Among the opportunistic infections observed during infection with human immunodeficiency virus, recurrent non-typhoid salmonella bacteriemia has not been widely documented in Black Africa. This retrospective study identified 5 cases of non-typhoid salmonellosis in a series of 27 seropositive patients, i.e. 18.5%, hospitalized over a two-year period in an internal medicine department in Senegal. All 27 patients presented general or digestive manifestations and were in the stage of full-blown AIDS. The diagnosis was salmonella septicemia in 60% of cases. The incidence of salmonella is higher in immunocompromised patients than in healthy subjects, particularly in Africa. These infections frequently lead to bacteriemia, have a strong tendency to recur, and are highly indicative of immunodeficiency. Salmonellosis which is curable should be suspected in seropositive African patients presenting general and/or digestive manifestations.

Seventeen complicated outbreaks of infectious coryza in layer, broiler-breeder, and broiler flocks were studied. In the layer flock outbreaks, drops in egg production of up to 35% were seen. In the broiler flocks and several of the layer flocks, losses due to persistent mortality and/or culling varied between 2 and 5%. Signs of infectious coryza in both layers and broiler-breeders were typical; in broilers, however, swollen head-like syndrome was seen. Except in one flock, no viral diseases were clinically or serologically detected. Excluding broiler-breeders, birds from most other flocks were serologically positive for Mycoplasma gallisepticum, and some were also positive for M. synoviae. Haemophilus paragallinarum was isolated from all of the outbreaks, but only as a pure culture in three outbreaks. Isolation of H. paragallinarum from sites such as liver, kidney, and particularly tarsal arthritis and ocular globes appears to be reported for the first time. Serovar A was isolated in eight outbreaks, serovar B in six, serovar C in one, and untypable serovars in two. The severity of these infectious coryza outbreaks may have been increased by concurrent salmonellosis, pasteurellosis, and mycoplasmosis, although under certain conditions H. paragallinarum is able to cause septicemia. Ten of the outbreaks occurred in birds vaccinated against infectious coryza; this may be due to the use of vaccines that do not provide protection against the types of H. paragallinarum that affect poultry in the region.

Relapses of enteric fever induced by Schistosoma intercalatum have been observed to occur in central Africa. In Libreville, Gabon, 70 children (ages, 2.1-15.9 years) who were seronegative for human immunodeficiency virus and were hospitalized for septicemic salmonellosis underwent rectal biopsy for diagnosis of S. intercalatum infection. A nontyphoidal Salmonella species was isolated from 53 of the 70 patients: Salmonella typhimurium in 14 cases; Salmonella enteritidis in 7 cases; Salmonella galiema in 4 cases; Salmonella arizonae in 3 cases; and other species in 25 cases. Schistosomal eggs were present in the rectal mucosa of 48 (90.6%) of these 53 patients, in 11 (64.7%) of 17 patients with septicemia due to Salmonella typhi or Salmonella paratyphi, and in 21 (38.2%; P < .001) of 55 controls. Clinical symptoms were not different among patients coinfected with S. intercalatum and nontyphoidal Salmonella vs. those with enteric fever. Treatment with antibiotics induced apyrexia only after administration of antiparasitic therapy in 30 patients. These data strongly suggest interactions between S. intercalatum and Salmonella in infected children with clinically severe nontyphoidal salmonellal septicemia.

The epidemiology of salmonellosis has undergone a change during the last 2 years. An increase in the number of cases of enteritis and sepsis caused by Salmonella enteritidis has been observed. We report on the case of a 65-year-old woman with mitral valve endocarditis due to Salmonella enteritidis. The infective endocarditis occurred without prior episodes of gastroenteritis. After having undergone prosthetic valve replacement and antibiotic therapy with ciprofloxacin, the patient recovered completely.

From July 1986 through June 1990, 33,199 sera from various risk groups were collected in Veterans General Hospital-Taipei for detection of antibody against human immunodeficiency virus, type 1 (HIV-1). Sixty-five samples were proved positive by Western blot analysis. Among individual high risk groups, hemophiliacs had the highest positive rate of 20/60 (29.41%), followed by homosexual/bisexual males (41/1,264, 3.24%). The overall positive rate was 65/33,199 (0.19%). Ten cases were recognized as acquired immunodeficiency syndrome (AIDS), 1 case had AIDS-related complex (ARC) and 4 case had other apparently symptomatic infections. Among these 15 cases, 7 expired, 1 lost of follow-up and 7 surviving cases are being treated with zidovudine (AZT). Most of symptomatic HIV-1 antibody positive cases had abnormal T4/T8 ratio of 0.39 +/- 0.54 as compared with the asymptomatic HIV-1 carriers at a ratio of 0.81 +/- 0.69. The opportunistic infections included Pneumocystis carinii pneumonia (PCP) in 6 case, disseminated cytomegalovirus infection in 6 cases, herpes zoster virus infection in 3 case, candidiasis in 4 cases, syphilis in 3 cases, pulmonary tuberculosis in 2 cases, and others with cryptococcosis, salmonellosis, Mycobacterium avium-intracellulare infection, gonorrhea, Staphylococcus aureus endocarditis and bacterial sepsis, etc. The natural history of HIV-1 infection to AIDS involved acute and persistent multiple infections. Although prevalence of HIV-1 infection was low in Taiwan, nationwide surveillance of HIV-1 infection in various risk groups is still needed.

Clinical presentation of generalized salmonellosis is reviewed. Typhus-like form occurred in 28, septic form in 15 cases (0.5 and 0.3% of all the patients observed, respectively). Salmonellosis sepsis is hard to detect in view of multiple visceral lesions, long-term fever and severe intoxication.

Two stable rough mutants of Salmonella spp. were studied as live peroral vaccines. The SF1591 mutant of S. typhimurium (Ra chemotype) protected germ-free piglets against subsequent infection with virulent smooth S. typhimurium LT2, whereas a deep-rough mutant of S. minnesota mR595 (Re chemotype) did not. We investigated cytokine and leukocyte profiles in the ilea of gnotobiotic piglets colonized for 1 week either with rough mutants alone or with rough mutants followed by S. typhimurium LT2. The ileal mucosae of piglets associated with strain SF1591 alone were not inflamed. Villi contained activated macrophages, and enterocytes expressed transforming growth factor beta (TGF-beta). Subsequent infection of piglets with S. typhimurium LT2 resulted in immigration of alphabeta T cells and immunoglobulin A (IgA) response. In contrast, the ileal mucosae of piglets associated with strain mR595 alone expressed heat shock proteins and inflammatory cytokines but not TGF-beta. Acellular villi contained numerous gammadelta T cells but no alphabeta T cells. After subsequent challenge with the LT2 strain, most piglets died of sepsis. Intestinal mucosae contained IgG but no IgA. These findings suggest the importance of cytokine signals in the regulation of intestinal responses against Salmonella infection.

All food animals are susceptible to infection with Salmonella, a genus of gram negative, nonspore-forming, usually motile, facultative anaerobic bacilli belonging to the family Enterobacteriaceae. Salmonella are differentiated into over 2200 serologically distinct types (serotypes) based on differences in somatic, flagellar, and capsular antigens. Infection with Salmonella may or may not lead to a sometimes fatal salmonellosis, a disease that can remain localized in the gastrointestinal tract as gastro-enteritis, or become generalized as a septicemia and affect several organ systems. Infected food animals that do not develop salmonellosis, and those that recover from the disease, become carriers of Salmonella and serve as sources of infection to humans and other animals. Apart from being a source of Salmonella food poisoning for humans, Salmonella-contaminated food animal carcasses are also a concern because they are a source of antibiotic-resistant Salmonella.

LPS-binding protein (LBP) recognizes bacterial LPS and transfers it to CD14, thereby enhancing host cell stimulation, eventually resulting in pathogenic states such as septic shock. Recently, LBP also was shown to detoxify LPS by transferring LPS into HDL particles in vitro. Thus, the predominant in vivo function of LBP has remained unclear. To investigate the biological activity of acute phase concentrations of recombinant murine LBP, high concentrations of LBP were investigated in vitro and in vivo. Although addition of low concentrations of LBP to a murine macrophage cell line enhanced LPS-induced TNF-alpha synthesis, acute phase concentrations of LBP blocked this effect in comparison to low-dose LBP. When injected into mice intraperitoneally, LBP inhibited LPS-mediated cytokine release and prevented hepatic failure resulting in a significantly decreased mortality rate in LPS-challenged and D-galactosamine-sensitized mice, as well as in a murine model of bacteremia. These results complement a recent study revealing LBP-deficient mice to be dramatically more susceptible to an intraperitoneal Salmonella infection as compared with normal mice. We conclude that acute phase LBP has a protective effect against LPS and bacterial infection and may represent a physiologic defense mechanism against infection. Despite the limitations of any murine sepsis model, the results shown may imply that LBP could have beneficial effects during gram-negative peritonitis in humans.
