Abstract:
The aim of this investigation was to study the transmission of Actinobacillus actinomycetemcomitans (A.a) between husband and wife when one of them was affected by acute juvenile periodontitis (P.A.J.). The hypothesis tested was the role played by the reservoir of the non-infected partner in explaining the frequent recurrences of the disease in the affected spouse despite combined antibiotherapeutical and surgical treatments. Twenty subjects with P.A.J. were studied. A.a. was found in the sub-gingival flora of nineteen of them. This micro-organism was also isolated in each of the partners of the nineteen patients. Each couple presented strains of the same biotype. The serotypes were studied in seven of these couples and confirmed the results of the biotypes. All theses results are in favour of the transmission of A.a. between partners.
Insights
Actinobacillus actinomycetemcomitans (A.a) transmits between spouses, with the non-infected partner acting as a reservoir. This transmission contributes to recurrent acute juvenile periodontitis (P.A.J.) despite treatment.
Area of Science:
- Periodontology
- Microbiology
- Oral Health
Context:
- Investigates the transmission of Actinobacillus actinomycetemcomitans (A.a) within marital dyads.
- Focuses on acute juvenile periodontitis (P.A.J.) and recurrent disease patterns.
- Explores the role of the non-infected spouse as a potential reservoir for A.a.
Purpose:
- To determine if A.a. is transmitted between spouses where one partner has P.A.J.
- To test the hypothesis that the non-infected partner's reservoir influences disease recurrence.
- To understand the microbial dynamics in couples affected by P.A.J.
Summary:
- A.a. was detected in 19 out of 20 P.A.J. patients' subgingival flora.
- A.a. was also isolated from the partners of all 19 affected individuals.
- Identical biotypes and serotypes of A.a. were found within each couple, supporting transmission.
Impact:
- Provides evidence for A.a. transmission between spouses in P.A.J.
- Highlights the importance of partner screening and potential co-treatment in managing P.A.J.
- Suggests that marital transmission may explain treatment-resistant or recurrent periodontitis cases.
