Two new feather mites of the genus Proctophyllodes (Acari: Proctophyllodidae) from passerines of China (Aves: Passeriformes)

Two new species of the feather mite genus Proctophyllodes (Analgoidea: Proctophyllodidae) are described from two passerine birds (Passeriformes) in China: Proctophyllodes scleroticus sp. nov. from the Brandt's Mountain Finch Leucosticte brandti pallidior (Fringillidae) and P. micrurus sp. nov. from the White-rumped Snow Finch Onychostruthus taczanowskii (Passeridae). Proctophyllodes scleroticus sp. nov. belongs to the tricetratus species-group, and differs from the most similar species P. petroniae Atyeo & Braasch, 1966 by the following characters: in male, the genital sheath is heavily sclerotized, peach shaped, and extending to the level of setae g, anal suckers are surrounded with a pair of membranes, and terminal lamella is relatively greater, and in female, lobar shield is divided into two independent shields by the anal opening and anal opening extends beyond the level of setae ps1, terminal appendage is long. Proctophyllodes micrurus sp. nov. belongs to the musicus species-group, and differs from the most similar species P. saltatoris Atyeo & Braasch, 1966 by the following characters: in male, genital arch and the anterior part of opisthogastric shield are about the same width, anal suckers are surrounded with a pair of membranes, genital organ extends to the anterior 1/3 of the level of setae g and setae ps3, terminal lamella are located closely to each other and slightly greater, and in female, lobar shields are medially divided into two halves, terminal appendages are small, about 1/10 of setae h3, edge of the cleft is almost horizontal.

PREGNANCY AND ANORECTAL MALFORMATIONS

A wide range of pathology from ectopia of the anal opening to combined anomalies of the rectum and genitourinary tract refers to malformations of the anorectal region. Since the results of their treatment, both long-term and short-term, are not always satisfactory, the course of pregnancy can worsen the condition of the pregnant woman and affect the intrauterine fetus. This circumstance provides for the management of childbirth in a specialized institution.

Pre-Operative MRI in evaluation of Perianal fistulas

Background: Perianal fistula is a common and often an extremely distressing disorder. MRI is a preferred modality for the preoperative assessment of perianal fistulas. Aims and Objective: To evaluate the accuracy and predictive values of pre-operative MRI in diagnosing severity of perianal fistulas and the conditions associated with it like internal anal opening, secondary tract, abscess and supralevator extension. Materials and Methods: In this study, 44 patients with clinically suspected perianal fistulas underwent MRI for the evaluation of severity and presence of the associated conditions. St James’s University Hospital Classification was used to grade the perianal fistula. Pre-operative MRI grading was compared with the surgical findings in the 26 operated patients. Results: Out of 44 clinically suspected perianal fistulas, 41 (93%) were diagnosed as perianal fistulas by MRI. The most common type was grade 1 seen in 12(27.3%) patients followed by grade 4 fistula seen in 10(22.7%) patients. All 26 patients evaluated by surgical findings for severity of perianal fistulas were found to be graded in identical grades by pre-operative MRI. MRI was 100% sensitive in picking up all five grades. Conclusion: MRI helps in the accurate delineation of fistulous tract, identification of secondary tract and abscess.

Surgical Management of Atresia Ani in a Crossbred Calf

Atresia ani is a congenital defect that describes the absence of a normal anal opening. It is fatal unless a surgical correction is carried out to provide an anal opening. In female, the rectum may break through the vagina, forming a rectovaginal fistula permitting defecation via the vulva. Surgical treatment of atresia ani is indicated to save the animal’s life and to improve body weight gain. Intestinal atresia has been reported as a congenital defect in all species of domestic animals (Gass and Tibboel, 1980). Atresia ani may be caused by genetic disorders (chromosomes or transgenesis), environmental factors, or a combination of both (Cassini et al., 2005). Monsang et al. (2011) reported a case of double vulva with atresia ani in a crossbred calf. Atresia ani should be treated by a surgical operation to solve the problem, improve body weight gain, and reduce economic loss. The present report records a case of atresia ani in a crossbred cow-calf and its successful surgical correction.

Sanitary evaluation of fishes fished from the ponds of the Sumy region

Introduction. Fisheries are a traditional industry in Ukraine, started more than 300 years ago. There are more than 1 million hectares of fisheries in the country, including about 200,000 hectares of ponds. The main breeding sites are various carp breeds, white and mottled silver carp, white cupid. Fish and fishery products are important in human nutrition and make up a large part of their diet. In many countries of the world, fish is the main focus of the food industry. The goal of the work. The purpose of our research was to carry out a sanitary evaluation of fish caught from the sums of Sumy region. Materials and methods of research. These studies were conducted under the conditions of the Department of Veterinary Expertise, Microbiology, Zohygiene and Safety and Quality of Livestock Products of Sumy National Agrarian University and in the fisheries of Sumy region. Selection and preparation of fish samples for research were carried out according to GOST 7631-85. For the study used fish from the carp family, which are most common in the fishery farms of Sumy region. Results of research and discussion. When conducting organoleptic studies in sample No. 1, the following indicators were found: mouth closed; eyes clear, pale, convex with transparent cornea; cheeks and jaws pale; gill caps tightly against gills; gills with viscous, clear and transparent mucus, bright red, with a slight odor of fresh fish moisture, mucus in a small amount, viscous and transparent, odorless or with a slight odor of dampness; scaly shiny, clean; fins of lifelong appearance and color, without damage, the back is dense, elastic, the fossa from the pressure of the finger quickly, almost immediately disappears; the anal opening is closed, which corresponds to the indicators of good-quality fish; and in sample No. 2, the mouth is open; eyes sunken, dull, pale pink or pale red, with dull cornea; cheeks and jaws pale pink; gill caps do not fit snugly, move away from gills; on the gills dull mucus, mucus much; scales dim; fins covered with thick turbid mucus, at the base of the fins mucus pink or reddish; the back is soft, the fossa from the pressure of the finger slowly disappears; the anal opening is slightly swollen, pink-red, which indicates the quality of fish of dubious freshness. Meat toxicity determination of all fish species studied was performed using Tetrachymena pyriformis infusions. The absence of inhibitory effect on the survival of the infusions, their growth and behavioral response, the degree of mobility, morphological parameters. This testified to the absence of toxicity of all tested fish meat samples. After 3 hours the infusions were alive and mobile. Also, by determining the level of histamine, we found that it was within normal limits. Thus, the histamine content in sample No. 1 was 20,5 ± 3,1 and in sample No. 2, respectively, 22,4 ± 5,5 mg/kg. Conclusions and prospects for further research: 1. In the study of fish samples caught from the sums of Sumy region it was found that by organoleptic and physicochemical indicators, sample No. 1 corresponded to good-quality fresh fish, and by carrying out the study of sample No. 2, the results obtained were characteristic of fish of dubious freshness. The presence of live helminth larvae in humans and animals was not detected in all of the samples of chilled fish we selected for veterinary examination. Microscopy of specimens from specimens No. 1 revealed no microflora; drugs were stained poorly, which is characteristic of fresh fish, and in the preparation of sample No. 2 from the surface layers in one of the fields of view revealed 30-35 diplococci. In the future it is planned to carry out monitoring of the veterinary and sanitary evaluation of fish caught from the Sumy basin.

Case Report: Newborn with Anorectal Malformation

Anorectal malformations are defined by the relationship of the rectum to the sphincter complex and can be classified as high and low anomaly based on whether meconium is present or absent, presence of dimple, anocutaneous reflex, sacral abnormality or presence of meconium in urine. The diagnosis should be made in the delivery room by inspecting the perineum. Meconuria with absence of anal opening invariably indicates a high malformation which requires a colostomy in the newborn period. Low malformations do not become evident until 24 hours when the meconium may show up in the perineal fistula. These defects can be managed by a perineal anoplasty without a colostomy in the newborn period. A prone cross table lateral shoot abdominal film is required if clinical information at 24 hours is insufficient to decide whether a colostomy is needed. We present a case of newborn, day 4 of life, who did not pass meconium since birth, had abdominal distension, vomiting, poor feeding and lethargy since last 2 days. Anal area showed pigmentation with presence of median raphe, anal dimple and slightly formed anal opening. Baby was initially thought as a case of low type imperforate anus. On further evaluation, was found to have meconuria too. Invertogram done showed high type defect. Rest of the examination was normal. Supportive therapy was initiated and baby underwent transverse loop colostomy for high type imperforate anus on day 5 of life. So it is always advisable to confirm the type of anorectal malformation both clinically and by doing required investigation before deciding for any operative intervention like colostomy or anoplasty, as clinical examination and investigation may not correlate in all occasions. Evaluation should also include screening out for associations and other sacral anomalies. BJHS 2018;3(2)6: 500-503.

Morphological ontogeny of Heptacarus hirsutus (Acari, Oribatida, Lohmanniidae), with comments on Heptacarus Piffl

The morphological ontogeny of Heptacarus hirsutus Wallwork, 1964 is described and illustrated. All instars of this species have two pairs of exobothridial setae, which is characteristic for the lower Oribatida. They have strong chelicerae, anal opening in a posteroventral position, and thick legs I and II, features which are typical for xylophagous mites. The larva has 34 gastronotal setae, including inguinal h4, a striking feature of the lower Oribatida, this stage has also a long, cudgel-shaped Claparède’s organ. In the next instars of H. hirsutus, a strong hypertrichy occurs on the posterior part of the hysterosoma, and the number of setae increases in the protonymph, deutonymph, tritonymph and adult to about 60, 75, 95 and 115 setae, respectively. In the deutonymph, tritonymph and adult of H. hirsutus, the ano-adanal plate is incompletely fussed.

Morphological ontogeny of Protoribates dentatus (Acari, Oribatida, Haplozetidae)

The morphological ontogeny of Protoribates dentatus (Berlese, 1883) is described and illustrated. The juveniles of P. dentatus are elongated, oval in cross section, and their prodorsal, gastronotal setae and most setae on the legs are thin, smooth or with short barbs, which is typical of xylophages. Typical for this group is also a posterior position of the anal opening and relatively thick leg segments and claws, especially on leg I. The larva of P. dentatus has 11 pairs of gastronotal setae, including h2;and setae c2, la and lm are with excentrosclerites. The nymphs have 15 pairs of setae, of which c2, l- and h-series are with excentrosclerites. The adult of this species has a long seta ad1 (which is short in most congeners) and the number of claws varies on all leg tarsi.

Morphological ontogeny and ecology of Adoristes ovatus (Acari: Oribatida: Liacaridae), with comments on Adoristes Hull

The morphological ontogeny of Adoristes ovatus (C.L. Koch, 1839) is described and illustrated. The adult has the interlamellar seta shorter than the lamella and the translamella is usually absent, but can also be incomplete, or present as a thin line. The juveniles are unpigmented, oval in cross-section, with thin and smooth prodorsal and gastronotal setae, and with the anal opening in the posteroventral position, which is typical of xylophages. The legs and claws of juveniles are relatively thick, especially leg I, and the leg setae are smooth or with short barbs. All juveniles have a sclerotized semicircle located anterior to each prodorsal seta le. The larva has 11 pairs of gastronotal setae, the nymphs have 12 pairs, without the d-series. The mean body length of females is larger than males, but varies greatly among samples (445–735 μm) and the largest females can be 1.5 times longer than the smallest males. The sex ratio and the number of gravid females also vary among samples. We provisionally consider Adoristes (Gordeeviella) Shtanchaeva, Subías & Arillo, 2010 a junior synonym of Adoristes Hull, 1916.
