In 1983, the bovine-specific Salmonella Dublin was demonstrated in man in Denmark. The organism is frequently isolated from blood but rarely causes gastroenteritis. The frequency of infection following hip replacement is less than 2% with Staphylococcus aureus as the commonest agent while Gram-negative rods are rarer but are considered to be more serious. Infection around a hip replacement frequently implies that the prosthesis must be removed. A case in which a hip replacement was infected with Salmonella Dublin is described here. The patient had looked after infected calves until operation and it is presumed that the prosthesis was infected haematogenically, either primarily or later. The infection was controlled surgically without removal of the prosthesis which was stable. Even although the condition is satisfactory six months after revision, the long-term prognosis is poor.

Interferon (IFN) treatment increased the level of 2',5'-oligoadenylate (2-5A) synthetase and inhibited replication of transmissible gastroenteritis virus (TGEV) in cultured swine testicular cells. Despite a minimal increase in TGEV titer in IFN-treated swine testicular cells, there was rapid cellular destruction. IFN-treated swine testicular cells had detectable levels of 2-5A (3.6 nM 6 h post-infection) after infection with 30 pfu TGEV/cell. Infection of neonatal pigs with a virulent strain of TGEV caused a significant increase in serum IFN and enterocyte 2-5A synthetase activity, as compared to control pigs. The level of enterocyte 2-5A synthetase in TGEV-infected pigs was increased 25-fold before viral-induced damage of the intestine consistently was present. 2-5A was not detected in enterocytes of either TGEV-infected or control pigs (less than 0.5 nM). Preparations of enterocytes contained two subpopulations of cells, one of which does not support replication of the virus. The considerable dilution of TGEV-infected cells (villous enterocytes) with uninfected cells (crypt cells) may be responsible for our inability to detect 2-5A in enterocytes from TGEV-infected pigs. These results indicate that the 2-5A system in porcine enterocytes and cultured testicular cells is modulated by TGEV infection and/or interaction with IFN.

To focus attention on the problem of infant mortality in Lebanon, data were compiled on infant mortality from 1978 to 1986 at the American University of Beirut Medical Center. Causes of death are analyzed for 602 males and 398 females. 54.9% deaths occurred at 1 month of age and 77.4% died within the 1st year. Autopsies were performed on .7%. 37.7% of all neonatal deaths were due to neonatal diseases such as hyaline membrane disease, asphyxia neonatorum, immaturity, necrotizing enterocolitis, hemorrhage, hemolysis, meconium aspiration, and kernicterus. Better prenatal care would reduce this group, or the administration of corticosteroids to the mother 24-48 hours prior to delivery, as well as rapid resuscitation at birth and prevention of the 5 curses: hypoxemia, hypoglycemia, hypothermia, hypotension, and acidosis. Although unavailable in Lebanon, administration of surfactants through an endotracheal tube would also help. Infections constitute 25.1% of deaths; many are preventable through adequate public health measures and strict personal hygiene, i.e., diseases such as sepsis, pneumonia, meningitis, gastroenteritis, hepatitis, encephalitis, and 1-2 cases of the following: diphtheria, measles, peritonitis, tetanus, tuberculosis, cytomegalis inclusion, herpes, parathyphoid, pertussis, poliomyelitis, and shigellosis. Congenital diseases were 21.6%. In utero diagnosis could prevent some diseases and in utero treatment is possible for hydrocephalus and hydronephrosis. Screening programs postnatally could lead to treatment. 5.9% were malignancies such as leukemia, lymphoma, brain tumors, histocytosis, Wilm's tumor, Ewing sarcoma, and Hodgkin's disease. Early diagnosis is critical if mortality is to be reduced in this group, but medical advances are still needed. 2.9% are miscellaneous diseases such as poisoning, rheumatic diseases, marasmus, Reye's syndrome, nephrosis, rickets, and epilepsy. Most of these diseases are preventable, except for rheumatic inflammation of the heart. Recommended necessary steps to reduce infant mortality are: prenatal care, diagnosis and screening, intrauterine surgery; resuscitation and intensive care centers with modern equipment and trained personnel; national vaccination and screening programs; adequate public health measures and hygiene; parental education; and well-equipped hospitals to serve all regardless of income level.

The Human Parvovirus (HPV) like other Parvovirus is a single strand DNA virus with autonomous replication which measures 23mm. Infection with this virus is followed by a non-specific viral syndrome during the prodrome, leading to viremia, which may be followed by arthropathy and/or different kind of rash including the syndrome called erythema infectiosum. It has also been related to an increase in the number of spontaneous abortion in pregnant women with acute infection; and it is the etiology of the aplastic crisis in patients with hemolytic anemias. Many other Parvovirus serologically different from HPV are present in stools and are responsible for acute infectious non bacterial gastroenteritis in people more than 5 years old.

Cholera gastroenteritis amongst 3595 children under twelve years suffering from acute watery diarrhea was studied for a period of five years (1982-86). V. cholerae 01 could be isolated from 31.7% of total specimens studied. Distribution in different age groups out of total gastroenteritis cases was 7.5% in less than 2 years, 13.1% in 2-5 years and 11.1% in greater than 5-12 years. Out of total cholera cases (1141 isolate) 23.4% occurred in the age group less than 2 yrs., 41.4% in 2-5 yrs. and 35.1% in greater than 5-12 yrs. Infection occurred more often in males in all the age groups. Throughout the study, cholera was observed during summer monsoon season with Ogawa being predominant serotype.

Infections caused by marine vibrios appear to be an increasing problem. Gastroenteritis, soft tissue-infection and septicaemia are the most prevalent manifestations. Different environmental and traditional water quality measurements do not indicate the risk. These infections are confined to the summer and late summer with water temperatures exceeding 20 degrees C. Tourists may be exposed to an extraordinary risk, and infections may not become apparent until they have returned home. High risk groups (e.g. immunocompromized) have a high case-fatality rate. The extremely rapid onset of these infections demand aggressive antibiotic therapy and vigorous debridement at an early stage. Gastrointestinal disorders may necessitate fluid replacement and tetracycline is recommended in severe cases.

This study was conducted to evaluate the efficacy and safety of intravenous sulbactam/ampicillin followed by oral sultamicillin. Parenteral sulbactam/ampicillin was administered for 7 to 14 days to 152 in-patients with moderate to severe infections. All patients were treated with sulbactam/ampicillin, but only 140 patients received oral sultamicillin therapy. Eighty-nine men and 63 women participated in this study. Infections included intraabdominal (42 cases), respiratory tract (52 cases), skin and soft tissue (29 cases), urinary tract (16 cases), and miscellaneous infections (14 cases) that included typhoid fever, gastroenteritis, septicemia, and surgical wound infection. Six (4%) patients reported six study drug-related adverse experiences. Gastrointestinal side effects were most common and included epigastric burning and indigestion. Diarrhea was not reported and no patient discontinued drug therapy because of an adverse event. Laboratory abnormalities were infrequent and clinically insignificant. Overall, 98% of the 114 evaluable patients achieved clinical cure or improvement following treatment with sulbactam/ampicillin and sultamicillin. Cured or improved patients in each diagnostic group were 97% for intraabdominal infections, 100% for respiratory tract infections, 100% for skin and soft tissue infections, 100% for urinary tract infection, and 91% for other types of infections. Only 2 (2%) patients were judged to be treatment failures. Microbiologic efficacy, or eradication, was 86% overall, ranging from 75 to 100%. Persistence of pathogens occurred in 5%, and eradication with development of a superinfection occurred in 4%. Fifty-seven percent (30/50) of the isolates tested were resistant to ampicillin alone whereas only 21% (9/42) were resistant to sulbactam/ampicillin (p = 0.002).(ABSTRACT TRUNCATED AT 250 WORDS)

We reviewed retrospectively the clinical records of patients with non-typhi Salmonella bacteraemia in our hospital from 1979 to 1988. During the study period 45 non-typhi Salmonella bacteraemias were diagnosed in 43 patients. Ten patients were under one year old and 11 were over 60. Seven cases of sepsis presented in patients with AIDS. Only three episodes were nosocomially acquired. In two of three patients the bacteraemia was preceded by an episode of acute gastroenteritis and one third presented without gastroenteritis. Complications and mortality were infrequent in spite of the differing degrees of adequacy of antibiotic treatment which was inappropriate in many cases. We have attempted to assess optimal antibiotic therapy, taking into account the duration and means of administration, in different groups of patients with nontyphi Salmonella bacteraemia.

The development of an enzyme immunoassay (EIA) capable of serotyping human rotavirus (HRV) in faecal extracts has enabled us to retrospectively study the epidemiology of rotavirus infection in Melbourne. Of 552 stored specimens obtained from individuals with rotavirus-associated gastroenteritis between 1975 and 1986, the serotype could be determined in 62%. Infection was most prevalent in two groups, neonates and children aged between 12 and 24 months. In these groups infection was due to different serotypes, type 1 in older children and an untypable virus in infants. Serotype 1 strains were detected in greater numbers than the other serotypes and circulated in each year of the study. Serotype 2 rotaviruses were associated with a large epidemic in 1978, but have been detected only rarely since.

Feline infectious peritonitis (FIP) is caused by one of several strains of feline coronaviruses which are grouped into 2 general types of viruses. Infection of cats with FIP virus results in production of serum antibodies which may be protective in conjunction with cell mediated immunity, may provided no protection at all, or may produce an immune enhancement to subsequent exposure to another FIP virus or a recrudescence of the original infecting virus. Attempts at immunization of cats against FIP with inactivated or live FIP viruses have been generally unsuccessful, and often sensitizing the cat through immune enhancement rather than providing protection. Heterologous live virus vaccines using viruses of the same antigenic cluster (transmissible gastroenteritis of swine, canine coronavirus, and human coronavirus 229E) have failed to provide protection against FIP virus. Further research into the exact mechanism of protection and immune enhancement is needed in order to understand ways of producing an effective and safe vaccine.
