Undifferentiated distal respiratory tract disease (nasal discharge, cough, pneumonia) in foals (1 to 8 months old) is a burdensome economic problem on breeding farms; yet, the infective agents associated with these episodes have not been well described. Possible causes of these episodes of illness were investigated by culturing specimens of proximal and distal airways of clinically diseased foals (n = 101), prior to any treatment, for aerobic and anaerobic bacteria and viruses (rhinoviruses, equine arteritis virus, equine herpesvirus subtype 1 [EHV-1], influenza virus, and adenovirus). Pairs of sera (n = 47) were examined for antibodies to influenza A virus, equine subtypes 1 and 2, EHV-1, and adenovirus antigens, and sera obtained from foals during acute infection were examined for antibodies (by agar gel immunodiffusion [AGID]) to equi factor antigens of Rhodococcus equi. Viruses were not isolated from the proximal (swab) or distal (bronchial lavage) airway specimens in foals, and only 2 of 47 randomly selected foals seroconverted to EHV-1. Serotiters to the other viruses were low and frequently decreasing between samples, which was compatible with maternally derived antibody. Streptococcus zooepidemicus was the predominant isolate from bronchial lavage specimens (88/101 cases), accompanied by alpha-hemolytic streptococci (8 cases), Bordetella bronchiseptica (13 cases), Staphylococcus epidermidis (9 cases), and other organisms in lesser frequency. Only Str zooepidemicus was recovered significantly (P < 0.05) more often in cases than in controls. The AGID test was found useful to detect foals with presumed exposure to R equi, but positive tests results did not correspond well with bacterial culture results; positive AGID results were recorded in 34% of culture-negative foals.(ABSTRACT TRUNCATED AT 250 WORDS)

Within the scope of the clinical evaluation of Tilmicosin in Enzootic Pneumonia of pigs, nasal swabs from 78 animals were taken, before and after oral medication of different doses (0, 100, 200, 300 mg Tilmicosin/kg dry food), and examined bacteriologically for Pasteurella multocida, Bordetella bronchiseptica und Haemophilus parasuis. The bacteria aforementioned were isolated from the nasal secretions of 83% of the pigs, 14 days after crowding without any prophylactic regime. It could be demonstrated, that pigs with clinical symptoms of Enzootic Pneumonia had a 50% higher prevalence-rate of multi-colonization with pneumotropic bacteria than healthy animals. Feeding 300 mg Tilmicosin/kg food for 9 and 14 days respectively, resulted in elimination of Pasteurella spp. and Haemophilus spp. The rate of newly Bordetella bronchiseptica infected pigs was lower than in the placebo-group. Parallel to these bacteriological results improvement of clinical signs and increased daily weight gain were observed.

A 3-year-old male koala (Phascolarctos cinereus) was evaluated because of severe acute respiratory distress. Despite medical treatment, the koala died. Gross and histologic lesions consistent with acute bacterial pneumonia were identified at necropsy and Bordetella bronchiseptica was isolated from pulmonary tissue. There are 2 prior reports from Australia of fatal B bronchiseptica pneumonia in captive koalas.

Nasal swabs and lungs of 150 pigs with pneumonia were tested by culture at post mortem examination. The isolated agents were Pasteurella multocida (P.m.), P. haemolytica, Bordetella bronchiseptica, Actinobacillus pleuropneumoniae, Staphylococcus aureus, Streptococcus spp. and Escherichia coli. P.m. was most frequently found, and this agent only showed a significant correlation between lungs and nasal swabs. In 80.6% of pigs with P.m. in the lung the agent was detected in the nose, too. Drug resistance patterns of P.m. isolates from lungs and noses of the single animals were identical or similar, also in case of different capsular types. The examination of porcine nasal swabs for bacteria capable of causing pneumonia should be limited to P. multocida. Demonstration of agents in lung material is generally more certain.

Eleven cats from 10 different households or catteries were diagnosed with Bordetella bronchiseptica (B. bronchiseptica) infections. Seven cases proved fatal, in which B. bronchiseptica pneumonia was a primary or significant cause of death. The majority of cases (seven of 11) were in kittens less than eight weeks old. A universal complaint was coughing. Bacterial cultures from transtracheal washes or lung tissue were successful in diagnosing bordetellosis in all cases. This report indicates that B. bronchiseptica should be a consideration in a cat presenting with a primary complaint of coughing and may be a relatively common disease in catteries or shelter environments.

Fifteen athymic rat strains from 11 breeding colonies were housed within an experimental facility for an immunological study. Health status records supplied with 14 of the strains listed infections by Kilham's rat virus (KRV), Clostridium piliforme (Bacillus piliformis) and Pasteurella pneumotropica for 2, 2 and 1 colonies respectively. In sera taken previous to the study from euthymic rats of 10 strains, antibodies to KRV were detected in 3 strains, to Pneumonia virus of mice (PVM), Rat corona virus (RCV) and Sendai virus in one strain each and to P. pneumotropica in 2 strains. Only 2 of the KRV infections had been reported by the supplier. During the study rats of all 10 strains developed antibodies to 2-4 of viral antigens. Eight out of 10 rat strains seroconverted to 1-5 of the antigens C. piliforme (B. piliformis), Bordetella bronchiseptica, Haemophilus spp., P. pneumotropica and Streptobacillus moniliformis. Two rat strains housed in filtertop cages did not develop antibodies to bacterial antigens. The potential detrimental effects of intercurrent infections on the outcome of the comparative immunological study are discussed.

Bronchoalveolar lavage was performed in 128 pigs from five fattening units showing acute pneumonia (48 animals), subclinical purulent pneumonia (17 animals), and chronic purulent pneumonia (63 animals). These samples were investigated for bacteria. Additionally immunofluorescence microscopy as well as serological investigations were performed to detect antibodies against several bacteria and viruses. Pasteurella multocida could be detected in more than a half of the samples of pigs with acute pneumonia. Bordetella bronchiseptica and mycoplasmas were isolated in a lower amount. Probably these bacteria infected the pigs of at least one herd after a primary infection with influenza virus because (i) influenza virus could be detected in three of four animals investigated for influenza virus by culture methods, (ii) the virus could be detected in one third of the animals investigated for by immunofluorescence microscopy, and (iii) antibodies against influenza virus could be detected in almost all animals. From pigs with subclinical purulent pneumonia Bordetella bronchiseptica as the only bacterial lung pathogen could be isolated exclusively from nearly each sample. From the samples of pig suffering from chronic purulent pneumonia first of all Bordetella bronchiseptica, Pasteurella multocida and different mycoplasma species could be detected. Using cultural methods Actinobacillus pleuropneumoniae could be isolated from six samples only, in contrast to frequent positive reactions against Actinobacillus pleuropneumoniae antigens obtained by immunofluorescence microscopy and CFT.

Respiratory infections, especially community-acquired forms of pneumonia (CAP), are challenging for clinicians because (1) a causative microorganism can only be found in about 50% of cases; (2) initial therapy, therefore, must be based on a probable or most likely etiology in the context of the patient's overall medical condition; and (3) new microbes or those considered previously as normal flora or less virulent forms seem responsible for some cases. It is important to be acquainted with new causes of infection which include Legionella species, Chlamydia pneumoniae, diphtheroids in certain instances (Corynebacterium pseudodiphtheriticum), and viruses such as the Hanta strains. Infections with Bordetella pertussis are increasing. However, the ever present and most common cause of CAP, Streptococcus pneumoniae, continues to present problems because of increasing antibiotic resistance, the high case fatality rate when bacteremia accompanies pneumonia, and the inability to give prophylactic immunization to all people with risk factors for this infection.

Bordetella bronchoseptica is a rarely reported cause of human infection, but is a common respiratory tract commensal of mammals. Human infection with B. bronchoseptica is almost always associated with severe underlying disease and contact with an appropriate animal reservoir. We report a case of pneumonia with shock caused by B. bronchoseptica in an immunocompetent patient.
