Trichomonas vaginalis organisms were mixed with suspensions of Neisseria gonorrhoeae, Mycoplasma hominis or Chlamydia trachomatis to allow ingestion of these micro-organisms by the trichomonads. Culture studies indicated that gonococci and mycoplasmas were ingested and that the number of intracellular viable organisms decreased rapidly, most gonococci being killed within six hours and all mycoplasmas within three hours. Electron microscopy revealed phagocytic uptake and destruction of these two micro-organisms within the trichomonads, gonococcal degradation being associated with lysosomal enzyme activity. There was no evidence from cultural or electron microscopy studies that C trachomatis organisms persisted in mixed culture with T vaginalis.

Epidemiologic factors important in acute pelvic inflammatory disease (PID) are the pathogenic organisms Neisseria gonorrhoeae and Chlamydia trachomatis, less pathogenic mycoplasma, and endogenous aerobic and anaerobic bacteria. Other risk factors for PID include the number of sexual partners, previous PID, previous gonorrhea, and male gonorrhea. The patient's age, IUD use, and social factors may be dependent variables for the development of PID. The diagnosis is often difficult to establish; practical diagnostic methods include a careful history and physical examination, laboratory tests (particularly a cervical Gram stain), culdocentesis, and examination of the male. Laparoscopy should be used when the diagnosis is unclear.

The etiology of acute pelvic inflammatory disease is multifactorial, and the pattern of organisms most frequently causing the condition fluctuates. For example, tuberculous salpingitis has gradually become a rarity in many areas, and cases of nongonococcal salpingitis have started to outnumber those of gonococcal salpingitis. Chlamydia trachomatis now causes more cases than Neisseria gonorrhoeae in many regions. Mycoplasma hominis is another (often overlooked) etiologic agent infection in the upper genital tract of women. Pelvic inflammatory disease due to anaerobic microorganisms seems to occur more frequently in some areas (i.e., the United States) than in others (i.e., Europe).

Paired sera from 60 consecutive patients with acute salpingitis, confirmed by laparoscopy, were examined for serum antibodies to Chlamydia trachomatis, Mycoplasma hominis, and Neisseria gonorrhoeae. By a microimmunofluorescence (MIF) test IgM or IgG antibodies to C trachomatis or both were present in sera from 80% of the patients' by indirect haemagglutination (IHA) tests antibodies to M hominis and N gonorrhoeae pilar antigens were present in 40% and 18% respectively. In a control group of 50 pregnant women antibodies to the same three organisms occurred in 8%, 8%, and 6%. Evidence of current chlamydial infection was found in 35 (58%) and of current gonococcal infection in five (8%) of the 60 patients by culture or serological tests or both. The results of chlamydial antibody tests correlated with the severity of the tubal inflammation (as shown by laparoscopy) and the duration of the lower abdominal pain before attendance. The predictive values of a positive and a negative MIF test result were 44% and 83% respectively and of the IHA gonococcal antibody test 36% and 100% respectively. Significant rises in titre of antibodies to M hominis were found in 12% of patients. A four-fold or greater rise in titre indicated probable double infections with chlamydia and mycoplasmas in 7% of patients. Thus, at present gonococcal salpingitis appears to form only a small proportion of all cases of salpingitis in southern Sweden, and in patients with nongonococcal salpingitis infections with C trachomatis and M hominis commonly occur.

A modified formulation of New York City medium was comparatively evaluated with Martin-Lewis medium for the recovery of Neisseria gonorrhoeae from clinical specimens. A total of 240 strains of gonococci were recovered from 1,250 specimens collected from walk-in patients attending a sexually transmitted disease clinic. N. gonorrhoeae was cultivated on both of these media from 182 clinical specimens with an additional 58 gonococcal strains isolated on either of the media. Of these discrepant gonococcal isolates, 27 strains were recovered on only modified New York City medium, whereas the remaining 31 strains were recovered on only Martin-Lewis agar. The differences in these isolation rates were not statistically significant. The overall results showed that modified New York City and Martin-Lewis media were comparable in their ability to grow gonococci from clinical material. Since modified New York City medium is capable of supporting the growth of N. gonorrhoeae, Mycoplasma pneumoniae, and urogenital mycoplasmas and inhibiting the growth of commensal microorganisms, it is possible that it may have considerable application as a multifunctional plating medium within the clinical laboratory.

At present there are no reliable statistics on the relative prevalences of sexually transmitted diseases (STDs) in Spain. In a report of the first three years' experience in an STD diagnostic centre between 1977 and 1979 a total of 879 patients (534 men adn 345 women) were seen. They mainly consisted of university students and the mean age was 22 years in 1977 and 23 years in the following two years. All the patients were examined for syphilis and all women for gonorrhoea and trichomoniasis. Investigations for Chlamydia trachomatis, Mycoplasma hominis, Ureaplasma urealyticum, Candida albicans, and Herpesvirus hominis infections were carried out according to the presenting symptoms. Non-specific genital infections occurred most commonly (25.7%); chlamydia were isolated from 30% of the patients with non-gonococcal urethritis (NGU). The second commonest infection was candidosis (13.5%). Gonorrhoea, which was found in 10.6% of the patients, was diagnosed more frequently in men (13.5%) than in women (6%). No strains of beta-lactamase-producing Neisseria gonorrhoeae were detected and all were sensitive to penicillin. Syphilis was diagnosed in 4.4% of patients (2% women and 5% men). Condylomata acuminata were diagnosed in 2.8% of patients and more frequently in men (4%). Herpes genitalis and venereophobia were uncommon (1.9% and 1.2% respectively) and were diagnosed only in men.

Conservative treatment of acute salpingitis should be the rule, surgery the exception. Neisseria gonorrhoeae, Chlamydia trachomatis, and Mycoplasma hominis, are common etiological agents in pelvic inflammatory disease, particularly in women below the age of 25 years. In women above that age as well as in those with two or more episodes of acute salpingitis, there is a higher proportion of tubal infections caused by aerobic and facultatively anaerobic bacteria. Apart from some resistant strains, tetracycline generally has an effect on all three of the above-mentioned agents of sexually transmitted diseases (STD). We recommend that this drug be chosen if the results of etiological studies are not known when therapy is started. If there is reason to believe that anaerobic bacteria may be involved, tetracycline may be combined with nitroimidazole. The short-term effects of various antibiotic drugs in acute salpingitis suggest that women with gonococcal salpingitis will respond sooner than will women with non-gonococcal salpingitis, regardless of which antibiotic regimen is given. The long-term effect of several different antibiotics on the post-salpingitic fertility does not differ. Glucocorticosteroids do not seem to positively influence the prognosis for fertility. To help prevent salpingitis, it is important to advise patients on appropriate contraceptive usage and to examine and treat both patients and consorts for STD.

Chlamydia trachomatis was recovered from the fallopian tubes of ten women with acute salpingitis. The median age of the patients was 19 years. The duration of pelvic pain before consulting a physician ranged from three to 27 days (median, seven days). Half of the patients complained of irregular bleeding, and nine reported increased vaginal discharge. One patient had a rectal temperature of greater than 38 C, and one had an erythrocyte sedimentation rate of less than 15 mm/hr. At laparoscopy, mild inflammatory changes were seen in the tubes of three patients, five had moderately severe inflammation, and two had pelvic peritonitis. C. trachomatis could not be isolated from the cervix of two patients. Paired sera were available from eight patients, six of whom had a significant rise in titer of IgG antibodies to C. trachomatis. Two women had IgM antibodies. Two other women, who harbored Neisseria gonorrhoeae in the cervix, had antibodies to gonococcal pili; one had a significant decrease in titer. This latter patient was one of the patients with a stationary titer of antibodies to C trachomatis. One patient had a stationary titer of antibodies to Mycoplasma hominis. In general, chlamydial salpingitis seems to have relatively benign symptoms. Neither the failure to isolate C. trachomatis from the cervix nor a stationary titer of antibodies to the organism precludes a chlamydial etiology of acute salpingitis.

Most patients who seek medical attention for sore throat are concerned about streptococcal tonsillopharyngitis, but fewer than 10% of adults and 30% of children actually have a streptococcal infection. Group A beta-hemolytic streptococci (GAS) are most often responsible for bacterial tonsillopharyngitis, although Neisseria gonorrhea, Arcanobacterium haemolyticum (formerly Corynebacterium haemolyticum), Chlamydia pneumoniae (TWAR agent), and Mycoplasma pneumoniae have also been suggested as possible, infrequent, sporadic pathogens. Viruses or idiopathic causes account for the remainder of sore throat complaints. Reliance on clinical impression to diagnose GAS tonsillopharyngitis is problematic; an overestimation of 80% to 95% by experienced clinicians typically occurs for adult patients. Overtreatment promotes bacterial resistance, disturbs natural microbial ecology, and may produce unnecessary side effects. Existing data suggest that rapid GAS antigen testing as an aid to clinical diagnosis can be very useful. When used appropriately, it is sensitive (79% to 88%) in detecting GAS-infected patients and is specific (90% to 96%) and cost-effective. Penicillin has been the treatment of choice for GAS tonsillopharyngitis since the 1950s; 10 days of treatment are necessary for bacterial eradication. A single IM injection of benzathine penicillin is effective and obviates compliance issues. Until the early 1970s, the bacteriologic failure rate for the treatment of GAS tonsillopharyngitis ranged from 2% to 10% and was attributed to chronic GAS carriers. Since the late 1970s, the penicillin failure rate has frequently exceeded 20% in published reports. Explanations for recurrent GAS tonsillopharyngitis include poor patient compliance; reacquisition from a family member or peer, copathogenic colonization by Staphylococcus aureus, Haemophilus influenzae, Moraxella catarrhalis, anaerobes that inactivate penicillin with beta-lactamase, or all these organisms; suppression of natural immune response by too-early administration of antibiotics; GAS tolerance to penicillin; antibiotic eradication of normal pharyngeal flora that normally act as natural host defenses; and establishment of a true carrier state. When therapy fails, milder symptoms may occur during the relapse. Several antimicrobials have demonstrated superior efficacy compared with penicillin in eradicating GAS and are administered less frequently to enhance patient compliance. In previously untreated GAS throat infections, cephalosporins produce a 5% to 22% higher bacteriologic cure rate; after a penicillin treatment failure, these differences are greater. Amoxicillin/clavulanate and the extended-spectrum macrolides clarithromycin and azithromycin may also produce enhanced bacteriologic eradication in comparison to penicillin.(ABSTRACT TRUNCATED AT 400 WORDS)

In an ongoing study we evaluated 71 males and 32 females attending our sexually transmitted diseases (STD) clinic. Intraurethral or endocervical swab specimens were cultured for Neisseria gonorrhea (NG), Ureaplasma urealyticum (UU), Mycoplasma homines (MH), Herpes simplex virus (HSV) and Chlamydia trachomatis (CT), using an ELISA technique and the polymerase chain reaction (PCR). HIV antigen, hepatitis B (HBV) and Treponema pallidum (TP) seropositivity were tested by ELISA. Mean age was 33.4 and range 15-72 years. 83 patients (81%) used condoms only rarely, 35 (35%) had multiple sexual partners and 83 (81%) were treated empirically prior to evaluation. Dysuria and urethral discharge were found in 47 (45.6%), of whom 34 (33%) were males; the majority of females were asymptomatic. A specific etiology for STD was found in 53 patients (51.4%) and 1/3 had more than 1 pathogen. CT, UU, MH, HSV, NG and TV were found in 27, 24, 5, 3, 2 and 1, respectively. 8 patients were seropositive for HBV and 1 for TP; all were seronegative for HIV. CT was the most prevalent pathogen found. All patients with STD symptoms should be screened for all sexually transmitted pathogens, since many of them have more than 1 pathogen. STD clinics in Israel should be developed in conjunction with microbiology laboratories for better management of STD in the community.
