RESUMEN

The trend of feeding dogs and cats with raw pet food claiming health benefits poses health concerns due to the occurrence of pathogenic bacteria. High pressure processing (HPP) allows the non-thermal inactivation of microorganisms, preserving the nutritional characteristics with minimal impact on organoleptic traits of food. The present study aimed to evaluate and model the effect of HPP application (450-750 MPa for 0-7 min) on the inactivation of Salmonella, endogenous microbiota and colour of raw pet food formulated with different concentrations of lactic acid (0-7.2 g/kg) as natural antimicrobial. Additionally, the effect of a subsequent frozen storage of pressurized product was assessed. Salmonella inactivation ranged between 1 and 9 log, depending on the combination of conditions. According to the polynomial model obtained, the effect of pressure was linear, while a quadratic term was also included for holding time (depicting the occurrence of a resistant tail at ca. 4-6 min). The effect of lactic acid was dependent on the pressure level, being most relevant for treatments below 600 MPa. Frozen storage after HPP prevented the pathogen recovery and caused a further Salmonella inactivation enhanced by lactic acid in most of the treatments. Endogenous microbial groups were significantly reduced by HPP to below the detection level in several conditions. In general, little effect of HPP on the instrumental colour parameters was observed, except for a slight increase in lightness, which was hardly appreciable from visual observation. High pressure processing emerges as a relevant technology for the control of Salmonella spp. and to manage the microbiological safety of raw pet food. The mathematical model can be used as decision support tool to design safer raw pet food, while keeping the desired freshness appearance of the products.

RESUMEN

Invasive alien mammals cause huge adverse ecological impact on human society and natural ecosystems. Although studies have estimated economic costs of mammal invasions at regional scales, there is lacking the large-scale comprehensive assessment of currency costs for this taxon. Here, we estimated the economic cost of invasive alien mammals on a global scale using the most comprehensive global database compiling economic costs of invasive species (InvaCost). From 1960 to 2021, mammal invasions caused costs (summing damage costs and management costs) of US$ 462.49 billion to the global economy, while the total amount of robust costs reached US$ 52.49 billion. The majority of the total economic costs corresponded to damage costs (90.27 %), while only 7.43 % were related to management cost. Economic costs showed an increasing trend over time. The distribution of costs was uneven among taxonomic groups and regions, with the global total cost highly biasing toward to 5 species (European rabbit, Domestic cat, Black rat, Wild boar and Coypu), and North America reporting much higher costs (60.78 % of total economic costs) than other regions. The total costs were borne by agriculture, environment, authorities stakeholders and other sectors. Geographic and taxonomic biases suggested that total economic costs caused by invasive alien mammals were underestimated. Integrated research efforts are needed to fill in knowledge gaps in the economic costs generated by mammal invasions and to identify the drivers of the economic costs.

RESUMEN

Onchocerca lupi is a vector-borne filaroid which affects wild (i.e., wolves, coyotes) and domestic carnivores (i.e., dogs, cats), and occasionally humans. This nematode causes ocular damage due to the location of adult worms embedded in the eye connective tissues. Several human cases of onchocercosis by O. lupi have been reported in Europe, Asia, north Africa, and the USA where the infection thrives in dogs and less frequently in cats. In this study, we review clinical aspects of feline infestation by O. lupi, and report the first case of this onchocercid in a cat from Romania, showing a subconjunctival mass located at the medial canthus of the right eye; worms were surgically removed from the ocular nodule and morphologically and molecularly identified. Lesions were examined and characterized using histological procedures. Nematodes were identified as O. lupi based on their morphology at the direct observation as well as at the histological examination. Molecular and phylogenetic analysis confirmed the identification of this onchocercid, with the cox 1 sequence obtained clustering with those available in public repositories, including isolates from dogs and cats from Europe and USA. Despite the few reports available on the occurrence of this parasite on domestic cats, these felines are regarded as potential hosts of O. lupi in Portugal and USA. Moreover, the spread of feline ocular onchocercosis in Eastern Europe countries draw attention on the need of additional studies to confirm the potential vectors involved in its transmission cycle.

RESUMEN

Bartonella henselae is a zoonotic pathogen responsible for causing Cat Scratch Disease (CSD) and other clinical manifestations in humans. Domestic cats are the main reservoirs of this Bartonella species. Previous studies have suggested that certain genotypes of B. henselae seem to be more associated with human infections. The present study aimed to genotype B. henselae isolates from domestic cats' blood samples in the state of Goiás, midwestern Brazil. The association of quantitative real-time PCR (qPCR) based on the nuoG gene from Bartonella spp. of blood samples, before and after incubation in pre-enrichment liquid medium (BAPGM) and isolation on chocolate agar, showed a positivity frequency of 42% (42/100) for Bartonella spp. Twelve B. henselae isolates obtained on agar chocolate from six cats' blood samples (two isolates from each animal) were characterized by Multi-locus Sequencing Typing (MLST) and revealed to belong to Sequence Types ST1 and ST5. One of the cats (1/6) presented both STs, demonstrating that domestic cats can be coinfected with different variants of B. henselae. The STs detected in this study are distributed worldwide and have already been detected in humans with clinical manifestations of bartonellosis. This is the first report of the zoonotic variants ST1 and ST5 of B. henselae in domestic cats from Brazil.

RESUMEN

Acute pancreatitis is one of the most common diseases in dogs and cats, but diagnosis is challenging. The gold standard for diagnosis of pancreatitis is pancreatic biopsy, which has many limitations. As such, clinical diagnosis of pancreatitis based on a consistent clinical picture (eg, signalment, clinical signs, physical examination findings), supportive laboratory screening diagnostics, pancreatitis-specific laboratory testing, consistent imaging findings, and thorough diagnostic evaluation ruling out alternate differential diagnoses is most often used in clinical patients. Alternate differential diagnoses in patients presenting with clinical findings that might be consistent with pancreatitis may have secondary reactive pancreatitis, which mimics primary pancreatitis.

RESUMEN

The study aimed to describe the morphogenesis of the domestic cat uterine tube, from the primordial tubal segment of the paramesonephric duct (TsPD) to the mature organ. The specific aims included identifying differences in the rate and way of development of the layers in the wall of the infundibulum, the ampulla, and the isthmus. In the study we conducted light microscopic (LM) observations of the uterine tube wall, and analysis of 3D models, which were used for the first time to visualize the arrangement of the paramesonephric duct and highlight the pattern of the developing mucosal folds. The results revealed the two stages in the prenatal development of the domestic cat uterine tube. The first stage lasts from day 26-44 p.c. (post-conception) and includes the growth of the TsPD. It starts with formation of the TsPD's epithelial tubule in the mesenchyme of the anterior part of the mesonephros. The tubule, surrounded by mesenchyme, elongates posteriorly, and the TsPD can be divided into three sections according to their location and diameter, i.e., anterior, middle, and posterior. The first stage ends with the histodifferentiation of the mesenchyme into loose connective tissue and mucosa formation. The second stage lasts from approximately day 45-63 p.c. and comprises the formation of the proper layers in the uterine tube wall. The pace and pattern of layers' development are specific to each section of the uterine tube, as tissues first differentiate in its anterior part and then continue posteriorly. The mucosal folds appear after day 44 p.c. in the infundibulum, and they become long and branched by the end of the prenatal period. Then, approximately day 48 p.c., the single mucosal folds appear in the ampulla, and at the end, i.e., about day 63 p.c., they become visible in the isthmus. The 3D models revealed the unique spiral-shaped arrangement of the mucosal folds in the ampulla. The tunica muscularis starts to develop ca day 48-51 p.c. in the anterior part of the uterine tube. On approximately day 55 p.c., the circular muscle layer can be distinguished in the ampulla, while in the isthmus, it develops just before birth. The postnatal development of the infundibulum includes the formation of the labyrinth-like system of mucosal folds, whereas in the ampulla and isthmus, branched mucosal folds and the second longitudinal muscle layer develop postnatally. At the end of the prenatal period, the differences in the wall thickness between the individual segments of the uterine tube reflect the proper proportions of the uterine tube wall in the mature female.

RESUMEN

Canine cutaneous histiocytomas originate from Langerhans cells. Multiple histiocytomas are referred to as cutaneous Langerhans cell histiocytosis. Feline pulmonary Langerhans cell histiocytosis causes respiratory failure owing to extensive lung infiltration. Localized and disseminated histiocytic sarcomas usually arise from interstitial dendritic cells. Primary sites include spleen, lung, skin, brain (meninges), lymph node, bone marrow, and synovial tissues of limbs. An initially indolent form of localized histiocytic sarcomas, progressive histiocytosis, originates in the skin of cats. Hemophagocytic histiocytic sarcomas originates in splenic red pulp macrophages. Canine reactive histiocytoses (systemic histiocytosis and cutaneous histiocytosis) are complex inflammatory diseases with underlying immune dysregulation.

RESUMEN

Owners are often not aware that some common household products, medications, and plants are toxic to dogs and cats. Six cases of toxicoses due to ingestion of xylitol, amatoxin-containing mushrooms, anticoagulant rodenticide, zinc, vitamin D, and lily are presented with typical clinical and laboratory data findings. Changes in the laboratory data are explained in the context of the mechanism of action of the toxin and the organ systems affected.

RESUMEN

Canine and feline transfusions are life-saving procedures that have become increasingly common in veterinary medicine. Laboratory testing plays a vital role in transfusion medicine, particularly in the prevention and diagnosis of transfusion reactions. Laboratory tests should be used to screen donors for their general health and for the presence of any blood-borne pathogens. Pretransfusion blood typing and compatibility testing make immunologic reactions less likely, and commercial typing and crossmatching kits are now available. Appropriate diagnostic tests in the face of a potential transfusion reaction are important to tailor effective therapy.

RESUMEN

Feline leukaemia virus (FeLV) is a retrovirus that infects domestic and wild cats around the world. FeLV infection is associated with the development of neoplasms, bone marrow disorders and immunosuppression. Viral subgroups arise from mutations in the FeLV genome or from recombination of FeLV with ancestral endogenous retroviruses in the cat genome. The retroviral endogenisation process has allowed generation of a diversity of endogenous viruses, both functional and defective. These elements may be part of the normal functioning of the feline genome and may also interact with FeLV to form recombinant FeLV subgroups, enhance pathogenicity of viral subgroups, or inhibit and/or regulate other retroviral infections. Recombination of the env gene occurs most frequently and appears to be the most significant in terms of both the quantity and diversification of pathogenic effects in the viral population, as well as affecting cell tropism and types of disease that occur in infected cats. This review focuses on available information regarding genetic diversity, pathogenesis and diagnosis of FeLV as a result of the interaction between endogenous and exogenous viruses.

RESUMEN

Leishmaniosis is a high-burden vector-borne disease caused by Leishmania parasites that affect humans and other animals, including dogs and cats. Globalization is one of the main factors that largely contributes to the spread of leishmaniosis to non-endemic areas. A comprehensive review of scientific literature published between 2000 and 2021 was conducted to identify the epidemiological situation and clinical management of imported animal Leishmania infection and leishmaniosis as a fundamental step to better manage individual cases and traveler animal health from a global and One Health perspective. A total of 31 articles were selected, representing 1403 canine, and 25 feline imported cases. Canine and feline leishmanioses in non-endemic areas remain a challenge for veterinarians. Thus, diagnostic and management algorithms for veterinary clinical decision support are proposed. Increased surveillance of non-autochthonous cases, including relocated companion animals, could improve individual health, and mitigate the public and animal health risk of introducing Leishmania species into new areas.

RESUMEN

BACKGROUND: In humans, kidney injury molecule-1 (KIM-1) is a biomarker of acute kidney injury that can be quantified in urine. Preliminary investigation in cats with experimentally induced acute kidney injury showed that KIM-1 urine concentration correlated with kidney injury histopathology scores. A lateral flow assay (LFA) has recently become available for patient-side feline KIM-1 measurement. In vitro parameters of the assay have not yet been determined. The objectives of this study were to determine detection of KIM-1 in urine stored at different temperatures over time, to establish the linear range of the LFA, and to assess the intra-assay repeatability of measurements.  RESULTS: Ten urine samples with a range of KIM-1 concentrations were stored at room temperature (22o C), 4o C or -20o C, and tested with the LFA on days 0, 1, 2, 3, 7, 14, and 30. The concentration of KIM-1 in samples was not significantly different from the day 0 value, except one sample that had been stored for 30 days at room temperature yielded a significantly higher value. The assay results had a correlation coefficient of 0.922. The mean coefficient of variation for all samples was 15.7%. The slope of the curve of expected versus measured values in samples diluted two-fold nine times was 0.908, and results were linear over all dilutions. CONCLUSIONS: The LFA for feline KIM-1 yields consistent results from stored urine samples. These characteristics will allow for KIM-1 to be measured retrospectively if immediate testing is not feasible. Within assay precision was high, and linearity over 9 logs of dilution suggests suitability for a range of subclinical and clinical kidney injuries.

RESUMEN

Background: Cat allergen sensitization is a significant risk factor for allergic rhinitis and asthma. There are insufficient data on the preferences and attitudes of cat owners who have a cat allergy. Objective: To investigate the clinical characteristics of adults sensitized to cats and their association with cat ownership, and to assess owners' attitudes and behaviors. Methods: The study evaluated adult patients, ages between 19 and 74 years, who were sensitized to cat allergen as confirmed by skin-prick tests. The demographic and clinical data of the patients were obtained retrospectively from the hospital medical records system. A telephone interview with patients was conducted to evaluate whether they owned a cat and their attitudes toward cat allergy. A total of 143 patients who could not be reached by telephone or who refused to participate in the study were excluded. Patients were categorized into never owned a cat, early cat ownership (having a cat or cats in the first 2 years of the patient's life), and past and current cat ownership according to the status of patients at the time of their skin-prick test. Current cat owners were questioned whether they relinquished their cats and the presence and the degree of symptoms of both patients who relinquished their cats and patients who continued to live with their cats. Results: A total of 245 patients (women/men, 151/94) with a mean age of 31.56 ± 11.33 were included in the study. Eighty-three patients (33.9%) were current cat owners. After the skin-prick test, 54 cat owners (66.1%) continued living with their cats. Two-thirds of these owners were symptomatic, with 95% experiencing nasal symptoms. Only five of the patients with symptoms (14.3%) reported worsening symptoms. Any significant impact on symptoms was not determined with regard to number of cats, cat breeds, and precautionary measures. Conclusion: Cat allergen is a potential risk for public health. The clinician must engage in shared decision-making as to what type of environmental changes that the patient is willing to make and what treatment options, if any, they are ready to accept, recognizing that most patients will prefer to keep their cats.

RESUMEN

Canine ehrlichiosis and anaplasmosis are zoonotic tick-borne diseases with broad distribution. Advances in diagnostics have enhanced our understanding of the species of rickettsial organisms involved, their expanding geographic distribution, and their impact on the health of dogs, cats, and people. While clinical remission can be achieved with appropriate antimicrobial therapy, optimal treatment modalities for the elimination of infection remain somewhat uncertain. Protection through vaccines for ehrlichiosis or anaplasmosis remains elusive. This review provides practicing veterinarians with the most current information about the transmission, diagnosis, and management of ehrlichiosis and anaplasmosis in dogs and cats.

RESUMEN

Cytauxzoon felis is a hematoprotozoan parasite with a complex life cycle involving a tick-vector and a mammalian host. The mammalian hosts are all felidae but in the bobcat reservoir host, the parasite typically causes only a brief, self-resolving illness followed by a prolonged subclinical infection. In domestic cats, however, infection often leads to an acute febrile illness characterized by severe morbidity and mortality. Diagnosis is based on microscopic identification of parasites or molecular testing. Treatment for ill cats is expensive, difficult, and often unsuccessful. Prevention is quite possible and depends on avoidance of feeding by vector ticks.

RESUMEN

Spotted fever rickettsioses are important causes of emerging infectious disease in the United States and elsewhere. Rocky Mountain Spotted Fever, caused by R. rickettsii causes a febrile, acute illness in dogs. Because it circulates in peripheral blood in low copy number and because of the acute nature of the disease, dogs may test PCR and seronegative at the time of presentation. Therefore, therapy with doxycycline must be initiated and continued based on the clinician's index of suspicion. Combining PCR with serologic testing, repeat testing of the same pre-antimicrobial blood sample, and testing convalescent samples for seroconversion facilitates diagnosis. The prognosis can be excellent if appropriate antimicrobial therapy is begun in a timely fashion. It is well established that dogs are sentinels for infection in people in households and communities. Whether R. rickettsii causes illness in cats is not well established. The role of other spotted fever group rickettsia in causing illness in dogs and cats is being elucidated. Veterinarians should keep in mind that novel and well characterized species of SFG Rickettsia are important causes of emerging infectious disease. Veterinarians can play an important role in detecting, defining, and preventing illness in their canine patients and their human companions.

RESUMEN

Hemoplasma infections are erythrocytic infections in both cats and dogs but are more common, and more often associated with disease, in cats. Mycoplasma haemofelis is the most pathogenic species in cats, causing hemolytic anemia and fever in immunocompetent hosts, whereas Mycoplasma haemocanis usually only results in hemolytic anemia in splenectomized or immunocompromised dogs. Diagnosis is by polymerase chain reaction on blood samples because cytology is unreliable. Prompt treatment of clinical disease with supportive care and at least 2 weeks of doxycycline is usually successful. Transmission pathways have not been confirmed, but indirect, via vectors, and direct via bites/fights/predation are likely.

RESUMEN

Hepatozoon canis and Hepatozoon americanum are tick-borne infections of dogs transmitted by different tick species, with dissimilar geographic distributions, target organs, and clinical syndromes. H canis is transmitted mostly by the brown dog tick Rhipicephalus sanguineus sensu lato, affects hemolymphoid organs, is associated with anemia and other hematologic abnormalities, and is widely prevalent globally, whereas H americanum is transmitted by the Gulf Coast tick Amblyomma maculatum, causes severe myositis, and is an emerging parasite in the southern United States.
