“…Bartonella henselae was reported as the main species causing zoonotic infection, especially via cat-scratch disease. In Southeast Asia, it has been suggested that B. henselae and B. clarridgeiae are the species affecting human health and of veterinary importance [63]. In the main, B. henselae and B. clarridgeiae are transmitted to humans via cat fleas (C. felis) [64] which are generally found on cats and dogs worldwide [65] and C. felis is the major vector as the pathogen-transmissible insect for feline bartonellosis [66].…”

(1) Background: Bartonella spp. are Gram-negative, facultative, intracellular bacteria transmitted by hematophagous insects. Several species cause zoonotic diseases such as cat-scratch disease. Bartonella henselae and Bartonella clarridgeiae are the main species found in Thailand, however, there have been few studies on Bartonella spp. In addition, the hematological evaluation of Bartonella-infected animals is limited in Thailand. The aims of this study were prevalence investigation and hematological evaluation of Bartonella-infected dogs and cats residing in Bangkok, Thailand. (2) Methods: In total, 295 dogs and 513 cats were molecularly evaluated to detect Bartonella spp. using PCR with primers targeting the partial gltA, rpoB, ftsZ, ribC, and groEL genes. In total, 651 domestic animals were evaluated for hematological parameters compared between Bartonella-positive and Bartonella-negative animals. (3) Results: Overall, the prevalence of Bartonella spp. was 1.61% which was found only in free-ranging cats (2.83%). Bartonella henselae and B. clarridgeiae were confirmed from a concatenated phylogenetic tree of partial gltA and ribC genes, with 100% bootstrapping replication. For other housekeeping gene sequences, mixed infection was expected from the amplicons of rpoB, ftsZ, and groEL. Importantly, the mean corpuscular volume (MCV) was significantly increased in Bartonella-positive cats. (4) Conclusions: We suggest that B. henselae and B. clarridgeiae are important species and are still circulating in domestic animals, especially cats. The evaluation of blood parameters, especially a raised MCV, should be of concern in Bartonella infection in asymptomatic cats. Additionally, the knowledge of how to prevent Bartonella-related diseases should be promoted with people in at-risk situations.

“…Azithromycin has also been demonstrated to be an effective option for the treatment of CSD. Compared to doxycycline, azithromycin has the advantage of requiring less-frequent dosing and of having an increased safety profile [15]. Some authors believe the visual outcome may be improved with the use of oral corticosteroids in addition to antibiotics [9,14].…”

We report on a case of focal retinitis as the initial manifestation of cat-scratch disease. A 56-year-old Hispanic woman presented for a routine follow-up examination. A fundus examination of the right eye revealed a white retinal lesion along the inferotemporal artery; this lesion was noted to have progressed after one week of observation. On further inquiry, the patient reported she had seven cats at home, some of which were less than six months old and had recently scratched her. She received empirical treatment for focal retinitis with azithromycin (500 mg daily) and valacyclovir (1 g three times daily), which would cover the most common parasitic, viral, and bacterial etiologies. She was lost to a follow-up examination. However, she continued the same dose of antibiotic and antiviral treatment. Upon her eventual follow-up, three months later, it was noted that the lesion had resolved. The initial work-up revealed that she was positive for Bartonella henselae IgM (1:20) and IgG (1:512), as well as for B. quintana IgG (1:256); however, she was negative for B. quintana IgM. At a four-month follow-up appointment, the B. henselae IgM was negative, the IgG had decreased from 1:512 to 1:64, and the B. quintana antibody test was negative for IgM and IgG, all of which are consistent with an adequately treated case of cat-scratch disease. Focal retinitis can be a rare initial manifestation of cat-scratch disease, which should be considered part of the differential diagnosis in cases of focal retinitis, especially in patients with a history of close contact with young cats. Additionally, oral azithromycin may be considered as a treatment for some cases of cat-scratch-associated focal retinitis.

Ehrlichiosis is a disease in dogs caused by the bacterium Ehrlichia sp. and affects all ages and breeds. Ehrlichia sp. is an obligate intracellular bacterium, which means that this bacterium is able to enter into its host cells and its life depends on its host. This article was created to provide information regarding the management of Ehrlichia infection in dogs. The case animal is a mixed breed dog named Cio, 2 years old, female, weighing 11 kg. The dog come with complaints of itching and hair loss. The dog has a history of blood parasites (Ehrlichiosis) a year ago and has already been to the clinic. The blood test results found Ehrlichia sp and the test kit was positive. Based on the anamnesis, and the results of clinical and supporting examinations, the dog was diagnosed with ehrlichiosis with Rhipicephalus sanguineus tick infestation. The therapy provided includes symptomatic therapy, causative therapy, and supportive therapy. Diphenhydramine HCl injection 1.1 mL, intramuscularly. The antibiotic doxycycline is given at a dose of 10 mg/kg, once a day for 28 days. Sangobion was given to reduce clinical symptoms, which is anemia and thrombocytopenia. Dog was bathed with a Tick and Flea shampoo which contains insecticides (Pyrethrin and Piperonyl). The evaluation was carried out after the antibiotics were finished, based on the owner's statement, the condition of the case dog was healthy, no longer scratching and falling hair, and the tick infestation had disappeared. It is recommended to eradicate the vector (Rhipicephalus sanguineus) in the environment where animals live. This is done to prevent recurrent infections from Ehrlichia.
