Opis:
The association between physiologically dependent pharmacokinetic parameters (CLB, T1/2β, Vdss) of marbofloxacin and body weight was studied in eight animal species based on allometric equation Y = aWb, where ‘Y’ is the pharmacokinetic parameter, ‘W’ is body weight, ‘a’ is allometric coefficient (intercept) and ‘b’ is the exponent that describes relation between pharmacokinetic parameter and body weight. The body clearance of marbofloxacin has shown significant (P<0.0001) relation with size (Bwt) in various animal species. However, half-life and volume of distribution were not in association with body weight. Although half-life and volume of distribution were not in a good correlation with body weight, statistically significant association between the body clearance and body weight suggests validity of allometric scaling for predicting pharmacokinetic parameters of marbofloxacin in animal species that have not been studied yet. However further study considering large sample size and other parameters influencing pharmacokinetics of marbofloxacin is recommended.

Opis:
Lymphocytic infiltrations located in the extracellular matrix often accompany canine skin cancer. They can be characterised as an inflammatory infiltration and/or a second tumour – lymphoma. The aim of this study was an immunohistochemical analysis of a lymphocytic infiltration which accompanies spontaneous skin cancer. Twenty basal cell carcinoma, 20 non-keratinizing squamous cell carcinoma, 20 keratinizing squamous cell carcinoma and 8 sebaceous gland carcinoma samples which were accompanied by a lymphocytic infiltration and/or secondary lymphatic follicles were verified histopathologically. The expression of bcl-2, CD3, CD79α, Ki-67, MCM-3 and MCM-7 in the lymphocytic infiltration was evaluated. Four types of lymphocytic infiltrations were found: I – diffuse bcl-2⁺, II – diffuse bcl-2⁻, III – follicular bcl-2⁺/⁻ where the centre was bcl-2⁻, and the marginal zone of the follicles and the extrafollicular area were bcl-2⁺ and IV – aggregated bcl-2⁺, where the centre and periphery were bcl-2⁺. The I and IV type corresponds to lymphoma, II type is non-neoplastic immune response and III type suggest reactive follicular hyperplasia. The proliferation of lymphocytes which demonstrated the expression of neoplastic markers (I and IV), suggests preneoplastic phase (pseudolymphoma) or lymphoma – the second independent tumour. A high proliferative index of the follicular blc-2⁺/⁻ follicular infiltration indicates an increased immunological response of the host against skin cancer.

Opis:
The contractile effects of PGF₂α (3 × 10⁻⁶ to 10⁻⁴ M) and PGE₂ (10⁻⁷ to 10⁻⁵ M) were examined on isolated branches of ovarian artery (OA) and extramyometrial branches of uterine artery (UA) collected from pigs in the luteal (day 10-12) and follicular phase (day 17-20) of the estrous cycle, and during early pregnancy (day 10-12). Strong contraction was demonstrated in both arteries during all investigated periods in response to PGF2α, which was significantly higher (P < 0.01) than to PGE₂, being negligible in the follicular phase. In UA, the effective dose of PGF₂α (ED50) amounted 7.9 × 10⁻⁶ M and 6.3 × 10⁻⁶ M in the luteal and follicular phase, and 5.0 × 10⁻⁶ M in early pregnancy. ED50 for PGE₂ reached 5.0 × 10⁻⁷ M in the luteal phase, and 4.1 × 10⁻⁷ M in early pregnancy. For both prostaglandins, the contraction was much stronger (P < 0.01) in OA than in UA branches. In OA, the ED50 for PGF₂α was 1.2 × 10⁻⁵ M in the luteal phase and was significantly higher (P < 0.05) than in the follicular phase (3.1 × 10⁻⁶ M) and early pregnancy (2.7 × 10⁻⁶ M). ED50 for PGE2 amounted 7.3 × 10⁻⁷ M in the luteal phase and 1.7 × 10⁻⁷ M in early pregnancy. Studies showed the influence of the estrous cycle and early pregnancy on OA branches sensitivity to the contractile effect of PGF₂α and the lack of this effect on UA branches, and the influence of the estrous cycle on UA and OA branch contraction in response to PGE2.

Opis:
In cattle, the prevention of diseases might be possible using dietary methods, with nutritional optimization of feed rations. For years significant influence has been associated with the addition of biotin, methionine and zinc (each given individually, or as chelate – Zn-methionine). The aim of this study was to evaluate the influence of biotin or biotin + Zn-methionine additives on the health and performance of cows, in the first and second trimester of lactation. This study was carried out in 3 groups of cows, 30 animals in each group. In the first group cows were fed the usual fodder used on the farm. In the second group biotin at 10 mg/day/cow was added. In the third group both biotin at 10 mg/day/cow and Zn-methionine at 5 g/day/cow were added. The administration of biotin increased the milk yield and reduced the occurrence of retained placenta, as well as endometritis puerperalis. However, the high doses of biotin suppressed ovulation and oestrus symptoms in the investigated cows (low progesterone levels on days 15, 21 and 45 after calving). Zn-methionine in comparison to biotin had a lower effect on the milk yield in the cows. Moreover, its supplementation improved the milk content, as well as some of the blood parameters; it also decreased the number of somatic cells in milk. The concurrent administration of biotin and zinc-methionine seemed to be a good method for the prophylaxis of subacute mastitis and for the improvement of the high yielding dairy cows’ productivity.

Opis:
The aim of the presented study was the estimation of optimal Ca and P levels applied before calving together with anionic salt addition, as an element of hypocalcaemia and hypophosphataemia prevention. The experiment was carried out during the dry period on 48 cows with similar milk yield in the previous lactation. Cows were divided into four groups. In group I (control) the amount of minerals was in accordance to NRC standards. In experimental groups (groups II-IV), two weeks before calving, cows received 140 g/day/head of hydrated magnesium sulphate to achieve dietary cation-anion difference at the level of about 50 mEq/kg DM. In groups II and III cows received calcium carbonate (100 g/day) 10 days a.p. (antepartum) (group II), or 5 days a.p. (group III), while cows in IV group received dicalcium phosphate (100 g/day) for 5 days a.p. Application of MgSO₄ × 7H₂O significantly affected the urine pH of cows from group III and IV 4-5 d. before calving – 6.45 and 6.81, respectively. The acidification of urine was observed after calving in group IV (7.13). In cows from group II (100 CaCO₃ 10 days a.p.) urine pH decline was not found (7.97-7.75). In that group the incidences of hypophosphatemia were noted (blood serum inorganic P level 1.41-1.46 mmol/l). Addition of magnesium sulphate prevented hypocalcaemia occurrence – 4-5 d. before calving the concentration of ionized Ca in blood serum was 1.11, 1.13 and 1.16 mmol/l (respectively for group II, III and IV). Reproductive functions were significantly improved after the application of CaCO₃ and CaHPO₄ for 5 days a.p. in comparison with control and group II – progesterone concentration in the blood serum on the 45th day of lactation was 1.396 – 1.409 vs 0.799 – 0.401. The correlation between progesterone and inorganic P level in serum was almost significant. Based on the obtained results a treatment optimal in prevention of hypocalcaemia and hypophosphataemia is the application of 50 g CaCO₃ and 50 g of CaHPO₄ for the last 5 days of the dry period together with MgSO₄ × 7H₂O given for 14 days a.p.

The aim of the present study was to investigate the occurrence of Anaplasma spp. in group of 50 fallow deer (Dama dama) from free-range farm in eastern Poland and determine what species of Anaplasma could infect these animals based on PCR gene sequencing. The PCR technique revealed the presence of 16S RNA Anaplasma spp. genetic material in the blood of 7 out of 50 examined animals. The sequences of the PCR products obtained showed a 100% homology with each other and 100% homology with GU 183908 sequence of A. phagocytophilum, isolated in our earlier study from a horse with clinical form of anaplasmosis. Here, we report the first molecular evidence of Anaplasma spp. among naturally infected fallow deer in eastern Poland.

Salmonella contamination in poultry feed is one of the main issues in poultry industry and public health. The aim of the present study was molecular detection and typing of Salmonella serotypes isolated from poultry feeds. Moreover, we determined the antibiotic resistance pattern and the ability of biofilm formation in the serotypes. To this end, eighty feed samples were collected from aviculture depots. Salmonella serotypes were identified by culture and PCR methods. For serological identification, a slide agglutination test was used. BOXAIR and rep-PCR methods were applied to evaluate the diversity of serotypes. The disc diffusion method was performed to evaluate the antibiotic susceptibility of serotypes to sixteen antibiotics. Biofilm formation was also assessed by the microtiter-plate test. From a total of 80 feed samples, 30 samples were contaminated with Salmonella spp., which were divided into 5 different serotypes belonging to B, C, and D serogroups. BOXAIR-PCR (D value [DI] 0.985) and rep-PCR (DI 0.991) fingerprinting of isolates revealed 23 and 19 reproducible fingerprint patterns, respectively. A higher antibiotic resistance was observed to ampicillin and doxycycline (100% each), followed by chloramphenicol (83.33%) and tetracycline (73.33%). Multidrug resistance (MDR) was detected in all Salmonella serotypes. Half of the serotypes possessed the ability of biofilm formation with varied adhesion strengths. These results revealed the high and unexpected prevalence of Salmonella serotypes in poultry feed with MDR and biofilm formation ability. BOXAIR and rep-PCR revealed a high diversity of Salmonella serotypes in feeds and subsequently indicated variation in the source of Salmonella spp. The unknown sources harboring high diversity of Salmonella serotypes indicated poor control, which could cause problems for feed manufacturing.

The literature analysed by REQUEST (REassesing QUinolone European STandard) using inclusion and exclusion criteria allows to make the conclusion that the proper use of fluoroquinolones (FQ) in canine colitis requires rigorously performed qualification to specific antimicrobial treatment. An infectious agent responsive to FQ therapy plays an integral role in the clinical manifestation of canine colitis, especially histiocytic ulcerative colitis (HUC) in young Boxer dogs. This supports the use of FQ in these cases. The Request guidelines for proper use of FQ in canine colitis is established, according to the available literature data.

Opis:
Recent years have seen in both human and veterinary medicine the development of numerous techniques allowing for evaluation and classification of changes in individual organs and tissues. Despite introduction of such techniques into diagnostics as among others, CT, MRI, CEUS or elastography, biopsy is still considered a “golden standard” and it is a procedure performed in order to obtain a final diagnosis. There are many biopsy techniques, such as fine needle aspiration biopsy, core biopsy as well as methods of performing a procedure, e.g. blind biopsy, biopsy under USG control and biopsy during laparotomy. In the article usefulness of biopsy techniques in relation to diagnostics of individual abdominal organ, as well as the procedure technique, contraindication and complications are discussed.

Opis:
The aim of the study was to evaluate the usefulness of elastography in the differential diagnosis of benign and malignant tumours of the mammary gland in dogs. The study was performed to 12 female dogs of different breeds aged 5-12 years in which tumoral lesions of the mammary gland were found in the clinical examination. In all the animals elastographic examination of the lesions was carried out and then the fine-needle aspiration biopsy was performed to determine the nature and degree of malignancy of the lesions. The examinations proved that benign neoplasms of the mammary gland showed low stiffness (average 22.42 kPa, range 19 to 42.4 kPa), whereas malignant neoplasms were characterized by high stiffness (average 235.44 kPa, range 171 to 300 kPa). On the basis of the results obtained we conclude that the elastography of proliferative lesions of the mammary gland is a useful diagnostic method for distinguishing benign neoplastic lesions from malignant neoplasms.

Opis:
Bordetella bronchiseptica is a widespread Gram-negative pathogen occurring in different mammal species. It is known to play a role in the etiology of infectious atrophic rhinitis of swine, canine kennel cough, respiratory syndromes of cats, rabbits and guinea pigs, and sporadic human cases have also been reported. The aim of this article is to present the occurrence of infections caused by these bacteria in domestic cats with respiratory symptoms, as well as to conduct a molecular analysis of the flaA gene B. bronchiseptica for the purpose of ascertaining whether cats become infected with one or more bacteria strains. B. bronchiseptica was isolated from the respiratory system of 16 out of 35 domestic cats with symptoms of respiratory tract infections. Polymorphism analysis of polymerase chain reaction products of B. bronchiseptica flaA was performed to reveal the possible differences in nucleotide sequences of the flagellin gene. The phylogenetic analysis of nucleotide sequences obtained during PCR indicated that the isolates of bacteria from our own studies are characterised by 100% homology of the analysed fragment of the flaA gene, which suggests maintenance of a single genotype of these microorganisms in the cat population. Moreover, the bacteria revealed full homology with reference strain B. bronchiseptica ATCC 4617, and 99.4% homology with strain B. parapertussis ATCC 15311. This indicates that the PCR optimised for the Bordetella spp. flaA gene, combined with sequencing of amplicons obtained in PCR, is an effective diagnostic method allowing differentiation of Bordetella spp. type microorganisms.
