviruses, the reservoir host for reptarenavirus is still unknown. In this study, the pathological responses were evaluated in a mouse model for a period of 28 days. Blood and tissue samples (lung, liver, spleen, heart, kidney and brain) were collected for evaluation of hematology, biochemistry, histopathology and oxidative enzyme levels at six time points (1, 3, 7, 14, 21 and 28 days), after viral infection (2 ...

BACKGROUND INFORMATION ABOUT CONVALESCENT PLASMA: Passive immunity has proven effective for cytomegalovirus (CMV), hepatitis B virus, rabies, tetanus, varicella, certain SARS variants, Argentine Hemorrhagic Fever, and various other illnesses. Convalescent plasma has been cited as a potential therapy for viral infection dating back to the 1918 Spanish influenza A (H1N1) pandemic. Since that time, convalescent plasma as passive immune therapy has been evaluated in the treatment of: Ebola, SARS coronavirus (SARS-CoV), 2009 pandemic influenza A (H1N1), Argentine Hemorrhagic Fever, CMV, Parvovirus B19, and others. Furthermore, a February 2020 WHO report states "The cellular infectivity of the isolated viruses could be completely neutralized by the sera collected from convalescent patients."

We use simple mathematical models to examine the dynamics of primary and secondary cytotoxic T-lymphocyte (CTL) responses to viral infections. In particular, we are interested in conditions required to resolve the infection and to protect the host upon secondary challenge. While protection against reinfection is only effective in a restricted set of circumstances, we find that resolution of the primary infection requires persistence of CTL precursors (CTLp), as well as a fast rate of activation of the CTLp. Since these are commonly the defining characteristics of CTL memory, we propose that CTL memory may have evolved in order to clear the virus during primary challenge. W e show experimental data from lymphocytic choriomeningitis virus infection in mice, supporting our theory on CTL memory. We adapt our models to HIV and find that immune impairment during the primary phase of the infection may result in the failure to establish CTL memory which in turn leads to viral persistence. Based on our ...
