A survey to estimate the prevalence of verotoxigenic E. coli (VTEC) or enterohaemorrhagic E. coli (EHEC) in rectal swabs from healthy dairy cattle aged three weeks, three months and one year was conducted in three herds from the Czech Republic. Screening for the presence of the stx1, stx2 and eaeA genes in faecal swab cultures was performed by PCR, and in positive samples, isolated colonies were examined. Immunomagnetic separation was used for the isolation of the VTEC serogroup O157 from samples. VTEC were detected in animals from all three herds under study. In the group of 3-week-old calves, VTEC were only detected in samples collected...

Metabolomics focused on reproduction have been the subject of special interest in the past decade. Metabolite profiling provides detailed information on the status of follicular fluid and follicular cells which accompany the growing oocyte. Although nutrients present in the diet reach oocytes via the follicular fluid, it is not evident whether oocyte/embryo quality can be predicted based on the follicular fluid composition. Since this phenomenon has not yet been investigated in the pig, the aim of the present study was to investigate associations between diet composition and (1) selected markers related to developmental potential of oocytes (brilliant...
Migratory dynamics of cyathostomin larvae in a Bermuda grass pasture in South America

Studies of the migratory dynamics of cyathostomin infective larvae (L3) in different seasons and with two types of irrigation were carried out over 12 months (September 2006 to September 2007) in the subtropical climate of the Baixada Fluminense region of Rio de Janeiro state, Brazil. Four faecal masses weighing 500 g each from naturally infected horses were placed in a Bermuda grass (Cynodon dactylon) pasture in the beginning of each season. Samples of faeces and grass were collected every 15 days until the end of each season. The highest recovery in faeces occured in Autumn (491 910 L3/kg dried herbage) and in pasture...
Malicious animal intoxications: poisoned baits
M. Giorgi, G. Mengozzi
Vet Med - Czech, 2011, 56(4):173-179 | DOI: 10.17221/3148-VETMED
Data of toxicological analyses for baits carried out in the Laboratory of Toxicology of the Department of Veterinary Clinics (University of Pisa) over a 10-year period are summarized. The 508 lures have been grouped according to their preparation features. This classification has generated six classes: (1) baits prepared with discarded or out-of-date food; (2) laborious and original/particular baits; (3) baits containing more than one toxic substance; (4) baits containing non-toxic material; (5) baits prepared with non-food material and (6) in vivo baits. The most commonly detected toxic substances in baits were organophosphorus and carbamate...

Vet Med - Czech, 2011, 56(4):180-186 | DOI: 10.17221/3150-VETMED
This study was conducted to investigate the effect of heat stress (i.e., elevated ambient temperature - Ta; 36 °C ± 3 °C) on growth performance, mortality rate, and on some haematological and biochemical parameters in different categories of gender and age of New Zealand White (NZW) rabbits. Animals were divided into two main groups (control and treatment), in each group there were 56 rabbits: adult females (n = 20), adult males (n = 4), growing females (n = 16), and growing males (n = 16). Results revealed that total and daily feed intake, feed conversion ratio, and total and daily gain in body weight for...
Haemodynamic and renal effects of resuscitation of dogs from haemorrhagic shock with hypertonic saline or Lactated Ringer's solution combined with whole blood

Vet Med - Czech, 2011, 56(4):187-201 | DOI: 10.17221/3149-VETMED
Despite numerous studies on haemorrhagic shock treatment, the choice of fluid and the rate of administration is a subject of controversy. Early haemodynamic effects, neuroendocrine response and renal function following acute sodium load with either hypertonic saline (HS) or Lactated Ringer's (LRS) were investigated in a model of controlled haemorrhagic shock. Six anaesthetized dogs were bled 30% of calculated blood volume, i.e., 27 ml/kg b.w. over 15 min and left untreated for 30 min. Afterward, the dogs were treated with either HS 4 ml/kg b.w. or LRS 81 ml/kg b.w., followed by whole blood. After a resting period of at least 30 days, the dogs underwent...
Distribution of the arterial supply to the lower urinary tract in the domestic tom-cat (Felis catus)

This study was aimed at determining the arterial supply and gross vascular architecture of the urinary bladder in the male cat. For this purpose, the urinary bladders of 10 cats were evaluated. Organ vascularization was investigated using the latex injection technique. The feline urinary bladder was found to be supplied by the prostatic artery, which stemmed from the internal pudendal artery and the umbilical artery that originated from the internal iliac artery. The umbilical artery extended caudally to form the cranial vesical artery, which was later distributed into the corpus and apex of the urinary bladder. The feline prostatic artery divided...

Vet Med - Czech, 2011, 56(4):209-213 | DOI: 10.17221/3151-VETMED
Over a period of five years (2005-2010) a total of 358 red fox (Vulpes vulpes) serum samples were collected during regular hunting procedures, mostly in the continental part of Croatia. All samples were tested using the microscopic agglutination test (MAT) for the presence of specific antibodies (Ab) to 12 Leptospira spp. pathogenic serovars. Specific antibodies for 11 different Leptospira spp. serovars (Australis, Sejroe, Icterohaemorrhagiae, Saxkoebing, Grippotyphosa, Tarassovi, Ballum, Pomona, Poi, Batavie, and Canicola) were detected in 121 red fox serum samples (33.8%). Among the positive samples antibodies for serovar...
