New insights into the distribution of cardio-pulmonary nematodes in road-killed wild felids from Romania.

BACKGROUND: The population of wild felids is large and stable in Romania with many carnivore habitats being protected. Felids can be infected with a wide variety of cardio-pulmonary nematodes and can act as reservoirs of infection for domestic cats. The aim of this study was to evaluate the distribution and species diversity of cardio-pulmonary nematodes in wild felids from Romania. METHODS: A total of 54 wild felids (7 Lynx lynx and 47 Felis silvestris) were legally collected from different locations in Romania and analysed by complete parasitological necropsy. The entire respiratory tract was longitudinally opened and checked for the presence of nematodes. Detected nematodes were collected and morphologically identified to species level. RESULTS: Two Eurasian lynxes and 29 European wildcats were positive for cardio-pulmonary nematodes. Eurasian lynxes were infected with two species of cardio-pulmonary nematodes, Eucoleus aerophilus and Troglostrongylus brevior, while in wildcats the dominant parasite was E. aerophilus (34.0%) followed by Angiostrongylus chabaudi (23.4%) and T. brevior (14.9%). Dirofilaria immitis and Aelurostrongylus abstrusus were each detected in two wildcats (4.3%). CONCLUSIONS: The present study expanded the epidemiological knowledge on felid cardiopulmonary nematodes in Romania. We confirmed the presence of A. abstrusus in wildcats and a patent infection with T. brevior in Eurasian lynx.

Aerobic Isolates from Gestational and Non-Gestational Lactating Bitches (Canis lupus familiaris).

Mastitis is a complex and well-defined mammary gland pathology, and an emergency in bitches. In dogs, its prevalence is about 1% of all reported diseases and about 5.3% of all reproductive pathologies. Lactating bitches are naturally prone to developing mastitis since puppies can easily overstimulate the epidermal layer of nipples during feeding, facilitating bacterial colonization of the glands. This study aimed to describe the aerobic bacterial flora isolated from milk samples derived from a cohort of patients (n = 87) diagnosed with clinical mastitis (n = 29), subclinical mastitis (n = 17) and healthy mammary glands (n = 46). All of the patients underwent a gynecology consultation to diagnose mammary gland afflictions; physical examination results were coupled with traditional hematological findings. The milk samples were plated on specific microbiological media for bacterial isolation. Among the 162 milk samples analyzed, 93.2% (151/162) had a positive microbiological result, while 6.8% (11/162) were sterile. The bacteriological profile of the milk samples showed 47 different species. The most common bacterial families detected in healthy bitches and bitches with subclinical and clinical mastitis were the Staphylococcaceae, Enterobacteriaceae and Enterococcaceae families. The results indicated that half of the isolated bacteria are novel findings in dogs and that some of them are normal components of human milk.

Milk C-reactive protein in canine mastitis.

Presence of mastitis in lactating bitches can become life threatening for both the bitch and pups. The aim of the present study was to evaluate a possible utility of C-reactive protein (CRP) in both milk and serum for canine mastitis diagnosis. Our study showed that milk CRP levels ranged between 0.1 and 4.9µg/mL and from 0.3 to 40.0µg/mL in healthy and diseased bitches (P<0.01), respectively, while serum CRP levels ranged between 2.0 and 8.6µg/mL and between 0.3 and 162.3µg/mL in healthy and diseased bitches (P<0.01), respectively. Milk and serum CRP levels were higher in both clinical and subclinical mastitis when compared with healthy controls (P<0.05 in all cases). However, no significant differences were recorded in CRP concentrations between clinical and subclinical cases. Based on these results, it could be concluded that serum and milk CRP could be useful in order to diagnose canine mastitis.
