JOURNAL FREE ACCESSDuring quarantine inspection, fever and enlarged submandibular lymph nodes were observed in three out of nine quarter horses imported from the USA. Because of negative results in bacterial examinations during the quarantine period, these horses were released. At the riding club that was their destination, however, Streptococcus equi subsp. equi was isolated from three of them. Then strangles spread to other horses in the riding club. Nasal swabs were obtained from all horses at the club weekly until the disease subsided 22 weeks later. S. equi was isolated from 25 of 58 horses (43.1%). The isolates formed mucoidal colonies, and their colony type and SeM genotype differed from those of strains previously isolated in Japan. A decrease in the titer of the serum antibody against S. equi was observed in four of the nine imported horses. It was concluded that the herd infection was caused by the imported carrier horses and spread throughout the riding club.View full abstractDownload PDF (1805K) -

JOURNAL FREE ACCESSThe oocysticidal effects on Cryptosporidium muris oocysts of two commercial disinfectants containing orthodichlorobenzene were examined. Oocysts were treated with the disinfectants diluted to 100, 200 and 400 times for 30 minutes; and 1.5×06 oocysts were administered to ICR mice. After inoculation, the sugar-floating method was used to examine oocysts in feces. No oocysts were detected in feces from mice that had been inoculated with oocysts treated with the two disinfectants.View full abstractDownload PDF (712K) -

JOURNAL FREE ACCESSUsing three cases of clinical Staphylococcal mastitis and two clinically normal cases infected with staphylococci, we investigated correlation between Staphylococcal enterotoxin-C (SEC) and Toxic-shock syndrome toxin-1 (TSST-1) and correlation between specific antibody titers against these toxins in mammary-gland secretions (MGS) and the onset of mastitis. In the cases of clinical mastitis, concentrations of SEC in MGS peaked during the period immediately before onset and onset itself. Somatic cell counts increased after SEC concentration reached a maximum. No SEC was detected in MGS during the lactating period in clinically normal cases. Immediately after parturition, in clinically normal cases, concentration of SEC in MGS was less than in the same udder after the onset of clinical mastitis. TSST-1 concentrations were at the same level in both mastitic and normal cases. In all cases, titers of specific antibodies against TSST-1 in MGS were higher than those against SEC. These results suggest that increased SEC in MGS was an important pathogenic factor in the three cases of clinical mastitis.View full abstractDownload PDF (795K) -

JOURNAL FREE ACCESSNeurological examinations and computed tomography were performed using 31 hydrocephalic dogs to investigate morphological changes in the ventricles. In the animals, the ratio of ventricle volume to brain volume increased significantly compared with that in control dogs. No relations between clinical signs and ventricular morphological changes were observed in the hydrocephalic dogs.View full abstractDownload PDF (1466K) -

JOURNAL FREE ACCESSUnaltered or modified forceps were used in external coaptation of the injured beaks of four Oriental White Storks (Ciconia boyciana). In three cases, forceps were used to compensate for damage to the lower beak. In one case, they were used on both upper and lower beak. The forceps were fixed in place with elastic bandages and served as prostheses for defective beaks. The birds foraged normally and soon recovered from their injuries. The method is simple, and the forceps remain firmly fixed in place. For this reason they promote fast and orderly recovery of beak function.View full abstractDownload PDF (1713K) -

JOURNAL FREE ACCESSObligate, or facultative, anaerobes were isolated from purulent effusion samples taken from six cases of cat pyothorax. On the basis of the susceptibility of these organisms, we used suitable antibiotics and lavage fluids to treat the cats successfully. Microorganisms isolated from pleural-fluid samples were Bacteroides, Fusobacterium, Prevotella, Peptostreptococcus, Eubacterium, Porphyromonas, Black-pigmented GNR group, and Pasteurella, which are frequently isolated from oral microbial flora and subcutaneous abscesses.View full abstractDownload PDF (1505K) -

JOURNAL FREE ACCESSBetween May 1999 and March 2001, a total of 166 raw meat specimens collected from retail markets in Saitama Prefecture was examined for the presence of Salmonella and Listeria sp. Salmonella was isolated from 9.5% of domestic chicken specimens and 13.6% of imported chicken specimens. According to the most-probablenumber (MPN) method, numbers of contaminating Salmonella cells were less than 10 cfu/g. Main Salmonella serotypes were S. Infantis for domestic chicken and S. Enteritidis for imported chicken. Listeria sp. were isolated from all the kinds of meat examined. Isolation rates among domestic meats were 22.7% for beef, 40.0% for pork, and 42.9% for chicken. Rates among imported meats were 34.5% for beef, 30.0% for pork, and 64.4% for chicken. According to the MPN method, contaminating cell numbers were less than 10 cfu/g for all kinds of domestic meat but more than 10 cfu/g for all kinds of imported meat. Some specimens of both imported pork and imported chicken showed more than 100 cfu/g. L. monocytogenes were isolated from all kinds of meat. The most prevalent serotype was 1/2a, accounting for 38.2% of all isolates of the organism.View full abstractDownload PDF (629K) -
