1.  Isolation of Chlamydia trachomatis from endometriums of women with and without symptoms. 
Genitourinary Medicine  1988;64(2):75-77.
Chlamydia trachomatis was isolated from the endometrial cavities of three out of 19 women with positive cervical cultures, who were all symptomless sexual contacts of men with non-gonococcal urethritis (NGU). C trachomatis was recovered from the endometrial cavities of four out of 14 women with pelvic inflammatory disease (PID), three of whom had positive cervical cultures. Although endometrial biopsy is probably not justifiable as a routine procedure, it may be a useful adjunct to endocervical investigations for managing women with PID.

2.  Sulfamethazine residues in uncooked edible tissues of port following recommended oral administration and withdrawal. 
Commercial feed rations containing sulfamethazine at the level of 110 ppm were fed for a period of 65 days to market pigs in a study simulating normal farm practices. The levels of sulfamethazine at the end of medication were in excess of 10 ppm in liver and kidney and up to 2.6 ppm in muscle tissues. Concentrations of sulfamethazine in tissues from pigs after withdrawal of medicated feed depleted to 0.1 ppm within nine days. The rate of depletion was similar for all tissues. It was observed that storage of tissue samples at freezer temperature (-20 degrees C) for 30 days further reduces sulfamethazine levels by 3 to 20% of their original value.

3.  Free Flying Sparrows as Carriers of Salmonellosis 
The Canadian Veterinary Journal  1979;20(5):143-144.
Salmonella typhimurium was isolated from nine of 60 wild sparrows trapped in the Guelph area. While this organism was isolated from birds trapped at several different locations, the highest prevalence was in sparrows trapped in close proximity to an animal clinic. The significance of these findings in relation to human and animal salmonellosis is discussed.

5.  Antimicrobial susceptibility of Salmonella isolates from the broiler chicken industry in Ontario. 
Antibacterial drug resistance among 219 salmonella isolates recovered during 1974 from poultry and poultry environments at the various production stages of broiler chickens in three integrated Ontario companies are recorded. All isolates were susceptible to ampicillin, trimethroprim-sulfamethoxazole complex, furazolidone, cephaloridine and amoxicillin. A relative increase in resistance to tetracycline and streptomycin with an accompanying decrease in resistance to triple sulfa compound was recorded when compared to a previous investigation of avian salmonella isolates in Ontario. The percentage and patterns of antimicrobial resistance were comparable at the various stages of production. Resistance to tetracycline and streptomycin was the most common pattern found among both Salmonella typhimurium and other serotypes. A notably high prevalence of resistance was found among Salmonella enteritidis isolates including some isolates with R factors for chloramphenicol resistance. This latter finding is of particular concern because of the high prevalence of this serotype in poultry and in human salmonellosis.

6.  The recovery of Mycoplasmas from the genital tracts of bulls in artificial breeding units in Ontarïo. 
One hundred and thirty-two penial-preputial swabbings, 140 raw and 42 processed semen samples were cultured for mycoplasmas. Mycoplasma or acholeplasma were recovered from 87, 32 and one respectively, while ureaplasmas were recovered from 46, 34 and six respectively.

7.  In vitro antimicrobial sensitivity of Mycoplasmas isolated from the bovine genital tract. 
The in vitro antimicrobial sensitivity of 14 mycoplasma and 13 ureaplasma strains isolated from the genital tracts of bulls was examined. It was found that at relatively low concentrations, tetracycline, declomycin and tylosin were lethal to both types of organisms. Lincospectin, berenil, streptomycin and erythromycin were lethal to mycoplasmas but were only inhibitory to the ureaplasma strains at the same concentrations. Polymyxin B and novobiocin were ineffective at the levels tested.

18.  A Survey of Toxoplasmosis Among Mentally Retarded Children 
Canadian Medical Association Journal  1965;92(19):1026-1028.
To determine what role, if any, toxoplasmosis plays in the mental retardation of children, sera from 345 mentally retarded children were tested for the presence of antibodies to Toxoplasma gondii. The serological tests employed were the complement-fixation, the Sabin-Feldman dye test and the immunofluorescence test. The donors were also skin-tested with toxoplasmin.
Of 345 mentally retarded donors nine gave a positive skin reaction, 15 possessed complement-fixing antibodies, 21 had immunofluorescent antibodies and 45 had dye test antibodies to T. gondii.
The incidence of antibodies to T. gondii in the mentally retarded group was approximately the same as in the normal control group of the same age, and less than in the group suspected of having toxoplasmosis. It is concluded that in the children in this study toxoplasmosis played little or no role as a predisposing factor in the occurrence of congenital mental deficiency.
