A 2-year-old Himalayan cat was presented for investigation of chronic, persistent, unilateral nasal discharge that was unresponsive to antibiotics. Unilateral choanal atresia was diagnosed on nasopharyngoscopy. Following surgical repair using the transnasal route and temporary stenting all clinical signs resolved. This is the first reported case of choanal atresia in a cat. It serves to alert practitioners to the occurrence of this unusual condition which should be included in the differential diagnoses of upper respiratory tract signs in young cats.

The major clinical problem in considering a diagnosis of sinusitis is differentiating uncomplicated upper respiratory tract infection from a secondary bacterial infection of the paranasal sinuses that may benefit from antimicrobial therapy. A diagnosis of sinusitis is suggested by presentation with protracted upper respiratory tract symptoms or a cold that is more severe than usual with fever and purulent nasal discharge. Confirmatory tests of sinus disease are transillumination (useful in adolescents if interpretation is confined to the extremes — normal or absent); radiographic findings of opacification, mucous membrane thickening, or an air-fluid level; and sinus aspiration (indicated for severe pain, clinical failures, or complicated disease). When clinical signs and symptoms are accompanied by abnormal radiographic findings, bacteria in high colony count are recovered from the maxillary sinus aspirate in 70% of patients. The common bacterial species recovered from children with acute maxillary sinusitis are Streptococcus pneumoniae, Moraxella (Branhamella) catarrhalis, and Hemophilus influenzae.

Abstract Bacterial diseases of the upper respiratory tract accompanied with various degrees of clinical signs are relatively frequent in a small animal clinical practice. The clinical signs are usually mild, mostly connected with clinical manifestation of nasal discharge, mild dyspnoea, sneezing, and coughing; however, in some cases they may convert to a chronic stage with serious systemic manifestations. The course and development of complications depends on the etiological agent and the success or failure of the subsequent therapy. An accurate diagnosis is of the upmost importance in order to develop an appropriate therapeutic plan for disease management. The present study focused on: endoscopic visualisation of the upper respiratory tract of the affected animals; localisation of pathological changes, and the targeted collection of the samples. This clinical study involved 26 patients with long-term signs of the affected airways that progressed to chronic stages after the failure of the prescribed therapy. Each patient was clinically examined, sedated and subjected to an endoscopic examination that involved the collection of samples. The samples were examined microbiologically, tested for antibiotic resistance, and a targeted therapy was implemented. The endoscopic and complex microbiological diagnosis enabled: more effective management of the bacterial infection; shortening of the therapy; and a convalescence period that reduced the risk of the development, or the spreading of resistant bacteria.

The breadth of animal hosts that are susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and may serve as reservoirs for continued viral transmission are not known entirely. In August 2020, an outbreak of SARS-CoV-2 occurred in multiple mink farms in Utah and was associated with high mink mortality and rapid viral transmission between animals. The outbreak's epidemiology, pathology, molecular characterization, and tissue distribution of virus within infected mink is provided. Infection of mink was likely by reverse zoonosis. Once established, infection spread rapidly between independently housed animals and farms, and caused severe respiratory disease and death. Clinical signs were most notably sudden death, anorexia, and increased respiratory effort. Gross pathology examination revealed severe pulmonary congestion and edema. Microscopically there was pulmonary edema with moderate vasculitis, perivasculitis, and fibrinous interstitial pneumonia. Reverse transcriptase polymerase chain reaction (RT-PCR) of tissues collected at necropsy demonstrated the presence of SARS-CoV-2 viral RNA in multiple organs including nasal turbinates, lung, tracheobronchial lymph node, epithelial surfaces, and others. Whole genome sequencing from multiple mink was consistent with published SARS-CoV-2 genomes with few polymorphisms. The Utah mink SARS-CoV-2 strain fell into Clade GH, which is unique among mink and other animal strains sequenced to date and did not share other spike RBD mutations Y453F and F486L found in mink. Localization of viral RNA by in situ hybridization revealed a more localized infection, particularly of the upper respiratory tract. Mink in the outbreak reported herein had high levels of virus in the upper respiratory tract associated with mink-to-mink transmission in a confined housing environment and were particularly susceptible to disease and death due to SARS-CoV-2 infection.

Objectives The aim of this study was to assess the effects of famciclovir administration in cats with spontaneously acquired acute upper respiratory tract disease. Methods Twenty-four kittens with clinical signs of acute upper respiratory tract disease were randomly allocated to receive doxycycline (5 mg/kg PO q12h) alone (group D; n = 12) or with famciclovir (90 mg/kg PO q12h; group DF; n = 12) for up to 3 weeks. Clinical disease severity was scored at study entry and daily thereafter. Oculo-oropharyngeal swabs collected at study entry and exit were assessed using quantitative PCR for nucleic acids of feline herpesvirus type 1 (FHV-1), feline calicivirus (FCV), Chlamydia felis, Bordetella bronchiseptica and Mycoplasma felis. Results The median (range) age of cats was 1.5 (1–6) months in group D vs 1.6 (1–5) months in group DF ( P = 0.54). Pathogens detected in oculo-oropharyngeal swabs at study entry included FCV (n = 13/24; 54%), M felis (n = 8/24; 33%), FHV-1 (n = 7/24; 29 %), C felis (n = 7/24; 29%) and B bronchiseptica (n = 3/24; 12%). Median (range) duration of clinical signs was 11.5 (3–21) days in group DF and 11 (3–21) days in group D ( P = 0.75). Median (range) total disease score at the end of the study did not differ between groups (group D 1 [1–1] vs group DF 1 [1–3]; P = 0.08). Conclusions and relevance This study revealed no significant difference in response to therapy between cats treated with doxycycline alone or with famciclovir; cats improved rapidly in both groups. However, identification of FHV-1 DNA was relatively uncommon in this study and clinical trials focused on FHV-1-infected cats are warranted to better evaluate famciclovir efficacy.

Acute infectious and inflammatory diseases of the upper respiratory tract today belong to the category of the most common pathological conditions. Most often they occur in the form of acute nasopharyngitis, acute rhinosinusitis and acute laryngitis, the clinical of which consists of such symptoms as general weakness, hyperthermia, nasal blockage and nasal discharge, dysosmia, pain and tickling in the throat, cough, dysphonia. The need to select a safe and effective mucoactive therapy justifies the use of the phytopreparation in this pathology, the main active ingredient of which is an extract of ivy leaves. Also in the composition of the drug includes anise oil, peppermint oil, eucalyptus oil and levomenthol. The mechanism of action of is associated with α-hederin contained in ivy leaves. This substance, binding to the beta-adrenoreceptors of the bronchi, causes relaxation of their smooth muscles. In addition, thanks to the saponins contained in the leaves of common ivy, a mucolytic and expectorant effect is achieved. Literature data show that ivy leaf preparations significantly reduce the severity of acute respiratory infections of the upper respiratory tract. Virtually none of the patients had severe side effects. Allergic reactions were recorded in less than 0.5% of cases, with no mention of a severe allergic reaction of the anaphylaxis type. Thus, the drug of plant origin in the form of drops can be successfully used in patients with symptoms of acute respiratory diseases.

Infections caused by Streptococcus suis (S. suis) pose a problem for the pig industry worldwide. Pigs often carry multiple serotypes of S. suis in the upper respiratory tract, where S. suis is frequently isolated from. The clinical diagnosis of the infection is presumptive and is generally based on clinical signs, the age of the animal and macroscopic lesions. In the laboratory, identification of S. suis is performed biochemically, and then, serotyping is performed with antisera to determine the serotype, but these tests can be inconclusive. To date, there are few studies that have documented the presence and diversity of S. suis serotypes in Mexico. In the present study, it was characterized S. suis strains from Mexican pig farms using molecular approaches; samples were first processed by PCR of the gdh gene to detect S. suis. Positive samples were then subjected to a two-step multiplex PCR (cps PCR) to detect and characterize each strain; the first step consisted of a grouping PCR and the second step consisted of a typing PCR. The serotypes detected in the pig farming areas of Mexico included 1/2, 2, 3, 5, 7, 8, 9, 17, and 23. These findings are important for the characterization of serotypes present in Mexico and for outbreak prevention.

Feline calicivirus is among the most common pathogenic microorganisms in upper respiratory tract disease (URTD) and oral lesions of cats. It leads to stomatitis, oral ulceration, ocular and nasal discharge, conjunctivitis, fever, lameness, anorexia, hypersalivation, pneumonia, respiratory distress, coughing, and depression in infected cats. This study aimed to determine the role of Feline calicivirus (FCV) in cats with the upper respiratory tract disease in the Diyarbakir region, Turkey, to provide treatment for infected cats and contribute to the disease prophylaxis. The study material consisted of 10 cats (control group) considered to be healthy according to the clinical examination and 20 cats with URTD that were not vaccinated against Feline calicivirus infection of different breeds, ages, and genders brought to Dicle University Veterinary Faculty Prof. Dr. Servet SEKIN Polyclinic with URTD. After routine clinical examinations of the animals, oral and conjunctival swabs and blood samples were taken. Hematological and biochemical analyzes of blood samples were performed. Swab samples were analyzed by the polymerase chain reaction (PCR) method for the diagnosis of the agent. Oral lesions, hypersalivation, ocular and nasal discharge, coughing, and breathing difficulties were seen in clinical examinations of cats with URTD. Feline calicivirus was detected in only one cat’s conjunctival swab sample in PCR analyses. As a result, we found that Feline calicivirus infection was present in cats with URTD in the Diyarbakir region, and 5% positivity was found in cats with clinical symptoms according to PCR analysis.

Sixteen pathogen-free cats were exposed by aerosol to either of two feline picornavirus isolates. The isolates used were picornavirus-255 and kidney-cell-degenerating virus. These viruses were selected to represent picornavirus prototypes of high and low virulence, respectively. Picornavirus-255 consistently produced depression, anorexia, and pneumonia. There were no lesions in the upper respiratory tract or conjunctiva, nor were there clinical signs of upper respiratory disease. The pulmonary lesions began as multifocal exudative pneumonia that progressed rapidly to interstitial pneumonia characterized by marked adenomatoid proliferation of pneumocytes. Three weeks after exposure the pulmonary lesions were principally resolved. It also produced discrete lingual and palatine ulcers that were easily detected. Experimental infection with kidney-cell-degenerating virus resulted only in transient fever and tiny vesicles and ulcerations of the lingual and tonsillar mucosae that could easily escape detection. No significant respiratory lesions were induced by kidney cell degenerating virus.

AbstractObjective:This paper describes and discusses the case of an oesophageal foreign body, in which the patient presented with primarily respiratory clinical signs.Case report:A 17-month-old child, who had ingested a watch battery, presented to emergency services on multiple occasions with upper respiratory tract symptoms. Subsequent radiographs showed the battery in the oesophagus impinging on the trachea. The battery was removed successfully under a general anaesthetic.Conclusion:Large oesophageal foreign bodies can impinge on the trachea causing upper respiratory tract signs. In such cases, anteroposterior and lateral chest films are imperative to make a correct diagnosis.
