First PCR-confirmed feline hemoplasmosis case reported in Bosnia
Bottom line
A case report in Veterinary Sciences describes what the authors say is the first PCR-confirmed case of feline hemoplasmosis reported in Bosnia and Herzegovina, involving a 17-year-old spayed female cat with severe flea infestation, weakness, lethargy, fever, tachycardia, tachypnea, and marked pallor. The diagnosis was confirmed by PCR, which matters because current European guidance considers PCR the preferred diagnostic method for feline hemoplasma infections, given the limits of blood-smear cytology. The report also stands out for its long-term follow-up, adding clinical detail on treatment response and disease course in an older cat from a region with little published feline hemoplasma data. (abcdcatsvets.org)
Why it matters: For veterinary professionals, this is less about a single cat in Bosnia and more about diagnostic vigilance. Hemoplasmas are globally distributed and can cause feline infectious anemia, but clinical presentation is variable, and infection may be missed if anemia, fever, pallor, or flea burden are treated as nonspecific findings without molecular confirmation. The case also reinforces a practical point from ABCD guidance: cats with unexplained anemia or compatible signs, especially in the presence of ectoparasites, warrant PCR-based workups and aggressive flea control, even in countries where published feline hemoplasmosis data are sparse.

What to watch: Whether this first published case prompts broader surveillance, more PCR testing in cats with anemia in the Balkans, and additional reporting on regional hemoplasma prevalence and vector links. (pubmed.ncbi.nlm.nih.gov)
A new case report in Veterinary Sciences details what appears to be the first PCR-confirmed feline hemoplasmosis case published from Bosnia and Herzegovina, documenting the presentation and long-term follow-up of a 17-year-old spayed female cat. According to the report abstract, the cat presented with severe flea infestation, marked weakness and lethargy, fever, tachycardia, tachypnea, and pale mucous membranes, a constellation consistent with clinically significant hemoplasma-associated disease. The PCR confirmation is a key part of the story, because molecular testing is widely regarded as the diagnostic standard for feline hemoplasma infection. (abcdcatsvets.org)
The publication adds to a thin regional literature. Bosnia and Herzegovina has only recently begun to generate published molecular evidence of hemoplasma infection in animals, including a 2025 report describing the first molecular evidence of hemotropic mycoplasmas in goats from the country. In companion animals, other “first case” publications from Bosnia and Herzegovina, such as feline cryptococcosis, suggest a broader pattern: clinicians and researchers in the region are identifying conditions that may have been present but underdiagnosed because advanced diagnostics were not routinely documented in the literature. (pubmed.ncbi.nlm.nih.gov)
That context matters because feline hemoplasmosis is not a novel disease globally. Hemotropic mycoplasmas are recognized worldwide, and Mycoplasma haemofelis in particular is associated with hemolytic anemia in cats, while other species may be less pathogenic or act as coinfections. Reviews and guidelines note that transmission pathways are still not fully resolved, but arthropod exposure, especially fleas, remains a recurring epidemiologic concern. The Bosnia and Herzegovina case fits that pattern, with severe flea infestation featured prominently in the presentation. (pubmed.ncbi.nlm.nih.gov)
The report’s emphasis on PCR confirmation aligns with expert guidance from the ABCD, which states that PCR assays are the diagnostic method of choice for haemoplasma infection in cats. That recommendation reflects a longstanding problem in practice: blood-smear evaluation can miss infections because organism detection is inconsistent, while PCR can identify hemoplasma DNA with much greater sensitivity and specificity. Separate molecular diagnostics reviews also recommend PCR in cats with unexplained fever or anemia, and for screening feline blood donors. (abcdcatsvets.org)
Published guidance also provides useful treatment context. ABCD notes that doxycycline is commonly used for feline haemoplasmosis, often for about 28 days, but clinical improvement does not necessarily mean the organism has been fully cleared, and some cats may remain PCR-positive after treatment. The source abstract provided for this case mentions enrofloxacin among its tags, suggesting the report may also contribute to the smaller body of literature around alternative antimicrobial approaches and follow-up in persistent or complicated cases. Because I was not able to retrieve the full article text directly, that treatment interpretation should be read cautiously, but the long-term follow-up component is notable in itself.

Why it matters: For veterinarians, the bigger takeaway is that feline hemoplasmosis can still hide in plain sight, especially in older cats or those presenting with flea burden, pallor, lethargy, fever, or regenerative anemia. In lower-surveillance settings, a “first reported case” often signals a first confirmed diagnosis rather than a truly new pathogen arrival. That has practical implications for diagnostic algorithms, transfusion medicine, parasite control counseling, and communication with pet parents. It also underscores the value of pairing routine hematology with PCR when clinical suspicion remains high despite equivocal smear findings. (abcdcatsvets.org)
There’s also a public health and systems angle, even if the direct zoonotic relevance of feline hemoplasmas remains limited and not clearly established for routine companion animal practice. As regional veterinary centers publish more molecular case reports, they create a foundation for prevalence studies, vector surveillance, and more standardized diagnostic pathways. That can improve not just case recognition, but also antimicrobial stewardship by helping clinicians target treatment more confidently. (merckvetmanual.com)
What to watch: The next step is whether this case is followed by larger prevalence studies in cats in Bosnia and Herzegovina or neighboring countries, plus more data on species identification, coinfections, flea association, and post-treatment PCR outcomes. If that happens, this report may end up being less a one-off curiosity and more the starting point for a regional feline vector-borne disease surveillance story. (pubmed.ncbi.nlm.nih.gov)
