Genetic resistance of C3H/RV mice to lethal infection with Banzi virus (flavivirus) was severely compromised by immunosuppression with cyclophosphamide, sublethal X-irradiation, or thymus (T-) cell depletion. The mortality rate among immunosuppressed mice was usually 100%, but average survival times were shorter for mice treated with cyclophosphamide or for X-irradiated mice (10 days) than for T-cell-depleted mice (17 days). Mice treated with cyclophosphamide had high titers of virus in brain, lymphoid tissues, pancreas, and serum. Viral antigen was widespread in brain and pancreas, and mice developed nonsuppurative meningoencephalitis and pancreatitis. Yields of virus, spread of viral antigen, and lesions in T-cell-depleted mice were similar but less severe. Mice treated with cyclophosphamide did not have detectable hemagglutination-inhibiting antibody. T-cell-depleted mice developed hemagglutination-inhibiting antibody but were not protected from lethal infection. These results indicate that genetic resistance of C3H/RV mice to Banzi virus requires immunological factors, and that T-cells play a significant role in resistance to infection with Banzi virus.

In the annuals of autopsy records in Japan, edited by the Japanese Society of Pathology and covering 20 years, from 1958 to 1977, 377841 autopsy cases are registered with a short summary of the pathology findings. Of these, 434 cases with idiopathic, interstitial, viral, non-specific (NSM) and giant cell (GCM) myocarditis were found. The incidences of NSM and GCM were 0.11 and 0.007%, respectively. The annual incidence of NSM showed periodic fluctuations with in 5-year intervals and increased remarkably after 1974. Incidence of GCM showed a similar fluctuation but with a one to two year delay of peaks. The male to female ratio was 1.2: 1 and the age distribution had two peaked patterns for both sexes, though these peaks were scattered widely from neonate to elderly patients. The regional distribution of NSM showed a concentration in the middle portion of Honshu and its regional annual incidence had propagation waves from the central area to peripheral areas. The same tendency was observed in GCM cases. Hokkaido was characterized by a low incidence of NSM and no GCM. Complications of myocarditis included pancreatitis, pneumonitis, interstitial nephritis, meningoencephalitis, hepatitis, hepatic cirrhosis and a considerable incidence of malignancies. Antibiotics, antineoplastic agents, steroids and irradiation therapy were the main forms of treatment applied before or after the start of myocarditis.

Serum alpha-amylase isozymes were separated into three major isozymes by thin-layer gel isoelectric focusing and detected by a starch-iodine zymogram procedure. Of the three groups of isozymes, one (S isozyme) corresponded to a salivary specific form, one (P isozyme) to a pancreatic specific form and the third (SP isozyme) to isozymes of similar isoelectric point common to both secretions. The levels of total alpha-amylase and of these three isozymes were estimated in the sera of 54 patients with mumps. Total alpha-amylase and salivary isozyme concentrations were greatly increased in the sera of all patients compared with controls. Pancreatic isozyme concentrations however, were only slightly increased and did not correlate with clinical pancreatitis. Indeed, in patients with mumps associated with pancreatitis, meningoencephalitis or orchitis, levels of total serum amylase, although higher than controls, were lower than levels in patients who presented solely with mumps sialadenitis.

During March 1979 - February 1980, 53 strains of polioviruses types 2 and 3 were isolated from human specimens and from sewage samples, 52.8% of them on secondary monkey kidney cultures, 47.2% on diploid fibroblasts of human embryonic lung. Type 3 grew more often on monkey cell cultures, type 2 on human ones. Both types of poliovirus circulated in children and adult population during the whole year. Polioviruses were isolated from cerebrospinal fluids of 2 patients without any symptom of paralytic poliomyelitis: an intermediate type 3 in the course of a serologically proved tick-borne encephalitis, and a type 2, different in rct-marker from the vaccinal variant, in the course of a serologically proved parotitis with meningoencephalitis and pancreatitis.

Infection of guinea pigs with an attenuated strain of Junin virus (JV) produced 16% mortality between days 17 and 27 postinfection (p.i.). The morphological study showed a marked pancreatitis between days 6 and 23 p.i. and meningoencephalitis between days 17 and 20 p.i. in a large proportion of the animals. These lesions were coincident with the presence of JV antigenic determinants in the pancreatic acinar cells, neurons and blood vessels of the brain. Infectious virus could be isolated from lymph nodes, spleen, bone marrow, lungs, adrenal glands, and brain. The lesions appeared to be reversible, as they were absent in animals studied after day 64 p.i. Meningoencephalitis, present in all animals dying spontaneously, appeared to be the most important cause of death. Our observations indicate that more accurate markers of virulence must be investigated in the search for attenuated strains of JV as potential vaccine candidates for Argentine hemorrhagic fever.

Herpesvirus 6 (HHV-6) is a ubiquitous virus known to cause febrile syndromes and exanthema subitum in children. Less commonly, and particularly in organ transplant recipients, it may result in hepatitis, bone marrow suppression, interstitial pneunonitis, and meningoencephalitis. This report expands the spectrum of clinical disease associated with HHV-6 by documenting viral infection in a 44-year-old heart transplant recipient presenting with gastroduodenitis, pancreatitis, and hepatitis. On histopathologic examination, the gastric, duodenal, and bile ductular epithelium showed a multinucleate giant cell transformation similar to the cytopathic effect caused by the virus in human T-lymphocytes infected in vitro. Electron microscopy showed herpes particles with a thick tegument layer in the duodenum. Polymerase chain reaction amplified HHV-6 variant A sequences from multiple sites. Serology confirmed the presence of an acute HHV-6 infection. Thus, HHV-6 variant A can cause gastroduodenitis and pancreatitis in immunosuppressed individuals. Multinucleate giant cells and enveloped virions with a prominent tegument can be used as morphologic criteria to raise the possibility of HHV-6 infection in human biopsy tissue.

Cytomegalovirus (CMV) is the most important viral agent in kidney transplantation. Clinical manifestations of CMV disease in transplantation include hepatitis, pneumonitis, pancreatitis, kidney allograft dysfunction, colitis, and meningoencephalitis. However, skin involvement is rare. We describe a severely compromised cadaveric-kidney transplant recipient who developed renal failure, colonic ulcers, and a maculopapular rash accompanied by fever and malaise 4 months after transplantation. Only the skin biopsy was diagnostic and consistent with CMV disease. Intravenous ganciclovir administration resulted in clinical improvement of CMV-induced skin lesions; kidney function normalized and the patient became asymptomatic after 14 days of ganciclovir therapy. Nephrologists should consider the diagnosis of CMV disease in the febrile immunosuppressed patient with skin involvement. Skin biopsy must be considered as a useful and safe procedure in patients with a rash to obtain a prompt diagnosis and efficiently treat this immunocompromised population.

The H5N1 type A influenza viruses that emerged in Hong Kong in 1997 are a unique lineage of type A influenza viruses with the capacity to transmit directly from chickens to humans and produce significant disease and mortality in both of these hosts. The objective of this study was to ascertain the susceptibility of emus (Dramaius novaehollandiae), domestic geese (Anser anser domesticus), domestic ducks (Anas platyrhynchos), and pigeons (Columba livia) to intranasal (i.n.) inoculation with the A/chicken/Hong Kong/220/97 (H5N1) highly pathogenic avian influenza virus. No mortality occurred within 10 days postinoculation (DPI) in the four species investigated, and clinical disease, evident as neurologic dysfunction, was observed exclusively in emus and geese. Grossly, pancreatic mottling and splenomegaly were identified in these two species. In addition, the geese had cerebral malacia and thymic and bursal atrophy. Histologically, both the emus and geese developed pancreatitis, meningoencephalitis, and mild myocarditis. Influenza viral antigen was demonstrated in areas with histologic lesions up to 10 DPI in the geese. Virus was reisolated from oropharyngeal and cloacal swabs and from the lung, brain, and kidney of the emus and geese. Moderate splenomegaly was observed grossly in the ducks. Viral infection of the ducks was pneumotropic, as evidenced by mild inflammatory lesions in the respiratory tract and virus reisolation from oropharyngeal swabs and from a lung. Pigeons were resistant to HK/220 infection, lacking gross and histologic lesions, viral antigen, and reisolation of virus. These results imply that emus and geese are susceptible to i.n. inoculation with the HK/220 virus, whereas ducks and pigeons are more resistant. These latter two species probably played a minimal epidemiologic role in the perpetuation of the H5N1 Hong Kong-origin influenza viruses.

The present study reports the clinical, virological and pathological findings observed in a natural outbreak of highly pathogenic avian influenza in farmed commercial ducks. The ducks developed clinical signs, including mild respiratory distress, depression, mild diarrhoea, loss of appetite and increasing mortality (up to 12%). At necropsy, multifocal mottled necrosis was commonly found in the pancreas with splenomegaly, hepatomegaly, and swollen kidneys. Microscopically, there was necrotized pancreatitis and hepatitis, and lymphocytic meningoencephalitis and myocarditis. Influenza viral antigen was demonstrated in areas closely associated with histopathological lesion. Avian influenza virus was isolated from the caecal tonsil, faeces, and kidney of the domestic ducks. The isolated virus was identified as a highly pathogenic H5N1, with a haemagglutinin proteolytic cleavage site deduced amino acid sequence of ... QREKRKKR/GLFGAIAG ... In order to determine the pathogenicity of the isolate, eight 6-week-old specific pathogen free chickens were inoculated intravenously with the virus, and all birds died within 24 h after inoculation. This is the first report of an outbreak of highly pathogenic avian influenza with clinical signs in commercial domestic ducks in South Korea.

Highly pathogenic avian influenza (HPAI) is an extremely infectious, systemic viral disease of birds that produces high mortality and morbidity. HPAI was diagnosed in the three dead magpies (Pica pica sericea) submitted to the National Veterinary Research and Quarantine Service. At necropsy, the prominent lesions were multifocal or coalescing necrosis of the pancreas with enlargement of the livers and spleens. Microscopically, there were severely necrotizing pancreatitis and lymphocytic meningoencephalitis. Influenza viral antigen was also detected in areas closely associated with histologic lesions. Avian influenza virus was isolated from cecal tonsils and feces of the magpies. The isolated virus was identified as a highly pathogenic H5N1, with hemagglutinin proteolytic cleavage site deduced amino acid sequence of QREKRKKR/GLFGAIAG. To determine the pathogenicity of the isolate, eight 6-wk-old specific-pathogen-free chickens were inoculated intravenously with the virus, and all birds died within 24 hr after inoculation. This is the first report of HPAI in magpies.
