The clinical chemical changes induced by Anaplasma marginale infection were determined in 16 adult, intact cows infected with either of 2 virulent isolates and in 8 others treated with a live sheep-attenuated A marginale vaccine and were compared with the clinical chemical analyses in 7 noninfected controls. Blood samples from the cows were analyzed for various serum components and during clinical disease. Cows infected with the 2 virulent isolates had maximum erythrocyte parasitemias (0.5% to 66%) between 1 and 11 days of patency (DP); 7 of the 16 infected animals died within 5 to 12 DP. Cows given the sheep-attenuated anaplasma vaccine had maximum parasitemias (0.1% to 4.2%) between 1 and 16 DP and none died. Infection with the virulent isolates produced severe anemia (mean RBC count = about 2 million/mm3) and caused increases in serum total bilirubin (TBILI), direct bilirubin (DBILI), serum urea nitrogen (SUN), alkaline phosphatase (ALP), and serum aspartate aminotransferase (AST) that were significantly higher than comparable changes in control values. These increases were highest after peak parasitemias in surviving animals. Vaccination with the attenuated isolate produced a mild anemia (mean RBC count = about 5 million/mm3) and a significant increase only in ALP. Marked increase in TBILI, DBILI, SUN, ALP, and AST were detected 0 to 1 day before death in 3 cows. However, such increases were not observed 2 to 4 days before death in the other cows that died.

The clinical and pathological features of 22 patients, 11 males and 11 females 17-70 years of age (48.0 +/- 16.0 years), with hepatic tuberculosis were reviewed. Five patients had no evidence of extrahepatic tuberculosis (local form), and 17 had the miliary form. The clinical features of the miliary and local forms were similar with pyrexia, abdominal pain, hepatomegaly and body weight loss as the main manifestations. The biochemical findings were also quite similar in reversed albumin and globulin (A/G) ratio (2.9/3.5 vs. 3.2/3.4 g/dl) and disproportionate elevation of alkaline phosphatase (ALP) in comparison with bilirubin values but lower levels of alanine aminotransferase (ALT) (40.4 +/- 51.0 vs. 170.8 +/- 209.4 U/l; p < 0.05) and ALP (208.5 +/- 138.9 vs. 389.5 +/- 271.1 U/l; p < 0.05) in the miliary form. Patients with the local form had higher albumin (3.2 +/- 0.8 vs. 2.9 +/- 0.7 g/dl), aspartate aminotransferase (AST) (160.4 +/- 221.7 vs. 65.9 +/- 69.7 U/l), and gamma glutamyl-transpeptidase (gamma GT) (217.0 +/- 144.0 vs. 136.0 +/- 92.1 U/l), although the differences were not significant. The histopathological features of the miliary form were also similar to the local form with granuloma, caseation, acid-fast bacilli, fatty change and portal fibrosis as the main findings. The local form revealed more severe signs of hepatocytic damage while the miliary form was more wasting. The results suggest that the miliary and local forms of hepatic tuberculosis had quite similar clinical presentations and pathological features. The biochemical tests suggesting hepatic tuberculosis were reversed A/G ratio and disproportionate elevation of ALP.

Infection of naive North American horses with 10(4) cell culture infectious doses (CCID50) of virulence variants of African horsesickness virus (AHSV), designated AHSV/4SP, AHSV/9PI, and AHSV/4PI, reproduced three classical forms of African horsesickness: acute (pulmonary), subacute (cardiac), and febrile, respectively. Distinct clinicopathologic and hemostatic abnormalities were associated with each form of disease. Hemostatic abnormalities included increased concentration of fibrin degradation products and prolongation of prothrombin, activated partial thromboplastin, and thrombin clotting times. Hemostatic findings indicated activation of the coagulation and fibrinolytic systems with clotting factor consumption in acute and subacute cases of African horsesickness. Hematologic abnormalities in acute and subacute cases of African horsesickness included leukopenia, decreased platelet counts, elevated hematocrit, and increased erythrocyte counts and hemoglobin concentration. Leukopenia was characterized by lymphopenia, neutropenia, and a left shift. Increased levels of serum creatine kinase, lactate dehydrogenase, aspartate aminotransferase, and alkaline phosphatase, hypocalcemia, hypoalbuminemia, hypoproteinemia, and elevated creatinine, phosphorus, and total bilirubin levels were present in some but not all horses. Metabolic acidosis, indicated by decreased total bicarbonate and increased lactate and anion gap, was present in horses with the acute form of disease. Mild thrombocytopenia and leukopenia were occasionally associated with the febrile form of disease. These results suggest a role for intravascular coagulation in the pathogenesis of African horsesickness.

The role of interdigitating dendritic cells (IDCs) in the early pathogenesis of African swine fever (ASF) was investigated using mandibular lymphoid tissue from normal pigs and pigs inoculated oronasally with highly virulent Lisbon 60 (L-60) and moderately virulent Dominican Republic 1979 (DR-2) ASF virus (ASFV) isolates. Paraffin-embedded tissue sections were immunostained for ASFV antigen and S-100 protein, a marker of IDCs, using an avidin-biotin alkaline phosphatase procedure. Swine IDCs were identified morphologically by light microscopy, electron microscopy, and S-100 immunostaining. Infection with ASFV caused a marked reduction in S-100 staining by 3 days postinfection (DPI) that persisted through 14 DPI. Early ASFV infection of IDCs was demonstrated at 3 DPI by double immunohistochemical staining of cryosections and by transmission electron microscopy. These results support the hypothesis that the failure of a humoral immune response to virulent ASFV may be due to a primary infection of IDCs and the inability of IDCs to initiate an immune response. Infection of IDCs has also been demonstrated with human immunodeficiency virus (HIV-1), and these infections have some aspects in common.

Infection of 60 to 90% of neutrophils with the protozoa, Hepatozoon canis, was detected in 2 dogs. Clinical signs included lethargy, anorexia, and weight loss. Both dogs had severe anemia, leukocytosis, and thrombocytopenia as well as hypoalbuminemia, hyperglobulinemia, and high activities of serum alkaline phosphatase and creatine kinase. Both dogs were treated with imidocarb dipropionate and doxycycline. One dog recovered clinically, with disappearance of parasites from WBC. The other dog died, despite treatment. Necropsy revealed widespread dispersion of schizonts in the parenchymal tissues, but no involvement of skeletal muscle tissues. The disease syndrome that has been identified in the Texas Gulf region is characterized by gait abnormalities associated with multifocal pyogranulomatous myositis, thus, it is distinct clinicopathologically from the syndrome observed in these 2 dogs.

The 1.3 S biotinylatable subunit of Proprionibacterium shermanii transcarboxylase complex was fused to the C-terminus of the human neurokinin 1 receptor gene and introduced into the Semliki Forest virus expression vector pSFV1. RNA transcribed from pSFV1-NK1-biot and pSFV-Helper2 was coelectroporated into BHK cells permitting in vivo packaging of recombinant virus. Infection of BHK and CHO cells with SFV-NK1-biot virus yielded high level of the fusion receptor as detected by metabolic labeling, immunoblotting with streptavidin alkaline phosphatase and binding to substance P. Like native receptor, the biotinylated receptor fusion was able to stimulate Ca2+ mobilization in infected CHO cells, indicating functional coupling to guanine-nucleotide-binding proteins.

In situ hybridization (ISH) provides a means for identifying viral genomes in the context of tissue pathology. We have developed a specific and sensitive ISH probe for the detection of cytomegalovirus (CMV) DNA in formalin-fixed, paraffin-embedded tissue sections. Digoxigenin-11-dUTP was incorporated into a 435-base pair fragment of the CMV Major Immediate Early (MIE) gene with use of the polymerase chain reaction (PCR). Hybridized probe was detected by reaction with antidigoxigenin antibody coupled to alkaline phosphatase and chromogenic substrates. This method has detected CMV infection in routine clinical specimens from a variety of tissue types, including colon, kidney, liver, and stomach. Infection in cells with and without characteristic inclusions is revealed with this probe. The background is so low that single infected cells are detected unambiguously. No cross-hybridization was observed with cells infected with other viruses of Herpesviridae. This approach may be useful for producing probes for the detection of other viral genomes in tissue sections.

We report the utility of a possible lymphocyte fraction of alkaline phosphatase (ALP band-10) activity in serum to predict human immunodeficiency virus type 1 (HIV-1) infection in children born to HIV-1-seropositive mothers. The presence of ALP band 10 in serum consistently correlated with HIV-1 infection status as judged by positive HIV-1 culture, two consecutive HIV-1 p24 antigen results greater than 30 pg/mL in serum, and the subsequent confirmation of seroconversion to HIV-1 antibody after clearance of maternal IgG anti-HIV-1 antibody ascertained between 15 to 24 months post partum. Infection with HIV-1 was correctly identified in 31 samples from 18 patients ranging in age between 0.1 to 10 years; the absence of similar infection was noted in 14 samples from nine patients who served as controls and whose serum samples did not exhibit ALP band-10 activity. This ability of serum ALP band-10 activity to predict HIV-1 infection status in children as young as 2 months may be useful as a surrogate marker for early identification of HIV-1 infection in infants born to HIV-1-seropositive women long before the clearance of maternal anti-HIV-1 antibodies can be ascertained.

Infection due to the Mycobacterium avium complex (MAC) is the most common opportunistic disease of bacterial origin among patients with AIDS in the United States. The incidence of disseminated disease due to MAC (DMAC) has risen dramatically in recent years. The risk of developing DMAC increases as the CD4+ lymphocyte count declines to < 100/mm3. Preliminary analyses of several studies suggest that gender, racial or ethnic group, and individual risk factors for human immunodeficiency virus infection do not influence the incidence of DMAC but that prior Pneumocystis carinii pneumonia, the development of severe anemia, or the interruption of antiretroviral therapy may increase risk. Both the respiratory and the gastrointestinal tracts probably serve as portals of entry for MAC. Colonization may potentiate the risk of DMAC but does not always precede dissemination. Patients with AIDS and DMAC have a shorter duration of survival than do those with AIDS but without DMAC. While treatment for DMAC may extend survival, no well-controlled, prospective, randomized clinical trial has documented this point. Most patients with AIDS and DMAC have disseminated multiorgan disease; the most frequently described symptoms include fever, night sweats, weight loss or wasting, diarrhea, and abdominal pain. The most commonly identified laboratory abnormalities are anemia and elevated serum levels of alkaline phosphatase. Localized disease syndromes related to MAC infection occur less often.

Hypophosphatasia is a congenital disease characterized by defective bone mineralization, deficiency of alkaline phosphatase (ALP) activity, increased excretion of the phosphoethanolamine (PEA) in the urine, and premature loss of the deciduous teeth. A male hypophosphatasia patient (aged 15 years 6 months) with premature exfoliation of the deciduous teeth was referred to our hospital because of severe periodontal destruction in the permanent dentition. Blood and urine tests as well as oral and periodontal examinations were performed. Serum antibody titers against 7 periodontopathic bacteria by the enzyme-linked immunosorbent assay (ELISA), monocyte and neutrophil chemotaxis measurements, and cellular immunity tests were also performed. Low levels of ALP in serum and PEA in the urine were found. Monocyte and neutrophil chemotaxis exhibited normal values. Slightly depressed CD2+, CD3+, and CD4+ and slightly elevated activity of NK cells were found. An elevated level of serum antibody to Porphyromonas gingivalis was observed. Oral radiographic examination showed a mirror pattern of alveolar bone loss which is similar to that seen in localized juvenile periodontitis. Periodontal treatment of this patient was carried out for 4 years. The severely affected sites, the lower right and left first molars and the upper right first molar, had to be extracted. However, the other sites were well maintained. The serum IgG level against P. gingivalis was decreased after 4 years of periodontal treatment. Infection with P. gingivalis was suspected to be associated with the destruction of this patient's hypophosphatasia, but other dental abnormalities such as abnormal enamel, dentin, and cementum formation may also have contributed to the periodontal pathology.
