Bacterial species isolated from cats with lower urinary tract infection and their susceptibilities to cefovecin.

BACKGROUND: The aim of this study was to determine the bacterial species recovered from 61 cats with lower urinary tract infection (LUTI), and their susceptibility to cefovecin in vitro. RESULTS: The clinical signs and final clinical diagnosis for cats with confirmed LUTI were also reported. After physical examination of the cats, urine samples including ≥5-6 leucocytes in microscopic evaluation were cultured using bacteriological techniques. The isolates were identified by conventional microbiological methods and tested for in vitro susceptibility using the Kirby-Bauer disc diffusion method recommended by the Clinical Laboratory Standards Institute. Bacterial growth was observed in 16 of 61 urine samples. Antimicrobial susceptibility tests showed that 13 of 16 (81%) isolates were susceptible to cefovecin. The most frequently isolated bacterium from cats with signs of lower urinary tract infection, was Escherichia coli. CONCLUSION: Cefovecin was found to be effective in cats with LUTI. Because cefovecin is a new antimicrobial agent in veterinary medicine, there are only few studies about urine culture of cats with LUTI. It is the first study on in vitro activity of cefovecin against bacterial isolates from cats with lower urinary infections in Istanbul, Turkey.

Measurement of M-mode echocardiographic parameters in healthy adult Van cats.

Cardiomyopathies are the most common type of cardiac diseases in cats. Although some normal echocardiographic values for cats have been published, there are variations based on breeds and gender. The objective of this study is to determine normal reference values for M-mode echocardiographic parameters in nonsedated healthy adult Van cats and to compare those values with data reported for nonsedated healthy cats of other breeds. A total of 40 clinically healthy Van cats of both sexes belonging to the Van Cat Research and Application Center of Yuzuncu Yil University were used. Body weight (BW) and 16 M-mode echocardiographic variables were measured in 40 healthy Van cats. The effect of gender and age on each echocardiographic parameter was analyzed and the relationship between BW and each parameter investigated. There was a significant relationship between gender and left atrial dimension during ventricular systole (LAD) and aortic root dimension at end-diastole (AOD) as well as between BW and interventricular septal thickness at end-diastole (IVSd) and end-systole (IVSs), left ventricular internal dimension at end-diastole (LVIDd), left ventricular posterior wall thickness at end-diastole (LVPWd), LAD, AOD, the left ventricular end diastolic volume (EDV) and the stroke volume (SV). A relationship between age and the SV parameter alone was also established. This present study is the first work on cardiac reference values for Van cats highlighting the differences in some M-mode echocardiographic parameters of healthy adult Van cats and other cat breeds, which should be considered when interpreting echocardiographic findings, in order to draw the correct conclusions regarding cardiac health.

Current scenario of viral diseases and vaccination strategies of cattle in Turkey.

The dairy and meat industry has rapidly developed in the last decade in Turkey and is playing a key role in supplying animal proteins for human consumption. Viral pathogens continue to threaten the dairy and meat industry leading to serious economic losses worldwide, including Turkey. The Turkish cattle industry has been vulnerable to the spread of viral diseases within the country in the continent. Combating animal diseases is crucial for the economy of Turkey. A good cattle health management policy may reduce the direct losses associated with viral diseases and thereby lead to increase in export of animals and animal products. Countries that are unable to combat animal diseases remain excluded from international trade. Control and eradication of cattle diseases require the availability of effective and practical interventions including vaccination and biosecurity measures. This review summarises the currently available information about viral diseases in cattle in Turkey and emphasizes the need for disease monitoring and research, along with implementation of disease control measures to mitigate economic losses to farmers and the country. The information presented here can be of great value in the research, prevention, and control of cattle diseases.

Presence of Antibodies to SARS-CoV-2 in Domestic Cats in Istanbul, Turkey, Before and After COVID-19 Pandemic.

Recent studies demonstrated that domestic cats can be naturally and experimentally infected with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). This study was performed to investigate the presence of SARS-CoV-2-specific antibodies within the domestic cat population in Istanbul, Turkey, before the coronavirus disease 2019 (COVID-19) and during the COVID-19 pandemic. Overall, from 155 cat sera analyzed, 26.45% (41/155) tested positive in the spike protein-ELISA (S-ELISA), 28.38% (44/155) in the receptor-binding domain-ELISA (RBD-ELISA), and 21.9% (34/155) in both, the S- and RBD-ELISAs. Twenty-seven of those were also positive for the presence of antibodies to feline coronavirus (FCoV). Among the 34 SARS-CoV-2-positive sera, three of those were positive on serum neutralization assay. Six of the 30 cats before COVID-19 and 28 of the 125 cats during COVID-19 were found to be seropositive. About 20% of ELISA-positive cats exhibited mainly respiratory, gastrointestinal, and renal signs and skin lesions. Hematocrit, hemoglobin, white blood cells, lymphocyte, and platelet numbers were low in about 30% of ELISA-positive cats. The number of neutrophils and monocytes were above normal values in about 20% of ELISA-positive cats. The liver enzyme alanine aminotransferase levels were high in 23.5% ELISA-positive cats. In conclusion, this is the first report describing antibodies specific to SARS-CoV-2 antigens (S and RBD) in cats in Istanbul, Turkey, indicating the risk for domestic cats to contract SARS-CoV-2 from owners and/or household members with COVID-19. This study and others show that COVID-19-positive pet owners should limit their contact with companion animals and that pets with respiratory signs should be monitored for SARS-CoV-2 infections.

M-mode echocardiographic parameters and indices in the normal German shepherd dog.

M-mode echocardiographic measurements were made from 50 healthy German Shepherd dogs (30 males and 20 females). The dogs were awake and unsedated, in right lateral recumbent position. The following parameters were measured on the echocardiographic images: interventricular septal thickness at end-diastole (IVSd), interventricular septal thickness at end-systole (IVSs), left ventricular internal dimension at end-diastole (LVIDd), left ventricular internal dimension at end-systole (LVIDs), left ventricular posterior wall thickness at end-diastole (LVPWd), left ventricular posterior wall thickness at end-systole (LVPWs), left atrial dimension (LAD), aortic root dimension (AOD), left atrial to aortic root ratio (LAD/AOD), right ventricular internal dimension at end-diastole (RVID), amplitude of mitral valve excursion (DE amplitude), velocity of mitral valve opening (D-E slope), and velocity of mitral valve closure (E-F slope). Fractional shortening (FS) was also calculated. The effect of gender and age on each echocardiographic parameter was analyzed and the relationship between body weight (BW) and each parameter was also investigated. There was a significant relationship between gender and LVPW in systole and diastole and FS. Significant association was also found between BW and IVS, LVID, and LVPW in systole and diastole, FS, LAD, AOD, RVID, DE amplitude, and D-E slope of the mitral valve.
