    Notizen: Abstract The intensity of male-to-male aggression, when evaluated in the laboratory, varies geographically in a subsocial spider mite, Schizotetranychus miscanthi Saito. This species includes two types of populations showing different clinal trends in aggression. We examined the relationships between the intensity of male aggression and the distribution patterns of individuals within nests for 22 field populations of the "low-aggression group." The intensity of male aggression was negatively correlated with the index of male aggregation across nests, which strongly suggests that aggression measured under experimental conditions is actually reflected in the interaction between males within nests in the field. The intensity of male aggression was also negatively correlated with the mean number of males per nest, suggesting that mortal fight between males, observed in the laboratory, actually occurs in the field.

    Notizen: Abstract Genital fulminant tuberculosis is rarely a primary site of infection. We report a case of juvenile adnexal tuberculosis possibly related to tuberculosis immediately after cystectomy in the ileocecal region in a virginal girl. A 13-year-old virginal girl visited our clinic because of a huge ovarian tumor, which was resected by cystectomy. On postoperative day 39, fever episodes were noted, and she received antibiotics, which were not effective. An abscess developed in the region of the cecum and the right adnexa. Laparotomy revealed chronic abscess formation, especially in the right adnexa. Resection of the abscess was done. The pathological diagnosis was tuberculosis with caseation, although bacterial culture and molecular biological diagnosis for Mycobacterium tuberculosis were negative in sputum, vaginal discharge, urine, and stool of the patient and her family. She was placed on anti-tuberculosis drugs, including isoniazid, rifampicin, and ethambutol, and this regimen was effective. This patient represents a rare case of fulminant adnexal tuberculosis without pulmonary disease.
