The experiments carried out demonstrate that under the influence of tetanus exotoxin, Gram-negative bacteria endotoxins, staphylococcal infection and infestation with Tr. spiralis, inhibition of the Pasteur effect occurs. Recently published data show that the same manifestation of pathogenicity is induced by diphtheria alpha and delta exotoxin, staphylococcal toxin, Pseudomonas aeruginosa exotoxin, staphylococcal enterotoxin, streptolysin O, infections with Cl. perfringens, Pasteurella and Rickettsia and hepatitis viruses in man. These data confirm a previous hypothesis according to which inhibition of the Pasteur effect represents the expression and metabolic measure of pathogenicity and toxicity. The inhibitory effect was proportional to the amount of pathogenic agent or toxin, just as the respective anatoxin or toxin + endotoxin mixture does not influence the Pasteur effect. The metabolic criteria of the Pasteur effect, i.e. inhibition of hyperlactacidaemia and decrease of the organic P/inorganic P ratio, are thus the direct indices of pathogenicity and toxigenicity. This also accounts for deep alteration of the Pasteur effect in infections generating states of infectious and endotoxinic shock.

In a period of 5 years, 8 out of 77 renal transplant patients showed simultaneous fungal, bacterial and viral infections. Candida albicans was found in all cases. The most severe bacterial complications were infections with Klebsiella, Pseudomonas and Staphylococcus aureus. Cytomegalovirus, persistent HBsAg positive hepatitis, herpes zoster, and herpes simplex infections were also found. Seven patients died of bacterial superinfection and miliary tuberculosis. The data presented show that "triple infections" are associated with high mortality and that miliary tuberculosis occurred frequently in immunosuppressed renal transplant recipients.

Botryomycosis is a disorder caused by certain nonfilamentous bacteria that produce lesions that resemble actinomycosis. We describe a previously well, young man who initially had apparent hepatitis due to Pseudomonas aeruginosa which spread hematogenously to involve both lungs. He was treated successfully with antibiotics.

B3 is a tumor-reactive monoclonal antibody (mAb) that binds to a limited number of normal tissues. Immunotoxins made with B3 coupled to either Pseudomonas exotoxin (PE) or recombinant forms of PE with a deletion of the cell-binding domain (LysPE40) have been shown to cause complete tumor regression in nude mice bearing a rapidly growing A431 (L. H. Pai et al., Proc. Natl. Acad. Sci. USA, 88: 3358-3362, 1991) human epidermoid carcinoma. In this study we show that an immunotoxin composed of mAb B3 when chemically coupled to LysPE40 (B3-LysPE40) led to complete regression of a slowly growing breast cancer, MCF-7, in nude mice when given i.v. every other day for five doses. mAb B3 coupled to native PE also produced significant regression of the MCF-7 tumor. The reactivity of mAb B3 was evaluated using an immunohistochemical method on the two responsive tumors, MCF-7 and A431, and compared with a typical human colon carcinoma specimen that has B3 antigen on its surface. The results showed that both A431 and MCF-7 xenograft tumors have similar reactivity to B3 when compared with the human colon carcinoma specimen. To evaluate the toxicity of B3-PE in primates, Cynomolgus monkeys received escalating doses of B3-PE i.v. on Days 1, 3, and 5. Based on antibody localization studies using frozen sections of normal human and monkey tissue, gastric, trachea, and bladder mucosal injury could have occurred. However, no clinical signs of injury or histological damage to these organs were seen at the doses administered. Chemical hepatitis due to PE was transient and well tolerated at doses up to 50 micrograms/kg for three doses. The lethal dose was about 100 micrograms/kg, and the cause of death was liver necrosis, as shown by necropsy. We conclude that mAb B3, when coupled to PE40 or PE, can produce strong antitumor activity in vivo. The similar level of reactivity of the B3 antibody in our tumor models with a surgical specimen of a human colon carcinoma and the toxicity study in monkeys indicate that therapeutic doses of B3-PE and B3-LysPE40 can be delivered without causing toxicity to normal organs that express B3 antigen. Although both B3-PE and B3-LysPE40 have antitumor activity in nude mice bearing a human xenograft, B3-LysPE40 is better tolerated and should be further evaluated as a therapeutic agent for cancer patients.

An attempt was made to reduce the risk of infection following liver transplantation by means of selective bowel decontamination with tobramycin, polymyxin E and amphotericin B, as well as short-term systemic antibiotics with cephotaxim and tobramycin. After 53 consecutive orthotopic hepatic transplants performed in 51 patients between 1985 and 1987, a total of eight pneumonias occurred as the clinically most significant infection. Two pneumonias were caused by cytomegalovirus, one by Pneumocystis carinii, one by Candida and the remaining four by various bacteria. In 6 patients, bacteria were cultured from the blood, but only in one case was an indwelling catheter identified as the source of the septicemia. Taking all samples together, Streptococcus faecalis was the bacterium most frequently cultured, which was not covered by the prophylactic antimicrobial regime applied. Pseudomonas, however, and gram-negative bacteria were demonstrated much less frequently. Vaginal and oral Candida infections, as well as oral and genital herpes simplex infections, responded well to topical therapy with fungicide and aciclovir, respectively. Three patients developed cytomegalovirus (CMV) hepatitis. All five CMV infections were successfully treated with ganciclovir and hyperimmunoglobulin, as well as reduction of prophylactic immunosuppression. Out of 15 patients transplanted for posthepatitic cirrhosis, 7 developed a recurrence of the infection (5 hepatitis B virus) 2 hepatitis C virus) in the graft. Two died of the cirrhosis, three are still alive with cirrhosis but sufficient graft function, and one patient is suffering from chronic active hepatitis. One patient grafted for acute hepatic failure was able to clear the delta virus within 1 year post-transplant.(ABSTRACT TRUNCATED AT 250 WORDS)

Homograft cartilage preserved in Cialit solution became contaminated with Pseudomonas fluorescens, making it unsuitable for reconstructive surgery. Cialit solution has no virucidal activity, and the risk of viral infections such as AIDS and hepatitis is a further reason not to use it as a storage solution for cartilage.

After major surgery some patients, especially those with an infectiouss process or sepsis, develop jaundice which has been called reactive hepatitis, toxic hepatitis, septic hepatitis or benign postoperative cholestasis; these terms do not have a very precise connotation. Eighty patients with postoperative sepsis and jaundice where studied, excluding those with liver or biliary tract disease, hepato-toxic drugs or repeated halogenated anesthetics. All of them had complete laboratory tests, cultures and percutaneous liver biopsy when it was feasible. Thirty five patients were submitted to percutaneous liver biopsy and they are the material for this paper. There was no correlation with the type and duration of the operation, postoperative complications, shock or kind of anesthesia. The main laboratory changes were leukocytosis, neutrophilia, elevation of the bilirubins mainly the direct type and increase of the alkaline phosphatase; transaminases were within normal limits. Cultures were positive in 76% of the cases predominating E. coli, Pseudomonas a. and Proteus, anaerobics were present in 22.8% of the cases. The liver biopsy showed lymphoctic infiltration, hyperplasia of the Kupffer cells, hepatic regeneration and turbid tumefaction; pericholangitis, focal necrosis, retention of pigment and steatosis were less frequent. We consider that the best denomination of these complications is benign postoperative cholestasis.

Epidemics account for a small proportion of preventable infections acquired in hospitals, but they have been important in defining sources, modes of spread, and methods for prevention and control of nosocomial infections. To characterize hospital-based epidemics, 265 consecutive outbreaks investigated by the Center for Disease Control between 1956 and 1979 were reviewed. Pseudoepidemics were found in 11 percent of the investigations, most often resulting from errors in processing microbiologic specimens or from surveillance artifacts. In 223 actual epidemics, the pathogens most commonly involved were Staphylococcus aureus (19 percent), tribe Klebsielleae (14 percent), Salmonella (13 percent), hepatitis B virus (8 percent), enteropathogenic Escherichia coli (5 percent), Pseudomonas (4 percent) and group A streptococci (4 percent). Sites of epidemic infection were closely linked to the responsible pathogens. Gastroenteritis (21 percent), skin infection (18 percent), bacteremia (12 percent), meningitis (11 percent) and hepatitis (10 percent), infrequent causes of endemic nosocomial infections, were frequently involved in epidemics. Over the 25-year period reviewed, staphylococcal epidemics and outbreaks of gastroenteritis due to Salmonella and Esch. coli declined in frequency and those due to gram-negative bacilli and hepatitis B virus increased. Since 1970, clusters of primary bacteremia were the most frequently investigated type of epidemic. Many epidemic strains of staphylococci obtained since 1975 or Enterobacteriaceae obtained since 1970 exhibited unusual drug resistance. Specific site-pathogen combinations were closely associated with characteristic reservoirs and modes of spread.

Fourteen mares and their foals were attended at parturition. After mare-foal bonding, 8 colostrum-deprived (CD) foals were removed from their dams, deprived of colostrum, and provided with an alternative milk source for the first 24 h of life. The mares were milked out every 2-4 h during this period to remove colostrum, after which the CD foals were returned to their mares and allowed to nurse. Six colostrum-fed (CF) foals were allowed to suck colostrum in the normal manner. Foal serum IgG concentration was determined by single radial immunodiffusion (means, CD = 0 mg/dl; CF = 1,508 mg/dl). Accepted methods were used to minimise infections in the neonatal foals. Of the 8 CD foals, 7 demonstrated clinical signs of sepsis. Septicaemia was confirmed in 5 of the 7 septicaemic CD foals by ante-mortem blood culture or by culture of tissue at necropsy. Organisms isolated included: Actinobacillus equuli, Escherichia coli, undifferentiated coliforms, Pseudomonas spp., and Actinomyces pyogenes. Clinically ill foals were treated with antimicrobial drugs, intravenous fluid therapy, flunixin meglumine, and anti-endotoxin hyperimmune serum. Three septicaemic CD foals survived. Four of 7 septicaemic CD foals died or were destroyed. Post-mortem lesions included bacterial embolic pneumonia, glomerulonephritis/nephritis, lymphoid depletion/atrophy, splenic and lymphoid necrosis, hepatitis, septic arthritis, and systemic bacterial embolism. None of the CF foals became septicaemic. One CF foal had foal heat diarrhoea and 1 CF foal had a serum IgG concentration of 160 mg/dl (i.e. failure of passive transfer), but both foals were otherwise normal.(ABSTRACT TRUNCATED AT 250 WORDS)
