Abstract
Respiratory tract disease can be associated with primary or secondary bacterial infections in dogs and cats and is a common reason for use and potential misuse, improper use, and overuse of antimicrobials. There is a lack of comprehensive treatment guidelines such as those that are available for human medicine. Accordingly, the International Society for Companion Animal Infectious Diseases convened a Working Group of clinical microbiologists, pharmacologists, and internists to share experiences, examine scientific data, review clinical trials, and develop these guidelines to assist veterinarians in making antimicrobial treatment choices for use in the management of bacterial respiratory diseases in dogs and cats.

Abstract
Background Marbofloxacin is a third-generation fluoroquinolone developed solely for veterinary medicine with a broad spectrum of antibacterial activity against some Gram-positive and most Gram-negative bacteria, including the bovine respiratory tract pathogen, Pasteurella multocida. The objective of our study was to elucidate the pharmacokinetics and pharmacodynamics of marbofloxacin in a Pasteurella multocida infected murine lung model, and to estimate the magnitudes of pharmacokinetics-pharmacodynamics parameters associated with various effects. Results The pharmacokinetic studies revealed marbofloxacin kinetics in infected mice were linear over a dose ranging from 1.25 to 10 mg/kg of body weight. The protein binding in the plasma of neutropenic infected mice was 29.77 %. The magnitudes of the ratio of the free-drug area under the concentration-time curve over 24 h to MIC (fAUC0-24h/MIC) associated with static effect, a 2 log10 reduction and a 3 log10 reduction of bacterial counts were 40.84, 139.34, and 278.08 h, respectively. Conclusions Based on the dose range study, marbofloxacin exhibited concentration-dependent killing and the fAUC/MIC was the PK/PD index that correlated best with efficacy (R2 = 83 %). On the basis of a bactericidal effect goal of fAUC0-24h/MIC of 278.08 h, if marbofloxacin is used for the treatment of P. multocida serious lung infection with an MIC90 of 0.12 μg/ml, the current dose (2 mg/kg) would fail to achieve a bactericidal effect. It would benefit from higher doses (4 ~ 6 mg/kg) than those commonly used in clinical practice.

Abstract
The fluoroquinolone antimicrobial drug marbofloxacin was administered to yellow cattle intravenously and intramuscularly at a dose of 2 mg/kg of body weight in a two-period crossover study. The pharmacokinetic properties of marbofloxacin in serum, inflamed tissue-cage fluid (exudate), and noninflamed tissue-cage fluid (transudate) were studied by using a tissue-cage model. The in vitro and ex vivo activities of marbofloxacin in serum, exudate, and transudate against a pathogenic strain of Pasteurella multocida (P. multocida) were determined. Integration of in vivo pharmacokinetic data with the in vitro MIC provided mean values for the area under the curve (AUC)/MIC for serum, exudate, and transudate of 155.75, 153.00, and 138.88, respectively, after intravenous dosing and 160.50, 151.00, and 137.63, respectively, after intramuscular dosing. After intramuscular dosing, the maximum concentration/MIC ratios for serum, exudate, and transudate were 21.13, 9.13, and 8.38, respectively. The ex vivo growth inhibition data after intramuscular dosing were fitted to the inhibitory sigmoid Emax equation to provide the values of AUC/MIC required to produce bacteriostasis, bactericidal activity, and elimination of bacteria. The respective values for serum were 17.25, 31.29, and 109.62, and slightly lower values were obtained for transudate and exudate. It is proposed that these findings might be used with MIC50 or MIC90 data to provide a rational approach to the design of dosage schedules which optimize efficacy in respect of bacteriological as well as clinical cures.

Abstract
In the title compound, [systematic name: 9-fluoro-2,3-dihydro-3-methyl-10-(4-methylpiperazin-1-yl)-7-oxo-7H-pyrido[1,2,3-ij][1,2,4]benzoxadiazine-6-carboxylic acid], C17H19FN4O4, the carbonyl and carboxyl groups are coplanar with the quinoline ring, making a dihedral angle of 2.39 (2)°. The piperazine ring adopts a chair conformation and the oxadiazinane ring displays an envelope conformation with the CH2 group at the flap displaced by 0.650 (2) Å from the plane through the other five atoms. The molecular structure exhibits an S(6) ring motif, owing to an intramolecular O—H⋯O hydrogen bond. In the crystal, weak C—H⋯F hydrogen bonds link molecules into layers parallel to the ab plane.

Abstract
Forty humane society cats with suspected bacterial upper respiratory infections (URIs) were studied in order to compare amoxycillin and pradofloxacin for treatment of rhinitis and describe common pathogens. Nasal discharges were collected prior to random placement into one of three treatment groups. Cats failing to initially respond were crossed to the alternate drug. Drug toxicity was not noted. The organisms most frequently isolated or amplified pre-treatment were feline herpesvirus-1 (75%), Mycoplasma species (62.5%), Bordetella species (47.5%), Staphylococcus species (12.5%) and Streptococcus species (10.0%). No differences in clinical scores between groups over time were noted. Overall response rates for amoxycillin at 22 mg/kg, q12 h for seven doses (10/15 cats; 67%), pradofloxacin at 5 mg/kg, q24 h for seven doses (11/13 cats; 85%), and pradofloxacin at 10 mg/kg, q24 h for seven doses (11/12 cats; 92%) were not statistically significant. Results suggest that pradofloxacin can be a safe, efficacious therapy for some cats with suspected bacterial URI.

Abstract
OBJECTIVE To study the hemodynamic effects of marbofloxacin (MBF) in isoflurane-anesthetized dogs. ANIMALS 6 healthy 8-month-old Beagles. PROCEDURE Anesthesia was induced with sodium thiopental and maintained with isoflurane. Cardiovascular variables were monitored throughout anesthesia. Marbofloxacin was administered by an IV bolus at 2 mg/kg, followed 10 minutes later by an infusion at a rate of 40 mg/kg/h for 30 minutes (total dose, 20 mg/kg). Plasma MBF concentrations were measured by high-performance liquid chromatography. RESULTS The mean peak concentration during MBF infusion was 34.2 +/- 6.4 microg/mL. The IV administration of the MBF bolus did not alter any cardiovascular variable in isoflurane-anesthetized dogs. Significant changes were found during infusion when a cumulative dose of 12 mg/kg had been given. The maximal decreases observed at the end of the infusion were 16% in heart rate, 26% in systolic left ventricular pressure, 33% in systolic aortic pressure, 38% in diastolic aortic pressure, 29% in cardiac output, and 12% in QT interval. All dogs recovered rapidly from anesthesia at the end of the experiment. CONCLUSIONS AND CLINICAL RELEVANCE MBF may safely be used at 2 mg/kg IV in isoflurane-anesthetized dogs, and significant adverse cardiovascular effects are found only when 6 to 8 times the recommended dose is given.

Abstract
OBJECTIVE To determine detection rates for feline herpesvirus type 1 (FHV-1), Mycoplasma spp, fungi, and bacteria in flush samples and biopsy specimens from the nasal cavities of cats with and without chronic rhinosinusitis (CRS). DESIGN Prospective study. ANIMALS 10 CRS-affected cats and 7 cats without signs of respiratory tract disease. PROCEDURES Nasal flush samples and biopsy specimens were collected from all cats for bacterial (aerobic and anaerobic), fungal, and mycoplasmal cultures; additional biopsy specimens were collected for virus isolation and polymerase chain reaction (PCR) assay (to detect FHV-1 DNA). RESULTS Aerobic bacteria were detected in flush samples from 5 of 7 control cats; culture of flush samples from CRS-affected cats yielded aerobic bacteria (9/10 cats), anaerobic bacteria (3/10), and Mycoplasma spp (2/10). No fungal organisms were isolated from any cat. Potential pathogens were isolated significantly more often from CRS-affected cats than from control cats. Bacterial culture of biopsy specimens yielded aerobic bacteria (2/7 control cats and 4/10 CRS-affected cats) and anaerobic bacteria (2/10 CRS-affected cats). Although FHV-1 was not detected in nasal biopsy specimens from control or CRS-affected cats, FHV-1 DNA was detected via PCR assay in specimens from 4 of 7 control cats and 3 of 10 CRS-affected cats. CONCLUSIONS AND CLINICAL RELEVANCE Compared with findings in control cats, anaerobic bacteria, Mycoplasma spp, and a variety of potentially pathogenic organisms were detected more commonly in samples from cats with CRS. In both groups, FHV-1 was detected via PCR assay as a nonviable organism or in noncultivable amounts.

Abstract
OBJECTIVES To determine pharmacokinetic characteristics of marbofloxacin after a single IV and oral administration and tissue residues after serial daily oral administration in chickens. ANIMALS 40 healthy broiler chickens. PROCEDURE Two groups of chickens (groups A and B; 8 chickens/group) were administered a single IV and oral administration of marbofloxacin (2 mg/kg). Chickens of group C (n = 24) were given serial daily doses of marbofloxacin (2 mg/kg, PO, q 24 h for 3 days). Plasma (groups A and B) and tissue concentrations (group C) of marbofloxacin and its major metabolite N-desmethyl-marbofloxacin were determined by use of high-performance liquid chromatography. Residues of marbofloxacin and N-desmethylmarbofloxacin were measured in target tissues. RESULTS Elimination half-life and mean residence time of marbofloxacin in plasma were 5.26 and 4.36 hours after IV administration and 8.69 and 8.55 hours after oral administration, respectively. Maximal plasma concentration was 1.05 microg/ml, and interval from oral administration until maximum concentration was 1.48 hours. Oral bioavailability of marbofloxacin was 56.82%. High concentrations of marbofloxacin and N-desmethyl-marbofloxacin were found in the kidneys, liver, muscles, and skin plus fat 24 hours after the final dose of marbofloxacin; however, marbofloxacin and N-desmethyl-marbofloxacin were detected in only hepatic (27.6 and 98.7 microg/kg, respectively) and renal (39.7 and 69.1 microg/kg, respectively) tissues 72 hours after termination of marbofloxacin treatment. CONCLUSIONS AND CLINICAL RELEVANCE Analysis of pharmacokinetic data obtained in this study reveals that a minimal therapeutic dose of 2 mg/kg, PO, every 24 hours should be appropriate for control of most infections in chickens.

Abstract
A short literature review of feline infectious pneumonia, feline Chlamydia and Paramyxoviridae is presented. In a retrospective study (from 1987 to 1996) 245 cases of feline pneumonia or conjunctivitis/rhinitis were investigated: histological diagnoses and aetiologies were compared; all lungs were examined immunohistologically for the occurrence of chlamydia and of canine distemper virus (CDV), but neither pathogen could be demonstrated. The results confirm previous reports indicating that feline chlamydia is not a primarily pulmonary pathogen and that CDV is not a causative agent of pneumonia in cats as it is in large felids. The review provides a summary of the known causes and pathology of infectious pneumonia in cats (in order of frequency), although some remain aetiologically uncertain. It focuses on chlamydia and distemper virus - a recognized and as yet unknown cause of feline pneumonia. The role and especially the frequency of chlamydia as a cause of feline pneumonia are controversial but distemper virus, known to cause pneumonia in dogs and large felids, has not as yet been demonstrated in cats. The aims of the retrospective study were to determine the occurrence of chlamydia in 245 cases of feline pneumonia or conjunctivitis/rhinitis, and to investigate the presence of CDV in these lungs.
