Feline Heartworm in Clinical Settings in a High Canine Prevalence Area

Frontiers in Veterinary Science (2022)

Bruno Alberigi Diefrey Ribeiro Campos Aline Serricella Branco Alexandre José Rodrigues Bendas Rodrigo Pereira Brum

Heartworm (HTW) infection in cats is associated with persistent pulmonary pathology, even when clinical signs are absent. Treatment options for cats are limited once infected, making prevention an important topic for discussion with cat owners. In Brazil, tests to detect feline HTW infections are unavailable, likely leading to an underestimation of its impact on the wellbeing of cats. The present study investigated the seroprevalence of HTW antigen in cats living in an area with high canine HTW prevalence and investigated risk factors and clinical signs associated with HTW disease in cats from Rio de Janeiro, Brazil. Clinical examinations were conducted, and serological evaluations performed with a point-of-care test (SNAP® Feline Triple® Test, IDEXX Laboratories, Inc.). A total of 586 cats were examined. The HTW antigen seroprevalence was 1.2%. Heartworm positive results were significantly associated with vomiting and abnormal lung sounds. Results from this study indicate that cats residing in areas of high canine HTW prevalence should have HTW disease as a differential diagnosis when presenting with compatible clinical signs. Veterinarians should prioritize client education and promote regular use of effective prophylaxis to protect feline health.

ABSTRACT: This retrospective study evaluated the impact of the clinical presentation of pyometra on the morbidity and mortality of the affected bitches. The medical records of 47 bitches surgically treated for pyometra between May and December 2017 were evaluated. The admission data were analyzed to classify the animals according to the clinical presentation of pyometra, presence of systemic inflammatory response syndrome (SIRS) and organic dysfunctions (cardiovascular, neurological, renal, and hemostatic). The outcomes were recorded for up to 14 days. The overall mortality rate was 13%. Open and closed pyometra were identified in 62% (n= 29) and 38% (n= 18) of the cases, respectively. The SIRS was present in 44 (94%) bitches, and 27 (57%) had at least one organ dysfunction. The most prevalent dysfunction was hemostatic, followed by neurological, cardiovascular, and renal dysfunction. The clinical presentation of pyometra and the presence of SIRS did not correlate with each other, or with the presence of organ dysfunction and mortality. However, cumulative organ dysfunction (r=0.532, P=<0.001) and the presence of neurological (r= -0.371; P=0.012) and renal dysfunction (r=0.303; P=0.041) were correlated with mortality. Thus, the identification of organ dysfunction through physical examination and routine laboratory analysis proved to be more effective in identifying and predicting the critically ill patients than the SIRS criteria or clinical presentation of the disease.

Este levantamento de dados teve como objetivo identificar as principais irregularidades ocorridas em açougues localizados no município de Nilópolis, Rio de Janeiro para reconhecer o papel do médico veterinário na atuação da vigilância sanitária. O levantamento demonstrou a situação do comércio de carnes e suas principais irregularidades no ano de 2019. Foi também demonstrado quais mecanismos à administração municipal utiliza para manter a sanidade e como tais ações se transferem para o encargo da vigilância sanitária e do médico veterinário, tendo sido relatado com embasamento legal a atuação do profissional de saúde animal neste campo e como os aspectos econômicos e sociais estão atrelados ao consumo da carne e sua venda, que posteriormente serão fiscalizados e caso necessário regulamentados pela atuação do agente de saúde pública. Os dados da resenha aqui apresentada foram concedidos pela Secretaria Municipal de Saúde e também pela Secretaria Municipal de Fazenda e levantados na plataforma REGIN utilizando a base de dados da junta comercial do estado do Rio de Janeiro (2020). São apresentados dados que demonstram os estabelecimentos cadastrados por categorias e sua média de óbice, assim como as principais categorias onde tais óbices ocorreram e como eles implicam da legislação vigente no ano de 2019. É importante salientar também a demonstração dos dias para resolução de tais erros e a porcentagem de aderimento por parte do empreendedor, onde foi possível observar que houve avanços significativos visto que, de todos os problemas relatados os mais impactantes foram os referentes a manipulação de alimentos de maneira incorreta e falta de organização ou limpeza nos estoques. Após análises dos dados, foi possível observar que a profilaxia e a inspeção são os melhores caminhos para o desempenho de qualidade e que o trabalho da vigilância sanitária é fundamental para a manutenção da saúde pública. É válido demonstrar também a grande importância do médico veterinário na fiscalização municipal em prol da saúde populacional tornando, assim, o âmbito social melhor e também mais seguro..

Efficacy of semi-annual therapy of an extended-release injectable moxidectin suspension and oral doxycycline in Dirofilaria immitis naturally infected dogs

Parasites & Vectors (2020)

Bruno Alberigi Júlio Israel Fernandes Jonimar Pereira Paiva Flavya Mendes-de-Almeida Fabiana Batalha Knackfuss

Abstract Background Dirofilaria immitis is a life-threatening nematode spreading globally. Arsenical treatment is currently recommended for removal of adult worms. However, arsenical treatment is not available in some countries, and there are dogs that cannot tolerate the rapid kill of adult worms; therefore, alternative adulticide slow-kill treatments are needed. Criticisms against the use of these alternative protocols include the potential for allowing disease to progress and for the development of ML-resistant worms. Methods The efficacy of a protocol that includes semi-annual doses (i.e. every 6 months) of commercially available extended-release injectable moxidectin suspension (ProHeart ® SR-12) with 30-day oral administration of doxycycline was studied in 20 dogs with naturally occurring D. immitis infections. Each dog received treatment with ProHeart ® SR-12 (0.5 mg moxidectin/kg) by subcutaneous injection and oral doxycycline (10 mg/kg/bid × 30 days) every 6 months until two consecutive negative antigen test results were obtained. Pulmonary and cardiac evaluations were performed by radiographic and echocardiographic parameters. Physical examinations, complete blood counts, clinical chemistry profiles, microfilariae and antigen tests were performed periodically. Results At enrollment, all dogs were positive for D. immitis antigen and 18 were microfilaremic. On day 30, microfilaremia counts decreased, and all dogs became amicrofilaremic by day 150. On day 180, 11 dogs were antigen-negative, and 7 more became negative by day 360. The two remaining antigen-positive dogs converted to negative by day 540 or 810. All antigen tests performed 180 days after the first negative test were negative. There was no decline in cardiac performance of the dogs throughout the study. Overall, pulmonary clinical conditions, presence of worms by echocardiography, and enlargement of caudal and main pulmonary arteries improved after treatment. Physical examinations, complete blood count results, and clinical chemistry profiles were within normal reference values. Respiratory conditions were improved, no damage to the heart was observed, and the treatment protocol was well tolerated by the animals. Conclusions This alternative adulticide treatment was efficacious and well tolerated in naturally infected dogs. The injectable formulation provides the advantage of having veterinarians able to administer, monitor, and assess the efficacy and condition of the dog throughout the treatment and post-treatment periods.

Comparison of McMaster and Mini-FLOTAC techniques for the diagnosis of internal parasites in pigs

Revista Brasileira de Parasitologia Veterinária/Brazilian Journal of Veterinary Parasitology (2023)

Camila Souza Carvalho Class Priscila Alves Fialho Lêucio Câmara Alves Renato Luiz Silveira Maria Regina Reis Amendoeira

Abstract This purpose of this study was to compare the efficiency of the McMaster and Mini-FLOTAC quantitative techniques in the investigation of helminths in feces of pigs. An analysis was made of 74 fecal samples from pigs raised on family farms located in Rio de Janeiro, Brazil. These were analyzed by the Mini-FLOTAC and McMaster techniques in a solution of 1,200g/mL NaCl. This investigation revealed a superiority in the frequency of all helminths detected by Mini-FLOTAC, including Ascaris suum, Trichuris suis, strongyles and Strongyloides ransomi. The Kappa index revealed substantial agreement in all comparisons made in relation to the frequency of positive samples. However, significant statistical differences in the comparison of EPGs between McMaster and Mini-FLOTAC were observed for all nematodes (p ≤0.05). Higher values of Pearson’s linear correlation coefficient (r), between the techniques in relation to EPG were observed for A. suum and T. suis, differently from what was observed for strongyles and S. ransomi. Mini-FLOTAC proved to be a more satisfactory and reliable technique both for the diagnosis of parasites and for the determination of EPG in pig feces due to the larger size of its counting chambers, thus increasing the helminth egg recovery rates.

The Phylogenetic Characterization of Balantioides coli Isolated in the Pavlova Culture Medium Supplemented with Coconut Water and Animal Serum

Pathogens (2024)

Camila Souza Carvalho Class Laís Lisboa Corrêa Fabiana Batalha Knackfuss Maria Regina Reis Amendoeira Francisco Ponce‐Gordo

Balantioides coli is a ciliated protist that can cause dysentery in humans, pigs and nonhuman primates and may have the potential for zoonotic transmission. Its diagnosis is routinely performed through conventional parasitological techniques, and few studies have used culturing techniques to isolate it, applying molecular tools for the characterization of this protozoan. Thus, the objective of this study was to confirm B. coli diagnosis using molecular tools and to characterize the genetic variants of this parasite isolated from pigs kept on family farms in Brazil using three different culture media that differed in the serum added. Fecal samples from pigs were inoculated in Pavlova medium plus coconut water (PC), fetal bovine serum (PB) and horse serum (PH). Of the 127 samples positive for forms compatible with the phylum Ciliophora, 31 were selected for isolation. The most successful medium for isolation was PB 19/31 (61.3%), followed by PH 18/31 (58.1%) and PC 11/31 (35.5%). Of the nucleotide sequences generated, 20 were classified as genetic variant type B0, two as A1 and 15 as A0. The results indicated that PC, despite having allowed the isolation of B. coli for a short period, was not an adequate medium for the maintenance of this parasite in vitro, therefore requiring improvement.

The effect of post-hatch fasting for vitellin vesicle and diverticulum persistency in broilers (Gallus gallus)

Journal of Agricultural Sciences Research (2764-0973) (2022)

Elisabete Pereira Lemos Vianna Deila Maria Ferreira Scharra Ana Cláudia de Menezes Cruz Ingrid Lyrio Figueira Rodrigues Fabiana Batalha Knackfuss

An experiment was performed to study the fasting influence (12h, 24h, 48h and 72h) started immediately after hatching, until receiving the first food in 100 commercial "Cobb" hybrid linage lineage chicks, in the vitellin vesicle and diverticulum persistency.The chicks were reared until 58 days old and were slaughtered at the treatments finishing.The vitellin vesicles and diverticulum were analyzed and compared to the noted data regarding the weight gain, food consumption and food conversion, in the four experimental groups.According to the obtained results, it was observed that the chicks which received the initial food and water until 24 hours after the hatching showed better weight and food conversion indexes when compared to the other groups.It suggests a higher economy for the poultry farm comparatively to introducing the food at the first day of age, besides of showing a satisfactory time between the hatching and the transportation until the poultry farms.For the group receiving the early food, only the diverticulum was observed and, in most of times, small ones.It was observed that fasting had no influence in the vitellin diverticulum persistency, because in 100% of the samples it was present; however, the vitellin vesicle was influenced.

Clinical respiratory and radiographic abnormalities in dogs with spontaneous hypercortisolism.

PubMed (2024)

Diana do Amaral Mendonça Flávia Tavares Cristiano Chaves Pessoa da Veiga Fabiana Batalha Knackfuss Bruno Alberigi

The objective of this study was to characterize respiratory clinical signs, other than panting and respiratory distress, as well as thoracic radiographic abnormalities, in dogs with hypercortisolism. Although there have been case reports and studies evaluating the results of pulmonary scintigraphy, no studies have yet reviewed respiratory clinical signs and radiograph results in dogs with hypercortisolism. This study addresses this gap. A case series was evaluated and the dogs' clinical histories were obtained, including clinical signs and physical examination. Digital thoracic radiographs were analyzed to consider such parameters as the diameter of the main bronchi, lung patterns, and the size of the pulmonary trunk. The most common respiratory symptoms were snoring (61.9%), coughing (57.1%), and fatigue (52.4%). Physical examination revealed a high frequency of changes on lung auscultation (95.2%). The body condition score (BCS) was high in 95% of dogs and a significant correlation was observed between the presence of cyanosis and changes in lung auscultation, both of which present similar risk factors. Furthermore, body weight showed a moderate correlation with respiratory rate (RR = 0.571). Radiographic changes were evident in 47.5% of dogs, with the bronchial pattern being the most common (70%). Based on these results, it was observed that respiratory and radiographic abnormalities are frequent in dogs with spontaneous hypercortisolism and a high body condition score was relevant for exacerbating clinical respiratory signs, such as cyanosis and tachypnea.
