[Submental abscess by Lactobacillus acidophilus/jensenii].

The different species of Lactobacillus genus are bacteria of a low pathogenicity. They are found in the gastrointestinal tract, the female genitourinary tract, and also as part of the anaerobic flora in the mouth. Due to this low pathogenicity, they are generally related with infections together with other with more virulent microorganisms, or in immunocompromised patients. In our case, Lactobacillus appears alone as an etiological agent in an immunocompetent patient with a submental abscess.

[Simultaneous occurrence of enterotoxigenic Staphylococcus aureus on the hands, mouth and feces of asymptomatic carriers].

One hundred and twelve asymptomatic individuals were analysed with regard to the simultaneous incidence of Staphylococcus aureus on their hands and in their nose, mouth and stools, in the city of S. Paulo (Brazil). A total of 40 (35.7%) individuals were detected as carriers of this microorganism. Among these carriers, 27 (67.5%) were positive in only one of the four niches studied, 8 (20.0%) in two and 5 (12.5%) in three niches. They were identified 113 Staphylococcus aureus strains, and 28 (24.8%) of these strains, isolated from 9 (22.5%) carriers, produced enterotoxin. Of these strains, 7 (25.0%) produced type A enterotoxin, 6 (21.4%) of type B, 11 (39.3%) type C and 4 (14.3%) produced both type A and C. The phage typing of the 113 Staphylococcus aureus strains revealed the predominance of the strains lysed by phages belonging to the Group I/III/NC (16.8%). The results obtained did not demonstrate the simultaneous incidence of Staphylococcus aureus strains in samples collected from mouth, hands and stools of the group studied.

[Clinical picture of recurring aphthae in the mouth mucosa].

Various classifications of recurrent aphthous ulcers, their differential diagnosis, especially the herpetic ulcers of the oral mucous membranes, are discussed. The clinical and histological pictures show three variants, the minor form, the major form or periadenitis mucosa necrotica recurrens (Sutton), and the herpetiforme aphthous ulcers. Recent investigations discussing the etiology of these ulcers assume that an auto-antigen might be responsible for the immuno-pathological mechanism. This auto-antigen is supposed to be formed by the contamination of the oral mucosa with microorganisms, particularly streptococci.

[Functional significance of "blind" outgrowths of the lymphatic capillary network].

The work was aimed at the study of the structural peculiarities of "blind" outgrowths of the lymphatic capillaries and to define their role in the pathogenesis of some diseases. In experiments performed in rabbits by studying the resorption of colloidal solutions, suspensions and hen's blood the subsidiary functional significance of the portion of "blind" outgrowths of the lymphatic capillary network of tendinous center of diaphragm was established. The clavate outgrowths with the narrow mouth may accumulate and store the exogenous material in their lumen. It is concluded that they may accumulate the microorganisms that provoke the relapses of diseases.

Immune surveillance of the oral cavity and lymphocyte migration: relevance for alcohol abusers.

The health of the oral cavity is threatened by a variety of microorganisms. Impaired immune surveillance of the oral environment contributes to the development of infectious processes and tumors of the mouth. Elucidation of the physiological mechanisms that determine and control oral immune surveillance is crucial to an understanding of these oral diseases. The ability of lymphocytes to migrate is critical for successful immune surveillance. the cardinal facets of lymphocyte migration are reviewed here in the context of the oral cavity. One mechanism by which alcohol acts as an important cofactor in the onset and development of oral diseases is hypothesized to be through impaired lymphocyte migration to and from peri-oral lymphoid tissue.

Colonization capability of lactobacilli and pathogens in the respiratory tract of mice: microbiological, cytological, structural, and ultrastructural studies.

Respiratory tract infections are among the bacterial infections that affect humans with higher frequency. Those produced by Streptococcus pneumoniae are reported to have the highest incidence in the world, affecting both children and old people. As a 2001 report from the World Health Organization expressed it, the basic fight of children under 5 yr old is to survive. Five different conditions (acute respiratory infections, diarrhea, measles, palludism, and undernutrition) directly produce more than 50% of the deaths in this age group. Respiratory tract infections in the developing countries in the Americas are among the first three causes of death in children under 1 yr and between the first and second cause in children between 1 and 4 yr old. Pneumonia is responsible for 85 and 90% of deaths in children under 5 yr old (approx 150,000 annually), 95% of them occurring in the developing countries in the Americas. There is an increased worldwide tendency to use preventive measures and to consume products that help to maintain the health status of the individual. Thus the use of probiotics has increased systematically during the last decade, and the scientific literature trying to demonstrate the positive effect of such preparations has also increased. The term probiotic has been applied to products that (1) contain live microorganisms, freeze-dried or included in fermented products or (2) improve the health status of humans and animals, exerting effects in the mouth or gastrointestinal tract (included in foods or capsules), in the respiratory tract (as aerosols), or in the urogenital tract (by local application)Having in mind the high incidence of respiratory tract infections, and looking for preventive measures as well as the possible applications of probiotics, the aim of this chapter was to use mice as experimental models to determine whether members of the genus Lactobacillus were able to colonize and give protection from infections after inoculation by the intranasal route. To this end, the following procedures were carried out: 1. Screening of the predominant bacterial species in respiratory organs. 2. Study of the kinetics of colonization of the different groups of microorganisms from 15 d up to adult (2 mo). 3. Screening of the probiotic characteristics of all the isolated strains.
