| description |
Feline upper respiratory infection and feline pyothorax are common complaints
in veterinary practice that can be caused by zoonotic bacteria. The study aimed
to characterise clinical features, diagnostic imaging and laboratory findings in
cats with upper respiratory tract infection and pyothorax, both retrospectively and
prospectively. History, signalment and physical examination information of the
cats were obtained. Laboratory findings including haematology, biochemistry,
cytology, bacterial identification and diagnostic imaging findings were analysed.
Additional virus testings for feline calicivirus, feline herpesvirus, feline
coronavirus, feline leukaemia virus and feline immunodeficiency virus were
conducted in the prospective study. Results showed that most cats had access
to outdoors and were from multi-cat household. In both retrospective studies,
common clinical signs such as sneezing, mucoid or mucopurulent nasal
discharge and stertorous breathing were predominantly observed in cats with
upper respiratory infection; while dyspnoea, harsh or dull lung sound and open
mouth breathing were predominantly observed in cats with pyothorax. In the
prospective study, nasal discharge, cough and stertor were commonly observed
in cats with upper respiratory infection; while abdominal breathing, dehydration
and inactivity were observed in cats with pyothorax. Hyperglobulinaemia and
hyperproteinaemia were common clinicopathologic abnormalities observed in
retrospective cases of feline upper respiratory infection and pyothorax.
Additionally, monocytosis and leucocytosis were also common clinicopathologic
abnormalities presented in retrospective cases of pyothorax cats. In the
prospective study, the majority of the cats with upper respiratory infection or
pyothorax had high antibody titres of feline herpesvirus and feline calicivirus,
positive for feline coronavirus antibody, negative for feline leukaemia virus
antigen and feline immunodeficiency virus. Diagnostic imaging of both
retrospective and prospective studies revealed that fluid/soft tissue attenuated
turbinates and sinuses were common in cats with upper respiratory infection;
while pleural fluid, lung consolidation and obscured cardiac silhouette were
common in cats with pyothorax. In retrospective studies, Staphylococcus spp.,
Pasteurella multocida and Streptococcus spp. were common in cats with upper
respiratory infection; whereas, Pasteurella multocida, Streptococcus spp. and
Escherichia coli were common in cats with pyothorax. In the prospective study,
Pasteurella multocida was the most common bacterium in both upper respiratory
infection and pyothorax cases. Beta-lactam group antimicrobials and
doxycycline remained suitable choices of antimicrobial treatment in cases of
feline upper respiratory infections while amoxicillin–clavulanate showed good
antimicrobial susceptibility against aerobic bacteria isolated from the cases in the
pyothorax study. The case outcomes of the cats were similar for both diseases.
In the retrospective study of cats with feline upper respiratory infection, 15 cats
(48.4%) recovered after treatment while 16 cats (51.6%) were dead or
euthanised. Whereas, in the retrospective study of pyothorax cats, only 13 cats
(46.4%) survived while 15 cats (53.6%) died at the point of re-evaluation. The
study contributed to the understanding of feline upper respiratory infection and
pyothorax in relation to clinical manifestations and diagnostic imaging features.
Moreover, from the bacteria that were isolated, the study highlights the possible
risk of zoonotic disease transmission from feline pets to human owners and
emphasises the importance of disease prevention. |
