Simian agent 8 (SA8) is an alphaherpesvirus that was first reported as a spontaneous natural infection in a captive baboon colony in 1988. It was first isolated from an African vervet monkey in 1958 and was classified as a simian agent. Simian agent 8 was later isolated from a baboon rectal swab specimen in 1969 and from an oral lesion in a vervet monkey in 1972. Restriction endonuclease analysis was used to identify the virus as SA8. In a 1-year period, 70 baboons housed in two outside 6-acre breeding corrals developed lesions principally on the genitalia and oral cavity. The incidence was the same for males and females, with recurrence rate, severity of the lesions, and duration for the lesions to resolve being greater in the female baboons. Lesions involving the mouth, tongue, and lips were most commonly observed in the juvenile population. The lesions tended to start as small multiple papules or vesicles, which advanced to large pustular or ulcerative areas. Using an every-other-day treatment regimen consisting of Nolvasan cleaning and procaine penicillin G injections, it took an average of 14 to 21 days for the lesions to resolve totally. Thirty-seven percent of the baboons with herpetic lesions experienced another episode of SA8 infection, usually within 1 year of development of the primary lesion. Several complications have been documented to be associated with SA8 infections. Partial or total vaginal obstruction is most common, leading to impaired breeding performance and pyelonephritis. A vaginal corrective surgical procedure has been developed to allow these females to return to productive breeding status within the colony. Penile urethral obstruction, also causing pyelonephritis, was observed in the male baboons. A case of sciatic neuritis was reported in a baboon that presented with self mutilation of the foot; viral isolation revealed the etiologic agent to be SA8. Four female baboons with chronic SA8 infections went on to develop perineal neoplasms. This is an economically important disease entity in captive baboons because it causes severe morbidity, decreased reproductive performance, and ultimately death in 1% of the baboon colony each year. The baboon is a promising animal model in which to study genital herpes as it relates to disease in human beings.

The results of the bacteriological investigation of the secretion from the trachea, large bronchi and fauces of 36 newborns (including 27 preterms) with severe pneumonia were analyzed. 20 of them were born of women with complicating somatic, obstetric and gynecologic histories: candidiasis, herpes genitalis, chronic endometritis, adnexitis or chronic pyelonephritis that could be the risk of the fetus intranatal infection. During the acute period of pneumonia in the newborns within the first 4-8 days of life mainly Pseudomonas aeruginosa was isolated (51.3 per cent), Staphylococcus epidermidis, S. haemolyticus and Enterococcus faecalis were less frequent (18.9, 8.1 and 5.4 per cent, respectively). Klebsiella pneumoniae, Streptococcus anhaemolyticus and other organisms were extremely rare. On the whole the gramnegative microflora predominated. The study of the antibiotic susceptibility showed that the majority of the P. aeruginosa isolates were susceptible to amikacin and polymyxin B, the isolates susceptible to ceftazidime were less frequent, 20-25 per cent of the isolates were susceptible to ciprofloxacin, cefoperazone and imipenem and practically no isolates were susceptible to gentamicin. The S.epidermidis isolates were susceptible to rifampicin and vancomycin and in rare cases to fusidin and amikacin and resistant to oxacillin. When the treatment course was more than 15 days, the isolates proved to be susceptible to 1/3 of the presently available antibiotics. Because of the host low protective forces, peculiarities of the infection pathways and high frequency of the resistant strains it is valid to include netilmicin, imipenem, cefoperazone and ceftriaxone to the complex therapy of the newborns along with the substitution immunotherapy.

Recently the 'Kwaliteitsinstituut voor de gezondheidszorg CBO' (Dutch Institute++ for Health Care Improvement) published revised guidelines on urinary tract infections. In children less than one year old clinical signs of urinary tract infection are non-specific and the diagnosis should be ruled out by laboratory investigations: a nitrite test, followed by inspection of the urinary sediment for leucocytes and bacteria if the test is negative. If one of the investigations is positive an urinary culture is made and antimicrobial therapy is started as for pyelonephritis. The child should be referred to a paediatrician to examine the urinary tract for anatomical abnormalities with a view to possible preventive measures regarding renal function loss. Boys older than one year with urinary tract infections should be managed in the same way as younger children. In older girls examination of the urinary tract is indicated after recurrent infection. In adult women with complaints of urinary tract infection causes like vaginitis, pyelonephritis and genital herpes should be excluded. Urine is examined (nitrite test, if negative followed by urinary sediment) to confirm the diagnosis. A urine culture is not indicated. First-choice treatment for uncomplicated infection is trimethoprim or nitrofurantoin. Persistent infection may be treated blind with a second antimicrobial drug. Recurrent infection can be prevented by changing behaviour, antimicrobial prophylaxis or oestrogen cream in postmenopausal women. If a man with micturition complaints also suffers from pain in the perineum, the lower back or the lower abdomen or during ejaculation, a distinction should be made between bacterial prostatitis, non-bacterial prostatitis and prostatodynia. Uncomplicated urinary infections can be treated with trimethoprim or nitrofurantoin. Urinary catheters are a risk for infection and their use should be restricted in number and duration. Catheter care should follow the guidelines of the Workgroup Infection Prevention. Urinary cultures should only be made in the presence of signs of infection if there is an indication for antimicrobial therapy.
