efficacy of milbemycin oxime afoxolaner chewable tablets nexgard spectra against Capillaria aerophila and Capillaria boehmi in naturally infected dogs
Parasites & Vectors, 2021Co-Authors: Angela Di Cesare, Simone Morelli, Giulia Morganti, Giulia Simonato, Fabrizia Veronesi, Mariasole Colombo, Michele Berlanda, Wilfried Lebon, Matilde Gallo, Frederic BeugnetAbstract:BACKGROUND Capillaria aerophila and Capillaria boehmi parasitize the respiratory system of wild and domestic carnivores. Capillaria aerophila inhabits the trachea and bronchi of dogs and cats, while C. boehmi affects the nasal cavities and sinuses of dogs. In dogs the infection may be subclinical or characterized by varying respiratory distress. METHODS The present study evaluated the efficacy of an oral formulation containing milbemycin oxime and afoxolaner (NEXGARD SPECTRA®) in dogs naturally infected with C. aerophila and/or C. boehmi from three enzootic areas of Italy. Dogs were enrolled pending fecal examination and molecular confirmation of respiratory capillarioses. Dogs were allocated in two groups: Group 1 (G1, 25 dogs), treated with a negative control product with no anthelmintic activity (afoxolaner, NEXGARD®), and Group 2 (G2, 26 dogs), treated with NEXGARD SPECTRA®. At the day of treatment administration (Day 0), all dogs were clinically examined. Dogs were again subjected to clinical and fecal examinations at Days 28 (± 4) and 56 (± 2). The primary criterion for treatment efficacy was the reduction of fecal Capillaria egg counts in G2 compared with G1. The regression of/recovery from baseline clinical signs was considered as a further efficacy criterion. RESULTS Percentage reduction of fecal Capillaria egg counts in the NEXGARD SPECTRA® group compared to the control group was > 97% on Day 28 and 100% on Day 56, respectively (p < 0.05 for both time points). Twelve of the 13 dogs in the NEXGARD SPECTRA® group with respiratory signs prior to treatment were free of clinical signs at the end of the study. Conversely, the six control group dogs with respiratory signs prior to treatment remained symptomatic. CONCLUSIONS Results of the present study showed that NEXGARD SPECTRA® was safe and highly efficacious in the reduction of C. aerophila and C. boehmi eggs after one treatment with a complete reduction of the egg output after the second administration associated with a recovery from respiratory signs.

single and mixed feline lungworm infections clinical radiographic and therapeutic features of 26 cases 2013 2015
Journal of Feline Medicine and Surgery, 2017Co-Authors: Paolo Emidio Crisi, Donato Traversa, Angela Di Cesare, Giovanni Aste, Elettra Febo, M Vignoli, Domenico Santori, Alessia Luciani, Andrea BoariAbstract:Objectives The aim of this study was to retrospectively describe clinical, radiographic and therapeutic features of feline lungworm infection. Methods Medical records of cats with lungworm diagnosis, thoracic radiography and without concurrent diseases between 2013 and 2015 were reviewed. Collection of data included physical examination, haematology, serum biochemistry, therapy with a variety of anthelmintics and outcomes. Results Thirty-seven records were recovered and 26 were included in the study. Single infections by Aelurostrongylus abstrusus (n = 15), Troglostrongylus brevior (n = 3) and Capillaria aerophila (n = 1) and coinfections by T brevior/ A abstrusus (n = 6) and T brevior/ C aerophila (n = 1) were diagnosed. The most common respiratory signs were coughing (n = 12), increased vesicular sounds (n = 10), dyspnoea (n = 9), such as laboured breathing, orthopnoea or open-mouth breathing, and tachypnoea (n = 6). Two cats were subclinically infected. The most common laboratory abnormality was anaemia (n = 7). Radiographic patterns recorded were interstitial (n = 24), bronchial (n = 21), alveolar (n = 10) and vascular (n = 2). Twenty-five cats had a complete recovery within 2-6 weeks of therapy. One kitten died 7 days after the diagnosis. Conclusions and relevance Lungworms should always be included in the differential diagnosis in cats living in endemic areas and presenting with respiratory signs and radiographic abnormalities. A copromicroscopic examination should be considered as the first diagnostic step for all cats at risk of lungworm infections. In most cases, timely therapy with a variety of anthelmintics guarantees recovery.

Zoonotic parasites in feces and fur of stray and private dogs from Italy
Parasitology Research, 2015Co-Authors: Barbara Paoletti, Donato Traversa, Roberto Bartolini, Raffaella Iorio, Alberto Berardinis, Romolo Salini, Angela Di CesareAbstract:The present study evaluated the occurrence of zoonotic parasites in feces and on fur of stray and private dogs living in Italy. Individual fecal samples collected from 117 and 385 kenneled (i.e., rescue shelter) and privately owned dogs, respectively, were examined by conventional copromicroscopy. Samples positive for Giardia duodenalis and Cryptosporidium spp. were subjected to further genetic characterization. Additionally, 174 fur samples of private and kenneled dogs living in the same area, 27 of which were also subjected to copromicroscopical examinations, were examined for the presence and viability of parasite elements. Out of 502 fecal samples, forty-one (8.2 %) scored positive for G. duodenalis cysts while one (0.2 %) for Cryptosporidium oocysts. Nine private dogs were molecularly positive for G. duodenalis assemblage C (n. 7), assemblage D (n. 1), and assemblages C + D (n. 1), while 11 kenneled dogs were positive for assemblage C (n. 8), assemblage D (n. 1), and assemblages C + D (n. 2). Cryptosporidium spp. were identified as C. canis in a private dog. One hundred and seventy-two dogs (34.3 %), i.e., 92 private and 80 kenneled, were positive for zoonotic nematodes: Toxocara canis (6.6 %), Ancylostoma caninum (6.8 %), and Capillaria aerophila (0.6 %). Unviable eggs of Toxocara spp. were found on the hair of five (2.9 %) private dogs. The present findings indicate that canine feces from both private and kenneled animals may contain zoonotic parasites and may be a potential risk for humans and other animals, especially when they contaminate the environment. The role of dog fur as source of human infections should be further investigated.

efficacy and safety of imidacloprid 10 moxidectin 1 spot on formulation in the treatment of feline infection by Capillaria aerophila
Parasitology Research, 2012Co-Authors: Donato Traversa, Angela Di Cesare, Giuseppe Castagna, Piermarino Milillo, Emanuela Di Giulio, Roland Schaper, Gabriele Braun, Beate Lohr, Fabrizio Pampurini, Katrin StrubeAbstract:The nematode Capillaria aerophila (Trichuroidea, Trichuridae) affects the respiratory system of cats and other animals and occasionally of human beings. Infected cats may show bronchovesicular sounds, inflammation, sneezing, wheezing and, chronic cough and, sometimes, bronchopneumonia and respiratory failure. The present study evaluated the efficacy and safety of the antiparasitic spot-on formulation containing imidacloprid 10 %/moxidectin 1 % (Advocate®, Bayer Animal Health) in the treatment of natural feline infection with the lungworm C. aerophila. The efficacy of Advocate® administered once was tested on days 7 ± 1 and 11 ± 1 following treatment at day 0 and compared to faecal egg counts on days −6 ± 1 and −2 ± 1. Overall, 36 cats treated either with Advocate® (treatment group, n = 17 cats) or left untreated (control group, n = 19 cats) were included in the study. Geometric means of faecal egg counts values in eggs per gram of faeces were 124.03 prior to treatment and 0.26 posttreatment in treatment group, while 107.03 and 123.94 pre- and posttreatment in the untreated cats. Post-baseline egg counts showed a 99.79 % reduction in Advocate®-treated animals in comparison with cats which were left untreated. Also, treated cats showed no adverse events. This trial demonstrated that Advocate® spot-on formulation is safe and effective in the treatment of feline lung capillariosis caused by C. aerophila.

Feline gastrointestinal parasitism in Greece: emergent zoonotic species and associated risk factors
Parasites & Vectors, 2018Co-Authors: Isaia Symeonidou, Athanasios I. Gelasakis, Konstantinos Arsenopoulos, Athanasios Angelou, Frederic Beugnet, Elias PapadopoulosAbstract:Background Feline gastrointestinal parasitism constitutes an issue of concern for veterinarians since parasites are widespread and affect animals’ health and welfare. Furthermore, some of these pathogens have zoonotic potential. To provide detailed data on the current epizootiology of feline endoparasitism, a multicentric survey was conducted during 2016. Methods Faeces from 1150 cats were collected from all regions of Greece and examined by sedimentation and flotation techniques. Possible risk factors including gender, age, ownership status, living conditions and co-infections with other parasites were assessed using binary regression models for each one of the most prevalent parasites. Results The overall gastrointestinal parasite prevalence in cats was 50.7%. The study population consisted of cats of both sexes, different age groups, ownership status and living conditions. A total of 10 gastrointestinal parasitic species were detected and up to 5 different parasites were isolated in the same faecal sample. The most frequently identified parasites were Toxocara cati ( n = 278; 24.2%), followed by Cystoisospora spp. ( n = 189; 16.4%), Ancylostomatidae ( n = 186; 16.2%), Aelurostrongylus abstrusus ( n = 40; 3.5%), Giardia spp. ( n = 26; 2.3%), Joyeuxiella pasqualei ( n = 14; 1.2%), Capillaria aerophila ( n = 8; 0.7%), Dipylidium caninum ( n = 3; 0.2%), Toxascaris leonina ( n = 2; 0.1%) and Troglostrongylus brevior ( n = 2; 0.1%). The occurrence of co-infections was 11.6%. Concerning risk factors, the likelihood of T. cati infection was higher for female cats living outdoors and for cats being infected with Cystoisospora spp. In the same frame, young, stray, male and free of A. abstrusus cats were more likely to be infected with Cystoisospora spp. Correspondingly, stray, infected with Giardia spp. but free of Cystoisospora spp. cats were more likely to be infected with Ancylostomatidae. Regarding A. abstrusus infection, a higher probability was reported for cats living outdoors and for cats free of Cystoisospora spp., while Giardia spp. infections were more common in young and co-infected with Ancylostomatidae animals. Conclusions The prevalence of parasitized cats in Greece was high and thus consideration should be paid to control the risk factors, to implement targeted preventive antiparasitic treatments and educate cat owners on the value of prevention for the health and welfare of their cats.

Six-month field efficacy and safety of the combined treatment of dogs with Frontline Tri-Act® and NexGard Spectra®
BMC, 2018Co-Authors: Jessica M. Abbate, Frederic Beugnet, Ettore Napoli, Francesca Arfuso, Gabriella Gaglio, Salvatore Giannetto, Lenaig Halos, Emanuele BriantiAbstract:Abstract Background Safety and efficacy of the combined monthly use of spot-on fipronil 6.76% w/v / permethrin 50.48% w/v (Frontline Tri-Act®) and chewable tablets of afoxolaner 1.9% w/w / milbemycin oxime 0.4% w/w (NexGard Spectra®) in dogs was evaluated in a field study over a period of 6 months. Methods Forty-one healthy dogs living in highly endemic area for canine leishmaniosis and other canine vector borne diseases (VBD) were included in the study at the beginning of the Leishmania transmission season. Sixteen dogs were pet dogs living each in a single household; twenty-five dogs were hunting dogs living in three kennels. At inclusion, the dogs were ELISA (rapid test) negative for antibodies to Anaplasma, Borrelia, Ehrlichia, and for antigens of Dirofilaria. The dogs were also negative for blood microfilariae at the Knott’s test, and no clinical or haematological abnormalities were observed. Of the included dogs, six hunting, apparently healthy, dogs were ELISA (rapid test) positive to Leishmania, and some were naturally infected by gastrointestinal nematodes (58.5%) and/or infested by fleas (58.5%) and ticks (9.8%). All the included dogs were treated at Days 0, 28, 56, 84, 112 and 140, and followed-up for efficacy until the study end (Day 168). Results No adverse events related to the two products, nor skin reactions, general signs, or changes in the haematological profile, were observed during the study. At Day 14, anthelminthic efficacy was 100% for Toxocara canis, Toxascaris leonina and Capillaria aerophila, while few hunting dogs were still shedding eggs of Trichuris vulpis (1/25 hunting dog) and Ancylostomatidae (9/25 hunting dogs). All pet dogs were nematode free at the end of the study. Hunting dogs were free of roundworms and whipworms. Twenty-four hours after the first treatment, 95.8% of the ectoparasite infested dogs were free from fleas and ticks. Ectoparasites were significantly controlled during the 6-month study period, with 100% efficacy on both fleas and ticks from Day 56 to Day 168. Blood and serum samples collected on Day 168 were tested for vector-borne pathogens using same methods of the inclusion and no new seroconversions or circulating blood microfilariae were observed. Conclusions Concomitant use of Frontline Tri-Act® and NexGard Spectra® in dogs for six months was well tolerated. The combination was effective in controlling fleas, ticks, gastro-intestinal nematodes, and neither new seroconversion to the tested vector-borne pathogens nor blood microfilariae were detected in treated dogs at the end of the study

Mixed trichuroid infestation in a dog from Italy
Parasites & Vectors, 2012Co-Authors: Angela Di Cesare, Giuseppe Castagna, Domenico Otranto, Silvana Meloni, Donato TraversaAbstract:Background Capillaria aerophila , Capillaria boehmi and Trichuris vulpis are trichuroid nematodes affecting wild and companion animals all over the World. The canine intestinal whipworm, T. vulpis , is the most common and well- known in veterinary practice, whereas the respiratory C. aerophila and C. boehmi have been rarely reported in pets as a likely consequence of overlapping morphometric and morphological features of the eggs, which impair a correct etiological diagnosis. Findings In December 2011, a mixed infestation by T. vulpis , C. aerophila and C. boehmi was diagnosed in an asymptomatic dog living in central Italy. Morphometric and morphological findings and pictures of the eggs found at the copromicroscopic analysis are herein reported. Conclusions The present work demonstrates that when trichuroid eggs are found in a faecal sample from a dog, a careful morphological and morphometric analysis of individual parasite elements is mandatory. Key diagnostic features (i.e., size, wall surface pattern and aspects of plugs) should be carefully examined when eggs with overlapping shape and appearance are detected. In conclusion, given the importance in clinical practice of canine trichuroids and the zoonotic potential of C. aerophila , these nematodes should be included into the differential diagnosis of intestinal and respiratory parasitoses of dogs by a thorough microscopic analysis of all trichuroid ova present in microscopic fields.

molecular detection of Capillaria aerophila an agent of canine and feline pulmonary capillariosis
Journal of Clinical Microbiology, 2012Co-Authors: Angela Di Cesare, Giuseppe Castagna, Domenico Otranto, Silvana Meloni, Piermarino Milillo, Maria Stefania Latrofa, Barbara Paoletti, Roberto Bartolini, Donato TraversaAbstract:ABSTRACT Capillaria aerophila, a trichuroid nematode causing pulmonary infections in wild and domestic carnivores, is occasionally and potentially poorly recognized in infections of humans due to clinicopathological mimicry and a lack of accurate, robust laboratory diagnostics. The present work evaluated the efficiency of a DNA-based assay amplifying a partial cytochrome c oxidase subunit 1 (cox1) gene of C. aerophila in the diagnosis of lung capillariosis. Fecal samples from 34 dogs and 10 cats positive at parasitological examination for C. aerophila and other endoparasites (i.e., other lungworms, whipworms, roundworms, hookworms, tapeworms, and/or coccidia) and from 44 animals negative for C. aerophila but positive for other endoparasites were molecularly examined. Of the 44 samples positive for C. aerophila at copromicroscopy, 43 scored positive (i.e., 33/34 dogs and 10/10 cats) in seminested PCR, resulting in a sensitivity of 97 to 100%. Samples that were copromicroscopy negative for C. aerophila although positive for other endoparasites never produced a PCR product or nonspecific amplicons. The specific PCR amplification of C. aerophila (i.e., specificity of 100%) was confirmed by a nucleotide sequence analysis of the cox1 amplicons. The potential implications of the molecular diagnosis of lung capillariosis are discussed.

efficacy of milbemycin oxime afoxolaner chewable tablets nexgard spectra against Capillaria aerophila and Capillaria boehmi in naturally infected dogs
Parasites & Vectors, 2021Co-Authors: Angela Di Cesare, Simone Morelli, Giulia Morganti, Giulia Simonato, Fabrizia Veronesi, Mariasole Colombo, Michele Berlanda, Wilfried Lebon, Matilde Gallo, Frederic BeugnetAbstract:BACKGROUND Capillaria aerophila and Capillaria boehmi parasitize the respiratory system of wild and domestic carnivores. Capillaria aerophila inhabits the trachea and bronchi of dogs and cats, while C. boehmi affects the nasal cavities and sinuses of dogs. In dogs the infection may be subclinical or characterized by varying respiratory distress. METHODS The present study evaluated the efficacy of an oral formulation containing milbemycin oxime and afoxolaner (NEXGARD SPECTRA®) in dogs naturally infected with C. aerophila and/or C. boehmi from three enzootic areas of Italy. Dogs were enrolled pending fecal examination and molecular confirmation of respiratory capillarioses. Dogs were allocated in two groups: Group 1 (G1, 25 dogs), treated with a negative control product with no anthelmintic activity (afoxolaner, NEXGARD®), and Group 2 (G2, 26 dogs), treated with NEXGARD SPECTRA®. At the day of treatment administration (Day 0), all dogs were clinically examined. Dogs were again subjected to clinical and fecal examinations at Days 28 (± 4) and 56 (± 2). The primary criterion for treatment efficacy was the reduction of fecal Capillaria egg counts in G2 compared with G1. The regression of/recovery from baseline clinical signs was considered as a further efficacy criterion. RESULTS Percentage reduction of fecal Capillaria egg counts in the NEXGARD SPECTRA® group compared to the control group was > 97% on Day 28 and 100% on Day 56, respectively (p < 0.05 for both time points). Twelve of the 13 dogs in the NEXGARD SPECTRA® group with respiratory signs prior to treatment were free of clinical signs at the end of the study. Conversely, the six control group dogs with respiratory signs prior to treatment remained symptomatic. CONCLUSIONS Results of the present study showed that NEXGARD SPECTRA® was safe and highly efficacious in the reduction of C. aerophila and C. boehmi eggs after one treatment with a complete reduction of the egg output after the second administration associated with a recovery from respiratory signs.

Parasites & Vectors, 2021Co-Authors: Angela Di Cesare, Simone Morelli, Giulia Morganti, Giulia Simonato, Fabrizia Veronesi, Mariasole Colombo, Michele Berlanda, Wilfried Lebon, Matilde Gallo, Frederic BeugnetAbstract:Capillaria aerophila and Capillaria boehmi parasitize the respiratory system of wild and domestic carnivores. Capillaria aerophila inhabits the trachea and bronchi of dogs and cats, while C. boehmi affects the nasal cavities and sinuses of dogs. In dogs the infection may be subclinical or characterized by varying respiratory distress. The present study evaluated the efficacy of an oral formulation containing milbemycin oxime and afoxolaner (NEXGARD SPECTRA®) in dogs naturally infected with C. aerophila and/or C. boehmi from three enzootic areas of Italy. Dogs were enrolled pending fecal examination and molecular confirmation of respiratory capillarioses. Dogs were allocated in two groups: Group 1 (G1, 25 dogs), treated with a negative control product with no anthelmintic activity (afoxolaner, NEXGARD®), and Group 2 (G2, 26 dogs), treated with NEXGARD SPECTRA®. At the day of treatment administration (Day 0), all dogs were clinically examined. Dogs were again subjected to clinical and fecal examinations at Days 28 (± 4) and 56 (± 2). The primary criterion for treatment efficacy was the reduction of fecal Capillaria egg counts in G2 compared with G1. The regression of/recovery from baseline clinical signs was considered as a further efficacy criterion. Percentage reduction of fecal Capillaria egg counts in the NEXGARD SPECTRA® group compared to the control group was > 97% on Day 28 and 100% on Day 56, respectively (p < 0.05 for both time points). Twelve of the 13 dogs in the NEXGARD SPECTRA® group with respiratory signs prior to treatment were free of clinical signs at the end of the study. Conversely, the six control group dogs with respiratory signs prior to treatment remained symptomatic. Results of the present study showed that NEXGARD SPECTRA® was safe and highly efficacious in the reduction of C. aerophila and C. boehmi eggs after one treatment with a complete reduction of the egg output after the second administration associated with a recovery from respiratory signs.
