Using the fluorescent antibody test, the presence of antibody-coated bacteria in 10 out of 17 urine sediment samples from cattle infected with Corynebacterium renale is described. These antibodies were mainly of the immunoglobulin class IgG, and to a lesser extent IgA. This finding is characteristic for infections of the upper urinary tract (pyelonephritis). In seven samples no antibody coating of the bacterial surface was detected. In these cases an infection of the lower urinary tract (cystitis) is suggested.

Three female and three male unsuckled newborn Holstein calves were tube-fed pooled colostrum and fresh colostrum respectively at a mean dose of 81.1 ml per kg birth weight at about six hours of age. The pre-colostral mean total serum immunoglobulin gradually increased from 0.07 mg per ml to 31.73 mg per ml by one day of age. IgG1, IgG2, IgG and IgM gradually increased to maximum concentrations by one day of age. IgA was higher in the 14 hour than in the 24 hour sample due to catabolic loss. The pre-colostral packed cell volume (PCV) of 41.83 per cent significantly (P less than 0.05) decreased to 37.17 per cent 18 hours after intubation. The pre-ruminant rumen of the newborn calf can empty itself efficiently and adequate intestinal absorption of colostral proteins can take place before closure sets in. Normogammaglobulinaemia can be established in almost all normal calves and neonatal morbidity and mortality reduced by force-feeding newborn calves with good quality colostrum immediately after birth.

The influence of serum immunoglobulins on the incidence of calf pneumonia, and the relationship between sub-clinical pneumonia, and calf serum Ig levels, is discussed. Monospecific antisera were used to measure levels of IgG1, IgG2, IgM and IgA in the sera of bull calves aged around 2 1/2 weeks. These calves were selected retrospectively according to their disease record up to six months of age. A clear association was found between low levels of IgG1, IgG2 and IgA in the "2 1/2-week" sample and subsequent susceptibility to pneumonia at around 2 1/2 months of age. Calves showing signs of pneumonia had low levels of IgG1 (45-5 per cent had less than 8 mg per ml compared with "now-pneumonic" calves which had relatively high levels (only 9.5 per cent had less than 8 mg per ml). In contrast, older calves bled at monthly intervals and found to have pneumonic lesions at slaughter had significantly evevated levels of both IgGa and IgG2.

Three monoclonal antibodies, specific for porcine IgG, IgM and IgA, were used to develop isotype-specific immunoperoxidase monolayer assays for the detection of antibodies against African swine fever virus. A mixture of anti-IgM and anti-IgG monoclonal antibodies was used in an assay designed for screening sera. This test was compared with a commercially available ELISA by using experimental sera and field sera obtained after an outbreak of African swine fever on two farms in the Netherlands in 1986. Although the ELISA was less sensitive than the immunoperoxidase monolayer assay on sera taken early after infection, the tests were equally useful for screening purposes. The isotype-specific assays gave epizootiological information about the stage of infection on the two farms.

The peroxidase anti-peroxidase technique was used to demonstrate free and intracellular immunoglobulin (Ig) within the lungs of 23 horses with chronic small airway disease. Histologically, all the horses had chronic bronchiolitis; however, the lesions varied in degree from mild in eight horses, to moderate in nine horses and severe in six horses. Lungs from three horses which had no gross or histopathological lesions were used as controls. In comparison with control horses, horses with mild chronic bronchiolitis had increased numbers of Ig A-containing and non-immunoglobulin staining cells around the vasculature and bronchioles. As the severity of the lesions increased so did the number of IgA-, IgG(Fc)- and in several cases non-immunoglobulin staining cells around the vasculature, bronchioles and in the alveolar septa. In severely affected horses, large amounts of free IgG(Fc) were observed interstitially and in alveoli. In areas of mucosal epithelial hyperplasia and metaplasia large amounts of free IgA and IgG(Fc) were sometimes observed interepithelially in a pattern which differed from that in control horses.

Forty-two previously untreated patients with multiple myeloma were entered in a prospective, randomised trial comparing recombinant interferon alfa-2C monotherapy with VMCP (vincristin, melphalan, cyclophosphamide and prednisolone). Both treatment arms were comparable for the stratification variables such as paraprotein type, stage of disease, and renal function. Rec. interferon effected 14% responses and 29% minor responses, while 57 and 32% of VMCP-treated patients achieved a pathologically documented remission (P less than 0.001). The time on initial treatment was significantly shorter in the IFN group (3.2 months) than in the VMCP group (7.6 months). In four patients in the IFN arm, primary treatment had to be changed according to progressive or severe stationary disease. Since all four patients responded to second line therapy (VMCP) no significant difference has been observed between the two groups in survival (median follow-up greater than 12 months). Despite this clear superiority of the conventional four-drug polychemotherapy, there was some suggestion that IFN might be particularly active in cases with low tumor-burden (stage I, II), and light-chain or IgA paraprotein type.

The distribution of lysozyme in the endocervix of estrous, pseudopregnant, and ovariectomized rabbits was studied using two different immunocytochemical techniques--the unlabeled antibody enzyme method of Sternberger et al. (1970) and the peroxidase-labeled antibody method of Taylor and Burns (1974). With both procedures, a fine immunostaining precipitate was seen over the entire area of basal mucous granules, while immunodeposits were coarser and mostly located in the outer zone of central and apical granules. A nonspecific staining was noted when tissues were reacted with peroxidase-antiperoxidase complex alone. This troublesome artifact was abolished by preincubating tissues with human IgA. This step did not affect the specific immunostaining for lysozyme yet nonspecific staining was absent from specificity and method controls carried out for both immunocytochemical procedures. The presence of high levels of lysozyme in the endocervical epithelium of estrous rabbits was also confirmed in enzymatically isolated endocervical epithelia using the lysoplate method of Osserman and Lawlor (1966). Mucous granules and immunostainable intracellular lysozyme were abundant during estrus, decreased during early pseudopregnancy, and were absent after long-term ovariectomy. However, they were restored by the administration of estradiol (5 micrograms/12 hours/10 days) to ovariectomized animals. These data indicate a common hormonal regulation and secretory mechanism for endocervical mucous glycoproteins and lysozyme.

Mice previously infected with an aerosol of A/Rec 31 influenza virus were strongly protected against an aerosol challenge with A/Vic influenza as judged by lung virus titers recovered 2 days after the challenge infection. Such complete homotypic immunity was not achieved by priming with live Rec 31 virus injected i.v. or UV-inactivated Rec 31 virus administered s.c. together with Al(OH)3 and saponin. The reason for the superior protective effect of the natural infection was investigated. The protection induced by respiratory infection with Rec 31 virus was specific for influenza A viruses. It was not correlated with specific serum hemagglutination inhibition antibody titer or cross-reactive cytotoxic T (Tc) cell reactivity. Moreover, the transfer of splenic and lymphoid T cell populations with strong secondary Tc activity did not significantly reduce lung virus titers in recipient mice 3 days after infection. The protection however occurred in parallel with the presence of cross-reactive IgA antibody in the lung washings. It thus appears that local secretory IgA plays a causal role in the prevention of cross-infection by influenza A virus. Serum antibody and Tc cells, on the other hand, may be crucial for recovery from such infection. All mice primed with live Rec 31 virus, administered i.v. or by aerosol and expressing equally high levels of Tc reactivity, survived a lethal challenge with A/PR8 virus. The same challenge, however, killed half of the mice immunized s.c. with inactivated Rec 31 virus which induced only a low level of Tc reactivity.

The development of lymphoid and nonlymphoid cells in Peyer's patches (PP) of the rat was investigated using light microscopical methods (routine histological techniques, enzyme histochemistry and immunohistochemistry). In newborn rats PP were mainly populated by T lymphocytes and Ia-positive nonlymphoid cells, which most likely are interdigitating cells. At about 12 days after birth the B and T cells were localized in defined regions, the follicular (FA) and interfollicular area (IFA), respectively. Compartmentalization within the FA started about 14 days after birth. The first signs of the development of secondary follicles were seen from about 18 days onward. PP obtained their mature structure at about 4 weeks after birth. It is suggested that after PP had developed fully, cells having cytoplasmic IgA migrate via the high endothelial venules (HEV) to the lamina propria of the intestine; cIgM and IgG cells seem to develop locally within the FA.

The total protein of colostral whey from dairy cows as determined by a refractometer were compared with the immune globulin concentration obtained by cellulose acetate membrane electrophoresis and the immunoglobulin (IgA + IgG + IgM) contents determined by radial immunodiffusion. The coefficient of correlation between the results obtained by refractometry and electrophoresis was 0.98 (P < 0.001). The correlation between refractometry and radial immunodiffusion was 0.89 (P < 0.001), while that of electrophoresis and radial immunodiffusion was 0.87 (P < 0.001). Refractometry can be used as a simple, fast and inexpensive indirect method of assessing immunoglobulins in colostral whey.
