The effect of thiamphenicol on hematopoietic system has to be evaluated. One hundred and fifteen male patients had been given oral 2. 5 gm thiamphenicol for uncomplicated gonococcal infection. ln this study, hemoglobin, WBC, hematocrit, reticulocyte and differential WBC counts were evaluated before, R days, 10 days and 1 month after the treatment. Hemoglobin, WBC, reticulocyte and differential WRC counts did not show any differences between pre and 3 days, l0days and 1 month post-treatment. In jailed cases, WBC count was found to be raiseri pretreatment(7,500 1-1.700, n='30) and 3 days after the treatment(v, 1pp+1,6p0, n=Rp) from normal value (Ii,100.:>1,600 in NMC biochemistry). In cured cases, WBC count was also found to be raised pre-treatment(7,50Q-i- 2,100, n=54) from normal value(6, 1001, 500), but returned to norrna1 3 days (6, 100 ! 1, 500, n = 54) and 10 days after the treatment, no cases showed any significant changes for WBC count(v,ppp-+1,gpp, n=7) from normal value(6,1%)- 1,500). Other side effect of thiamphenicol, such as hematologic toxicity and aplastic anemia had not been observed. Therefore, thiamphenicol 2. 5 gm p.o. is well tolerated and non-toxic treatment.

Actinobacillus (A.) pleuropneumoniae is the causative agent of pleuropneumonia which is one of the most important respiratory diseases in pigs worldwide. A total of 32 A. pleuropneumoniae isolates from diseased pigs during 2008 to 2010 were serotyped by polymerase chain reaction method. The susceptibility of the isolates to 13 antimicrobial agents were determined by disk diffusion test. In all the 32 isolates examined in this study, serotype 5 (16 isolates: 50%), 1 (7 isolates: 21.9%), 2 (5 isolates: 15.6%) and 12 (1 isolate: 3.1%) were found. Of all tested antimicrobial agents, resistance to oxytetracycline was found in 96.9% of isolates, followed by resistance to amikacin (81.2%), neomycin (68.7%), kanamycin (53.1%), penicillin (50.0%), gentamicin (43.7%), florfenicol (25.0%), ampicillin (18.7%), colistin (9.4%), trimethoprim/sulfamethoxazole, ceftiofur (8.3%), amoxicillin/clavulanic acid (3.1%) and enrofloxacin (0%). Oxytetracycline or florfenicol-resistant isolates were examined for the presence of resistance gene. Among the 31 oxytetracycline-resistant isolates, tetB, tetH and tetO genes were detected in 22 (71%), 8 (26%) and 1 (3%) isolates, respectively. The floR genes were detected in 8 (100%) of the 8 florfenicol-resistant A. pleuropneumoniae isolates.

We report a case of acute septic arthritis of the hip in a child due to H. influenzae with review of the problems encountered. A one year and 9 months-old male child was admitted because of fever, limping and restlessness of 48-hour duration. Under the impression of septic arthritis of the right hip, blind broad-spectrum antibiotic regimen was initially instituted. Fever subsided immediately and two blood cultures yielded no growth, as did joint tapping. But fever recurred on the 8th day of admission. MRI demonstrated fluid collection in the right hip. Arthrotomy yielded thin pus. The antibiotic regimen was shifted to vancomycin, according to the culture report of S. aureus. However, spiking fever continued. On the 4th week of admission, recheck MRI demonstrated fluid collection in and out of the hip joint. A second arthrotomy yielded frank pus. H. influenzae was reported in pus culture for the first time, being susceptive only to chloramphenicol. Fever was down to normal temperature after injection of urfamycin. Radiograph on the 17th day after the 2nd arthrotomy revealed posterior dislocation of the right hip. MRI demonstrated granulation tissue within the acetabulum. Open reduction confirmed granulation tissue without pus. This case suggests: 1. Routine blind antibiotic regimen for gram-positive and negative organisms in the initial phase of treatment may fail in the rare case of H. influenzae. This may lead the surgeon to miss the optimum time of surgical intervention despite early diagnosis, 2. Arthrotomy may fail if not followed by antibiotics sensitive to the pathogen. 3. Delayed pathologic dislocation may ensue due to invasion of granulation tissue.

Seventy Escherichia coli isolates recovered from diseasedchickens diagnosed with colibacillosis in Henan Province,China, between 2004 and 2005 were characterized forantimicrobial susceptibility profiles via a broth doublingdilution method. Overall, the isolates displayed resistanceto trimethoprim-sulfamethoxazole (100%), oxytetracycline(100%), ampicillin (83%), enrofloxacin (83%), and ciprofloxacin(81%), respectively. Among the phenicols, resistance wasapproximately 79% and 29% for chloramphenicol andflorfenicol, respectively. Molecular detection revealed thatthe incidence rates of the floR, cmlA, cat1, cat2 and cat3were 29, 31, 16, 13, and 0%, respectively. Additionally,10% of the isolates were positive for both floR and cmlA.As these antimicrobial agents may potentially inducecross-resistance between animal and human bacterialpathogens, their prudent use in veterinary medicine ishighly recommended.
