Abstract
Nasopharyngeal myiasis caused by the camel nasal bot, Cephalopina titillator, is very common in old world camelids and is usually found at necropsy or during meat inspection. Herein we report massive infection with C. titillator in a 9 years old female one-humped camel slaughtered on February 18, 2024 in the village of Kizil Uy, Nukus District, Republic of Karakalpakstan, northwestern Uzbekistan. A total of 69 larvae: 20 first stage larva (28.9%), 31 second stage larva (44.9%), and 18 third stage larva (26.0%) were detected in the nasal passages and pharynx of the camel. Morphological and morphometrical characters of all larval stages are illustrated and detailed in this article. To our knowledge this is the first record of camel nasal bot infestation in Uzbekistan. Future epidemiological studies are needed to shed light on the prevalence, seasonal fluctuation, clinical impact and economic burden of nasopharyngeal myiasis in dromedary camels of the country.

Abstract
The conventional treatment for tegumentary leishmaniasis is meglumine antimoniate, which needs parenteral administration, has increased therapeutic failure, and produces serious adverse effects, justifying the search for therapeutic alternatives. We report here the preliminary results of a phase II clinical trial in patients with mucosal leishmaniasis, in which the efficacy of oral miltefosine versus the antimonial compound was assessed. The evaluation of response to the treatment was performed by monitoring with nasopharyngeal video-fibroscopy, using a score of mucosal injury severity for patients at each follow-up point. We found no significant differences so far between the number of patients cured with miltefosine or conventional chemotherapy. The favorable results of this study suggest that miltefosine could be an effective and safe oral therapeutic alternative in the region.

Abstract
Camel botfly, Cephalopina titillator, causes severe economic losses to the camel industry in many camel-producing areas of the world. A total of 1328 camels, of different age groups and of both sexes, slaughtered at Mashhad Slaughterhouse, Khorasan Razavi Province, eastern Iran were inspected for infestation with larvae of C. titillator. After slaughtering, the head was dissected and grossly inspected for presence of C. titillator larvae and other gross abnormalities. Seven hundred and seventy one camels (58.1%) were infested with this larvae and the rate of infestation was significantly greater in the colder months (69.8%) compared to those of warmer ones (36.2%) and in males (65.0%) compared to those of the female camels (45.60%). The prevalence rate was lower in camels younger than 2 years old (39.8%) compared to those of 2-6 (61.5%) and over 6 years old (62.8%). Proper tissue sections from nasal cavity, pharynx, turbinates and frontal sinuses of 30 infested and 10 uninfested camels processed routinely for histopathological studies. The mucous membranes of the nasopharynx and frontal sinuses of the heavily infested camels were congested, swollen, edematous, occasionally haemorrhagic and infrequently occupied by copious amounts of muco-fibrinous exudates. Dark brown or black nodules were seen in the mucous membrane of these structures. The main histopathologic changes were desquamation, hydropic degeneration and hyperplasia of the mucosal epithelium with focal or diffused infiltration of lymphocytes, plasma cells, macrophages, eosinophils and fibroblasts in the mucosa and submucosal layers. Hyperemia of the blood vessels of the nasopharyngeal wall, goblet cell hyperplasia and cystic dilatation of submucosal secretory glands were also present in the heavily infested animals. This investigation was designed to record the prevalence together with gross and histopathological changes observed due to C. titillator in camels in eastern provinces of Iran.

Abstract
Hydatid disease is caused by the parasitic tapeworm Echinococcus. This parasite in larval stage can thrive in many parts of the body, most commonly in the liver and the lung. Hydatid disease in the head and neck is uncommon and hydatid cyst presents rarely as a cervical mass. Cervical vertebral echinococcosis is rare. We report a 14-year-old girl with multiple cervical spine hydatid cysts of the C1-C2 vertebrae that spread into the surrounding paravertebral tissues and involve the nasopharynx and the skull base particularly the left jugular foramen. This process has caused a progressive swelling in the left side of the neck located in the retrostyloid compartment of the parapharyngeal space with paralysis of cranial nerves (VI, IX, X, XI, XII). The diagnosis was made based on the image obtained from CT and MRI examinations. Characteristics of this rare disease, diagnosis and treatment difficulty are discussed.

Abstract
A human nasopharyngeal linguatuliasis was reported for the second time in Egypt. The patient (20 years old male) was presented with main conspicuous complaints, fever, urticaria (face and neck), coughing, vomiting and passage of small (less than 1 cm. in length) worm-like structures in his nasal discharge and vomitus. Symptomatic treatment was given followed by a single dose of praziquantel after identification of the causative parasite. Human linguatuliasis (pentastomiasis) was discussed.

Abstract
This paper presents a case with a 4-month history of nasal obstruction and intermittent epistaxis. The cause was found to be a leech in the nasopharynx by means of endoscopic examination. Leech endoparasitism, although rare, may cause serious, even lethal, complications. A high index of suspicion of leech infestation must be entertained when faced with nasal obstruction and intermittent epistaxis in children, and should be investigated surgically as with all other foreign bodies.

Abstract
Previous reports of Cephenemyia jellisoni Townsend (Diptera: Oestridae) larvipositing onto the lips/lower muzzle of deer, with larvae invading via the mouth, are shown to be erroneous. Additional studies with deer models baited with CO2, 1-octen-3-ol and Deer Trail Scent, and muzzle and nostrils treated with insect adhesive, revealed that only C. apicata Bennett & Sabrosky larviposited onto the lips/lower muzzle; C. jellisoni, by contrast, larviposited into the nostrils. Larval depositions were associated with females of both species observed attacking models. Females of both species also were found stuck on adhesive-treated, baited models not attended by observers. During several seasons of exposure, such models received 89 C. jellisoni larvipositions into the nostrils and 87 C. apicata larvipositions onto the lips/lower muzzle. In laboratory experiments nearly all larvae of both species remained stuck in adhesive within 1 mm or less of where they were deposited.

Abstract
Oestrus ovis (L.) (Diptera: Oestridae), the nasal bot fly, has a relatively short free-living life cycle outside of the host, and therefore it is necessary to know when the parasitic period occurs in order to prevent the clinical signs and economic losses caused by this parasite. The length of this parasitic portion of the life cycle is quite variable: a few weeks to several months depending on the season and climatic conditions. Surveys of Oestrus ovis larval populations in sheep show different results on the number of generations according to the local climate. Mean monthly larval profiles of L1 and L3 burdens of sheep from West African Sahelian countries, Mediterranean countries (Morocco, Tunisia and Sicily) and Southwest France were compared. Valuable information on the suspected extension of the fly season is obtained showing the period of infection in each area. This knowledge will be a valuable tool to help in choosing the right treatment at the right period.

Abstract
Maggot infestation (myiasis) can occur in the newborn baby. However, neonatal myiasis is rare, and there is no published literature on this subject. Rapid useful information on such an esoteric clinical case can be obtained by searching the Internet. Effective medical management includes complete removal of the maggots and offering reassurance to the distraught parents.

Abstract
A survey of naso-pharyngeal myiasis affecting red deer (Cervus elaphus) in southern Spain was conducted. The parasites involved were the larvae of Pharyngomyia picta and Cephenemyia auribarbis (Diptera:Oestridae), which coexist sympatrically within this host. Males and older animals had higher prevalences and intensities of fly larvae. Differences in behaviour and habitat use by male and female deer, and the increase of head size in older males are possibly responsible for this. There were low densities of C. auribarbis while P. picta was the species most frequently observed, although both oestrids were located in the same host cavities. The earlier larviposition by C. auribarbis, and its faster larval development may reflect asynchronous life-cycles of both oestrids; this may decrease inter-specific competition between these sympatric species.

Abstract
A 9 month old female llama was presented with inspiratory dyspnea. Radiographically, there was a large soft tissue mass nearly occluding the nasopharynx. During endoscopic examination three nasopharyngeal bots were identified embedded in the mass. The larvae were removed and the patient treated with ivermectin. The patient was discharged one week later free of clinical respiratory disease. In follow-up radiographs made 6 weeks later, only residual radiopacity in the area of the mass remained.

Abstract
Prevalence and intensity of parasitism by oestrid larvae in the Spanish ibex Capra pyrenaica were determined for a period of 2.5 yr in Sierra Nevada Natural Park, southern Spain. The most relevant result of this study was to find Oestrus caucasicus parasitizing this ungulate in a geographical location far from its previously known distribution, e.g., the Caucasus mountain range and central Asia. Larvae were found within 74% of the heads examined (n = 180). Prevalence was higher in females and in older animals. Lowest prevalence occurred during the summer months. The mean intensity (+/- SD) was 25.4 +/- 27.3 larvae and was similar in both host sexes. The number of larvae increased with host age and reached the highest intensities in winter, during December and January.

Abstract
In June 1993, a yearling female elk (Cervus elaphus) near John Day, Oregon (USA) was observed twice over a four week period with signs of neurologic disease including weakness, walking in circles with an uncoordinated gait and disorientation. The elk was shot, and the head and neck were examined grossly for parasites and lesions. Thirty-five second and third instar larvae of Cephenemyia jellisoni were recovered from an encapsulated space in the nasopharyngeal area dorsal to the soft palate. Larvae protruded into the caudodorsal end of the ventral nasal meatus, obliterating the opening of the left eustachian tube. Larvae were not recovered from their normal location in the retropharyngeal recesses. Thus the effects of several Cephenemyia jellisoni larvae in an aberrant location mimicked signs observed in meningeal worm infections.

Abstract
Nine hundred and twenty-three camels slaughtered at Al-Ahsa abattoir, Eastern Province, Saudi Arabia, were examined for infestation with second and third instars of Cephalopina titillator during the period from December 1991 to November 1992. Four hundred and eighty camels (52%) were infested with second and third instars, with an annual mean of 19.29 +/- 1.09 larvae per camel (L/C). The percentage of infested camels and the mean monthly total number of larvae per camel showed two peaks of abundance, during February (96.06% and 25.06 +/- 2.1 L/C) and September (88.90% and 27.50 +/- 3.97 L/C). Variations in the percentage of infestation were inversely correlated with monthly average temperature and positively correlated with relative humidity. Mean numbers of third instars were significantly greater than those of the second instars during each month of the study period. Two peaks of abundance were observed for each of the second (February and September) and third instars (January and October). Infestation levels showed that the percentages of camels infested with 1-10, 11-20 and 21-30 larvae were 47.90%, 19.16% and 12.71%, respectively. Fewer camels were infested with 31-40 (6.25%), 41-50 (4.37%), 51-60 (3.54%) and 61-70 (2.08%). The greatest number of larvae (101-110) was observed in only three camels (0.62%). It is concluded that adult flies appear twice a year, during the period from late March to early May and in December. Twice-annual larvicidal treatment of camels during February and September is recommended to eliminate most of the larvae infesting camels.

Abstract
Detection of microsporidia in clinical specimens has relied on electron microscopy, histology, or staining. This article describes further alterations to the modified trichrome staining method which make it easier to identify microsporidial spores. The changes are a decrease in the phosphotungstic acid level and the substitution of a colorfast counterstain, aniline blue, for the fast green of the original stain. The modified stain provides good contrast between microsporidial spores and background material including human and fungal cells. Stool specimens from 139 human immunodeficiency virus-seropositive patients revealed that 5 patients were infected with Enterocytozoon bieneusi and 6 patients had larger spores. Thin-section electron microscopy of the larger spores showed a structure consistent with that of either Encephalitozoon or Septata species. Three of the patients with Encephalitozoon- or Septata-like species had disseminated infection, with spores detected in nasopharyngeal aspirates and urine samples.

Abstract
In Mexico, 6 cases of diffuse cutaneous leishmaniasis (DCL) were found in widely separated geographic regions. Information was also available on 2 other cases. In addition to the typical clinical features, half of the patients had evidence of nasopharyngeal mucosal involvement. All isolates from the DCL patients were identified as Leishmania mexicana mexicana by isoenzyme analysis and monoclonal antibody typing. In 1 region of Tabasco state where DCL was found, uncomplicated cutaneous leishmaniasis appeared to be highly endemic, and isolates from a few such patients were identified as L. mexicana mexicana. An incidental finding was the recovery of an isolate of L. braziliensis braziliensis from a patient with chiclero ulcer in Oaxaca state. The clinical and epidemiological significance of the reported cases are discussed.

Abstract
During one year 1249 male cattle were examined for Mammomonogamus laryngeus infections in the slaughterhouse at Kandy, Sri Lanka. The overall prevalence was 40% with only light monthly variations (34 to 52%). The infection rate was highest (47%) in 2 to 2.5 year old animals. In infected animals an average of 6.4 parasite pairs was found with higher numbers in older animals. The majority of worms were located on the posterior side of the epiglottis. Lesions observed were mucosal plugs at the site where the parasites were attached to the mucosa and moderate to severe erosions and ulcers in other zones.

We present a case in a male patient from Indonesia of nasal leech infestation by Dinobdella ferox that had gone unnoticed for at least three months. The possibility of leech endoparasitism should not be overlooked in people presenting with epistaxis or hemoptysis and a history of recent contact with fresh water lakes or streams in tropical regions.

Abstract
All of 116 northern fur seals examined, except black pups (up to 3 monts old), had nasal mites, Orthohalarachne attenuata and O. diminuata, with the mean density of 1,808 mites per subadult male, 435 per adult female, 251 per silver pup, and 21.5 per black pup. Only 63% of black pups examined were infested with both mites. Larvae represented as much as 99% of the total mite population (total samples), and the females of both species of Orthohalarachne accounted for more than 90% of the total population of adult mites. The O. attenuata adults inhabited the nasopharynx and O. diminuata adults were found primarily in the lungs. Larvae of both species occupied the mucus-filled turbinates. The heavy infestation with these mites appeared to result in impairment of respiration in fur seals, and could also cause lesions in the lungs and secondary alveolar emphysems, predispose to more serious diseases, or even kill the host animal.
