Summary Reports of Pearsonema plica and Eucoleus böhmi infections in wolves (Canis lupus) in Europe are limited and data on associated lesions are lacking. In the present study urinary bladders, nasal turbinates and faecal samples from 8 necropsied wolves were examined for P. plica and E. böhmi infections and associated lesions. P. plica was identified in the bladder of four wolves. At histological examination, follicular chronic cystitis and eosinophilic cystitis were found. E. böhmi nematodes and eggs were identified from the nasal turbinates and rectal faecal samples of three wolves. Worms and eggs were found embedded in the mucosa among the nasal bone laminae. Two wolves were found coinfected by P. plica and E. böhmi. This is the first report of P. plica and E. böhmi infections in wolves from Italy and the first description of pathological lesions associated with P. plica infection in wolves.

AbstractThe present study was carried out to describe the reproductive system of a single adult female wolf, including the uterine horns, cervix, ovaries and follicles. The cumulus oocytes complexes (COCs) and oocytes were also examined. The results showed that the size of each ovary was about 9 × 6 mm with an average of weight of 461.3 mg. The uterus was Y-shaped, and the length of each uterine horn was 14 cm. The distance from the cervix to the bifurcation of the uterine horns was also 14 cm. The left ovary had two large follicles on the surface with a diameter more than 4 mm, while the right ovary had no protuberant follicles. The ovaries were covered with a lot of fat, and were well developed. The COCs derived from the antral follicles were dark, and the nuded oocytes had a dark cytoplasm. The diameter of the oocytes removed from the antral follicles was 116.8 μm on average. The ovaries had a smooth surface and all the follicles were under the surface except for two big follicles on the left ovary. Histological examination of the ovaries by haematoxylin and eosin staining demonstrated that the primordial, primary, preantral and antral follicles were scattered in the cortex, the medulla was abundant with blood vessels. This study preliminarily reveals the features of the wolf reproductive system and the structure of its oocytes and ovaries, which might be indicative for further study and the protection of the species.

ABSTRACT An 11 yr old spayed female domestic longhair cat was presented for an acute onset of vomiting. Abdominal radiographs and ultrasound revealed severe gastric dilatation (GD) without evidence of gastric outflow obstruction. On esophagogastroduodenoscopy, the duodenal mucosa was mildly erythematous, and a moderate, diffuse, chronic enteritis was found by histological examination of duodenal biopsies. Large numbers of Sarcina-like bacteria without associated inflammation were present in gastric mucosal biopsies. To the authors’ knowledge, this is the first report of GD associated with colonization by Sarcina-like bacteria in a cat. Gastric colonization by Sarcina-like bacteria should be suspected when cats are presented with acute onset of GD and vomiting.

This study constitutes the first report of the gametogenic cycle of the scleractinian coralsSolenastrea bournoniandStephanocoenia intersepta. Tissue samples were collected near Ft. Lauderdale, Florida, USA between July 2008 and November 2009 and processed for histological examination in an effort to determine reproductive mode and potential spawning times. BothS. bournoniandS. interseptaare gonochoric, broadcast spawning species. Gametogenesis ofS. bournonibegan in April or May whileS. interseptahad a much longer oogenic cycle that began in December with spermatogenesis beginning in July. Though spawning was not observedin situ, spawning was inferred from the decrease of late stage gametes in histological samples. In addition, histological observations of oocyte resorption and released spermatozoa were used to corroborate spawning times. Data indicate thatS. bournonispawns in September whileS. interseptaspawns after the full moon in late August or early September.

A subsample consisting of fifty fecal samples from wild Iberian Wolf (Canis lupus signatus), from the northwest of Spain were collected in the field. The samples were analyzed for cysts of Giardia sp. and oocysts of Cryptosporidium sp. using a direct immunofluorescence antibody test (IFA). Giardia sp. and Cryptosporidium sp. were found in 20.0 % of the samples examined. Simple infections were more frequent (90.0 %) with seven (14.0 %) positive for Giardia sp. and two (4.0 %) positive for Cryptosporidium sp. To the authors’ knowledge, this is the first report of occurrence of Cryptosporidium sp. in Iberian Wolf.

AbstractEighty-nine samples of grey wolf (Canis lupus L.) faeces were collected between 2002 and 2004 from two areas in the western Beskidy Mts (south Poland). Helminth eggs were observed in 56.2% of faeces examined. These included: Alaria alata (2.2%), taeniid eggs (11.2%), Toxocara canis (5.6%), Toxascaris leonina (1.1%), Eucoleus aerophilus (14.6%), Ancylostoma caninum (12.3%), Uncinaria stenocephala (37%) and unidentified roundworm eggs of the family Strongyloididae (1.1%). Eucoleus aerophilus is recorded for the first time from Poland. The results are compared with the helminth fauna of other wolf populations in Europe.

Summary Three acanthocephalan parasites, namely Neoechinorhynchus (Neoechinorhynchus) quinghaiensis, Rhadinorhynchus ganapatti, and Bolbosoma sp. are reported for the first time from Philippine fishes. N. (N.) quinghaiensis (Neoechinorhynchidae) may have been introduced into the country through the importation of carp species from China, where this parasite was first described and is presumed to be naturally occurring. The adult worms of R. ganapatti and the isolated cystacanth of Bolbosoma sp. represent the first record of parasites from both the family Rhadinorhynchidae and Polymorphidae in Philippine waters, respectively. These three new records encompass a third of all listed acanthocephalan parasites that have been reported in Philippine fish species to date, highlighting the need for more biodiversity-focused parasitology research, in light of potentially numerous more undocumented parasite species.

This paper represents the first report on the presence of a cardiorespiratory nematodes in the gray wolf from Bosnia and Herzegovina. The heart and lungs with corresponding trachea from wolves that were legally hunted from 2009 to 2019 have been analysed by routine post mortem macroscopical examination. A total of 25 heart samples were examined for the presence of Dirofilaria immitis and Angiostrongylus vasorum, while five lungs with trachea samples were examined for the presence of lung nematodes. There was no confirmed presence of Dirofilaria immitis and Angiostrongylus vasorum, while the presence of species Eucoleus aerophilus was established in one case (20%). This study confirms that the gray wolf is a source of infection with Eucoleus aerophilus to other natural hosts.
