We have isolated from Bordetella
pertussis
an oligopeptide with characteristic amino acid composition. This peptide was applied to mice in standardized tests for
pertussis
immunization. In three tests with three independent isolates of peptide, a significant and dose dependent protection was observed. One microgram of peptide per mouse produces the same protective effect as 0.1 IU of
pertussis
vaccine. It is important to note that similar peptides can be isolated from other bacteria and other DNA containing cellular organisms which have specific amino acid compositions and which are antigens specific for the organism from which they were isolated. The antigens are very potent, e.g., one ng of Mycobacterium
tuberculosis
peptide is equivalent to one unit of tuberculin. It is conceivable that immunizing effects such as those observed for
pertussis
are common to the peptides of this group. Since all such peptides are isolated from a group of low molecular weight ribonucleoproteins, as first reported by WILHELM, we propose the term nucleopeptides for this group. Oligopeptides of the nucleopeptide group are now available for sequence analysis. We expect that synthetic peptides of this group will become available in time for diagnosis, prophylaxis and therapy of a number of diseases.

The expanded programme on immunization feasibility studies is currently running into its second year of operations. The objectives of the study are to test the possibility of increased coverage using both fixed centre and mobile field teams for the vaccination of children under the age of 2 years against measles, poliomyelitis, diphtheria,
pertussis
,
tuberculosis
and smallpox and also to test the immunological response to two doses of
pertussis
and two doses of oral polio. Reports so far indicate some success in the areas of training and manpower development as well as the development of the cold chain system which is considered to be the most important requirement for an efficient, expanded immunization programme. It goes without saying that the progress of the study has been marked by some technical, social and administrative constraints.

The Indian government set up an integrated child development services (ICDS) scheme in 1974, the object of which was to provide health care that would reduce mortality, morbidity, malnutrition, and preventable disease among India's 228 million children (according to the 1971 Census) under the age of 14. The paper describes what this program consists in and summarizes its achievements in one area from July 1976 to December 1977. These have been: 80% of the children in the age group 0-6 immunized against diphtheria,
pertussis
, tetanus,
tuberculosis
, and smallpox; 60% of expectant mothers immunized against tetanus; 40% of the children and 30% of the mothers have received Foliper tablets, supplied to prevent nutritional anemia; 60% of the children have received 1 dose of vitamin A in oil and 40% have received their second; and, finally, 82% of the children have received a health checkup and 70% of the expectant mothers have received antenatal checkups. In addition, 20 indigenous dais have been trained and 20 more are presently undergoing training.

The vaccination status was investigated in 1482 patients between the ages of 1 and 14 years admitted to hospital with scarlet fever. Most of the patients were vaccinated against
tuberculosis
(97.7%), diphtheria, tetanus and whooping-cough (95.3%) and poliomyelitis (94.1%), relatively few against measles (21.1%) and very few indeed against mumps (0.7%) and tick-borne encephalitis (1.9%). The booster vaccination against tetanus and diphtheria had been omitted in more than 40%. Although the beneficial results of vaccination against
tuberculosis
, diphtheria-
pertussis
-tetanus and poliomyelitis remained more or less the same, the tendency towards vaccination did not spread as might have been anticipated. On the contrary, the extent of vaccination decreased, especially during the past years. In the same way the tendency towards vaccination against measles showed a sudden slowing down after a period of rapid increase. This implies that vaccination of children does not tend towards perfection. The vaccination rates differ widely between foreign children living in Vienna and natives. Although the foreigners show a similar vaccination distribution pattern as the natives, the numbers of unvaccinated children are much higher.

Various workers, including T. D. Stewart, claim that the aboriginal Americas were relatively disease-free because of the bering Strait cold-screen, eliminating many pathogens, and the paucity of zoonotic infections because of few domestic animals. Evidence of varying validity suggests that precontact Americns had their own strains of treponemic infections, bacillary and amoebic dysenteries, influenza and viral penumonia and other respiratory diseases, salmonellosis and perhaps other food poisoning, various arthritides, some endoparasites such as the ascarids, and several geographically circumscribed diseases such as the rickettsial verruca (Carrion's disease) and New World leishmaniasis and trypanosomiasis. Questionably aboriginal are
tuberculosis
and typhus. Accordingly, virtually all the "crowd-type" ecopathogenic diseases such as smallpox, yellow fever, typhoid, malaria, measles,
pertussis
, polio, etc., appear to have been absent from the New World, and were only brought in by White conquerors and their Black slaves. My hypothesis is that native American medical care systems--especially in the more culturally advanced areas--were sufficiently sophisticated to deal with native disease entities with reasonable competence. But native medical systems could not cope with the "crowd-type" disease imports that struck Indian and Eskimos as "virgin-field" populations. Reanalysis of native population losses through a genocidal combination of diease, war, slavery and attendant cultural disruption by Dobyns, Cook and others strongly suggest that traditiona estimates underplayed the death toll by a factor of the general order of ten. This would make for an immediately pre-contact Indian population of some 90-111 million instead of the tradition 8-11 million. Evidence is growing that Indians may have been no more susceptible to new pathogens that are other "virgin soil" populations, and thus their immune systems need not be considered less effective than those in other people. Present-day high mortality rates in Indians of both continents from infectious disease imports may be more socioeconomic than anything else.

Experimental autoimmune encephalomyelitis (EAE) was induced in inbred and congenic strains of mice by injection of mouse spinal cord homogenate (MSCH) in Freund's complete adjuvant (FCA) with
pertussis
vaccine. Genetic analyses showed that susceptibility to EAE in mice was inherited as a dominant trait and was in part controlled by genes located in the centromeric half of the H-2 complex. Mice with EAE developed cell-mediated immune responsiveness to basic protein of myelin (BPM), as judged by the macrophage migration inhibition assay, using peritonealyexudate cells; this was not observed with mice of resistant strains. However, the migration of peritoneal exudate cells of both susceptible and resistant strains was significantly inhibited in the presence of purified protein derivative (PPD) of M.
tuberculosis
. Thus, the genes involved in the control of susceptibility to EAE also influence T cell responsiveness to BPM. Antibody to BPM, as judged by radioimmunoassay, was detected in susceptible and resistant strains but there was no correlation between the presence or levels of antibody and susceptibility or resistance to EAE. It is suggested that resistance to EAE is associated with failure of T cells to recognize and/or respond to the encephalitogenic determinant of the BPM molecule.

An earlier report on the Nigerian expanded programme on immunization (EPI), covering 1974-1988, failed to demonstrate a clear-cut impact of the programme. This report attempts to determine the effectiveness of EPI in Borno State, Nigeria. We analysed trends in routine notifications for diphtheria,
pertussis
, tetanus,
tuberculosis
, measles, and pneumonia, from 1985 to 1991; data on poliomyelitis were excluded because of poor documentation, while we included data on pneumonia for comparison. We also performed a before (1983-1987) after (1988-1991) comparison in terms of the intensifications of EPI by age-specific strata amongst paediatric hospitalization for all EPI diseases at the University of Maiduguri Teaching Hospital, the sole referral hospital for childhood infectious diseases. Our results show an apparent reduction in morbidity from diphtheria,
pertussis
, tetanus, measles and pneumonia, and this was particularly prominent following intense vaccinations between 1988 and 1991. The reduction in these EPI diseases and pneumonia occurred despite the prevailing adverse socioeconomic conditions, and the absence of a specific control strategy for pneumonia in Nigeria. On the other hand, in spite of national BCG coverage of about 90% there has been a recent (1989-1991) increase in the registered cases of
tuberculosis
in infants and older children in Borno State. There is a need to intensify other intervention measures alongside EPI activities.

Infectious agents have often been implicated in the etiology of autoimmune diseases. Here we show that bacteria may also play a role in resistance to autoimmune diseases. SJL/J and (SJL/J x BALB/c)F1 mice are genetically susceptible to induction of experimental autoimmune encephalomyelitis (EAE), a murine model for human demyelinating autoimmune diseases such as multiple sclerosis. We studied the effect of several bacteria on the development of EAE and found that exposure of SJL/J or (SJL/J x BALB/c)F1 mice to Mycobacterium
tuberculosis
or Bordetella
pertussis
consistently rendered mice highly refractory to subsequent induction of the disease. Other bacteria such as Escherichia coli, Shigella and Staphylococcus aureus were found to be less effective, or were protective only if specific immunization procedures were used. Furthermore, M.
tuberculosis
and B.
pertussis
were protective irrespective of the route of administration and minute amounts (as low as 0.5 micrograms) of M.
tuberculosis
were sufficient to protect EAE-susceptible mice against induction of the disease. Interestingly, these bacteria, which are commonly used to promote development of EAE, conferred the highest degree of protection against the disease. The M.
tuberculosis
-induced protection was found to be associated with active suppression mechanisms mediated by T lymphocytes capable of transferring protection to naive syngeneic mice. These findings indicate that certain bacteria may protect against the development of autoimmune diseases. These results also suggest the potential use for still-unidentified bacterial agents in the manipulation of certain autoimmune diseases.

Two peptides, designated L and K, covering a sequence near the NH-terminal end of the S1 subunit of
pertussis
toxin (PT) were conjugated to the PPD (purified protein derivative) of M.
tuberculosis
by either glutaraldehyde (GLUT) or succinimidyl 4-(N-maleimidomethyl) cyclohexane-1-carboxylate (SMCC) and N-succinimidyl 3-(2-pyridyldithio) propionate (SPDP) and injected into groups of mice and guinea pigs. Initially, the effect of priming the animals with BCG vaccine and the use of aluminium hydroxide as adjuvant for the anti-peptide antibody response was studied. The group of BCG-primed mice immunized with adsorbed peptide conjugates showed the highest anti-peptide conjugate antibody response. Based on this finding, groups of BCG-primed mice were immunized four times with either adsorbed peptide L-GLUT, peptide L-SMCC/SPDP or peptide K-SMCC/SPDP conjugates and the fine peptide specificity as well as the PT and S1 cross-reactivity was investigated in ELISA. Mice immunized with peptide L-GLUT showed a significant antibody response to the homologous conjugate, only, whereas the group injected with the peptide L-SMCC/SPDP conjugate gave a significant response to both peptide K and L conjugated by the SMCC-SPDP method. Likewise, mice immunized with the peptide K-SMCC/SPDP conjugate reacted with the homologous and peptide L-SMCC/SPDP conjugate, although only the response to the former conjugate was significantly greater than the response to PPD. All groups showed a strong anti-PPD response. The anti-PT/S1 cross-reactivity of the antisera varied considerably within each group but was found to be highest in the peptide L-GLUT-immunized animals. The results of the present study not only stress the importance of BCG priming and use of aluminium hydroxide adjuvants for the immunogenicity of the peptides in question but also point to the specificity of the conjugation methods employed as low cross-reactivity between the anti-peptide L-GLUT and L-SMCC/SPDP antisera was noted. Moreover, it appeared that the choice of conjugation method may have an effect on the ability of the peptide conjugates to induce an antibody response cross-reacting with the native protein.

Increasing numbers of immigrants from the former Soviet Union are settling in the United States each year, making it imperative for clinicians to know how to find and interpret immigrant children's immunization records. Records show that these children have usually received immunizations against tetanus, diphtheria,
pertussis
, poliomyelitis, measles, mumps and
tuberculosis
(BCG). They are occasionally vaccinated against influenza, smallpox and tularemia, but never against rubella, hepatitis B or H. influenzae meningitis. The Soviet immunization schedule differs significantly from the U.S. schedule only in BCG vaccine and polio immunization. Contrary to widespread belief in the United States, BCG vaccination does not necessarily render a child's tuberculin skin test positive, and it certainly does not confer total immunity to
tuberculosis
. MMR vaccination is essential for all Soviet immigrant children. A single update of all the other immunizations may be a wise approach when handling Soviet children's immunizations.
