We present a case involving a 74-year-old woman with cat scratch disease characterized by an enlarged and hard axillary lymph node as well as a palpable breast nodule mimicking a carcinoma. The lymph node and the breast nodule were excised. The pathologic examinations revealed granulomatous lymphadenitis with gram-negative bacilli and an intraductal papilloma. Antibiotic therapy (azithromycin) was prescribed and the patient's clinical evolution was excellent.

Introduction: Pasteurella multocida is a gram-negative coccobacillus pathogenic to animals. It can cause infection in humans by a bite, scratch, or lick from a cat or dog. P. multocida can cause a variety of infections in humans, including cellulitis, osteomyelitis, endocarditis, peritonitis, and septic shock. Case Presentation: A 56-year-old male presented to our hospital with a 2-day history of fever, abdominal pain, nausea, and vomiting. He denied exposure to cats, dogs or other pets...

Infections caused by the Bartonella species are responsible for the human diseases collectively called 'bartonellosis'. The clinically important human infections are mostly caused by the three species (eg, B. bacilliformis, B. quintana and B. henselae ) of Bartonella out of the many progressively increasing identified species. Bartonella henselae transmitted by the arthropod vector, fleas, after cat bite is responsible for the rare multisystem cat scratch disease in humans. We present an extremely rare case of B...

Cat scratch disease (CSD) typically manifests as a febrile lymphadenopathy and is caused by a Bartonella henselae infection after contact with cats. This article describes the case of an atypical presentation of CSD in a 52-year-old patient with acute unilateral loss of vision and headache without fever or lymphadenopathy. Funduscopic examination showed an optic disc swelling and macular star exsudates, pathognomonic for infectious neuroretinitis. A Bartonella henselae infection was confirmed serologically...

Feline idiopathic head-and-neck dermatitis-also named feline idiopathic ulcerative dermatitis (IUD)-is considered as a rare skin disease of unknown origin. It is usually associated with a crusted, non-healing, self-induced ulcer occurring most commonly on the dorsal or lateral neck or between the scapula where self-grooming by scratching occurs. Usually, IUD is diagnosed after exclusion of other causes of pruritus. In feline medicine, self-induced alopecia is recognized as a behavioral disorder (abnormal repetitive behavior) due to excessive licking, which is an amplification of a normal maintenance behavior...

Practical relevance: Cats are descended from a solitary, territorial ancestor, and while domestication has reduced their inherited tendency to be antagonistic towards all animals larger than their typical prey, they still place more reliance on the security of their territory than on psychological attachments to people or other cats, the exact opposite to dogs. Many feline problem behaviours stem from perceived threats to this security, often due to conflicts with other cats. Others are more developmental in origin, often caused by inadequate exposure to crucial stimuli, especially people, during the socialisation period...

Cats and cat fleas (Ctenocephalides felis) are vectors of the zoonotic bacterial pathogens Bartonella henselae and Rickettsia felis, which are the causative agents of "cat scratch disease" and "cat flea typhus," respectively. In the surroundings of Vienna (Austria), we identified 11 (10.5%; n = 105) B. henselae-positive fleas originating from 8 cats (20.5%; n = 39). One flea was positive for R. felis. There should be high levels of awareness among veterinarians and animal keepers as to the handling of cats, especially if free roaming, stray, or feral...

We used real-time PCR to detect Bartonella henselae DNA in 7.9% (5/63) of blood specimens from seronegative patients in Japan suspected of having cat-scratch disease. The combined use of serologic tests and real-time PCR to analyze blood specimens is recommended for the prompt, noninvasive laboratory diagnosis of cat-scratch disease.

In a previous report, we found neurons with ON-OFF and OFF-ON firing activity in the obex reticular formation during scratching. The aim of the present study was to examine whether the spinal neurons also exhibit this type of activity in relation to the "postural stage" of fictive scratching in the cat. We found that the extensor and intermediate scratching neurons exhibit an ON-OFF firing rate; conversely, the flexor neurons show an OFF-ON activity, relative to every scratching episode. These patterns of spiking activity are similar to those found in neurons from the obex reticular formation during scratching...

BACKGROUND: Qatar is one of the wealthiest and fastest growing economies in the world, experiencing a rapid increase in human and pet populations. Given the paucity of data on prophylactic measures against endo- and ectoparasites of pets in Qatar, as well as on the owners' awareness of zoonotic diseases, a questionnaire was conducted. METHODS: From July to November 2017, 150 multiple-choice questionnaires were administered to dog and/or cat owners who attended two veterinary clinics in Doha...

We report the case of a 53-year-old healthy man, presenting with confusion. The patient had been clinically diagnosed with cat-scratch disease (CSD) and prescribed a 10-day course of doxycycline orally. Approximately a week after he had completed the treatment, he was admitted to our department with confusion. Neurological examination revealed expressive dysphasia with no motor or sensory deficits. Cerebrospinal fluid (CSF) examination showed only increased content. Imaging with CT and MRI of the brain did not reveal any abnormalities, and funduscopy was normal...

BACKGROUND: Bartonella henselae is the causal agent of cat scratch disease in immunocompetent persons and bacterial angiomatosis in immunocompromised patients. In Chile, the prevalence of antibodies against B. henselae in healthy children and adolescents is 13.3%, in persons with occupational risk 60.5%, and in cats 85.6%. There are no published data regarding the seroprevalence in blood donors in our country, so determining if B. henselae is present in the blood of donors at the time of donation is very important, since this microorganism can survive up to 35 days in the red blood cells stored in a blood bank at 4 °C...

Capnocytophaga canimorsus is a commensal organism commonly found in the oral cavity of cats and dogs. Infections with this organism are rare and can affect both immunocompetent and immunocompromised individuals. The authors present a case of C canimorsus causing indolent prosthetic hip joint infection in a healthy 66-year-old woman following a history of being scratched by her pet dog. The patient had an atypical history of chronic, low-grade infection which is unusual, as this organism is more frequently associated with acute presentations and fulminant sepsis...

Pasteurella multocida is rarely observed in human chronic infections. A Pasteurella multocida strain was isolated from a skin biopsy of chronic dermohypodermitis in a 21-year-old woman without an immunocompromised state. As this strain was viable one month after a cat scratch despite treatment by amoxicillin-clavulanic acid, we compared this strain's growth rate, amoxicillin Minimal Inhibitory and Bactericidal Concentrations (MIC and MBC), resistance to serum and ability to activate neutrophil granulocytes with those of control strains isolated during acute infections in humans without previous antibiotics exposure...

A healthy patient presented with painful skin lesions on the anterior surface of her legs. Erythema nodosum was diagnosed but all the usual causes were ruled out. The finding of bilateral enlarged axillary lymph nodes with necrosis and granulomas led to the diagnosis of Bartonella infection, an unusual cause of erythema nodosum. Imaging also revealed splenomegaly and small para-aortic lymph nodes. Up to one quarter of the patients with cat-scratch disease present atypically, a considerably higher prevalence than previously reported...
