Plesiomonas shigelloides is a gram-negative, facultatively anaerobic rod whose appropriate taxonomic position is presently under investigation. The isolation and identification of this microorganism in contaminated specimens (e.g., feces) by a clinical laboratory depend on the screening of gram-negative colonies for oxidase and indole positivity and the appropriate use of selective and differential agars. Plesiomonads have been associated with extraintestinal diseases (bacteremia, meningitis) on rare occasions; they have been recovered sporadically from patients presenting with acute gastroenteritis. Although case reports and epidemiologic data support a role for P. shigelloides in diarrheal disease, laboratory investigations have failed to identify an enteropathogenic mechanism in these bacteria consistently or to reveal an animal model that faithfully reproduces the disease. Moreover, studies with volunteers have failed to establish an etiologic relation between Plesiomonas and bacterial gastroenteritis. An accurate picture of the role of this bacterium in human disease must await future studies.

The antibacterial efficacy of some of the newer quinolone antimicrobial agents in general, and ciprofloxacin in particular, in animal models of experimental septic arthritis, burn wound sepsis, empyema, chronic gastroenteritis, granuloma pouch infection, intraabdominal abscess, osteomyelitis, prostatis, sinusitis, urinary tract infection, and severe septicemia caused by Pseudomonas aeruginosa is reviewed. In addition, the efficacy of these newer quinolones has been studied in animal models of pneumonia, endocarditis, meningitis, skin and soft tissue infections, and a variety of other systemic infections. Although certain limitations are associated with animal models of infection, properly performed studies clearly have the potential to provide guidelines for evaluating the efficacy of antimicrobial agents in the treatment of some infections in humans.

A prospective study was done to determine the incidence of serious illness in children under two years of age with hyperpyrexia (temperature of 41.1 degrees C [106 degrees F] or greater). Nineteen children were seen and followed in the emergency department of Oklahoma Children's Memorial Hospital over a one-year period. The final clinical diagnoses included acute otitis media, pneumonia, acute gastroenteritis, roseola, and cellulitis of the leg. In the entire group there was no meningitis or subsequent death. One child was hospitalized. The statistical analysis (binomial test at the 0.05 level) confirms that the incidence of serious illness manifested only by high fever is no higher than 0.15. The mere presence of very high fever does not necessarily indicate a serious illness. Laboratory and other diagnostic work-up and hospitalization should be based on clinical evaluations, rather than done routinely.

The clinical features and laboratory findings of 78 cases of methyldopa fever are reported. This drug reaction masqueraded as a variety of acute infectious diseases including septicaemia, meningitis, hepatitis and gastroenteritis, occurred within five weeks of starting the drug and appeared to be unrelated to its dosage. Eosinophilia and skin rashes were conspicuous by their absence. In the majority of patients, symptoms were relieved within 48 hours of the withdrawal of the drug. Sixty-one per cent of patients had biochemical evidence of liver damage but jaundice was uncommon. This pattern of mild hepatotoxicity in patients with early febrile reactions to methyldopa contrasts with the later more serious viral hepatitis-like illness due to the drug.

Penetration of aspoxicillin (ASPC), a new semisynthetic penicillin, to cerebrospinal fluid (CSF) and clinical studies against bacterial infections were carried out and the following results were obtained. The concentration of ASPC in CSF was below 1 microgram/ml at 1 hour after intravenous administration of about 50 mg/kg dose to 2 cases of aseptic meningitis on the acute stage. The concentration of ASPC in CSF was above 10 micrograms/ml at 1 hour after intravenous administration of about 80 mg/kg dose to 3 cases of purulent meningitis on the acute stage, and was above 2 micrograms/ml even on the recovering stage. On each stage, its concentration was more than minimum inhibitory concentration of H. influenzae (less than or equal to 0.05 microgram/ml; at inoculum size of 10(6) cells/ml). Clinical efficacy of ASPC was good in all 3 cases of purulent meningitis, excellent in 3 cases, good in 3 cases and poor in 1 case out of 7 cases of septicemia, good in 2 cases and poor in 1 case out of 3 cases of gastroenteritis, respectively. And clinical efficacy of other diseases were excellent or good, that were 2 cases of tonsillitis, 2 cases of soft tissue abscess, 1 case of purulent lymphadenitis and 1 case of urinary tract infection, respectively. Side effects were mild eosinophilia in only 2 cases out of 22 cases.

Between October 1980 and August 1982, 100 patients in the pediatric population at Curran Lutheran Hospital, Zorzor, Liberia were identified as having multiple drug-resistant Salmonella enteritidis serotype enteritidis. The illness usually presented as an enteric fever but also as meningitis, gastroenteritis, empyema, subcutaneous abscesses, chronic otitis media, or a combination of these conditions. Predisposing factors were young age and debilitation from malnutrition or measles. The mortality of infected patients was 27.8%. The organism was originally misidentified as a Citrobacter species because of a delayed reaction on lysine decarboxylase medium. Incubation of the medium for five days resulted in a positive reaction that identified the organism as a Salmonella species. The isolates were resistant to multiple antibiotics. Genes mediating resistance were located on a 120-megadalton conjugative plasmid. A cryptic nonconjugative 40-megadalton plasmid was also present in several isolates.

Blood leukocytes from 37 patients with acute bacterial infections, and cerebrospinal fluid (CSF) granulocytes from 12 patients with bacterial meningitis, were examined for the distribution of membrane receptors (R) for (1) untreated sheep erythrocytes (E), (2) the Fc portion of IgG (Fc gamma), and (3) complement component C3b. We found a decreased percentage of granulocytes bearing Fc gamma-R in the CSF from patients with meningitis, and in blood from patients with respiratory tract infections. This group also had a decreased percentage of C3b-R bearing granulocytes on admission, whereas meningitis patients had lower levels of C3b-R and Fc gamma-R bearing granulocytes in the 2nd and 3rd week and even later. Several patients with meningitis and gastroenteritis had granulocytes bearing the E-R, previously considered specific for T lymphocytes. Such cells were also found in the CSF. Meningitis and respiratory tract infections were associated with a decreased percentage of 'active' T lymphocytes. The total percentage of T lymphocytes was also decreased in meningitis. Conversely the proportion of Fc gamma-R bearing lymphocytes (consisting mostly of B lymphocytes) was increased in most infections. During the first 3 weeks of bacterial meningitis, the percentages of Fc gamma- and C3b-R bearing granulocytes, and of Fc gamma-R bearing lymphocytes, gradually decreased, while the T lymphocyte percentage increased from the initial low values.

The penetration of aztreonam (AZT), a new synthetic monobactam, into cerebrospinal fluid (CSF) and the clinical studies for bacterial infections were carried out. The following results were obtained. The concentrations of AZT in CSF were less than 0.31 microgram/ml and 0.42 microgram/ml, respectively, at 1 hour after intravenous administration of 34 mg/kg and 71 mg/kg in 2 cases of aseptic meningitis at the acute stage. The concentration of AZT in CSF was 6.9 micrograms/ml at 1 hour after intravenous administration of 100 mg/kg in 1 case of purulent meningitis at the acute stage and was 0.62-0.98 micrograms/ml even at the recovering stage. At each stage, its concentration was more than the minimum inhibitory concentration of E. coli (0.10, less than 0.05 microgram/ml; at inoculum size of 10(8), 10(6) cells/ml). Clinical efficacy of AZT was good in 2 cases of purulent meningitis, excellent in 1 case of septicemia, excellent in 5 cases of urinary tract infection, excellent in 1 case and good in 3 cases out of 4 cases of gastroenteritis, excellent in 4 cases and poor in 2 cases out of 6 cases of pneumonia and bronchitis, excellent in 2 cases and good in 1 case out of 3 cases of tonsillitis. No side effects and no abnormal laboratory findings were observed except 1 case of mild diarrhea out of 21 cases.

The data presented indicate that the disturbing upward trend in infant mortality in North Carolina has been arrested and possibly reversed during the 1959 through 1963 period. Information obtained from death certificates indicates that infections accounted for slightly more than half (52.4%) of the postneonatal deaths occurring in the study periods. The most common type of infection was influenza and pneumonia, followed by gastroenteritis and colitis, infective and parasitic disease, meningitis, and acute respiratory infections, in that order of frequency. Infections were responsible for a greater percentage of the postneonatal deaths among nonwhite (58.5%) than amon white infants (40.7%). the postneonatal death rate from infections was 13.4 for nonwhite infants and 2.2 for white infants. The next most common cause of postneonatal mortality -- congenital malformations -- was relatively more important in the white race, being responsible for approximately 25% of white deaths and only 6% of nonwhite deaths. I11 defined and unknown causes ranked 3rd in importance, with postneonatal death rates of 3.0 for nonwhite and .4 for white infants. Accidents, wich ranked 4th, were responsible for approximately 10% of the postneonatal deaths in each race. In both races, the risk of postneonatal death was greater in infants born to younger mothers, partiuclarly those under age 20. For the infants of mothers under age 15, the postneonatal death rate was 3 times as high as for those of 20-24 year old mothers. Beginning with age 20, the risk of postneonatal mortality decreases gradually as maternal age increases up to 35 years, when it begins to rise again in the white race. In nonwhite races, the decline continoues to age 40. Infants born to young mothers of nonwhite races suffer relatively higher postneonatal mortality than do their white counterparts. The postneonatal mortality rate is lowest for 1st born infants of both races. Among nonwhites, it is highest for the 2nd born; in the white race, it rises with each successive birth, with the exception of the 5th. Postneonatal mortality among very small white infants (those weighing less thatn 1500 gm at birth) was some 7 times that of infants weighing more than 2500 gm; it was even higher in nonwhite races being nearly 2 1/2 times that of the white group and appoproximately 4 times higher than the rate for nonwhite infants weighing more than 2500 gm at birth. The risk of postneonatal death for nonwhite infants born illegitimately was 1 1/2 times as great for those born in wedlock. Among white infants, the risk was almost twice as great for those born out of wedlock.

During a one-year period, 315 of 5,397 children admitted to the general pediatric wards of a hospital had bacteremia. The commonest causative organisms were Streptococcus pneumoniae, Salmonella enteritidis, Hemophilus influenzae, and Escherichia coli. Most episodes of bacteremia were associated with gastroenteritis, pneumonia, or meningitis. Seventy-eight episodes occurred in children with severe protein-energy malnutrition, and 46 episodes were hospital acquired. The overall case fatality rate was 23.2%, being highest in children with severe malnutrition and in those with other underlying conditions. The high proportion of bacteremias due to S pneumoniae and S enteritidis possibly reflects infections occurring in a lower socioeconomic group living in a temperate climate in crowded conditions. The most appropriate antimicrobial therapy for children who have suspected bacteremia in association with gastroenteritis or severe malnutrition is a combination of ampicillin sodium and gentamicin sulfate.
