Brief study of vaginal populations, the human vagina being considered as a biotopic cavity. Allusion to dynamic aspects ("vaginal climate", "landscapes") and to various bacterial populations. Introduction of the concept of xenoecies and of facies. This study is preceded by essential definitions of terms widely used in ecology.
Twenty patients admitted to hospital with serious lower respiratory tract infections entered an open study of 400 mg enoxacin given orally twice a day for a minimum of seven days. Clinical signs and symptoms were completely cured or improved in six of eight patients with pneumonia, in nine of ten patients with bronchitis, and in two patients with bronchiectasis. Enoxacin was effective in eradicating the initial pathogens in 10 of 12 patients with positive cultures. Enoxacin was well tolerated. Only one treatment-related side-effect was observed during the study. Nine patients received concurrent treatment with theophylline, but no signs of theophylline toxicity were seen. Enoxacin is a safe and effective alternative to parenteral treatment of lower respiratory tract infections.

The effect of Paragerm spray from either a hand pressurized can or from a general room mist device (MCR device) on mattress mite populations was compared with the effect of a control spray. After 1 month a reduction in mite population due to the cleaning procedures was evident in the control treated mattresses; Paragerm treated mattresses had significantly fewer mites, notably those treated with the aerosol can spray, nine out of fifteen of which were mite free. Dissection of the mattresses showed that some mites survive and they could form the nucleus from which reinfestation could occur.
Attempts to reduce the growth of house dust pyroglyphid mites by vacuum cleaning, and modifications of temperature and humidity are useful but not sufficient. Their absence in dust from hospital beds which are disinfected led the authors to test PARAGERM AK, a non toxic bactericidal and fungicidal spray. This proved highly effective as an acaricide, killing off cultures of Dermatophagoides spp. and other mites with acceptable and easily produced concentrations, thus providing a new way of combating the house dust allergy mite.

The authors sum up the principal morphological, biological and ecological characteristics of the human lice. Moreover they recall the therapeutic and prophylactic measures which could be used against them, and they bring to mind their "in vitro and in vivo" research technics on comparative effectiveness of certain insecticides against head lice.
The description of a case imported from Chad of an association of Salmonella typhi - Schistosoma haematobium and, in this connection, a new revised general account. The association Salmonella-Schistomas is wide-spread. It corresponds to a salmonello - schistosomo - micro - association by the fixation of precise bacteria in the case of a bacteriemia on the cutaneous surface of male schistosomes in clearly defined places. These Salmonella constitute a permanent antigenic solicitation and they are capable of mobilization and rejection (bacteriuria after passage through the blood-stream) whereas bacteriosis remains asymptomatic. In fact, on the practical level, a clear and absolute distinction must be made between:--the bacteriemia with the concomitant bacteriuria, which are largely physiological in nature, very frequent and originating from various germs, connected with the emunctory function of the kidneys and which can be observed in any subject.--the schistosomal bacteriuria which are specific entities and evidence of a veritable micro-association of a symbiotic nature between the Salmonella and the schistosome, a micro-association which the bacteriuria reveals unexpectedly whereas the clinical symptoms are absent, not clearly discernible or totally misleading.
