THE PELVIC VISCERA IN RELATION TO MICRO-ORGAN- ISMS IN HEALTH AND DISEASE. BY J. C. Weuhtkr, M.D., F.R.C.RE., F.R.S.K., Demonstrator of GyniecoloKy, McGlll University; Assistant Gyniecolo(j,ist to the Royal Victoria Hospital, Montreal. The bacteriology of the genital tract in various normal conditions : la the Mew-Born Child, in almost all cases, no germs are found in the vagina. Very soon, however, they enter, favoured by baths, washing, the application of oils, etc. Stroganoff states that a breech delivery of a female child favours their premature entry. Within the first two vveeks gelatine-liquefying germs are I'arely found. In Girls and Women various bacilli and cocci may be found in the vagina, as well as sarcinas, yeast fungus, eta One of these germs is very connnou and is called Doderlein's vaginal bacillus. The patho- genic organisms flourish best when the vaginal secretion is alkaline ; in acid conditions thej* are weakened in vital itj- or killed. As a rule no germs are found in the uterus or tubes. Menge has carried out an interesting series of experiments regarding the bactericidal proper- ties of the vaginal secretion in a large number of non-pregnant women. He introduced into the vagina a number of pathogenic organisms, viz. : bacillus pyocyaneus, staphylococcus pyogenes and streptococcus. In all cases he found that within 70 hours they had been destroyed or their virulence greatly diminished. He also carried out the following experiments. The vagina was carefully sterilised in the case of 70 women on whom abdominal section was to be performed. About 16 days after the operation the vaginal secretion was carefully removed and alkaline agar plates innoculated. In 62 cases the plates remained absolutely sterile. It was different, however, with specimens taken from the vulva for 06 of these gave I'ise to growths on the agar, only 4 being sterile. Of the 8 cases in wnich the vaginal secretion gave rise to growths, the germs were not pathogenic. In 12 cases acid agar plates were also employed, cultures being obtained in 6 cases (mostly consisting of bacilli); while in thr; same cases only 3 cultures were obtained on alkaline plates. (These few experiments are not, however, of particular value, for pathogenic geiins without exception develop in alkaline media and not in acid media.) s In another series of oxporlmonts, 12 in nuniher, lio used ^rape- sugar agar and obtained cultures 11 times, thus demonstrating the frequency of non-pathogenic anaerobic g' rms in the vagina. Doderlein has advanced the view that the micro-organism which he has called the " vaginal bacillus," of anaerobic growth, produces an acid secretion, which is the cause of the normal vaginal reaction and prejudicial to pathogenic organisms. Menge, however, believes that the vaginal secretion, whether ulka- line or acid is bactericidal to these organisms and he believes that the acid secretion of Doderlein's bacillus plays an unimportant part in the purification of the vagina. Of more importance is acidity due to other causes (found in the new-born child when no germs are present). But a considerable role is played by phagocytes and leucocytes which enter the vagina. The chief agents are, however, the anaerobic germs and their growth- products. In proof of these statements, Menge made the following experiments. He removed the acid secretion from the vagina in sterilised holders and innocuhited it with staphj'lococci. The latter were soon destroyecessary to specify these ; the germ which is of chief importance as an infective agency is the bacterium coli commune. Relaticn of Micro-organisms to Pelvic Diseases. — At the present time the tendency is to attribute the great majority of inflammations which occur in the peritoneum, cellular tissue and viscera of the pelvis to the action of micro-organisms. The inflammatory processes are simply, to state the modern view, the ser' 3S of phenomena caused by nature's resistance to the noxious influenciof the infecting organisms. These processes are, therefore, not evil in themselves, but are bene- ficoMt and purpoaeful. The most important germs which lu-t as intectiiifi; agents are : Streptococcus pyogenes (most frequent source of trouble). 8taphyh)coccus pyogenes aureus. Bacterium coli commune. The following are less often a source of trouble : Staphylococcus pyogenes albus. Staphylococcus pyogenes citreus. Staphylococcus epidermidis albus. Bacillus pyocyaneus. Diplococcus pneumonijB. Tubercle bacillus. These germs may gain entrance by the vagina, rectum, bladder, in- testines, or may be carried from some distant part by the circulation. The conflitions which favour their entrance are a favourable soil, e. g., a raw surface, a tissue of impaired vitality, a general condition of l)ad health in which the power of resistance of the tissues is reduced, dying organic matter such as blood-clot, remains of placenta or mem- branes. In some cases the micro-organism e. ,7., the gonococcus is capable of attacking the tissues and of setting up specific reaction when the individuals are in a state of perfect health. The most common source of entrance for the various germs is, undoubtedly, the vagina. They may .spread into the uterus and tubes and may infect the peritoneum and ovaries ; this may take place either by an extension of infective activity along the mucous membrane or by advance as a result of gei'm-development in a favourable medium lying within the genital cunal. They may enter a raw, injured or diseased surface and then spread to cellular tissue, peritoneum, tubes or ovaries, or even to more distant parts by means of blood-vessels and lymphatics. The exact relationship between germ-actif alkaline blood, more suitable for the growth of patlio- genie germs which might enter the vagina, and making it more easy for them to spread into the upper genital tract and attack the tissues. I It is poa.Hil)Ie, also, tliat such iiiflnonct's as chill nnd fati^iio. by diiiiin- ishirij,' the rcsiMtiii^ jxtwcr of the tissut's, reTi coitus, especially at inenstruatioii, is said to lead to iiiflaiiiniatory changes, espt cially in the uterus. There is, however, no proof that the mere physical excitement can induce these. Most likely it retpiirea to be combined with microbial activity; the irrita- tion of the tissues caused by the excessive movements in some measure depressing the vitality of the tissues and thus favouring infection by germs which might be present. When it occurs at the menstrual period there is also to be considered the altered naturi! of the vaginal secretion favouring the development of micro-organismal growth. In some of these cases, in which the inflammation is supposed to be due to coitus, gonorrhd'a is the infecting agent ; either an acute gonorrhoea existing in the man or a latent gonorrho'a in the man or woman. In the former of these the virulent trerm attacks the woman directly, its infectivity being unaffected by the action f)f coitus ; in the latter the latent condition is stirred into a rentiwal of activity as a result of the irritation and excitement of the excessive coitus. The Influence of La hour has long been regarded as tnost important among the factors causing pelvic inflammaticms. In the puerperium many conditions favourable to the development of micro-organisms are present. The vitality of the tissues in general is impaired as a result of the fatigue of the pregnancy and labour ; the uterus is weakened by its great exertion in delivery, the condition of its circu- lation is greatly altered owing to the contraction and retraction of its musculature, and its tissues are below their normal standard of strength owing to the puerperal retrogressive changes which take place in them ; the inner surface affords a large absorbing area; the placental site presents a number of opened blood-sinuses in which blood-clots are formed ; blood-clot often lies in the uterine cavity and. portions of the placenta and membranes may be left in it ; the cervix^ vagina and perineum are more or less bruised and very frequently lacerated. That the bruising and laceration per se can start an inflammation is very doubtful and, by many, is not at all believed. Were it not for the irritation of germs or their products, wounds would heal by direct union or by granulation, without the accompaniment of inflammatory processes. Certain other conditions in the puerperium are believed by many to lead to iiiflf^uimation, vi?.,tQQ eq/riy rising, wd by me. The manner in which the infection is brought about is not clearly known. In many of these discharges from the male urethra no gonococci can be found. Very probably, in such instances, the discharge may act by modifying the vaginal or uterine secretions so as to aftbrd a suitable medium for streptococci or other infective germs, which may spi-oarl iijiwards and lead to the various disturltanccs which 1 have described. Very often a perfectly healthy woman may be infected as a result of this latent gonorrli(i;al condir 18 tion in the male, the most distressing pelvic troubles developing sooh afterwards. Gonorrheal infection of the mucosa of the rectum may follow innnediately upon an infecting coitus, or it may afterwards follow as a result of the entrance into the bowel of gonococci from the vulvar discharges. Rarely it may follow rupture of a Bartholinian abscess into the rectum. The inflammation may be followed by an ulcerated condition. Bacterium Coli Commune. — This organism, first descrioed by Escherich in 1885, is believed to be the most frequent infecting microbe which may extend from the intestinal tract into neighbouring parts. It is of great importance in relation to general peritonitis, as has been shown by Treves and others, but it also plays some part in local pelvic inflammatory affections. According to the researches of Vignal and others, this organism is found in the whole alimentary tract. Nor- mally, it is believed to number about 95 per cent, of all the organisms in the bowel (Treves). According to Tavel and Lanz there are many varieties of this organism, and also corresponding diflTerences in its virulence. Accord- ing to the experiments by LeSage and Macaigne a culture outside the body is harmless and will not set up peritonitis when placed in the peritoneal cavity of animals, because under normal conditions the germ is not virulent. It may, however, become virulent under various conditions, e.g., in weakened, diseased or injured states of the wall of the gut, such as obstruction, strangulation, congestion, diarrhoea, compression, bad con- stipation, etc. If in such a condition of virulence, a culture of the germ be made, it has a distinct influence when placed in the peritoneal cavity of animals, varying according to the degree of toxicity. Thus it may only lead to slight constitutional disturbance with diarrhoea ; a localised purulent peritonitis may be set up ; or in some cases acute septicaemia may lead to death before any local signs of peritonitis are developed. P. Ziegler has pointed out that normally thr; bacterium shows no tendency to pass through the bowel wall ; if however, the vitality of the wall be impaired, in addition to becoming virulent, it at once begins to penetrate the wall and may extend into surrounding tissues for a considerable distance. When the bacterium reaches the peritoneum it may set up an inflammatory reaction varyiiip^ in extent according to its virulence (as well as other conditions). Paul Ziegler has shown that its activity is increased there, if fluids, 14 especially blood, be present in tbc peritoneum. It is also accentuntiKl, as Laruelle lias point(!(l out, if the intestinal secretion \n> present, even thouf^h the latter be artificially sterilised. This germ is generally the cause of peritonitis in hernial .sacs, in obstruction and 8tran;5uliition, in appendicitis ca.ses and other intestinal ccndition;.. Freshly filtered Huiil from the normal L.twel intnxluciMl i ito the peritoneum generally .sets up peritonitis. The cau.se is the bacterium coli. According to Barbacci the peritoneal endothelium is damaged by this fluid, thus favouring an infection by the germs ; and I have already pointed out that the activity of the microbe is increased by the presence of the intestinal fluid in the peritoneal cavity. If the fluid be in any quantity it has a depressing influence on the .system on account of the al)sorption of the toxins in it. The bad effect of fasces when introduced into the peritoneal cavity is due to the presence of microbes, especially the bacterium coii, in it. If sterilised fteces be introduced no bad I'esult follows. It is likely that a considerable proportion of local pelvic infections in women are due to this bacterium and it is possible that in nullipar- ous women the frequency of retro-uterine inflannnation is related, not to infection from the uterus in the great majority of cases, but from the rectum. The oviirstretching of the rectum from constipation, so conmion in women, the continual soaking of the wall in this state with toxic matters in the bowel-contents, the occasional occurx'ence of cracks and ulcers in the rectal wall are all factors which favour the passage of the bacterium coli into the utero-sacral ligaments, surrounding cellu- lar tissue and peritoneum and even the uterus. Tubercle BaciUun. — Tubei'culosis in the genital tract may be set up in a variety of ways. 1. It may be primary, i. by way of the vagina, being introduced V>y dirty instruments, liy examining fingers, by sleeping with a tubercular per.son, by coitus with a man suffering from genito-urinary tuberculosis. In such cases, the vagina and cervix may be first affected, the disease spreading afterwards along the uterine and tubal mucosa ; or the upper genital tract may sometimes be first attacked, according to Whitridge Williams, the bacilli entering a denuded surface on the vaginal wall and being carried up by the lymphatics. 2. The genital organs may become affected b^' the direct spread from neighbouring tuberculous areas, e. g., tuberculosis of bladder or bowel ; ulcers may perforate or abscesses burst leading to fistulous communications. 1» W. Willimns states that one of the most frequent sources of genital tubc'rcuh)sis is tubercular peritonitis. Weigert has shown that in this disease tlxe i)acilli which become free in the peritoneal cavity tend to sink into the pelvis settinjf up infection ; they are there in the best position to b" swept towards and into the tubes and they nuiy undoubtedly be carried into the tubes setting up disease without infecting th« pouch of ])i)V glas at all. 3. The bacilli may be introduced directly into the vagina when the patient has tuberculosis in some other region, e. ff., urinary tract, intestines, lungs, the infection spreading from tKe discharges. Kegar has pointed out that genital tuberculosis is rare in childhood and after tl\e climactei-ic. Infection by men suffering from genito-urinary tuberculosis is of considerable int
