2018
Debbou-Iouknane, Nedjima(University Abderrahmane Mira Bejaia Department of Environment Biological Sciences) | Benbarek, Hama(University Mustapha Stambouli Department of Agricultural Sciences) | Ayad, Abdelhanine(University Abderrahmane Mira Bejaia Department of Environment Biological Sciences)
The prevalence of coccidiosis was determined and Eimeria species were identified in farms at different locations in the Bejaia region, Algeria. The study was conducted from February to December 2016. Unvaccinated birds were selected randomly. Samples from litter and faeces were collected randomly (147 and 109, respectively). Necropsy and parasitological examinations were carried out using standard methods. Of the samples examined, 93 out of the 147 litter samples and 78 out of the 109 intestinal content samples were infected with Eimeria oocysts (63.26% and 71.55%, respectively). Mixed infections with Eimeria spp. were observed in some of the positive farms, with an overall prevalence of 54.28%. Five species of Eimeria (viz. E. acervulina, E. tenella, E. maxima, E. brunetti and E. mitis) were identified with different indices. Eimeria acervulina followed by E. tenella were the predominant species infecting chickens at the farms visited (32.05% and 26.92%, respectively). Statistically, the most prevalent Eimeria spp. was E. Acervulina (p < 0.05). This study demonstrated that coccidiosis is an omnipresent parasitic intestinal disease. It could strongly decrease production performance in broiler chickens.
Afficher plus [+] Moins [-]Prevalence of canine Babesia and Ehrlichia co-infection and the predictive value of haematology

Canine babesiosis and ehrlichiosis are important tick-borne infections in South Africa. Many South African general veterinary practitioners perceive co-infection with Ehrlichia spp. as a common occurrence in dogs with babesiosis. Studies about the prevalence of co-infection in South African dogs are lacking. This retrospective study aimed to determine the prevalence of Ehrlichia co-infection in dogs with babesiosis. Additionally, the predicative value of specific haematological variables for co-infection was evaluated. The study population consisted of 205 dogs diagnosed with canine babesiosis presented to the Onderstepoort Veterinary Academic Hospital (OVAH) in 2006 and between 2011 and 2013. The Babesia-infected dogs were grouped based on presence or absence of an Ehrlichia spp. co-infection. Ehrlichia spp. co-infection was confirmed using polymerase chain reaction. Positive and negative predictive values (PPVs and NPVs) of leukopenia or thrombocytopenia for co-infection were also calculated. The prevalence of Babesia spp. and Ehrlichia spp. co-infection in this cohort of dogs was 2%. In the babesiosis dogs, the PPV of leukopenia for co-infection with Ehrlichia spp. was 1.3%, and the NPV 97.4%. Similarly, the PPV and NPVs of thrombocytopenia for co-infection were 2.1% and 100%, respectively. Co-infection with Ehrlichia spp. was a rare occurrence in dogs with babesiosis presented to the OVAH. Normal leukocyte or platelet counts confidently ruled out the presence of concurrent ehrlichiosis in this cohort of dogs. However, the diagnosis of Ehrlichia co-infection based on the presence of thrombocytopenia or leukopenia would have been associated with false positive results in more than 97.4% of cases.

2018
Göpper, Byron M.(University of Pretoria Department of Anatomy and Physiology) | Voogt, Nina M.(University of Pretoria Department of Anatomy and Physiology) | Ganswindt, Andre(University of Pretoria Department of Anatomy and Physiology ,University of Pretoria Department of Zoology and Entomology Mammal Research Institute)
Ozobranchus spp. are leeches that feed solely on turtle blood. They are common ectoparasites found on a range of marine turtle species, with some species of the leech being implicated as vectors of fibropapilloma-associated turtle herpesvirus (FPTHV). Green (Chelonia mydas) and hawksbill (Eretmochelys imbricata) turtles are the two commonly occurring species in the inner granitic islands of the Seychelles. Routine monitoring of nesting turtles on Cousine Island, Seychelles, allowed for opportunistic sightings of leeches on two hawksbill females. In both cases infestation was low, with three leeches collected off one female turtle and five off the other. No obvious signs of papillomas secondary to infection of FPTHV were seen. All of the turtle leeches collected were determined to be Ozobranchus margoi as they had five pairs of lateral digiform branchiae. The specimens were deposited in the Seychelles Natural History Museum on Mahé. To the best of our knowledge this is the first record of Ozobranchus margoi recorded in the inner granitic Seychelles on hawksbill turtles.

Kohansal, Maryam(Fasa University of Medical Science Department of Medical Biotechnology ,Payame Noor University Department of Biology) | Asad, Ali Ghanbari(Fasa University of Medical Science Department of Medical Biotechnology)
Shiga toxin-producing Escherichia coli (STEC) O157 and non-O157 are food-borne pathogens and contaminants of foods of animal origin. This study was conducted to investigate the presence of virulence and integrase genes in STEC isolates from diarrhoeic calves in Fars Province, Iran. Five hundred and forty diarrheic neonatal calves were randomly selected for sampling. Rectal swabs were collected and cultured for isolation and identification of E. coli following standard methods. The isolates were analysed for the presence of class 1 integrons and bacterial virulence factors using polymerase chain reaction (PCR). Antimicrobial susceptibility testing was performed using the Kirby-Bauer disc diffusion method. Out of 540 diarrhoeic faecal samples, 312 (57.7%) harboured E. coli and 71 (22.7%) of them were identified as STEC: 41(69.5%) carried the stx2 gene, 21 (35.6%) carried the stx1 gene and 3 (5%) carried both. Twenty-six (44%) of the isolates showed the eae gene. Among the STEC isolates examined for susceptibility to eight antimicrobial agents, erythromycin and penicillin (96.8%) resistance were most commonly observed, followed by resistances to ampicillin (71.8%), tetracycline (62.5%) and trimethoprim/sulfamethoxazole (39%). Integrons were detected by PCR in 36% of the STEC tested isolates, 57 (89%) of which showed resistance to at least three antimicrobial agents. Our findings should raise awareness about antibiotic resistance in diarrhoeic calves in Fars Province, Iran. Class 1 integrons facilitate the emergence and dissemination of multidrug-resistance (MDR) among STEC strains recovered from food animals.

Bastan, Idil | Bas, Bulent
The aim of this study was to draw attention to the clinical course of the disease and some laboratory findings in cats diagnosed with Toxoplasmosis. Toxoplasma gondii seropositive 14 cats were used in this study. A serological evaluation was carried out to determine the presence of Toxoplasma gondii specific IgG using commercial diagnostic kits, by the enzyme-linked immunosorbent assay method. Hematological and clinical changes of those cats were recorded.Of 14 cats, neural symptoms such as behavioral changes, seizures, ataxia and nystagmus were detected in 11 cats, uveitis in 5 cats and diarrhea in 4 cats. Serum urea, creatinine and bilirubin levels were normal in all cats. However, Anemia (decreased Hb, RBC, PCV) in 8 cats (57.1%), monocytosis in 6 cats (42.8%), neutrophilia in 5 cats (35.7%), hypoalbuminemia in 5 cats (35.7%) and increased AST and ALT levels in 3 cats (21.4%) were detected.It was concluded that clinical Toxoplasmosis in cats is characterized by neurological, ocular and gastrointestinal sings and hematological sings such as anemia, monocytosis, neutrophilia and hypoalbuminemia that clinically patient cats should also be evaluated in terms of Toxoplasmosis in cats.

In this study, prevalence of clinical diseases and disorders of goat at upazilla veterinary hospital, Pirojpur, Bangladesh were calculated and analyzed based on age, sex and seasonal variation during the period from June, 2014 to May, 2015. The protocol of disease diagnosis was mainly based on clinical sings, physical examination and some common laboratory techniques. Total 277 clinical cases (diseases and disorders) of goat were recorded for this study.The prevalence of medicinal, surgical and gynecological cases were 47.29%, 41.16% and 11.55%; respectively. In medicinal cases, prevalence of diarrhea was highest (22.90%) compare to bloat (13.74%), pestedes-petites ruminant (13.74%), shipping fever (12.98%), fever (11.45%), conjunctivitis (11.45%), mite infestation (10.69%) and tetanus (3.05%). Female (63.36%) and older goat (54.20%) were more susceptible to different types of medicinal cases. In surgical cases, prevalence of castration was highest (52.63%) compare to abscess (17.54%), dog bite (16.67%) and foot rot (13.16%). Summer season represented highest surgical case (49.12%) prevalence followed by winter season (33.33%) and rainy season (17.54%). In gynecological cases, prevalence of retained placenta was highest (37.50%) compare to vaginal prolapsed (31.25%) and dystocia (31.25%). Seasonal variation was also observed in gynecological cases and summer season (50%) represented highest case prevalence followed by winter season (37.5%) and rainy season (12.50%).Those prevalence of different diseases and disorders of goat will helpful for clinician to know the disease occurrence according to goat’s age, sex and seasonal variation in this area and will help them to take proper preventive measures against those diseases and disorders.

Elmacioglu, Sibel | Yaman, Mehmet | Zerek, Aykut | Akkucuk, Serife | Karagoz, Mustafa | Erdem, Ipek
Besides the yield loss of the pigeons those are infested with ectoparasites they are also susceptible against the other infections because of weakened immunity. Thus it has been evaluated the situation of ectoparasites of domestic pigeons and determined the prevalance in Antakya region. Materials and Totally 100 domestic pigeons (Columba livia domestica) which are fed for hobby in Antakya region were examined with respect of ectoparasites. The prevalance of ectoparasites of domestic pigeons has been determined and identified according to the literature.The prevalance of ectoparasites of domestic pigeons was determined as 52% and three different ectoparasites were detected. Columbicola columbae was the dominant species with a percentage of 45%, Argas reflexus and Pseudolynchia canariensis were also dedected with a percentage of 5% and 2%, respectively. Despite the higher percentage of infestation in female pigeons (54,5%) when compared with males (48,9%) and adults (56,9%) when compared with juveniles (42,9%) no significant difference was found statistically (p>0.05). But louse infestation of adult pigeons (58,3%) was significantly higher than the juvenile pigeons (28,5%) statistically (p<0.05).The yield and perfomance loss in domestic pigeons should not be ruled out. Therefore hygien of shelters and ventilation is crucially important. Ectoparasiter situation should be monitorized and gotten under controlled.

A two-year old lioness (Panthero leo) was referred to our clinic with nasal and oral bleeding, vomiting and anemia. As being informed by the owner; we learned that the lion had a history of anorexia, nasal discharge, fatigue, dehydration and apathy just one month prior to admitting the clinic. At the laboratory examination Urea, Creatinine and RBC (red blood cell) were higher than normal. Coronavirus, Feline Leukemia Virus, Feline Immunodeficiency Virus (Rapid FIV/Ab FeLV Ag Test Kit, Bionote®) agents were checked with commercial immunochromatographic rapid test kit and found as negative. Heamobartonella sp was found by blood smear. Enrofloxacin (Baytril-K % 5, Bayer®) 10 mg/kg dose for 10 days once a day and vitamin K and supportive fluid were given for treatment. All clinical signs and abnormal blood values returned to normal levels after 17 days. This report indicated that Heamobartonella sp is important agent also for wild cats and all cats should be controlled for this to infection even if suffered from renal failure.
