Cytomorphological characterization of lymphadenopathies in guinea pigs: study of 31 clinical cases

Antibacterial activity of plant extracts against Streptococcus equi subsp. zooepidemicus isolates from guinea pigs with lymphadenitis in Ecuador

“…All guinea pigs included in this study showed typical clinical signs of lymphadenitis, including hunched posture, abnormal gait, sunken abdomen, and enlargement or abscessation in lymph nodes of the neck [ 1 , 4 ].…”

“…The Caviidae family comprises approximately 23 species of South American rodents distributed in five genera. The guinea pig ( Cavia porcellus ) belongs to this family, is a mammal rodent native to the Andean region of Ecuador, Peru, Colombia, and Bolivia, domesticated 2500 to 3500 years ago [ 1 ]. It is crucial to produce meat with high nutritional value [ 2 ].…”

“…These diseases are caused by bacteria, viruses, and fungi that cause the death of the animals [ 2 ]. Among the most frequent diseases are respiratory diseases (frequently caused by Bordetella , Streptococcus , and adenovirus), salmonellosis, chlamydiosis, pneumonia, and lymphadenitis [ 1 , 4 , 5 ]. The latter is a severe and persistent chronic disease observed in guinea pigs.…”

“…These diverse modes of transmission highlight the versatility and adaptability of bacteria in their ability to infect and spread through different entry points. The most common conditions are respiratory and gastrointestinal [ 1 , 4 ]. The pathogens associated with lymphadenitis frequently include pyogenic bacteria Streptococcus sp., Staphylococcus sp., and Corynebacterium sp [ 2 , 5 , 9 ].…”

Cutaneous inflammatory lobular capillary haemangioma in a guinea pig (Cavia porcellus)

“…Clinical signs depend on location and may be vague. Definitive diagnosis requires histopathology and possibly immunohistochemistry (IHC) to differentiate between an inflammatory/infective process and benign or malignant neoplasm 7 . The information such as treatment and outcomes extracted from the published case reports is imprecise and further studies are required to better classify these lesions: most of these neoplasms are cured by complete surgical excision, but prognosis and survival time are difficult to estimate as there is a paucity of cases available in the literature 2,8 …”
