This case report describes a 70-year-old male with COPD who presented with cough, purulent sputum, fever and worsening breathlessness for one week. Sputum culture grew Pasteurella canis, a gram-negative bacteria commonly found in the oral flora of dogs and cats. The patient reported casual exposure to domestic cats. Treatment with doxycycline led to symptom improvement. This is the first reported case of P. canis causing exacerbation of COPD, suggesting casual exposure to pets may pose a respiratory infection risk for vulnerable patients. Close contact with animals should be avoided by elderly COPD patients to prevent Pasteurella pneumonia.

Repeated Hemoptysis With Progressive Bronchiectasis: A Case Report of Lady Wi...semualkaira
Bronchiectasis is a type of incurable structural lung disease with
clinical manifestations of chronic cough, expectoration or recurrent hemoptysis, which is often given anti-infection and symptomatic treatment. In this study, a patient suffering from bronchiectasis
with repeated hemoptysis caused by nontuberculous mycobacterium (NTM) was discussed. A 54-year-old female immunocompetent patient was admitted to our hospital due to repeated hemoptysis for 5 years. Computed tomography (CT) scan revealed progressive bronchiectasis in the upper and middle lobes of her right lung.
She subsequently underwent thoracoscopic lobectomy of the right
middle lobe plus segmentectomy of the anterior segment of the
right upper lobe. Postoperative pathological diagnosis was confirmed to be intracellular mycobacterium. In view of her results,
the patient was concluded to have “Lady Windermere syndrome”
and was clinically cured following 15 months of anti-NTM treatment.

Abstract—The aim of the study was to observe the prevalence of various microorganisms from throat swab specimens in patients attending a tertiary care hospital at Chinakakani, Guntur. Throat swab specimens were collected aseptically from 100 patients and cultured on appropriate bacteriological media. Isolates were identified by biochemical tests & antimicrobial susceptibility performed by standard methods. Out of 100 Samples, culture was positive in 25 samples. So Bacterial infection was found in 25% of Pharyngitis. Streptococcus pyogenes was the commonest isolate, followed by Staphylococcus aureus and Candida albicans. Majority of bacteria were Streptococcus pyogenes, Staphylococcus aureus and Candida albicans. In 60% it was mixed infection. The susceptibility patterns varied depending on the drugs, but most of the organisms were susceptible to penicillin, erythromycin and vancomycin. Improved personal hygiene and health education of the masses on how to care for ear, nose and throat will greatly reduce these microbial infections. This study will be useful for control strategies and for predicting pathogen prevalence in throat swabs.

Case Report
CASE REPORT
A 70-year-old male, hotel employee by occupation, known case
of Chronic obstructive pulmonary disease (COPD) and ischaemic
heart disease (IHD) presented to our hospital with a history of
cough with purulent expectoration, low grade fever and worsening
breathlessness of seven days duration. Patient had history of
recurrent exacerbations of COPD caused by Pseudomonas spp.
six months back. Patient was an active smoker and gave a history
of casual exposure to domestic cats.
On examination, patient was conscious, afebrile, tachypneic (res
piratory rate of 22/minute), mildly hypoxic (oxygen saturation on
room air of 88% by pulse oximetry) and haemodynamically stable.
Respiratory system examination revealed a barrel shaped chest
and bilaterally diminished breath sounds with diffused polyphonic
wheeze on auscultation. Routine blood investigations like haemo
gram, ESR, fasting blood glucose, renal function, serum electrolytes
and liver function were all within normal limits. Arterial blood gas
analysis was suggestive of mild Type I respiratory failure (pH= 7.36,
PaCO2
= 36 mmHg, PaO2
= 59.6 mmHg, PaHCO3
= 21 mmHg).
Chest radiograph showed changes of hyperinflation, unfolding of
aorta and no evidence of lung parenchymal abnormalities [Table/
Fig-1]. Spirometry was suggestive of severe obstructive impairment
with no significant bronchodilator reversibility. Sputum was sent for
gram stain, bacteriological culture and sensitivity testing. Patient
was treated with low flow oxygen, ceftriaxone 1 gram intravenously
BID, hydrocortisone and salbutamol + ipratropium nebulisations.
Response to initial therapy at the end of 48 hours was poor.
Gram stain smear of the sputum revealed numerous polymor
phonuclear leucocytes with gram negative coccobacilli and it was
decided to wait for the culture report before modifying the empiric
antibiotic.
The sample was cultured on blood agar, chocolate agar and
MacConkey’s agar plates and incubated at 37o
C for 24 hours.
Blood agar plates showed non haemolytic small dew drop colonies
and chocolate agar plates showed small grey coloured colonies and
the smear from the colonies showed the presence of gram negative
coccobacilli [Table/Fig-2,3]. There was no growth on MacConkey’s
agar plate. The isolate was catalase and oxidase test positive. The
isolate was further identified as Pasteurella canis by Vitek 2 system
(Bio-Mérieux, Co., Ltd.). Antibiotic susceptibility testing was done
by modified Kirby-Bauer disk diffusion technique. The organism

ABSTRACT
This is the report of lower respiratory tract infection with Pasteurella canis in a chronic obstructive pulmonary disease (COPD) patient
with history of casual exposure to cats. Pasteurella species are part of the oral and gastrointestinal flora in the canine animals. These
organisms are usually implicated in wound infection following animal bites, but can also be associated with a variety of infections
including respiratory tract infections.
was sensitive to ciprofloxacin, amoxicillin-clavulanic acid, penicillin,
gentamicin, clindamycin, levofloxacin, erythromycin, doxycycline
and trimethoprim-sulfamethoxazole ([Table/Fig-4], interpretation
with Haemophilus influenzae standards).
Taking into consideration the antibiotic sensitivity, parenteral
ceftriaxone was stopped and replaced by oral doxycycline along with
other supportive care. The patient showed gradual improvement
and was discharged on oral doxycycline for two weeks along
with inhaled bronchodilators. On follow up at two weeks, he was
asymptomatic and a repeat sputum culture revealed no significant
bacterial growth.
DISCUSSION
Pasteurella canis is a gram-negative, non-motile coccobacillus or
short rods belonging to the Pasteurellaceae family [1]. First referred
to as “Micrococcus gallicidus”, the generic name was redesignated
as “Pasteurella” in 1887 by Trevisan to commemorate the work
of Pasteur on these bacteria. Like most species of Pasteurella, P.

canis is oxidase and catalase test positive. It includes two biotypes:
biovar 1 is originated from canine, whereas biovar 2 is originated
from bovine animals. The two biotypes are distinguishable by the
indole test: biovar 1 is indole positive whereas biovar 2 is indole
negative [1].
P. canis are a part of the normal oropharyngeal flora of many animals
including healthy dogs and cats. In humans, they are known to
cause zoonotic infections. Human pasteurellosis most often results
in skin or soft tissue infections after an animal bite. P. multocida is
most commonly isolated in human infections but there have been
reports of other species such as P. canis and P. dogmatis being
involved [2]. P. canis is usually transmitted to human through animal
bites, licks. Dog bites are most commonly implicated followed by
cat bites. Exceptionally, some patients develop infections after
other animal exposure and in some infection may occur even in the
absence of an animal contact [3].
After soft tissue and wound infections, the respiratory tract is the
second most common site for Pasteurella infection. Most patients
with pulmonary infection due to Pasteurella are elderly with other
pre-existing chronic lung diseases like COPD, bronchiectasis,
or malignancy. The list of ‘pulmonary pasteurellosis’ includes
tracheobronchitis, pneumonia, lung abscess and empyema [4].
P.canis causing bacteremia, peritoneal dialysis-related peritonitis,
ocular infections including conjunctivitis outbreaks, osteomyelitis,
cutaneous abscess and septic arthritis in the immunocompromised
patients has been reported in the literature as well [5-9].
Pasteurella spp. is known to be susceptible to Penicillin G,
amoxicillin-clavulanate, piperacillin, fluoroquinolones (levofloxacin,
moxifloxacin), newer generation cephalosporins (ceftriaxone,
cefixime, cefpodoxime), doxycycline and carbapenems. Treatment
failures have been reported with the use of oral macrolides (e.g.
erythromycin), oxacillin, dicloxacillin, first generation cephalosporins
and clindamycin which should therefore be avoided [10].
Review of literature did not reveal any previous reports of P.canis
being implicated as a co-pathogen in COPD exacerbations, although
the organism itself finds mention as a causative agent in a multitude
of other system disease usually against a background of intimate
animal contact or trauma. In our patient, since there was only a casual
contact with cats and no history of a scratch or a bite from the animal,
we assume that he would have been exposed to secretions of his
pet animal through inhalation of contaminated aerosol. The isolation
of P. canis in the sputum of an elderly patient admitted with a COPD
exacerbation and the fact that he had only an insignificant history of
feline contact prompted us to report this case.
Kim et al., have also reported a case of respiratory tract infection
caused by P. canis in a COPD patient (poodle owner). This bacteria
is found in the oral secretions of canine animals and it can colonize
and infect the respiratory tract in patients with lung disease. The
patient was started on doxycycline and the symptoms improved.
The presentation of this case is similar to our case [11].
T Akahane et al., have reported dual infection with Pasteurella
dagmatis and P.canis in dog bite wound infection in a 25-year-old

female [12]. The other infections caused by Pasteurella species
reported in literature include cellulitis, subcutaneous abscesses
following dog and cat bite, endocarditis following a cat-bite,
vertebral osteomyelitis, spondylodiscitis in a diabetic patient [13,14].
Moreover, first case of association of P.canis, with bacteremia in a
cirrhotic patient with open leg was reported by Albert et al., [15].
However to the best of our knowledge, this is the first case of
exacerbation of COPD with Pasteurella species co-infection to be
reported from this region.
CONCLUSION
Obtaining a detailed history of animal exposure in COPD patients
is of paramount importance for the diagnosis of respiratory tract
infection caused by Pasteurella spp. Elderly patients with COPD
need to avoid close contact with pet animals as this could be a
potential risk factor for pneumonia caused by P. canis.
