I; «h '9'“ f‘ A 11."; LwEMST 1033' Infant gastro~enteritis has been of interest to various investigators for many years. A multiplicity of suspected viral and bacterial agents has been cited as responsible for many deaths among newborn and infants. Humorous agents have been incriminated, sons of which have attracted the attention of workers on both sides of the Atlantic. Several years ago the question arose as to whether two special serotypcs or Egghgzichin gal; could be responsible for the disease. These types were often found to be the dominating organism in sporadic and epidemic infant gastro- enteritis. The two serotypes in question have been design netcd as 055 and Gill accorfiing to Keuffcsn (1950). Investi- gations in the past regareing the pethogenicity of many organisms have been questioned. Serious consiaeration has been given, therefore, to the toxic substances obtained from bacterial cells by chemical fractionation.netnods. The polysaccharides of 3. 9211. were obtained in 19:23 as a "resieue antigen“ by Zinsser and Parker. Their final product gave positive carbohydrate ans negative protein tests. It also precipitated homologous antisera, but was ins capable of inducing protective antibodies in rabbits. Soith (1927) confirmed this information. mt col dis ac‘ Boevin and Hesrobeanu (1937) prepared a glucolipid antigen fromufl..gg11. The bacteria were extracted in the cold with trichlorccetic acid and the residue rescued. After dialyzetion to remove the acid, the carbohydrate was precipi- tated with alcohol. This substance showed immunolog'cal activity 1.3 mg and in 213122. Wong (1933) isolated the polysaccharide of 2. 2211 and obtained fractions, first by acid hydrolysis and than by alkaline hydrolysis. The procedure consisted of a hydrolysis with two per cent acetic acid. The final sxtrection.was completed in alcohol. After drying the precipitate appeared as a fine white powder. A complete ch93 cal study revealed a substance which could be hyirolyzed by mineral acids to simple heroes sugars. The two fractions differed only in minor details. One of the early studies concerning the physiological effect of bacterial fractions upon the blood of rabbits was described by Dclafiela‘gtmal. (193%). A close parallel was shown to exist between fractions which were antigenic and the production of a hyperglyceuicvtoric state in.rcbbits. all fractions were assumed to contain rolysaocharides but no un- altered protein. The products were produced by tryptic di- gestion followed by alcohol precioitation. The greater the toxicity or the fraction, as demonstrated by injection into mice, the better immunizing agent it became when the some animals were given subsequent injections of the fraction. Eben rabbits sore inounizsd with the some antigen, further injections failed to profluce the chemical changes in th' blood foznfl to mcur in tho non-133330 oni.ssl. A octerisl was is slated by Dennis (1939) frora fa: “-rn1? ‘w “-6, l' infusion broth c' turos of ¢*_ by precip ta- tion'with alcohol. The as toriel we 9 not characterized cheni- cally as e polys min mrile, thou; h it proved to be non-protein in nature. The fraction produced leuoopenis in rabbits. The effect was more pronounced in reiucing the nuobcrs of poly- morphnuc cor lcri :ocytes a, though it res a; p;::ont that some of thoa.survivod the effects of the toxin. The lot“'cytcs sore not markedly affected in the insane animals, while in the non- immune serious leusopenic states were observed. Those re- actions suggested the possibility that the leuKOpenic of typhoid, which is accompanied by depletion of the myclopoiotic ele:sonts of bone marrow, might be due to t‘rxis fro ction. In sidition, the lock of inflammatory cellular infiltration in the vicinity of typhoid bacilli get e further suos tantiction. while working with the same organism as Dennis (on..gin. 1939) Horace (lQhO) isolated a substance from fi..tzahoa; which later (florgsn, 19hl) proved to be toxic for rabbits. The in m; destruction of leukocytes was used as a measure of toxicity. The toxic fraction was obtained by alcohol pre- cipitation from an aqueous solution of the disintegrated organisms and purified by dialyzation in nellonm nae 3333. Th resultant toxic material was traatad by tho 333333 of Savag (1?33) to renova the protein. A light gray colloidal solution'was obtained when the driad material was r3¢ 333333333 in distillad water. 0033333 13.3133 33v3 tha follov»i.3 results: ’31 333.3 ”3-33 NM {‘4’ $335 ' 3 h 2 1!- 1 5 50 0.5 k as 0.2 h 0 In rabbits, doses of O.h~to 0.5'36 per kg injected intra- venously caused prostration'with dySpnCa and marked diarrhea, terrinatlng in den 3h. Saith (1939) discovarea that, after five or six in- jactions of a typhcid filtrate into rabbits at a tima when the 331331 showed a very high titer of antibodies in the serum, thara vauld fDIIQW’a typical fall in the white blsod cell count. morgan (a;..gii. 1930) encountered similar result3 khan L W“ 31333 aanals r333 23d 32m 1rply to injaction with a similar fractloa. This change canstituted a 3131- nution in the nunbar of nautrOphilas. An int3r33ting point to be observed hero is that aniaals possessing a high an nti- body titor to the toxic fraction were not protected from further lyoio or noutrophiloo Upon subsequent injections of homologous antigen. The 1333033313 offset of bacterial fractions was summar- ized by Olitzki (1941) in four stato3ont3: (1) A gonoral loukoponio consisting of a decrease in both nontrOpnilos and lymphocytes; (2) LymphOpenic~loukoponia duo to a sharp do- oroaso in tho lymphocytes, ossooifi ed Ath an inorooso in the neutroghilos; (3) Poly33313oois 333 to 3 snarp rise in noutroghiles, associatei with a mild dooroaso in lvo§tooytosg (a) Gonoral leukocytosio due to a rise in all typos. It was dotorminod that a loukooonio resistance, which was due to the activity of noutrophilos to resist lysio by a toxic fraction, could be developed by active i3annization.with tho fr r3 @103. This was not noted in all bacterial fractions tested. A fraction was prepared by Favorite (1932) that,uyon in- jootion into human adult voluntoor3,o mused chills, favor and muscular acho, followed by 3 1333333313 which was almost ant rely due to a loss of noutrop hilos.

REVISE 0F LITSRETURE In reporting his famous work in 1886, Escherich describ- ed a now bacterium which was found to be present in the ins tostinol tract of ovary manual. 33 hold the Opinion tact diarrhoal discuss was due to c rcilstribution of intestinal forms uni not to a Specific pathogen. Investigations since have discovcrod strains of fi.‘ggli known.to incite disccso of diorrhocl nature when.prcscnt in tho iutcstincl tract of infants and expcriucntclly in adulto. (Lancet, leading article, 1932) Since tho condition of diarrhoa in infants can be pro- duced by many agents and clinical conditions, a clarifi- cation as to the various causes is necessary. Crowley at 31. (19%1) summed it up vary well by outlining six major catc‘ gorics into which any case could be placed. Tho first ina eludes those cases duo to an outbreak of 5313039110319 or dysentery. Such infections are easily idcntifiod and cause little troublo for the bacteriologist. The second group is characterized by a high mortality rate, a rapid Spread among infants with.locc of weight, anorexia, toxemia, diarrhea, vomiting, and dehydration. Adults arc not offoctcd. The third is one in.which one may see diarrhea but usually no vomiting. A fourth in which adults as well as children are affected seems to be common, and many times cannot be traced to any specific agent. The fifth type may be referred to as the influenzal, whore mothers of infants and the hospital staff are common victims. The last group is charac- terized by both adults and newborn showing stonatitis in con- junction with diarrhea. This group would suggest a viral etiology (Light and Hodcs, 19H3). Infantile diarrhea, more accurately termed gastro-enter- itis, has been recognized for many years as one of the im- portant causes of death in infants. Because of epidcaic which have occurred in many countries of the world, particu- larly associated with hospital wards where crowded conditions prevailed, much interest has been aroused regarding the cause. It was not until 19%5 that coliforn organisms were seriously considered as causative agents. All work incriminating such agents is not yet complete. There are still many workers who take a dim view of the situation, even though the evi- dence is overwhelming. ' The literature is abundant with references alluding to the causes of infant diarrhea. As early as 1392 Jonson.gt ,al. in Denmark reproduced a disease with diarrheal symptoms in calves. He further infected calves by feeding cultures of E. 2911 isolated from diseased calves. It was believed that races of E. coil existed which were pathogenic for young 1.4:. iii 4‘0 3, ‘4. U: . .. [fl 10 calves, even though strain 3 of suzh or3anisas tare present in all noraal aniaals. Lovell (1937) confirmed these findin3s and produced a connereial polyvelent antiserum against 2.323li. The sane technique was applied to human infants by Hamburger (1920) who claimed success with antisera prerared a3ainst,§. coll. His work was not confirmed by subsequ nt investigations. Shortly a ter Eaaburger's declaration, idem (1927) described eoliforn bacilli which he believed to be related to diarrhcal disease in calves. Referring to these strains as “Dyspepsia- Keli", he proffered a theo y of ”elinentary intoxication" and described coliform organisms as related to diarrheal disease. Following the above work, several e nperinenters prefer~ entially selected the filtrate of broth cultures for areal- nation. Filtratee from cultures isolated in connection a th cases of scouring calves were studied by Saith at 31. (1927) and were’found to be tonic for calves one month old when given intravenously. This was not true when the sane fil- tratee were injected intraperitoneally into guinea pigs, even when the dose, tor is for calves, was increased many times. Feeding large numbers of bacteria to guinea pigs and calves had no aooarer t effect. Smith 23 a1. (1937) furtr er discovered th at than certain strains of g. call from the ileum of calves suffering from diarrhea or secure were grown upon aa3 ar plates, nutat ions occrr‘ed in which capsular substance was 109 t, virulence was ll reduced, agglutinsbility was increased, as use susceptibility to phagocytosis by leukocytes. So to (192?) else studied the interrelations between bacterial toxins and capsular substance compared with normal protective factors in the guinea pig. finch confusion existed as to how each strain or different organise belonging to the coliform group could be specifically identified. A tisely clarification appeared when Stuart 3t 31. (1938) laid the grout were for subsequent separations of the colifore from other groups of bacteria. Accordirsly, or3cn¢ isms of the some genus c uld have vary as serologicsl re- actions end at the some ties be bioohosicelly insecureblo. Still attempting to discover the ccusstive agent of disrrseel disease in infants, Crowley at 31. (19hl) cresised the flora of 57 cereal infants. Their results revealed 80 per cent ngtggggilxagflhizijgs, 10 per cent colifore bacteria, h per cent streptococci, and h per cent staphylococci. In comparison, 3% infants ill with s dierrhesl disease in two different outbreaks showed lectobecilli, 30 to 50 per cent, coliforu, 31 to 55 per cent, with streptococci end staphylococci exhibiting little change. An 3..32;1 etiology was not suspected in hose outbreaks, but it seems signifi- cant that the colifore organises increased at the expense of other species present in normal stools. in increasing number of workers began to observe out- breaks of gsstro-esteritis in infects, arriving at little by cy of a definite cause.

It was only natural, in the absence of a Gorinite agent, to cxolain the epiéoaic in terms of some'virus. Lyon.and Folsoo.(19%l) correlated outbreaks of epidemic diarrhea among newborn babiee with the simultanoous occurrence of virus influenzao among adults. Light and noies (19h3) were the first to isolate a filtereble agent from diarrheal stools of infants and to produce a disease in young calves by nasal alainistretion of the virus. Other atteoots to produce diarrhea experimentally with a virus were made by Buddingh and Dofid (19%“). An attempt was made to produce diarrhea in.rabbits by feeding 8&8?0n31038 of experimentally infected cornea from other rabbits having clir cal eye infections. After an incubation poriod of sovea days the animals doveloyed characteristic diorrhoel stools. when portions of these stools were fed to normal rabbits, no symptoms were observed. The'viral agent which.wos supposed to be the cause of the corneal infection'uae also credited with producing both atoaatitis and diarrhea in infants. Swabs, taken from the stool of diarrheal infants, proiuced a disoaso of the cornoa'when,rabbits were exocrimcntally in- fected. I. “hall P Eloir1n -*.QL.

For example, Keitell (1930) in the course of a study concerning an epiiemic of diarrhea a fee tine both afiults and infants, discovcrod that in many cases the infants‘ sora gave increased titers to cold agglutinina and streptococcus H. 6., both finding 330sting to hi3 a virus infection. He did not attempt to isolate a viral agent. Tho ghiqolig and figlggsolla gonora, along with many other bacteria, have been suspected as tho roSponsiblo agents in infant gastro-ontcritis. Anong those are the paracolon group (i-iushin, 19%), the gonna {3,32,12,33 (i-iushin, 19:30), the gomis 3'11»?- « , (2311921111, 1932), “Atom £111.31: (1.111.). and W m: r '1 W (11111.). Grannpositivo bacteria have played a minor role in the causation of diarrhea in conpnrison with grnnsnogntivo. Such organisms that have attracted some attention have been tho staphylococci (Kortyn 19kg, Crowloy at 31. 1?h1, and Draper .£&.al. 19h1), and the streptococci, certain strains or which were shown by 6119 (19%“) to produce enzymes changing tyro- sine to tyranino.

(1949) in a similar investigation found no such lesions in a large masher of cases. fistula (19h3) carried out extensive studies noon infants deed of a diarrnonl disease in usieh 0111 and 033 were the suspected agents. The pathological findings closely parallel- ed tnose found by others mentioned above. “he intestines manifested little change with no ulcers of the mucosa and only slight lymphedenoyethy of the mosenteric lymph glands. Only the liver consistently showed pathological changes. Host marked were fatty chance, congestion, and jaundice, in that order. the fatty changes appeared peripheral in the liver lobulo. There was usually evidence of early prolifer- ation of the cells forming the bile cannlieuli. The thynus gland was smaller in every case, as were the supra-rennls in some cases. A spleennmegaly was observed in sose. finphysemn of the lung with atelectasia was noted in four cases. Th so general findings only indicate a toxemia and wasting co.- dition and are in no way specific for any given disease enti- ty. These find n33 are not uncommon to many wasting diseases of children. in examination of infants deed free a dierrheal disease was made by Kirby.gifln1. (1950). In four of the patients no gross changes were observed in the intestines, other than a congestion of the mucosa. Hesenteric lymph nodes were normal or only slightly enlarged. there plasma and protein hy~ drolysetes were given as treatment, little fatty change was noted in the liver. Changes in the brain were limited to mild congestion of the pie-oroohnoid vessels and edema of the meninges. There were no lesions to compare with those found by Christensen on. m. (19%). Few other investigations have been node in the cose of known coldenics of 0111 or 055 intent gastro-entoritis.

From the results of he chemical examinations shown (Table I), it can be reasonably concluded that there is a carbohydrate nucleus present. Intact protein is not present as indicated by the absence of the gelatinous layer, figzgg ‘et‘al..gn.‘git. (1938), and repeated negative Binret re~ actions. Ritrogen-containing compounds, probably peptide in nature, are pr-ooot to an opyrooioblo extant. Tho poroon a; of nitrogon present in o=oh preparation (as noted in ?ablo I, column 3) is high.vhon.co:parod with polysaoohoriao fractions of others such as'fiong‘gt,gl. (1933).

It shouia bo brought to mind that tho presence of vari us ohoniooi constituents in poiyoaoohorido fractions doponfls greatly upon the method of isolation, and no results can be compared on on equal basis unless tho sage strain of organism is fractionotod and the Safia method of oz rootion is employofl. Tho chemical subst;noos that can be isolated from a givon organism, evon'by a single method of isolation, aro numerous and should not be cougarod with those isolated by other motooao.

A #2 per cent reduction in the total numbers of leuko- cytes occurred compared to the nunber present in the control sample. The neutrophiles were reduced 83 per cent, while the lyrphocytes showed a 35 per cent apparent increase. The pclynorphnuclear cells observed in blood films made at the termination of the incubation period were interesting. These cells were found in various stages of dissolution. Some appeared greatly ballooned and others appeared broken, with a pouring out of the granular material. Other cells possessed only a nucleus; the cytoplasm had passed out through the fractured cell w. . The cepious amount of debris found was accounted for by the fracture of the leukocytes, in this case neutrOphiles. Lymphocytes appeared essentially normal; only a few showed any alteration in morphology. The erythro- cytes were intact in all samples observed. Agglutination and Precipitation Tests Following the preparation of antisera, made by injecting a rabbit with the polysaccharide from 0111 or 055, it was necessary to deternine if the antisera contained both the somatic O and the "envelope" B antibodies. As a pure 3 anti- serum has never been prepared, it was thought that possibly #6 one made by injections of polysaccharide would be free of 0 antibodies. To investigate this possibility an experiment was made in.which an antiserum was prepared by injecting a mixture of 0111 polysac chariie and organises, that had been previously boiled (0111 or genie as), into a ratbit, while a seco.d rabbit received on ly the polysac cEL rile. If he pol;'- saccharidc were pure B anti3en, only 3 antibodies would be producei. By the sc.e rule, f the polysaccharid a were pure B anti3on, nixir’ it with a boiled culture would supply an anti3en complete with both 0 and B anti3ens. Such an antigen when injec ted into a rabbit telld res alt in an antiserun having both 0 and“ c antibod -es. The results of such an experiment can be scan in? able VII. is is evident, the boiled organisms were agglutinated in a l to 2553 dilution by the polysaccharidooccll vaccine entice 3, tr e unheated to l to 320 dilut -on. Antisera pro: pared against the polysaccharide alone agglutinated the boiled or3anisns in a l to 6&0 dilution. had the polysac- charido antiseruc contained o.ly3 u33.; lutinins, it would not have a331utinated the boiled or anisns, whim Inessessod only 0 anti3en u. The B anti3en on the bacteria had been destroyed by boiling for one hour. (Kauffnan, 1950) It ea c, horef o: e, concl adei that the polysaccharide was made up of both 0 and B anti3ens. Having established that tn polysacchariie was as do up of both 0 and 3 ant i3ens, whach.upon injection would produce 1+7 0 and B e3glutinio s, a pr ooipitction recoticn.wcs inn sti- .ct~3 tor iotcr:cinc if the 03 anti3 n of he poiysccchnrile would precipitate cell vaccine onticcrc possessing 03 preoipi~ ‘I i: s, as well as those hesin3 only 0 precipitins.
